Have a 95 mb/s card, setting the resolution to 640x480 (not the RAW video resolution though) always fixes it.

Shooting a shortfilm in RAW this week has been fantastic. Most of the shots do not need to be particularly long, so there isn't much worry about frame count and I've been shooting above 720p in 2.39:1 aspect ratio, which is perfect. RAW is definitely looking better than my H.264 shots which I've been using for longer shots. I'm actually preparing less for each shot because I don't need to worry about the exposure or HDR. RAW has made my film look like film, instead of DSLR video.

Why I love shooting RAW video:

640x480, 1080P both modes are all the same raw input. Just 30fps needs to be overridden.

Crop is slightly different raw, zoom is bigger raw. 720p is squished raw.

You can use any mode you want, with GD off shouldn't get any pink frames.
I still get pink frames with GD off in resolutions about 1280w. Setting the camera to 640x480 mode with seemed to fix it though.

Is 640x480 mode supposed to be better for RAW video? If it's better for performance is it still worse in resolution?

I seem to get more frames and less magneta.

That's what's so weird, I have a Sandisk Ultra 16GB class 10 which advertises 30MB/s read/write speed. But the benchmark says different.
Same, I only got 12 max. That's why I upgraded to a 95 mb/s card.
Raw Video / Recording uncompressed JPGs?

Maybe this is a silly question but if we can shoot uncompressed RAW shouldn't it be possible to shoot uncompressed JPG video? Wouldn't this allow for a lot more FPS and greater resolutions?

Got a 95 mb/s card today which makes this pretty awesome. I can get at least 440 frames/18s from 1216x512 now which is very usable for film making. No magneta frames for me.

There's something really unique and exciting about this - not being able to properly see what you've shot, or hearing actors' performances, until you process it on the computer. So watching it later is more of a surprise. It reminds me of working with film in that way.

EDIT: Actually have some magneta in 1728w.
Some comparisons I did shooting RAW on 600D:




EDIT: Nevermind.

Same settings? So you didn't changed the focal length and simply croped the H.264 to match the raw image? If that's true, your comparison is completely useless. To compare H.264 and raw you have to count in the new crop factor you get with raw video! See here:

Width | Cropfactor | Multiple of H.264 crop

1734 = 1.60 | 1
1280 = 2.17 | 1.36
960 = 2.89 | 1.81
720 = 3.85 | 2.41

So if you shoot a video in 1920 X 1080 H.264 at 55mm and you want to compare it with a 960 X 540 raw video you have to change the focal length to 30mm (55 / 1.81 = 30).

Edit: Damn. No I tried to answer that questions and totally forgot what I wanted to ask :D

@1%: Since raw is a dead end on the 600D (Even with 8-bit compression we couldn't record higher than 1280 X 720 :(), what's about recording YUV 422? Is anybody still working on that for the low speed cameras?

I mean, lv_rec still had the option to record YUV 422 "video". It was just to early to be good ... But now, wouldn't it be a nice to make a yuv_rec module for 600D/550D/60D(/6D)?
Uh, I don't know about focal length but neither of them were cropped at all. And the RAW video was 1136x640.

Another comparison of some grass (only the RAW was cropped here), with the lower resolution RAW video as the clear winner:



EDIT: And another with some tree foliage. RAW is definitely better for nature.

I shoot Raw with my 8/16 GB SanDisk Ultra 30MB/s...
Nothing more than 3 seconds still at 960*540...
Doing the ML test and results that it write at 8MB/s...
How it's possible?
Same. Cannot get mine to go over 12 mb/s.

Wow, and I thought I had a good card. Didn't know it was this much of a rip-off before. My Sandisk card is averaging 10 mb/s when it should be 3x that. And yeah, I hope they would just use the mb/s.

Just did another RAW vs. H.264 comparison, and this is the biggest difference I've seen between the two yet. Exact same lighting conditions and exact same camera settings, but the RAW version is at least 10x better.

You can tell the difference even more in motion, because even though the ISO is only at 120 the H.264's blurred out background looks just blocky and bad because of the compression. While the RAW version is smooth and natural looking. This is definitely worth getting a new SD Card for.

20 frames dropping after about 50 frames on 960x540, even frames dropping at a pathetic 322p. I'm using a SanDisk 64GB 30 mb/s, but it's recording 12 mb/s. I've seen other people doing better. So the card matters?

I've tried lower than that and still can't get continuous. It can drop 20 frames at a time.

Quick comparison of H.264 and RAW. Notice the details on the blue towel and wooden block.

Ah thanks. Still skipping a ton of frames but at least I can see what I'm shooting.

Noob to this whole thing, installed Magic Lantern and RAW to my camera for the first time today.

Highest resolution I've recorded at so far is 1440x602 (2.39:1) which looks fantastic. Everything's normal except when I start recording, I can't see anything that's filming, it just freezes on the screen. And I can't seem to have any image size that doesn't start majorly skipping multiple frames after 5 seconds. My card is 30 mbps, and I didn't think that was bad since it will only do 21 mbps anyway. Are either of these problems normal with the T3i?
