Ok, could you say what settings you used? :-) Did you shoot 720P h264 or 1080P, we know 720P h264 is pretty shocking? What raw resolution did you shoot at and upscale to 720P? Did you shoot 24fps or lower to get higher resolution?

Had you compared 1080P h264 scaled to 720P vs raw upscaled to 720P?

There's a big difference in detail in your example but just how much is that atributed to raw versus badly captured h264, there's a difference in contrast and saturation between the two as well which can affect perception,  personally on the fence at the moment having tested 550D at 960x408 24fps feel like sticking to 1080P h264. :-)

Windows exe of raw2dng works fine with Wine.

You don't explain how you're trying to use it but here's a test:

If you put a copy of the raw2dng.exe into the same folder as the RAW files, then open a terminal, change directory, ie: cd to the folder with the RAWs and then type wine ./raw2dng.exe M000001.RAW or whatever your RAW's called then it should work for you.

If not post your error message.

Quick test shot (1200x400 23.976)
SanDisk Extreme Pro 16GB 95Mb/s

xaint, looks good but was that shot in Photo mode? The metadata for the .mp4 says 1920x640 at 30fps? mediainfo and VLC concurr.

Regarding photo mode, I seem to get more resolution, without failing, but guess something else is going on. I have fps override on at 24.000 exact and manual lens.

You can only choose resolutions multiple of 64x32 or 128x16, for speed reasons. See http://www.magiclantern.fm/forum/index.php?topic=5839.msg42968#msg42968

I can remove this restriction and keep the write speeds, but this requires changing the file format and the converter.

Thanks, I thought there must be a technical reason, hadn't considered it was a mod16 thing, even though well aware of it and that the 550D is 1920x1088.  :-[

With this latest build, not noticed it before, maybe it was there but resolution and aspect ratio don't seem to work correctly, if you set resolution and then aspect ratio, resolution changes but it doesn't change to suit dialed in aspect ratio but instead gives in brackets (almost whatever:1) which is different to aspect ratio chosen.??

So default is 1024x576 aspect ratio 16:9 both aspect ratio chosen and AR in brackets match, but then change AR to 2.39:1 in the raw menu, resolution changes to 1024x432 and in brackets 1024x432 (2.37:1), change AR in menu to 2.35:1, resolution changes to 1024x448 in brackets below 1024x448 (almost 2.29:1)

Confused.
#81
speed improvement?? What's that? Greater than 24fps? :-)

exfat is about greater than 4GB files for ML anyways, also other features, although I maybe wrong. :-)
#82
exfat works fine with 550d, just format the card with eoscard utility, make it bootable, install stable ML through eoscard if you wish then substitute files and folders with MK11147 build.

**EDIT**

Posted sametime as NedB. :-)

There's another version of the LCDV3, the V2 which comes with a metal frame that sticks on with double sided sticky tape, available through amazon: http://www.amazon.com/CowboyStudio-CA0602-Viewfinder-Digital-Cameras/dp/B005EM6G7U/ref=sr_1_sc_3?ie=UTF8&qid=1369942550&sr=8-3-spell&keywords=lcdvr

Been using one for years now with sticky taped frame over a clear LCD screen protector, frames never become detached. :-) Not liked the screw on bracket version because of quick release plate I use.

Used a Hoodman loupe before that, biggest waste of cash ever, horrible thing, feels like tunnel vision, no magnification, the diopter idea might be great if someone needs spectacles but having to focus the diopter to get the LCD screen in focus and then focus the lens is just a PITA, move your eye a little left or right in the eye piece and the diopter focus changes and you get CA and a $18 dollar elastic band to hold it on meh!

Post-processing Workflow / Re: DSLR Color Space
May 30, 2013, 09:27:25 PM
As romeus says sRGB and rec709 share same color primaries, it doesn't matter whether rec709 or sRGB in that regard, as T2i will use those primaries.

T2i does however use BT601 color matrix. AE & Premiere post CS5 both interpret this correctly, so does FCPx.

Canon DSLR's encode h264 over full 8bit levels 0 - 255, it's JPEG JFIF specification hence BT601 color matrix, rec709 primaries.

The h264 stream has a VUI Option metadata flag 'fullrange' set to on, so as soon as any decent h264 codec implementation reads the flag including via Premiere CS5 onwards or FCPx the full normailzed 8bit levels are squeezed into rec709 'restricted' range 16 - 235 luma, 16 - 240 chroma.

Gamma difference between rec709 and sRGB is marginal but suggest sRGB is more suitable due to JPEG / JFIF spec.

Premiere , After Effects interpret as sRGB, you'd have to switch the fullrange flag off to get rec709 interpretation and then due to the full range levels RGB channels would get clipped in the color space conversion.

Bottom line suggest treating Canon T2i h264 as sRGB / JPEG regardless including through Nuke.

Someone mentioned line skipping. Would it be possible to take use just the center of the sensor to avoid line skipping? Just like GH2 does in EX. Tele Conv. mode ?

It was me mention line skip vs crop, photo mode vs video mode. I'd read a how to by RenatoPhoto on how to do a crop mode using the 5D3 but can't find the post now.

**EDIT** Found It.

The beauty of this video is that there is ZERO loss of detail when compared to a photo taken a full resolution.  Of course the photo covers the entire size of the sensor 5760x3840 pix while the video is just a small portion of the sensor in my case I am generating a video of 1920x1080 pix.   There is no down-sampling of the sensor so the image is a 1:1 crop.

Since we are using 1920 pix out of the 5760 pix (width) the zoom factor is 5760/1920 = 3X.

For anyone wondering about the white rectangle and constant bitrate, these features are all enabled in the later release I posted with EttR and Crop in it, http://www.magiclantern.fm/forum/index.php?topic=5582.msg40875#msg40875  I see the Raw rectangle as I record Raw, if this is the rectangle you mean, maybe you need to clear your ML config file, it is loaded and works. Let me know if this is the one your talking about.

I think a little bit of misunderstanding here between the three of us. :-)

The white rectangle in raw record is the feature in question, but when testing what to switch on and off during recording to get a continuous 960x408 I found 'Clear Overlays' when recording solved drop outs, so I'd use focus peaking, zebras, white rectangle and raw histogram to compose and expose then when hitting record overlays were cleared, but of coarse this removed the white rectangle. :-( 

So to be able to switch off focus peaking, zebras and histogram when hitting record but leave white rectangle on might hopefully still prevent drop outs but give a framing target, currently I just drew a rectangle on a clear LCD protector with an indelible ink pen :-)

QuoteI also get 960x408 at 24fps regardless if I turn global draw and any other feature off, so you should be able to keep everything on that is enabled for the release. Hack mode does seem to stop the skipping with 960x408, it always skips after 72 frames 1st try but the 2nd and next tries till I reboot cam all are no skip. I use 45 MB/s sandisk extreme and yes, only get max 20-21 mb/s cause that is as fast as the cameras controller will record no matter how fast your card is.

I tried leaving overlays on and got dropped frames with a 95MB/s card (21.5MB/s controller max)

Regarding setting raw resolution in the menu it would be really good to set a default to 960x408 but it doesn't save in config, so every shot when turning cam back on we have to switch the resolution back from 1754x??? whatever it is, even though the 550D just isn't capable of that resolution anyway.

Obviously I'm not complaining, this is alpha experimental and I'm very grateful to you for the builds, we all are but would be great to smooth out some of the fiddling in camera.

On a positive, I too looking forward to trying out the tracking (panning) feature. :-)

I added to the confusion in an earlier post about photo mode vs video mode, CFP put me straight, bottom line no point using photo mode unless on a 5D MKIII. http://www.magiclantern.fm/forum/index.php?topic=5494.375

Quote from: CFP on May 29, 2013, 03:42:56 PM
It doesn't make any difference in picture quality and it should make no difference in performance. But in photo mode you can't set ISO, aperture and shutter speed manually. Sure, you can change the numbers but the actual aperture doesn't move if you change the number on the display.

So: For manual exposure control, record in Movie Mode.

raw2dng.exe is a command line tool? So you could fire up a terminal with Run cmd from your Windows start menu, change directory to your raws and raw2dng exe with cd whatever then type raw2dng M000000.RAW, hit return and that should do it. Otherwise could try one of the batching tools from the Post Pro thread?

I managed to get my camera to crash shooting RAW. Just dropped battery and I was good to go. I noticed that I have to setup the RAW feature in video shoot mode, then shoot in photo mode. At the end of a recording using 1:1 ratio the camera hung and created a error file. I guess I should pass this on, but I'm not sure if the core Devs are interested at this early time of 550D implementation.

I gather there is no way to get full FOV due to memory restrictions. So there are no additional line skips available? Grateful that there are at least an overlayed shooting box :)

3point, use video mode for raw, forget photo mode, it doesn't offer 1:1 vs line skipped, I was mistaken, only 5DIII has that option so far I think.

I'm getting continuous using 960x540 at 2.35:1 (960x408) with a Sandisk Extreme Pro 95MB/s although max is about 21.5MB/s through SD controller. I have Global Draw on, the scopes, peaking and zebras then clear overlays automatically when recording and drew a small box on an LCD sticky screen protector for the white rectangle to help framing.

Yeah for sure, a build that could keep the framing box on but all other stuff off when recording and not have to keep navigating through resolution and aspect ratio every time switch camera back on, being able to set a default res and ar would be useful. :-)

I've been playing around with ML raw on my 600D, just thought I would share my speed tests if it helps the ML team:

SanDisk Extreme Pro 95MB/s 32GB

Write speed------20.7MB/s
Read  speed------21.2MB/s
Write speed------19.1MB/s
Read  speed------20.9MB/s
Write speed------20.7MB/s
Read  speed------21.2MB/s
Write speed------19.4MB/s
Read  speed------21.0MB/s
Write speed------21.1MB/s
Read  speed------21.3MB/s

LearningDSLRVideo.com

Yes, I get 21.5MB/s max from that card also, it's enough for 960x540 at 2.35:1 (960x408) without dropped frames. But the limitation is the SD controller in the T2i / T3i etc.

Ok, good to know and to be aware of the photo mode restrictions. I've always shot fully manual in every respect prior to testing the raw features. Thanks again.

There's a feature in the newest Magic Lantern builds that allows you to change the picture quality for photos inside the Magic Lantern menu.
Usually this is only possible in Canon menu. You know, that are the settings like "L" (For Large JPEGs) or "RAW+L" (For Large JPEGs and Canon raw pictures).
And since the Rebel line had only one size for raw pictures, ML added two more sizes: MRAW and SRAW (Medium and Small). They don't work properly but they affect the size of the buffer. And that's the important thing: The normal size of the buffer is 68 Megabyte. With MRAW it's only 36 Megabyte but with SRAW it becomes 96 Megabyte. And with a bigger buffer you can record more frames, even in higher resolutions.

SRAW has nothing to do with crop modes. And it doesn't affect the image quality of the raw videos. It only increases the size of the buffer.

But when SRAW doesn't work on your cameras then 1% probably was right when he said that the 550D is actually the worst camera for raw video. But don't worry, 600D is the second worst :P

And keep in mind that when shooting in Canon's 720p mode you'll get even more aliasing than in 1080p or 480p mode since it has even more line skipping. It's only usefull if you want to get as much width as possible to keep the crop factor small.

CFP thanks for such a detailed reply. Regarding the buffer size, if buffer is 'Shoot malloc total' yes I see 68MB. Cheers for the explanation.

A quick question I've asked on the 550d thread but no answer, should we be shooting in video mode or photo mode with 550D and 600d cams, does it make any difference? Freeing memory well, I'm limited to 21.5MB/s and achieving no pink frames or drops in 1000's of frames captured, so query is more about 'quality of feed' line skipped or crop, apart from the obvious resolution restriction.

Currently I'm having great success recording 960x408 2.35:1 no drops to exFAT in either Photo (set to RAW)  or Video (set to 1920x1080 24fps) mode.

What I'm getting at is the 16GB of raw files I shot the other day in video mode line skipped lower quality than I would have achieved in photo mode?

Sorry if it's a dumb question but this site's like a freaking rabbit warren of threads, plenty of how to build this and that for raw but not so much how to actually use it. :-)
#93
Could someone clarify then this sRAW, is this the difference between line skipped video mode vs 1:1 crop photo mode?
#94
With MK11174's builds has anyone got 'Seperate WAV' working? I've switched it on in the audio menu rather than using 'Beep' although beep is useful to signal start and end of recording as I clear overlays on record but have no WAVs on the SD card.

Is Seperate WAV for recording to an external audio recorder? Anyone using an external audio recorder in any way with these raw builds?

This raw is kicking H.264's ass so hard it's almost funny. I just put together a little clip at 960x408 and I'd almost venture to say it appears sharper than the 1080 H.264.... I'll upload tomorrow, it looks very cool (with very little effort).

Is this using the Photo mode ie: no line skipping or 1920x1080 video mode with line skipping?

http://www.magiclantern.fm/forum/index.php?topic=5441.0

I've only tried it out so far with the later, should I be using Photo mode 1:1 crop, is it even available for 550D? Haven't had chance to try yet.  I'm using MK11147's builds. Cheers.

**EDIT**

Nevermind, sorted, been so long since I used any mode other than video I'd forgotten how to use Livemode in 'M' or any other photo shooting mode. Photo modes give waaaaaay better output than video modes. 1:1 crop vs line skipped.
#96
Dcraw will export 16bit Tiffs, you have control over the raw development to start with plus choice of colorspace such as Prophoto, XYZ, AdobeRGB, sRGB or undefined RGB, you have cotrol over WB and gamma, so if you don't have access to raw handling in an editing / grading app 16bit Tiff is one route baking in WB etc but retaining some space (16bit per channel levels) for 'grading'.

Big problem is at 1080P that's 12.8mb per frame. :-)
#97
mk11174, thanks for latest build, I got to apologize  :-[ , the 'cropmarks' was wrong term, I meant the white rectangle that's on screen showing the 'crop' area for the 960x540 2.35:1, it disappears with 'Clear Overlays', sorry and thanks again.
#98
Hi 3point, sorry yes should have said, that's 'continuous', 500 - 600 frames or more before I stop rather than camera stopping. :-)

Processing wise, if I go from dng's then RAWTherapee as Darktable crashes with the dng's, need to mention it to the DT devs or have been using dcraw directly to 16bit Tifs various colorspaces, which DT then handles no problem.

Then I think possibly image sequences into Blender, edit and frameserve out through Avisynth for temporal noise reduction, luma sharpening, upscaling and encoding via x264. Or proxys via kdenlive to intermediate -> Avisynth -> x264.
#99
@mk11174, finally having chance to try your 550d build out, 960x540 2.35:1 ie: 960:408 is about the best I can get, Sandisk Extreme Pro 95MB/s or 45MB/s makes no difference as discussed previously, which is fine. :-) Doing the buffer test gave me no more than 21.8 MB/s at it's occasional best.

But I have a couple queries.

1. I'm using a dedicated SD card for raw video, 960:408 is the largest resolution, aspect ratio is ok so it would be great not to have to keep going in and setting 'RAW video' to ON, then choosing resolution, then choosing Aspect Ratio whenever I switch the camera off and on between shots.

2. It's great to have the overlays, raw histogram, focus peaking and crop marks then switch to clear overlays for recording. But is there any chance of keeping crop marks on, trying to judge where the letterbox is for keeping framing is difficult. :-)

Going to try your Auto ETTR build next, thanks for your continued work for the 550d owners. :-)

#100
mk11174, thanks for the latest build, haven't had chance to install or use it yet, need to get some more SD media, but is AutoETTR available?

Regarding SD media, is class 10 (New Faster Version) 45MB/s 32GB's Sandisk EXTREMES sufficient for raw video capture on 550D, so reasonable price. :-)

I've been using UHS Class 1 90MB/s on a 550D for h264 but now it's known how slow the SD port is what's the point?
