Raw Video / Re: 550D/T2i raw video recording port official thread
« on: October 27, 2013, 12:18:48 AM »
Works perfectly for me

Rewind, sorry to bother you.

So, dual ISO...then, do you use ETTR? Or no?
And which application do you use after that? I know that a1ex recently created the cr2hdr_exp.exe. Or were you having success with the "older" cr2hdr.exe?

Just curious if I am missing a step here, or if I am just using the wrong programs/approach. Thanks in advance.

We are shooting dual ISO on 550D's for about a couple of months.
http://www.magiclantern.fm/forum/index.php?topic=5582.msg69853#msg69853

Rewind, have we been successful? Last time I tried this a month ago, I couldnt get the output to convert. Every time I recorded something and tried to convert it, I got the message "this is not interlaced ISO" or something along those lines.

I'd be interested in testing it again.

Hello All,

Has anyone being using Transcend Card?
http://www.flipkart.com/item/ACCCZ4FFCENSFKG2

32GB SDHC 20MBps Class 10

Is it suitable for RAW?

Please reply.

Cheers,
Prabhath MP

It should be fine. I wouldnt get too caught up on brand names or write speeds. As Rewind mentioned, as long as it is around or faster than 20mbps, you are fine. Definitely stick with the class 10 cards though.

Yeah that got it working.  Can you add a command line option for the user to select how many instances to run at any one time.  And then when a bunch of CR2s are dropped on it, it's spawns all those instances?

I tried adding a heap of compiler options (-msse etc etc), and it made no difference to the processing time :(


If I can ask, how did you get it working? Did you just download a1ex's experimental upload (seen above) again? (which I assume has been updated)

I read the first page and downloaded MK11174's latest build with DUAL ISO. Was just wondering if that one works, if it's stable and how long and good clips you get? And if it's just to install it like the regular ML build without RAW? Is there any installation guide?
Would appreciate if people could say which build they use for their videos and so on :)

The build mentioned in the video is a little old, but you can download the newest one from the first post as mentioned.

I guess if you getting bad results, it might just be to much of a dynamic range that your trying to achieve. Only time I ever had an issue.

I wonder if this is MY issue. I've tried this at night within my house and the shadows may have been way too dark vs the light in the scene. Now that you mention it, I thought I read somewhere that someone had a similar issue with TOO much dynamic range.

Hmmm....may have to adjust my testing. Thanks for the reply.

mk11174,

What is your workflow for the 550D for the dual ISO?
I saw the posts over at the dual ISO post and saw that the cr2hdr was just updated yesterday.
However, was that just to fix an issue with the 600D? Have you had success with the t2i? Are you just recording the video, converting to DNG, and then dragging into the application (cr2...)?

Any insight would be helpful. We aren't getting consistent results.

@telecastDaveRI: For our "low-information" readers and noobs, we should probably avoid calling Dual-ISO footage "interlaced", although I certainly know what you mean. If you are shooting Dual-ISO correctly (I mean, maybe not optimally, but getting footage where alternating lines have different ISO values), the individual frames look "interlaced", except that the two sets of lines are of course not separated in time by a half a frame, like NTSC or PAL interlaced footage. On the other hand, you can't "de-interlace" this footage in After Effects, because it isn't "interlaced", it's just Dual-ISO, which is a completely different concept. What you are seeing as successfully "de-interlaced" footage in AE is just a result which eliminates or blends alternating lines to make the individual frames look "smooth". But what a1ex does in his dual-iso software (originally an updated version of raw2dng.exe, but recently he is suggesting using cr2hdr.exe) is a fairly complicated mix of interpolation, estimation, prediction,etc., which attempts to combine the best pixels from the alternating-line footage in order to give you an image with an increased dynamic range. I can't stress it enough: though the dual-iso footage looks "interlaced", it is NOT interlaced in the true sense of the word. For what it's worth, I still can't figure out how to do the second step of a1ex's suggested dual-iso video workflow, that is, to "drag-and-drop" the .dng files on top of the cr2hdr.exe executable. When I do that, nothing seems to happen. When I open a command line, navigate to the location of cr2hdr.exe, and run it with a command like "cr2hdr.exe thingy.dng", where "thingy.dng" is one frame from some dual-iso footage, then sometimes this seems to work and produce a frame which no longer looks, um..."interlaced". But sometimes not, and this is obviously not a workable solution if your dual-iso footage contains hundreds or thousands of frames.

I guess we're both waiting for someone to chime in who has this working reliably (on a PC, I might add). It's fun to play with but I wouldn't want to use dual-iso unless I had a situation where I had to, as the resulting aliasing issues make it hard for me to accept the resulting images, noise-free (or close to it) though they may be. Cheers!

NedB, you are absolutely right with everything that you are saying. Yes, all After Effects is doing is blurring the "lines" a  little and that's not really accomplishing anything. As far as the problem that you have with the nothing happening, do you have the program and all the dngs in the same folder? I have been able to do it every time, but for me, nothing appears to happen after I run the program and review the footage. If you havent been keeping the program and files in the same folder, and try that soon -  and it works, I'd like to see how well you make out on any future tests.

@telecastDaveRI: Would you mind telling us exactly what ML you're using and also what cr2hdr.exe and raw2dng.exe (links if you have them)? I had an experience similar to yours where I thought it didn't work and then all of a sudden I thought, "Oh, yes it did". So I put dual-iso aside for a few days, hoping it would become clear what the issue was. If you'd tell us exactly how you got your results, I'll try to reproduce and then report back. Thanks in advance and cheers!

Edit: Oh, and if you don't mind, what dual-iso settings/resolution/etc. Just to eliminate other causes of "failure"...

I tried both the cr2hdr.exe and cr2hdr_exp.exe (the former is in the first post on the "dual ISO- massive..." forum.) and the raw2dng listed under this forum, and now I am getting interlaced footage, but no matter what, the cd2hdr doesnt recognize it as interlaced and nothing changes. I had my settings at 100/1600 and 1200 frame size at a 3:1 aspect ratio, just to test. The other night, I took some footage and I was successful, but I cant recreate it. Anyone else having success with dual iso and raw? I'm going to keep testing today.

EDIT: popping the footage in After Effects and de-interlacing there works just fine. Still curious if I am missing something.

Rewind,

What module did you add so that it would crop everything but the area that was being recorded? (everything else was black)
That was useful :)

Was that you that compiled the release that included that?

hello guys, I'll be out for the day, but now I am getting interlaced footage no problem. I just did a quick test before I am walking out the door.
I choose alternate lines (it's a setting under dual iso...I dont have my camera in front of me)
but now I am having issues with it converting!! I dropped the raw into raw2dng, and then from there I moved it over to the the cr2hdr_exp.exe and nothing happened! (a DOS window flashed, and disappeared)

When I get home and play with it some more I will provide the links and any success I have.

EDIT: to keep things organized, I had it in a folder within a folder. I then moved the dngs to the root folder and they converted!! The thing is....now, they are no longer interlaced. What I personally would like to test is if the ISO is actually having an impact or if I am just interlacing and deinterlacing "normal" raw footage :)

Any one successfully shots dual iso video and then post processing OK? mine case after download mk11174 cr2hdr and raw2dng file, dual iso raw video file still interlaced after using raw2dng (drag and drop method)

any methods that work for our beloved 550D? (i'm try to use alex method: using his raw2dng first and then cr2hdr but bad result in the end)

I'm having a different issue. What settings are you using. My issue isnt a matter of they not becoming....er....un-interlaced. I just keep getting a messaged that the footage doesnt appear to be interlaced, and after reviewing it....it isn't. I'm shooting raw video and choosing the dual ISO option. I must be overlooking something.

EDIT: despite what it says, it's working now! I reviewed the image before and after and it definitely went from interlaced to a "useable" video/image sequence! awesome stuff!

I saw this mentioned on this forum before and I just did a search for it, and cannot locate anything on it.
(It's possible that the posts were screenshots and that is why search cannot locate them).

I shot some raw video tonight using the dual ISO and then after creating seperate DNG files for each of them, and then dragging them into the newest release of Cr2hdr, I get a message that it "doesn't look like interlaced ISO" as it reviews each file.

Ideas? I thought I may have read somewhere it was because the scene could have been too dark.

Gentlemen,

Can I ask what the settings you guys are using for the Dual ISO for RAW are. I did a couple tests yesterday.
Dragged them to the raw2dng and then cr2hdr application afterwards, and it mentioned in the DOS window that the images were not interlaced. And then when reviewing the footage, nothing appeared to be anything out of the ordinary from shooting "normal" raw video.

I tried at ISO 400 and the dual ISO set at 3200. Am I missing a setting? I review the post by a1ex and I believe I am doing everything correctly.

Thoughts? Suggestions? Insults? :)

mk11174 - a1ex just posted a new file (I believe) "I've uploaded it to cr2hdr_exp.exe," on post 760 over on the Dual ISO post. I know this is the raw post, but since it has been brought up, I'm mentioning it again.

I know I have the ability to compile it myself, but I haven't been able to yet. When you have a moment, can you include the new file? from what I understand, it handles moire/aliasing better (which I guess is more obvious with the dual iso feature)

It might be just you :)
The color shouldn't matter because raw is raw. Nothing is baked in like with the h264 compression and any picture style that you are using.

In other words, you can make them look identical color-wise. In fact, you probably could have adjusted the exposture on the raw on that video - it was a little dark.

Check out my video - you can definitively see the difference. especially on the fishbowl.

How would we accomplish that?
It is as simple as downloading the 50D tragic lantern zip and then maybe sym file to the 550D one?
Or would it still have to be compiled in some form or fashion?

Would a 7D make more sense?
(I'm unsure if you were just making a point with the 50D as it had less capabilities).
I'd almost be willing to test...it's just a matter of determining how :)

Hey Guys

I heard about your firmware a few weeks ago and thought I would try it out.

To me good colour accuracy and no compression is more important to me than resolution.

I work in visual effects so the thought of dealing with a stair stepped 8 bit moving image makes me shudder.

Anyway I put up a couple of tech tests stopping the exposure up and down with the firmware you have put out there:


My Cat, with fur detail which would get lost in compression


A bowl of fruit


It shows the dynamic range of the image, the compression artifacts are questionable, because you are looking at footage that is compressed out of Nuke and then compressed again in Vimeo.

Everything seems to work as it says on the tin.

What is a decent card to be using to get the maximum throughput. I bought a Class 10 Ultra SanDisk 30Mb/s Card but it scarely does about 8Mb/s in the camera.

Anyway hello from Adelaide, South Australia, I hope you are having a great day.

Sam


Sam, your card should be fine. That is strange that you are only getting 8Mb/s in the camera. I have a pny (I believe) 35Mb/s card from some retail chain store (best buy, walmart, I forget...) and it usually getting around 19.5Mb/s. (by the way, don't expect much more than that. If you do switch brands, you don't necessarily have to get anything that is extremely fast as the camera can't output that fast. I assume you have the 550d.

I guess it depends if the nightly builds come with ettr, pic_view and file_man which the versions in here do come with, maybe these are important to some people, I have not used a nightly build in awhile so I am not sure what they included, I always build myself. If everyone is happy then I would say they are not needed. I have not noticed any new updates in a long time, I hope the developers have not given up on the ML developing.

I agree! I know that I've seen the developers on other forums, so I know their time is pretty taken up by multiple platforms, but I would love to see if we could somehow allocate enough memory to at least get 1280 by 720 at 24fps. I was able to get that resolution at 12fps the other day with Rewind's build. So close I can almost taste it :)

Rewind, thanks for the compile! So are you basically just searching the other forums (600d, Mark II) and locating great features and compiling them?

I need to watch mk11174's video on that again so I can assist :)

I'm using raw2dng.exe on Windows 7. It works great, EXCEPT when a file 'cuts out' during recording (I guess ran out of memory). Is this normal?

The .RAW files are still >100mb so there is data there - is there any way to get that data out?

There's no way I know to recover these. However, make sure your camera is not set to power off after maybe 30 seconds or so. I experienced that early on and then realized it only powered off after I was successful and a minute had passed. I just assumed it was too much for the camera to handle....but then I realized that I had the camera to power down the display after a minute.

You need to use a fisheye lens ;)

There is another way though. Find the menu item that says "raw video" and switch it to "off".

Or, even better, start the camera without Magic Lantern. It's not targeted at beginners.

Best response ever   :)
