Hello,
I want to test ifthe ProRes4444 of the ARRI Alexa are real 12 Bit? Is
there method to proove it with ffmpeg?
AS far as I know ffmpeg is only ready to open prores with yuv422p10le and
yuv444p10le (10bit), but no 12bit.
Last time I checked/tried, it wasn't possible. The best I got was a
statement by one developer that, looking at the code, it would be
theoretically possible to support more than 10bit, so my understanding is
that ffmpeg currently destroys any headroom beyond 10bit but since I am not
qualified enough to read the code, I cannot be 100% sure.
Hi Robert thank you.
The interesting thing about this is:
If I give ffmpeg the option to interpret the file as PRORES it can be
opened.
ffmpeg -vcodec prores -i inputfile .....
best regards
chris
