Hi List,

Is it possible to determine the bit depth of the data inside a ProRes file? Perhaps there's some metadata that can be read...

I asked about this internally and received this answer:

It's not possible. The reason is that a ProRes file encoded from an 8-bit source will be indistinguishable from a file encoded from a 10-bit source whose two LSBs are zero.
