General Development / Re: uncompressed 14-bit RAW video recording
« on: May 26, 2013, 03:20:55 PM »
No ae here, all open source  ;D  My workflow is Raw -> dng -> Tiff -> ProRes 422. Using DCRaw and ffmpeg. My goal is to setup a automatic system, where i put in the CF Card and hit one Button and end up with ProRes including Audio. Still having the Tiff if i need them.

I still get corrupted CF Card though, after Footer Save Error. Preety preety Bad ;-)

this is the command to convert tiff sequence and wav to ProRes 422 with ffmpeg. Will do some more tests now if the Audio is in Sync.

My first Post, so thanks to all devs and others for your work.

Recording Raw runs fine on 5d III, since i disabled Raw Photo and set Jpeg to S3 ;-) (no idea if the S3 does anything) I can even enable Overlay with Zebra, Focus, Histogram, Waveform and it still records fine in 1928/960. It however, in some cases, is not able to save Footer, usually if ran out of Buffer, but as well on ordinary video stop occasionally. Now, if this happens and i continue to record it usually is not able to save Footer for the following recordings. It happens as well then frequently that the Filesystem on the CF Card gets messed up - not read/writable by 5d III anymore - so renders card unusable in field! Have to reformat in mac then. This is bad, since i've got only one fast Card yet...

Another issue i have is Audio. I try since several hours to get the Recorded Wav from the 5D III in Sync with Video in ffmpeg. No matter what i set on camera 23.976/24.001 Frames or in ffmpeg vsync, async, audio offset, 23.976, 24 frames - the Audio always goes out of sync pretty badly even after 7-8 sec. It appears the sound is faster than the Video.
So my questions (to start with):

Has anyone in any software being able to Sync Audio (recorded in Cam to Wav) with Raw footage?
If so, where and what and how, you know?

is 5D III Wav recorded in 48000 Rate? Any way to set this in Camera?

I've noticed the Audio Length is 00:00:14.76 while the Video length is 00:00:14.50 (according to ffmpeg)...

And another one - Bitrate setting for 5d III H.264 is not working? Nothing happens with h264.ini (or how it's called..)


EDIT: I just see: ffmpeg to avi is in sync
ffmpeg -i %6d.tiff -i M0000000.WAV -acodec copy test.avi
but prores_kostya isn't...

EDIT 2: Forget the Audio thing, i think i solved it. Probably messed up some flags. This is working:
ffmpeg -i %6d.tiff -r 24 -i M0000000.WAV -async 1 -vsync 0 -vcodec prores_kostya -profile:v 3 -qscale:v 6 -vendor ap10 -pix_fmt yuv422p10le -r 24 -threads 4 -strict -2 -y
