If that helps, I am using FFmpeg version 0.10 I've downloaded from
ffmpeg.org. My XCode version is 3.2.6 64-bit. And Im on iMac i7 with OSX
10.6.8

I've also uploaded short file I am using to convert:
www.rendertom.com/downloads/_in.zip
And the output file is here: www.rendertom.com/downloads/_out.zip

The code in terminal is this:
ffmpeg -i /_in.mov -vcodec prores -profile 2 -aspect 16:9 -s 1024x576 -an
/_out.mov


I've done this conversion on two different machines with same results. So
either it's me doing something completely wrong or there's some kind of a
bug in ffmpeg.

And again main problem is that the output file is NOT REALLY a prorez file.
Because if I add it to FCP timeline it plays back OK with no problem, but if
I do export with "make self contained" disabled - it exports full file, that
takes as much space as exported from ffmpeg.

And also native prorez files are fine with Cinema Tools - I mean I can
confirm them to any FPS I need, but the ffmpeg output file is not good -
Cinema Tools wont allow confirming it.

Please, if you have like three minutes, would you mind running my file to
prorez and then send me the output? Or maybe you could check it yourself?

Thank you.
