(compressed\\uncompressed) no bit rate recognized. no depth ...

• Built-in alpha channel support Why alpha channel support is useful to the point of necessity will be covered further on in this document. Note that both DNxHD and ProRes 422 only offer fixed bit rates, and neither provides alpha support in video color space.
