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 .....

What happens if you don't specify -vcodec proves?

Hello Carl

At least one output file must be specified
But as you can see, ffmpeg shows that the pixfmt is yuv444p10le (10bit). But this file should be a 12bit file.
