Raw Video / Re: 60D RAW video - it's working !!!
May 26, 2013, 05:11:05 AM
Ok here's some more experimentation,

Sandisk Extreme 16GB Class 10 45 MB/s writes at 20.1/20.9 MB/s

New Test

1280x720 - 23.976 - 340 Frames approximately 14.1 seconds @ 20.1 MB/s - Ratio 16:9
1280x544 - 23.976 - 710 Frames approximately 29.6 seconds @ 20.1 MB/s - Ratio 2.35:1

Last Test

1280x720 - 23.976 FPS - 227 Frames proximately 9.4 seconds @ 20.7 MB/s - Ratio 16:9
1280x544 - 23.976 FPS - 525 Frames proximately 21.8 seconds @ 20.1 MB/s - Ratio 2.35:1

To get these increases, I went into M mode>First Tab>Quality>Placed RAW marker on the - and then JPEG marker on S2.

I chose S2 first because it's save resolution was 1920x1280 but I'm not sure if that mattered at all since its saving the data from the camera before it hits the encoder (if I'm understanding it correctly).

I also gave S3 a shot but I got pretty much the same results.

Now I did the same process of raw2dng into ae interpreted the footage from 30fps to 23.976 added a simple curves adjustment and 25 points of sharpening and rendered out to H.264 then to youtube and these are the results. (Starring Kangaroo Plants again)

I also up scaled them to 1080 just to see what it looked like, I know its only Youtube but for the sake of time.

Pretty cool stuff that you can squeeze those extra frames out by increasing the buffer size, not sure if changing from RAW to JPEG actually produces a difference in image quality. I didn't notice a difference personally.

A record time of almost 30 seconds at 1280x544 is pretty awesome, I mean not many shots go over 30 seconds and you have plenty of edit room, unless you are doing interviews on long events ;P.

Great work guys keep it up :D

Glad I could be of help!

Got them for about $25 ea from eBay if my memory serves me correctly, SD cards seem to be very unruly in terms of read and write speeds. Would having a smaller card size have anything to do with it? Just out of curiosity.

Thanks !

It looks like your sd card is much faster than my sandisk ultra 64GB.. I've got only 199 frames on 1280x544.

hi there, i have a question..

when you rendering your raw in AE you compress the video to h.264? or something else?

thanks

Yeah just H.264 with a VBR of 10, I just shot the RAW into AE then out to H.264 and straight onto Youtube.

James, could you run normal nightly build, go to 1080p movie mode and run silent burst ? I would like to see size of your memory..

Can do, think I've done it correctly (first time doing this) I got 52 Images at 1734x1156 before it stopped. If you need any more info just let me know and with a little guidance I can do it.

OK so I've been messing about with this today this is what I got.

Sandisk Extreme 16GB Class 10 45 MB/s writes at 20.1/20.9 MB/s

1734x976 - 23.976 FPS - 91 Frames proximately 3.7 seconds @ 20.1 MB/s - Ratio 16:9
1280x720 - 23.976 FPS - 227 Frames proximately 9.4 seconds @ 20.7 MB/s - Ratio 16:9
1280x544 - 23.976 FPS - 525 Frames proximately 21.8 seconds @ 20.1 MB/s - Ratio 2.35:1

Highest FPS of three tests of each resolution in a row.

Ran through raw2dng.exe, Imported into Adobe Afte Effects

1734x976 - Couldn't parse file into AE
1280x720 - Could parse file into AE
1280x544 - Could parse file into AE

Here's a short video of the 1280x544 RAW at work just so you know it works, kangaroo plant. Interesting subject I tell you ;).

So yeah, exciting stuff, we'll see if this goes any where.

Awesome work :D
