In movie?
Yes. It was in 1080 Movie Mode.

Does this also happen on the other cameras? Or is it just (my) 600D?

apefos

about RAW in 600D:

the "width x height" values are fixed to choose from a table of values or can we type any value we want?

would it be possible to try 960 x 520?

14 bits / 8 bits = 1,75

960 x 520 = 499200 x 24fps = 11980800 x 1,75 = 20966400 (under the 21MB/s limit)

I can shoot continously in 960 X 540 at 24 frames per second. An even lower resolution should be no problem.

JohnBarlow

If that is so I wonder if we can sample alternate rows and columns to preserve FOV?

(OK because of mosaic alternate double rows and columns)

This would be better than a quarter crop; yes?

but the 960x540 is reported to have magenta frames, this is why i suggested 960x520, to try to avoid drop frames and magenta frames.

maybe 940 x 530 can work also

I am just trying to suggest some "nearest quarter full hd" options close to 1,777 aspect ratio and  under 21MB/s to make the upscaling to 1280x720 or 1920x1080 the best possible.

Would have been easy but now height is from aspect ratio... so what aspect would that be I guess?

Also just tried switching expo with the shutter and no problems.

apefos

Hi 1%

the idea is to get the biggest resolution "width x height" in 16:9 aspect ratio (1.77777x)

best option would be 960 x 540, but people are reporting magenta frames, so...

something like 942 x 530 could work good

942 x 530 = 499200 x 24 = 11982240 x 1,75 = 20968920 (under 21MB/s)

or 940 x 528

940 x 528 = 496320 x 24 = 11911680 x 1,75 = 20845440 (under 21MB/s)

So you want to add 942 width and 940 width?

Those don't work.. 920 does.

Don't know if its in the new build but is it possible to have the raw module stay on the same rez, even after the camera is shut off? Like how ML saves the settings.

Want to help with the latest development but don't know how to compile?

apefos

920 x 518 in 16:9 will be better than 854x480 after croping the 960x480.

yes, enable the 920 width would be good!

920 and 944 added.. they are faster sometimes.

I don't think config files can be used with modules yet.

apefos

Hi 1% thanks for the 920 and 944 width!

Sorry for this question, (newbie question) but... how can I install the RAW video feature in the 600D?

I have the ML 2.3 instaled and working ok, so I am wondering the easy way to add the RAW feature (600D)...

1%

Replace bin and add module... lol

apefos

ok, thanks! I am already reading the topic about RAW instalation for beginers, I found it!

about the 920 and 944 width, will you upload this new feature  into a new zip file with modules in the tragic lantern?

apefos

I did the install, was easy.

Maximum resolution I could record was 960x408 at 2.35:1 aspect ratio, around 15.6~16.3MB/s

Anything more than this recording stops

Sound recording off, I did try RAW and SRAW, also did try Hacked mode on off.

I am using Sandisk Extreme 45MB/s (in card reader in computer it works at 28MB/s writing)

The buffer and card writing benchmarks on camera are more than 20MB/s so I do not know what is making the movie recording stops

RAW video playback on camera is always black and white

At 960 x 540, when I enable Skip Frames, many frames skips and recording continues at 18.2~18.7MB/s

At 1280 x 720, also with Skip Frames, recording goes on at 20.2~20.4MB/s and many frames skips

Maximum 16:9 resolution I can record without skip frames is 720x406, lower than DVD quality...

So I think enable 854 width would be good idea, because it will be usefull for 854x480 recording in 16:9, great for DVD work.

any ideas in how to make it works better, using 920x518, 944x532 or 960x540?

thanks

apefos

854 x 480 (16:9) will be a great option for sure. perfect for 16:9 DVD quality work.

it is the almost the same data rate of 640 x 640 and in my tests 640 x 640 works ok with frame skip off in continous recording.

854 x 480 = 409920

640 x 640 = 409600

maybe 856 x 480 will work better due to be multiple of 8?

apefos

with 640 x 360 and 720 x 406 I can record without skip frames and with simultaneous wav audio.

but...

in all resolutions I always get magenta frames. No matter 640x360, 720x406, 640x640, 960x408... all give me magenta frames.

Maybe some 600D are better than others, or the raw modules and bin need to mature???

Is there a solution?

NewNoise

first post here, thank you 1% for making this possible. now the 600d is a SD raw camera, too bad that the sd speed limitations allow me no more than 16 mb/s, btw since the latest updates I have noticed no more magenta frames and with the latest build the raw file looks more accurate to me (the magenta values are better than before) in photoshop. Hepefully you will be able to kill this speed limit, but it's probably a hardware thing...?

vicnaum

I've noticed that the RPP converter for mac does a bit better RAW processing than ACR & Lightroom - there is no moire or aliasing on small details. It's demosaic algorithm seems better.

Need to test it a bit further though.

1%

We'll get 12/10 bit when we figure out the registers to have canon do the chopping.

No real fix for the SD card speed.

If you're getting pink frames at such low res you need a faster card. I haven't seen any pink frames in a while.

Same here. Purple frames are no problem anymore.

And the shutter speed thing might have been a coincidence ... But I think we have to accept that the 600D is just not the right camera for raw video. Even with "throwing extra chroma away" (lossy) and maybe even  with Huffman compression (lossless) I doupt that we would get anything above 1280 X 720 :(

... Still I don't feel like getting a 50D instead of a 600D is a good idea. I would like to have both. Or just a 70D, if it will get a CF-card slot.

May not be the best camera for raw video but if its all people have then it might as well do it. 960x540 works for me and shrinking it just slightly to like 944 makes it even more stable. Upres to 720P or 1080P or letterbox its still nicer than the best H264. Wide lens helps with the crop factor.

720P full would be nice... I dunno, 6D doesn't do that either with 10 extra MB/s on my end. The sandisk 45MB/s people I think can do close to that continuously.

I think a better advance than just compression will be more memory... our buffer is only 96MB now. If it was 200MB you'd get usable takes on much larger sizes. Don't see many cutaways that last more than a minute....  You're probably not going to get raw hour long interviews but for other stuff its fine... and for this cheap too.

Lol... someone want to send me a 50D :) I bet price will be jacked on it real soon.

JohnBarlow

720x640 will give nice 720x1280 with a 2x scope :)

No doubt! Just the fact that Canon DSLR actually can shoot raw video is more than incredible! I remember the first day when Luke Neumann came up with the 14-bit silent pictures for the 5D Mark III and everybody in the comments was like "You're stupid. There's absolutely no way a 2850 € camera can handle raw videos. Stop dreaming and get a RED EPIC". And you showed them who are the stupid onces ;D

Even at 1280 X 400 the videos are very nice. The dynamic range ... I love it. I love ML. And I have faith that you can make at least the 50D to one of the best video cameras on the market! :D

You deserve one ;)

But I don't think that the 50D will get more expensive. It may be able to record video with Magic Lantern. But still most people use it for photography.

apefos

I will try another card...

Please, consider enable the 854 (or 856) width, very useful for DVD quality 16:9 (854 x 480)

and also, it is less data rate than 920/944/960
