Title: dual iso 2,5k movie thread
Post by: Danne on July 26, 2014, 01:45:47 AM
Hi!
Decided to deepen my testing with dual iso movie mode again and created some 2,5k movie files which show what an amazing kind of dynamic range dual iso can achieve. Alex work on refining the conversion tool has been amazing to say the least.
I get the best results when in 3x zoom mode. (less aliasing, cleaner picture). 3x zoom mode is closer to dual iso still photography.

5D mark 3 magic lantern (nightly build)
dual iso movie (mostly 100-1600 iso)
3x zoom 2560x1090 raw
hacked preview
24 fps override

Lenses used:
Samyang 14mm f2.8
Canon ef 85mm f1.8


Movie and workflow description

Movie (Watch in 1440HD)

Below app and workflow service will apply same level(avoids flicker after dual iso conversion) and work multithreaded (run 4 conversions simultaneously).

So let,s start making more dual iso movies and put it up in this thread. Workflow tips and other useful information are also welcome.
2,5k 24fps will probably only be achieved with the 5d mark 3 but other aspect ratios are welcome as well of course.

Thanks to Alex and all other contributing on this forum.

Danne this is great stuff!  I got very excited watching your workflow and how seamless it seemed to be that I went out to tried dual iso in movie mode for myself over the last 2 days.  Unfortunately following your steps one by one, I've been painstakingly getting 0% success trying this the last 2 days.  I've read countless forums, watched video tutorials, and walked through several different processes that have all been unsuccessful for me.  MlvMystic doesn't do anything to to my DNG's after it's processed through dual iso, and I haven't been able to get anything other than the alternating (flickering) image as a final result.  Any light you could shine onto the errors I'm having would be huge!  Thank you in advance!

my unsuccessful workflow thus far -

5dmk3-1.2.3 july 17th build

ML HDR video - ML.raw file
Raw Magic lite - process to DNG
MlvMystic - process DNG's in "dual ISO" mode
Open DNG sequence in AE or Davinci for final grading / exporting

I'm currently yielding nothing but a flickering image
Title: Re: dual iso 2,5k movie thread
Post by: Danne on July 27, 2014, 09:49:18 PM
Keep on trying. Next time without HDR selected ;). HDR is a whole different ballpark.
Instead set "dual iso" on and choose something like 100-1600 and see to it you get well exposed highlights. Film in raw or mlv and follow my steps in the workflow as a starting point.
Good luck and post some results later :)

Another small test lifting shadows retaining highlights. Used a canon 20-35mm f2.8. Next up is to get a wideangle which will give around 22-24mm 2560x1090. Would be nice for interiors. Thinking about modifying a sigma 10-20 and move it a little to get a centre spot which will be needed for correct perspective.

Hi!
How many seconds continuous you can take with 5x?

Some frames are corrupted.  Strange things appear, example: 1 min 38

Have you reduce the noise in the shadows?

thanks.

Hi, slog2 is a video format using s-curve to optimize the video for maximum DR. So this is not the logfile. The Sony high end camera's use slog2, canon does not. But using Davinci Resolve we can convert Canon RAW into s-log2 format.

Incredible work Danne!

I have one question though: when you shoot video with dual ISO do you have a strong impact on resolution as with stills?

Thanks for your feedback!
Title: Re: dual iso 2,5k movie thread
Post by: Danne on August 10, 2014, 09:13:52 PM
Thanks. I think it works the same as with dual iso stills but in 3x zoom mode.
Title: Re: dual iso 2,5k movie thread
Post by: morsafr on August 10, 2014, 10:05:42 PM
You can only shoot in 3x mode?
Title: Re: dual iso 2,5k movie thread
Post by: Danne on August 10, 2014, 10:26:49 PM
No, you can shoot in regulat mode as well. The quality will differ and also you cannot do 2,5k.

New findings. Adobe camera raw used through AE seems to create flicker with dual iso movie files without even using the sliders at all. Tested some clips and compared acr with mlrawviewer which created no flicker at all. Here is a comparison.
*Davinci resolve 10 lite also has the flicker so it seems it comes from the conversion to dng from dual iso dng:s. Somehow it works with Mlrawviewer??

A.D has compiled an app here. Don,t know if you need some additional files.

https://bitbucket.org/a_d_/magic-lantern/downloads/

If you have lightroom you could try this
http://www.magiclantern.fm/forum/index.php?topic=11056.0

I,m searching for something which gives same level on all the files right now. Not to used in using tools like exif tool or terminal but Alex has developed some sort of command to get them to develop with same black and white level. This will prevent flicker from occasional files.
Title: Re: dual iso 2,5k movie thread
Post by: Markus on August 18, 2014, 11:10:52 PM
Thanks I'll check those out. I'm  trying ML RAW Video Converter 1.9.2 right now. Didn't get it to work first because need to click the dual iso clip and enable dual iso processing. Slow processing though and only using 15% of the cpu capacity. Some settings here on processing also but they are greyed out. Chroma smoothing is something I would like to avoid I wonder if that is on or of when the option is greyed out like that.

So, managed to get the "same level" to apply on a whole folder by following first this video



Then apply following code in terminal.

Quote from: a1ex on May 06, 2014, 11:33:20 PM
Right, using --same-levels with parallel processing is a little harder (because all the files are analyzed at the end, and then it decides a white level that hopefully matches all of them). But it can be done after a regular conversion, like this:


exiftool *.DNG "-WhiteLevel<BlackLevel"
exiftool *.DNG "-WhiteLevel+=50000"


You may need to fiddle with the values though; lower the value if you get pink highlights, increase it if you think you can squeeze some more highlight detail.

Made a super quick test that looked nice. Thinking on filming a side by side with two mk3s. I'm interested in getting a feel for when I would rather have the dynamic range then full res.    I'm betting there are a whole lot of situations where this mode could be useful.

Did a quick and dirty test of dual iso vs normal mode in a scene with extreme dynamic range. I think I would prefer the 1600 iso version with full res in a situation like this. I think the windows look quite good almost blown out but with some detail still there.



I shot it all in full hd. Developed in resolve 11.I was experimenting with high res low fps for timelapse just before this so I still had 5 fps on if you're wondering about the fast movement.
Title: Re: dual iso 2,5k movie thread
Post by: Danne on August 21, 2014, 09:48:12 PM
Cool. Thanks for sharing.
I tend to use acr and despite what is said about flicker I work with the highlight sliders to retain highlights. I simply couldn,t get resolve to save highlights the way I wanted to. Also doing all dual iso testing in 3x mode for reducing aliasing and other artifacts. I even modded a 8-16 mm sigma to get a good wideangle for 3x mode. I,ll put up some material later on.
Title: Re: dual iso 2,5k movie thread
Post by: Markus on August 21, 2014, 10:43:27 PM
I tryed som 2.5k x 1290 or something like that but still got aliasing with the higher res files. Maybe I should test the same files with acr to se how if it handles the dual iso files.
Title: Re: dual iso 2,5k movie thread
Post by: Danne on August 21, 2014, 10:47:15 PM
Yeah, there is still aliasing and such but should be muchless than in normal mode. You,ll notice the difference when you move around and film critical situations.
Title: Re: dual iso 2,5k movie thread
Post by: Markus on August 22, 2014, 12:37:54 PM
Tried to process the dual iso 2.5k file in ACR but the aliasing issues were only worse there. Wondering if there are settings to be tweaked in the dual iso interpolation process...
Title: Re: dual iso 2,5k movie thread
Post by: a1ex on August 22, 2014, 12:50:12 PM
Can you upload a few DNGs and 100% crops to show the issue?

In theory, aliasing should only appear where you would otherwise get clipped details at the higher ISO, and - to a lesser extent - where you would have lots of noise at the lower ISO.
Title: Re: dual iso 2,5k movie thread
Post by: Danne on August 22, 2014, 06:07:42 PM
Short test shooting in dual iso in normal mode(1920x1080) using a 20-35mm vs 3x zoom mode(2240x1260 to match the wideangle) using a modified sigma 8-16mm lens.
Question is if the difference is that big here when it comes to aliasing. Here is a few original dngs from both clips if anybody is interested.

Maybe my situation was a bit too extreme for overlapping. I used 100/1600, it warned that it might be too a agressive in menu. I'll try to upload something tomorrow. Used fps overide at 5 fps at the same time but that shouldn't  matter...
Is chroma smoothing always on when you interpolate the dual iso dng to a usable one?
Title: Re: dual iso 2,5k movie thread
Post by: Danne on August 22, 2014, 10:26:19 PM
Hi Markus.
I use Mlvmystic mostly. Don,t think chroma smoothing is an option when clicking the dng tab? Or what do you use to convert?
Title: Re: dual iso 2,5k movie thread
Post by: a1ex on August 22, 2014, 10:39:26 PM
Please don't use MLV Mystic. It's not just a GUI over cr2hdr - it's closed source, so I have no way to know what exactly it does (besides licensing issues). It's likely based on a very early version of cr2hdr, from those times when it was included in raw2dng.

So I don't accept any issue reports if you use that program. You can post in the MLV Mystic thread if you want, but the app seems no longer maintained.

You can use the Lightroom plugin, or BarracudaGUI, or the batch processing scripts - those are just GUIs that call my binary, so the output is done with my code, which I can troubleshoot and fix.
Title: Re: dual iso 2,5k movie thread
Post by: Danne on August 23, 2014, 12:54:50 AM
Hi Alex! Sure, no problem. So, let me shed some light here about my concerns. Problem is I have to crop the picture in 3x mode with recent cr2hdr. That is the main reason I used Mlvmystic.
Issue report.
https://bitbucket.org/hudson/magic-lantern/issue/2091/cr2hdr-dual-iso-3x-zoom-mode-strange
THe border issue has been there since december 2013. Only in 3x zoom mode.
The A.D converter also don,t seem to work with as high resolution(or quality) as in lightroom default settings or with Mlvmystic. At least not when I compared them. Isn,t A.D version very old? It says 2013-12-07. https://bitbucket.org/a_d_/magic-lantern/downloads/.
Until now I,ve been using Mlrawviewer or Rawmagic to convert my files before converting the dual iso. I,d love to use lightroom or A.D without the bottom border issue again.
Thanks for everything.
/D

Post by: Danne on August 30, 2014, 09:37:41 AM
Trying to understand basic terminal commands in exiftool and found out that if you add the line -overwrite_original to the same level commands exiftool stops keeping the original of every single dng. Of course, store the original somehow if it is a critical dual iso movie file.

exiftool *.DNG "-WhiteLevel<BlackLevel" -overwrite_original
exiftool *.DNG "-WhiteLevel+=50000" -overwrite_original


*update, added -r (recursive to let the command search through folders)

Exiftool -r *.DNG "-WhiteLevel<BlackLevel" -overwrite_original
Exiftool -r *.DNG "-WhiteLevel+=50000" -overwrite_original

1 - open terminal and write Exiftool -r *.DNG "-WhiteLevel<BlackLevel" -overwrite_original then hit space once.
2 - drag your folders or a single folder containing more folders on top of the terminal command (command -r will search all folders). Hit enter. Command line will run through the DNG;s. Wait until all files are finished.
3 - run the same again but now with the other command line Exiftool -r *.DNG "-WhiteLevel+=50000" -overwrite_original hit space once.
4 - drag your same folders or a single folder containing more folders on top of the terminal command (commando -r will search all folders). Hit enter.

Terminal might be giving some warnings about not finding dng,s but the command seems to run anyway.

If someone knows how to do this in a single command please tell.
This way I get the same level on my dual iso movie files without keeping the extra original and with some sort of batch processing but in two steps.

Danne: did some more tests with barracuda gui as processing interface. Really liked the multi processing speed. Got problems with exposure jumps and the bottom border issue. Have you found a way to solve those issues?
Also do you know how to open the settings page for barracuda gui?

You could try the command lines above to and they will probably create the same level for your pics. Can,t help you on windows stuff cause I,m on mac unfortunately.

Lens: Canon EF 17-40mm L
shooting resolution: 2560x1090 at 23,976fps
(3x crop mode, resized at 1920x818)
Dual-ISO: 100-800 most of the clips, one at 100-1600 (the grass in backlight)
graded in Lightroom 5 - h.264 encoding with AE

I put the first free-music I found!



What do you think about?

I can only shoot for a limited time (frame skipping disabled), trying changing some settings and disabling features in ML to get longer clips, but the longest I've been able to do was 12 to 20 secs.

I used MLV Mystic for raw to dng, dual-iso convertion with cr2hdr-20bit (drag-and-drop old-school-method :)).

Then, I tryed to fix flickering with ExifToolGUI: the black level of almost all clips was already fixed at 8192 (so fix not needed), I only changed white level to 65128 (I found it is the maximum, so I always choose this value, seems like it gives more white details).

But I still see flickering! Also, in thoose clips that I moved from light to dark areas and viceversa, the exposure gradually changes (I think "gradually" thanks to the ExifTool fix): it becomes brighter precisely in the lighter areas!
WHY? Can anyone explain it? Any suggestion to avoid it? I tried to fix it in AE, but I think is it still visible...

Danne, the mod of the sigma 8-16 sounds brilliant! As it is a lens for APS-C cameras, I imagine that the mod affects a sort of shifting to center the lens as much as possible on the 3x-crop-mode center, right?
Really cool! I can't wait to read something more about this opportunity!

Cheers!

Nicely filmed. Good composing, wonderful surroundings. Gives a more photographic feel. Hope Alex is watching :).

To get more seconds try filming without liveview. Hack on.

The flickering could be because of grading in adobe camera raw. Since you use the the 20-bit binary drag and drop method I think
you could call the --same-levels command implemented by Alex to get a same level conversion in the conversion stages.

terminal: cr2hdr --same-levels dng enter

Check this mod of 8-16mm to get a better centre spot giving me around 22mm wideangle :)

Thank you! I forget to say, some clips are stabilized in post...
Without liveview? you mean Powersave options in ML menu? What other options you suggest? I normally shoot 2.5k with theese:
Canon options off (auto lightning, noise reduction, etc.)
MLV sound off
Dual-ISO -3 or -4
Exp. override on
Exp sim. on
GDraw off (after taking exposure)
FPS override at 23,976
Shutter fine-tuning - to match 180°
RAW MLV on 2560x1090, aspect 2.35:1, Preview ML Grayscale, Status none, SRM job memory on, extra hacks on, fix black on, Card spanning on, Reserve card spase on, leaving the rest to default values.

Sorry, or it is too geeky for me or I'm too slow for that... anyway, it's the same :)
I'm on windows (I think the "terminal" is referred on a linux machine...?), can you suggest me a way to eliminate flickering (or explain me better this "--same-levels", or any helpful link in forum)? Any good alternative te ACR to suggest?

Thank you!

Great job with the sigma! 22mm on 2.5k 14bit video with a 5D3... wow! unbelievable! The only thing missing it would be a global shutter ;) but I think this will be impossible even for you ML genius! Who knows, may be one day!

Not sure how to work the cmd, sorry.
Someone simply renamed the cr2hdr file to cr2hdr --same-levels and used the drag and drop. You could try that. More info to find here.
http://www.magiclantern.fm/forum/index.php?topic=7139.2025

You have preview modes in raw settings. There is one setting called hacked which will freeze the live view and give you about 10mb extra memory.

Would also like to know how to do the same levels command in Windows? Danne you suggested just renaming the cr2hdr to cr2--same levels?
Title: Re: dual iso 2,5k movie thread
Post by: Danne on September 22, 2014, 05:41:15 PM
Found this in a thread once. In here somewhere. http://www.magiclantern.fm/forum/index.php?action=search2

"NOTE FOR THOSE WHO DO NOT KNOW ABOUT RUNNING PARAMETERS, make a shortcut of the "cr2hdr-20bit.exe" file, right click on shortcut > properties, in the target, copy and paste  --same-levels at the end of the taget, if the target has spaces in the url, put " at the beginning of the url and at the end of it, for example:
"C:\camera raw dual iso converter\cr2hdr-20bit.exe"  --same-levels
putting this info here to save time for people who dont know (like me)

also do you know anyway of evening out the flickering in the dngs after processing them with the old cr2hdr that didnt have the same levels parameters"

Excellent Video @Danne and I will definitely need to upgrade my LR5 plugin because I do not have the extra features that cr2hdr 20-bit gives you... THANKS for the wake up call that I absolutely need.  ;)

Made another video using dual iso 3x zoom mode. I made progress in using acr in postproduction. I totally skipped using highligt recovery and shadow sliders etc. Only temper with white balance and exposure and only use the tone and point curve for highlight, contrast etc. It works really good and without flicker.

Awesome clip!!! Whats lens did you use with the 3X crop?
Title: Re: dual iso 2,5k movie thread
Post by: Danne on September 30, 2014, 06:50:32 AM
Thanks. I use a modded sigma 8-16mm (see bottom page 2)

I'm curious to see 22mm on my 16-35L w 5D3 on the gimbal TYTO that I can borrow from work and compare that with your beautiful modified sigma! So jealous... ;)

Hello Danne,

I just processed my dual iso DNG's in Lightroom but there is one problem. It seems that every alternating DNG has a different white balance color despite all of my DNG's being synced to have the exact same white balance. One has a green tint and the other a pink tint. Did you have this problem?
Title: Re: dual iso 2,5k movie thread
Post by: Danne on October 01, 2014, 12:29:11 PM
What camera are you using? Could you put up a sample dng?
Title: Re: dual iso 2,5k movie thread
Post by: senzazn12 on October 01, 2014, 03:08:06 PM
Camera is a 5D Mark III. I used the CR2HDR20BIT algo through Magic Lantern RAW Video Converter 1.9.2 to process the MLV files to Dual Iso DNGs. Then when I opened up the DNGs in Lightroom, despite syncing them all to have the same white balance, each alternating DNG frame has a slightly different white balance. Here are two sample DNGs.

https://www.dropbox.com/s/kimafdub1vm9pm0/MLV_A002_271841_C00016.000000.dng?dl=0

Post by: Danne on October 01, 2014, 04:56:04 PM
Could you also upload the two dual iso dng-files prior to conversion?

This is information about whitebalance from within the cr2hdr20bit binary

"White balance:
--wb=graymax    : set AsShotNeutral by maximizing the number of gray pixels (default)
--wb=graymed    : set AsShotNeutral from the median of R-G and B-G
--wb=exif       : set AsShotNeutral from EXIF WB (not exactly working)
--wb=%f,%f,%f   : use custom RGB multipliers (default 2,1,2)"



That is strange. One is greener than the other. When I look at the exif information I see a difference in asShotNeutral but I have no idea if changing this will help. Tried to but it didn,t seem to make any difference. My guess is the cr2hdr is applying some algorithms on whitebalance when converting dual iso files but I am not sure. Here is the information from both files if someone elese wants to have a look.

It seems that every alternating DNG has a different white balance color despite all of my DNG's being synced to have the exact same white balance.
Quote from: senzazn12 on October 01, 2014, 03:08:06 PM
Then when I opened up the DNGs in Lightroom, despite syncing them all to have the same white balance, each alternating DNG frame has a slightly different white balance.
I presume you actually mean to say that you are syncing them all to have the same levels (i.e. the "--same-levels" option).  That is not the same as syncing the white balance.

Quote from: Danne on October 01, 2014, 04:56:04 PM
That is strange. One is greener than the other. When I look at the exif information I see a difference in asShotNeutral but I have no idea if changing this will help. Tried to but it didn,t seem to make any difference.
I can't look at the DNGs right now, but a white-balance difference is definitely due to the differences in the AsShotNeutral tag, and setting the AsShotNeutral tag to the same values should make the white balance the same in the two DNGs.  So, something may be throwing off the default "graymax" white-balance calculation, although I don't know why it'd occur on alternating frames.  As a guess, are you shooting both dual ISO (alternating ISO between pairs of lines) *and* HDR (alternating ISO every other frame) at the same time?

No HDR was not turned on. Just dual iso and MLV.

Yes I do. Uploading them now.

Here they are. It is weird because all the odd numbered frames  (1,3,5,7 and etc.) look the same when it comes to white balance) and all the even numbered (2,4,6,8) seem to match when it comes to white balance. Here are the two DNGs prior to Dual Iso conversion.

Same problem as before. Although the "asShotNeutral" settings are exactly the same in the original unprocessed dng:s. Maybe try export the mlv to dng with mlvrawviewer or using the mlvfs method. I still havn,t seen this type of problem with my camera.
Title: Re: dual iso 2,5k movie thread
Post by: ayshih on October 01, 2014, 08:30:10 PM
The AsShotNeutral values in the unprocessed DNGs are the same because they're just default values that don't take into account the actual photo; the white balance is determined in the processing stage by cr2hdr.

I don't have a camera that can do dual-ISO video, so I was surprised to see that the unprocessed DNGs have different brightness patterns: "ddBB RGGB" for 0.dng and "BddB RGGB" for 1.dng.  That is, it looks like the set of lines that are the primary ISO actually switches from frame to frame.  Is this true for all dual-ISO video?  Or is this some consequence of the 5D3 pixel binning?  Whatever the reason, this behavior may be what is causing the white-balance calculations to oscillate.

I think you,re right Ayshih.
Here is two of my dng;s. The lines are exactly the same pattern on these contrary to senzazn12. I shoot in raw but I don,t think I got the issues with mlv. Can,t be sure. Gotta do some more testing. I used a different aspect ratio here as well.

You are right ayshih. I've noticed this in my dual ISO experiments with MLVFS. On my 60D whenever I shoot in crop mode the dual ISO lines alternate through all 4 possibilities => ddBB, BddB, BBdd, dBBd. In regular mode it seems to be the same in every frame.

I see. So it happens in crop mode (for Windows users)? I'll test tomorrow using dual iso in regular mode to see if I get same result when I was shooting crop mode.

Post by: Danne on October 02, 2014, 06:42:46 AM
Looked at my dual iso 3x crop mode files and did indeed see two different patterns also for raw. For mlv 3x mode I see 4 different like dmilligan already stated. COuldn,t really notice any notcable variations on whitebalance though in mlv and raw. Did not shoot a lot in mlv yet so there could be situations where it could be a problem maybe.
Raw gave a slight variation on white balance on the files. TWo different could be find for raw and I think four different for mlv in acr. Variations are very subtle.
So, white balance is also affected but maybe not noticable i most cases. I couldn,t say that it have affected my files.
If affected than it would be nice to equalice those levels the same as white and black level.

Danne, how are you getting such clean footage without aliasing is my big question? I understand the 3x crop thing, but if for example I shoot in my backyard, I get crazy aliasing on the shingles on top of my garage, the brick wall, etc.

Your stuff is great, mazel tov.

Hi Dubzeebass, nice to hear from you. Funny, I finished a recursive script workflow like the one you worked with converting mlv files today :).

Yeah, I manage to get some good footage. What camera do you use? I think 5d mark 3 is the one if you want the cleanest results. I don,t get perfect, I also have aliasing and such. Chromatic abberations too. Some of it I can fix in acr but not all.
Would be nice to se an example.

I think it works on most cameras. In first post are some descriptions on how to convert your files. Mac mostly.
Turn on dual iso, find your highlights at low iso, 100 is good and lift shadows with the other iso, around 800, 1600 iso.

Need some help in diagnosing it. Can you take a few silent pictures with exactly the same settings?

(to avoid this effect, fine-tune the FPS until the image gets stable, but the converter could handle this better)

Some freshly made dual iso movie files. Here are some screencaptures for viewing. Dynamic range is mindblowing with cr2hdr20bit.
Used a1ex cr2hr20bit, filmed in RAW 2240x1260, 3x zoom, 24fps, export AE ProRes through ACR.
Converted raw and dng dual iso through this app.

To Recap,  Have managed to get the individual images to work though do have to unzip Cd2hdr each time an use a fresh copy. The results are stunning will try and up load a couple for you to see.
Have tried to use this with video but  having no joy.  Is there a different programme that I have to use?

My Camera is canon KISS 4 550d. and at this point in time am having to use  Windows Movi Maker as am unable to change my Laptop Graphics card.

This link should direct you to version 1.3.
https://drive.google.com/file/d/0B4tCJMlOYfirdXZyeFc1MHNZU2c/view?usp=sharing

Extract the zip file. Install binary pack following instructions. In the first folder there is an automator icon called cr2hdr-r (pic of a bird).
Drag that somewhere onto your computer and double click.
Choose a folder with raw, mlv , cr2 or dng files and if you installed binaries it should start converting.
Get back if not working.

Just for the sake of it... decided to do a quick test at Dual-ISO 2.5k with the latest nightly (1/3/15 build) for 5D3 1.1.3 and apparently RAW write speeds have increased.

((MLV is just about the same if not slightly better)) <--- according to my KB card.

5D3 RAW (HaCKeD preview) @ 30fps (FPS Override to 25p) -- This one is pushing @ 109.6 MB/s with a KB 128gb 1066x card...

Hi Danne!

I think I had a good idea based on your mod of a Sigma 8-16mm:

Quote from: Danne link=topic=12796.msg127357#msg127357
Check this mod of 8-16mm to get a better centre spot giving me around 22mm wideangle :)

I'm considering to buy a used Nikon version of that Sigma lens, using it with a NikonF-to-EF adapter that comes with an aperture lever, and modding this adapter (aprox. $25) instead of directly modding the lens (aprox. $500)!!!. This way I'll be able to better control the aperture and also the mod whould not "injure" the Sigma lens (for better re-sell it in the future).

What do you think about it?

Thank you in advance for your kind attention and reply!

@lureb74

Lorenzo -- Using Nikon F mount manual lenses on Canon bodies is a standard practice in stop motion animation. Nikon G adapters make up for the lack of an F-stop ring on modern Nikon lenses by controlling the aperture via a lever. Of course you already researched this. I have tried these adapters and you should know the trade offs. Of course there's no electronics communication so no auto focus, there's no feedback on what F-stop you're on and the distance from wide open to completely stopped down is very narrow. I would suggest you get a Nikon G to Canon EF adapter first and see if it is possible. Looking at the photo of the mod and how far it needs to shift I don't think the Nikon adapter will work.

An alternative if you want to be able to go back to un-modded is to see if it is possible to purchase a mount from Sigma or from a camera repair shop.

I also checked around for other alternatives but it seems that the Sigma 8-16mm is probably the best choice for a moderately wide angle lens using crop mode on the 5D3. Interesting that it is an APS-C lens but it has an EF mount and not an EF-S mount. That's one less mod you need to deal with.

@Danne

I haven't tried this yet but isn't it possible to pan around the frame in crop mode on the 5D3? That way you won't need to mod the lens?
Title: Re: dual iso 2,5k movie thread
Post by: lureb74 on February 18, 2016, 04:47:57 PM
@dfort

Yes, I get the same conclusions watching closely to those adapters, and I think I'll not be able to modd it! Your suggestion is good, may be I can switch back to a regular EF mount by asking a replacement from Sigma, the only problem is that in Italy is very difficult to find Sigma spare parts... mmm... Anyway, thanks to Sigma that make APS-C lens that fits in EF bodies too!

Unfortunately, the modd is needed because on 5D3 the 3x window in crop mode is not really free-to-positioning around the frame: I don't know why (but I'm pretty sure there's an obvious technical reason!) you can't put the cropped window in the main center, but a little angled (upper-left, upper-right, lower-right or lower left), and doing this with an ultrawide lens it result in a visible distorsion...

Actually, it would be great if it would be possible to put the 3x crop window right in the center!!!

It's possible (http://www.magiclantern.fm/forum/index.php?topic=16432.msg162189#msg162189), at least 1920x1080x24fps :)

Nice that you got it working through the register. I tried a while ago but never really got it working. Now how to get this into unified? It is kind of a game changer.

@mothaibaphoto ... Would you mind sharing us your working copy of the compiled version for 5D3 113 so we can test it out?

If we like it then I'll start compiling them. But don't you think this should have already been included in the recent nightlies?

As far, as I understand, moderators doesn't encourage sharing user compiled binaries. All such messages with links was deleted.
It's really easy work, moreover if you did it before.

That's why we share via PM but either way no problem I'll see if I can follow the directions provided by the link you just shared. Thanks!

Yes, right! :)

Well... may be the fault is for my "scarse" english (always google translating for helping me writing in these threads) or for my unknowledge of coding stuf, but I REALLY don't understand the recipy!

I think I'll need to wait some more time, checking threads and builds... except that someone wants to share some "simple" solution via PM ! ;) I'll be available to experiment and post the results!

Really? I've been sharing my compiled binaries for a while and never had a problem. I've been posting them on bitbucket where the ML source code is hosted so that might make a difference.

So let's see if I can follow this:

1. http://www.magiclantern.fm/forum/index.php?topic=15894.0

Hey, that's my post on how to setup a Cygwin/MinGW-64 development environment--ok, check.

2. Merge iso-research with unified.
The idea was taken here: http://www.magiclantern.fm/forum/index.php?topic=10111.msg129237#msg129237

Ah--a note from a1ex. Not too difficult to follow but hasn't the fullres-silent-pics branch already been merged into unified?

QuoteTry merging the fullres-silent-pic branch with the iso-research branch.

If you don't want to merge, compile the fullres-silent-pics branch as usual, with CONFIG_GDB=y, then compile only the extra modules from iso-research.

3. Here is how to enable: http://www.magiclantern.fm/forum/index.php?topic=10111.msg145036#msg145036
Viola, centered FHD crop, color and realtime, and with ext. monitor too, continuous with decent card.

Uh--this one is going to be a bit more challenging.

Quote from: a1ex on April 14, 2015, 07:51:46 PM
For 5D3, a configuration that appears to work is:

CMOS[1]                 0xB8B           vertical position and size
CMOS[2]                 0x10E           horizontal position and downsizing factor
CMOS[6]                 0x170           ISO related? pink highlights without it
ADTG2[0x8000]           0x5             it's 5 in zoom mode and 6 in 1080p
ADTG4[0x8000]           0x5             same
ADTG2[0x8806]           0x6088          without this, you get some weird artifacts
                                        note: ADTG4[0x8806] should not be changed (default 0x6048)


How to apply it:
- compile ML for adtg_gui (see first post)
- load adtg_gui and enable it in Debug menu
- go to movie mode 1080p, 24 or 25 fps
- go to play mode and back
- configure the registers in adtg_gui submenu (latest adtg_gui has a preset for crop mode registers)
- go to play mode and back (again)

Minor bug: it has a few black lines at the top.

I can give it a go--or if you have a bitbucket account with a branch that has most of this already merged and ready to compile it would be greatly appreciated if you could share a link to that branch. I don't mind compiling and sharing it.

@dfort:
I didn't write a line of code, have no (yet) bitbucket account (but plan to get one if I will suddenly code something)
I will share my expirience with this find in "CMOS/ADTG/Digic register investigation on ISO" thread. 
But all this discussion is completely off topic here(sorry about that) -
no DualISO or 2,5k movie this way :(
One note: you miss the point - required functionality(adtg_gui module) in iso-research, not fullres branch.
Title: Re: dual iso 2,5k movie thread
Post by: Danne on February 20, 2016, 10:33:51 AM
Yeah. Adtg_gui module and then tweak settings. I,m not to familiar with how to work it but I understand that settings done in adtg_gui will revert to original state upon restart? I,d be happy to see some action on this in your thread motbaiphoto. If it,s nicely working I would love to see it in the nightlies.
By the way. Last I tried I had some border flicker but I didn,t test too much.

Oh, so the idea was taken from that but don't do that, do this: "Merge iso-research with unified." Ok, simple enough.

I'm almost at the grasp of compiling this ... I keep getting a few errors via Terminal ... I don't understand why can't @mothaibapoto share this with a few of us to test it out and speed up the process of getting this to finally merge into the nightlies.

This is a team effort ... anyone else agree on this matter?

Not tying to sound obnoxious but it's the truth.

Ok--here we go. I posted a build for the 5D3.113 which is what I believe most people are using for 2.5k movie files.

https://bitbucket.org/daniel_fort/magic-lantern/downloads

magiclantern-Nightly.2016Feb20.5D3113_adtg_gui.zip

I was hoping to get away with just handing off the adtg_gui module but it doesn't work with the current unified branch.

I'm rather new to the 5D3 and haven't tried 2.5k dual iso yet so maybe someone with more experience can give it a try and report back? (Team effort?  ;))

Thank you so much. Always wanted to play with adtg_gui!!!
Usually I'm compiling ML in linux but never tried other branches or merging them. Have not gotten to that point ever :)

I tried to download this, but I find that the dual iso feature is not working... well, actually I only try it in photo mode, but since I needing that feature I switch to the latest build (02/24), in which the dual iso feature is working regularly. So, I don't even try to use adtg_gui for any testing...
Title: Re: dual iso 2,5k movie thread
Post by: dfort on February 26, 2016, 04:11:47 PM
That may be one of the reasons why adtg_gui isn't in the nightly builds. This is for developers, experimenters and users who like living on the edge.

"Not working" is not that easy to reproduce. You might tell us your settings first and which error you got.
Title: Re: dual iso 2,5k movie thread
Post by: lureb74 on February 27, 2016, 04:15:10 PM
Ok, not working: I mean, I loaded and enabled the feature as normal, using a +3 value and setting ISO to 100 (I can see 100/800 in live view) but the stills are exposed only at 100. So, no interlaced files, no 100-800 lines!
I refer only to this version of ML:

What ml firmware build are you using? Camera settings? What program are you using to develop the dng files?
Upload a sample file?
Title: Re: dual iso 2,5k movie thread
Post by: Sirius on April 23, 2016, 06:47:00 PM
Thanks for the fast reply!
I just made a Dropbox folder with the programs i used and a DNG file before and after the cr2hdr convert.
I filmed in 1920 x 1080, f 16  1/50 sec , ML Raw(MLV) , dual ISO
Global draw : off
Use SRM job memory : on
extra hacks : on
buffer fill method : 4
CF-only buffers : 1
Reserve card space : on
Dual Iso 100/1600
Auto WB
I opened the converted dngs in After Effects as Footage and interpreted it with ACR. afterwards i opened the project in Premiere Pro.
I use the ML Nightly Build for 5D MK III Firmware 1.2.3
there are theses cruel artefacts in the picture and the pink frames. 
By the way, if I try to film in crop mode, it's totally failing and stopping after 2-4 secs because of frameskipping.

@DeafEye, any thoughts on monitoring while shooting 2.5k continuous with Hacked Preview? Is there a workaround for being able to see what is actually happening on screen?

Thanks

Post by: Danne on April 24, 2016, 08:53:47 AM
@Sirius

Download the latest nightly build for your camera. At least for 1.1.3 the pinkframe issue is gone. I think 1.2.3 is fixed too
You should film in 3x zoom mode to lessen artifacts. It will default to 30fps so you have to set fps override to 24 or 25 fps.
If you experience small flicker in sequences it will come from white levels not being linear coming from cr2hdr processing. THis can be fixed with exiftool. You could come back here once you sorted out the other things.

Post by: Jin Kim on June 30, 2016, 06:55:43 PM
Hi.
I have 5D2.
I'm confused between dual iso and hdr video recording with 5d2.
When I set up dual iso in magic lantern menu, the video taken did not show any vertical line that I can see when I took dual iso picture. Also, when I take HDR video with my 5d2, the video taken shows blinking (light and dark) video.
Here are my questions.

1. Is it possible to take Dual iso (not HDR) video with 5d2?
   1-1. Then, please let me know how to set up the menu to take it.

2. If Dual iso video is not possible to take with 5d2, please let me know how to convert the HDR video that I took to convert DNG in Mac (I converted the video to dng files but one picture is bright another one is dark the next one is bright...).

Thank you in advance!

Jin
