Canon XF-AVC Intra 4:4:4 L5.0 now incorrectly interpreted as legal range

[Jerome Raim]

I have C300 MKII footage that is Canon XF-AVC Intra 4:4:4 L5.0.

Previously, I was able to import the MXF into After Effects and it was correctly interpreted as full range (ie, did not apply a legal to full). This matched how Resolve (auto) interpreted the material.

In After Effects 23.1.0 (on M1 Mac Studio), this same material is being read as legal range and applying a legal to full transform.

Please revert the proper interpretation of this material, or, even better, allow users to override After Effect's auto interpretation of legal or full.

Hi Jerome, 

Would you mind sharing an XF-AVC 4:4:4 file with us? Our more recent Canon cameras don't support 4:4:4 and while we have sample footage from the older cameras, I'd prefer to make sure we're working with good test footage. 

Thanks!

Thanks John! Worth noting Premiere exhibits the same issue.
