General Chat / MAGIC LANTERN - my close friend
« on: February 10, 2020, 12:24:38 PM »
Magic Lantern has become for me like an exquisite pair of gloves. In whatever way you move your hands they are just there, snug, close fitting and gently warming your hands helping you in any way needed to do your work...
Thanks again for all your work and effort in producing such a fantastic tool and on top of it all just for free
Being an artist not getting much money from my films I am really grateful for this tool that makes my work keeping a high quaility without costing a fortune (working with a Canon 5D mk III that I got cheaply
because its shuttercount had passed 500 000!! Keeping my thumbs for it to continue to work...)
/ olof 😀

PS I look forward to an eventual continuation on mk IV (more fps/higher resolution)....DS

Thanks a lot masc - grateful  :D :D

Is it possible to see the exposure metadata in MLV?
/ olof 😀

Thank you DeafEyeJedi (sorry for misspelling before...),
About the build - it is the Nightly.2018Jul03.5D3123

PS not that cold - a couple of centigrades above!!!
/ olof 😀

Great Masc  ;D ;D

...and I who just thought I had to switch on the Dual ISO button!

Maybe share some trimmed samples of your original MLV shot in Dual-ISO for us to see and test with @olofen?

Here you are DeaEyeJedi, really hope you can see something:

I just used DualPixel for the first time
Unfortunately I did not get the result I wanted…
I use a mk III and compared two exposures - one with and one without Dual Iso
Dual Iso was set to +2 EV
In MLV app 1.5 I clicked on force on The Dual Iso file and then set it to on
Then I processed the two files (that looked identical in MLV…) to two H264 movies, opened them in Photoshop and compared
BUT I cannot see any difference in the shadows!!!
What did I do wrong?

General Help Q&A / Re: ML'd 5D Mk III for narrative filmmaking
« on: January 31, 2019, 10:40:14 AM »
If you set up the 5d3 for “normal” raw recording, in my opinion it is optimized for narrative. You cant get TC out anyways, so there is not much hocus pocus “optimizing” it for narrative work. Optimizing for narrative work with the 5d3 is more about preparations around the camera like with any camera.

I recommend Firmware version 1.2.3 for clean hdmi output.

The modules you need: Mlv_rec, mlv_play, Mlv_snd, File manager. Or if you are a familiar with ML then I recommend 22. July experimental build for lossless 14 bit, which will require some other modules loaded.

Set raw recording on, resolution 1920x1080 (mlv vanilla, continues)) with lossless 14 bit set to 1920x1280 for extra space of reframing.

Set fps override to Exact FPS at 23,976/24.000/25.000 (your preference)
set your Shutter Fine-tuning to get 180 degree shutter. E.g. 24.000 fps set shutter fine tuning to 0.86 for 1/48th.

Make sure mlv_sound is on

Turn on Raw Zebras (must have)

Dont use the waveform unless you shoot h264.

An external recorder is necesseary for direct playback on set, if you dont have one then a laptop with Mlvrawviewer for vanilla MLV’s or FastCinemaDnG for lossless mlv real-time playback. Also MLV app is good for a checkup on files, but it does not have real-time playback.

About DNG look, it is all about interpretation in your preferred NLE/grading sofware. I recommend Davinci Resolve.

Typing on phone so this is getting tediously long, let me know if you have more questions.
"An external recorder is necesseary for direct playback on set"
Just a small question from a swedish filmmaker: Is there a plain recorder without screen to be found within a reasonable price range?

as i was using magic lantern for first time, i ddnt go very deep into settings.
i shoot in MLV raw full hd with 23.97 frames.
no dual iso or anything.
trans coding the footage was heck of a job. The transcoding app i used was crashing now and then.

graded in davinci resolve.

Use the new MLV app!

Is it possible to use DualIso in conjunction with the experimental set-up with 45 fps and 1920x1080? How do you go about? How do you set it all up in the camera?

Yes you can use MLVApp for dual iso. Processing is 20bit (attaching low and high iso).

What ISO is best to use? And - is it of equal result to make adjustments in the MLV app as doing it later as exported CinemaDNG uncompressed in Photoshop?
20bit!!! Any other camera on the market that can do this...?

just a notice on the timeline-percentage counting down while processing MLV files: it is sticky!!! meaning when changing to another program in mac High Sierra it does not go away - it is permanent whatever other program you decide to work with (intentional?)

Can I use the MLV app to process Dual Iso videos?
If not what to use?  (High Sierra)

MLVApp should run on any computer which is able to run Windows 7 (or newer) and OSX 10.8 (or newer). For Linux: our AppImage should run on Ubuntu 14.04 LTS or newer (maybe others too which use similar versions of packages). If you compile yourself it could run on many different distros (you just need ffmpeg and >=Qt5.6).
Hardware plays nearly no role: no GPU needed for example. So it should run also on very old computers and notebooks.

I am planning (if possible...) to use a small single board computer, an Odroid-xu4 or similar while travelling. To be able to convert the MLV files to H264 too see the actual movements in realtime of the videoclips at the place of filming. Without having to bother with a big laptop or such....

...or perhaps you have a better portable solution?!

What are the minimum hardware (and software? Linux?) requirements for running the MLV app converting MLV files to H 264 files?

Thank you very much masc and Danne  :D :D :D

Sure - this was the main idea of the app. But, what do you do in Photoshop, if you color correct in MLVApp? If you like the look more than from Adobes RAW processor, use it! AVI has only 8 or 10 bits bitdepth. ProRes 4444 (AVFoundation on OSX) has 12bit. TIFF would be absolutely uncompressed and really huge.

I want to do all sorts of filtering - parts or whole with many layers and even do special constructs. all in all work with every video just like with a still photograph. The exact look from the file coming out of the MLV app is not that important BUT what is is to have as much inrformation as possible in the file to work with

I think I will try CinemaDNG with the possibility of converting to TIFF and with a proxy of perhaps ProRes4444...

Is the TIFF files from the MLV app the same as going via CinemaDNG to TIFF? If so then I can use the MLV instead of CinemaDNG....

How about ProRes RAW?

= RAW = CinemaDNG.

...but the MVL app almost look like a RAW processing app! Perhaps it gives enough of the videos as to be compared to a RAW processor?
And if so is AVI the best output to save the quality of the files? Or?

No you don't get the same colour. But this is no question of bitdepth. MLVApp exports 16bit TIFF.
If you export TIFF directly you export processed data. If you export cDNG, you export RAW data. The RAW data has to be processed somewhere else. I bet it won't be processed in the exact same way as MLVApp does. So the colour will be different.
What would you recommend - to make the adjustments in the MLV app as a Raw processor and export as processed Tiffs OR export as CinemaDNGs and process in a Raw processor like Photoshop?

I want to work with my videos in Photoshop therefore the CinemaDNGs...
Do you know any other way of getting the videos from MLV to photoshop as untouched as possible?

(I am an artist in photography for soon 40 years and now I going into film! My favourite tool since 1990 is Photoshop and I want to be able to continue with it if possible. I found out that I could import Avi´s and Tiff streams among others into it but I want to know which sort of file is the best one and got the most info to get me the maximum freedom in working with the films)

MLV > CinemaDNG > TIFF  versus  MLV > TIFF directly

Do I get the same 14 bits of colour when I export files from the MLV app first as CinemaDNG and then convert them to 16 bit TIFF files as I would get if I export them directly into a TIFF stream from the MLV app?
Someone said that a TIFF stream directly from the MLV app only retains 8 to 10 bits of colour....

Continous: "1920x1080 @ 45p"
NOT 48p.

Tried this but stopped after 4 seconds...

Optimize for?
Special set-ups for avoiding crashes?

How do I set up my mk III to succeed in filming with 48 fps continuos at 1920x1080 without a break (AND what not to set up...) - I tried everything 😟
Please give me a recipe how and where to fill in what in the Magic Lantern menus...
I will be forever grateful!!!

If you work in Photoshop, chose cDNG, this is unprocessed (or at least lossless) and has full raw info availlable.

What is the difference between uncompressed and lossless cDNG and what would you recommend me to continue with into Photoshop where I will work with video as with my former art images?

Really strange...

I downloaded your MacBeth MLV and exported as DNGs w/o a problem, be it lossless or uncompressed. Both are exported fine!

When exported to another harddrive it worked....

Yes, for example. You can post the link here, or you send it to me via PM.
