Incorrect Color Matrix VUI in x264 for PNG image stream import - The_Tinkerer - 12.10.2022

I've been on a long break, so I'm still on the latest public release (2022.03.20.1).

If importing 8 bit PNG and specifying bt709 for the Color Matrix, the VUI for Color Matrix on x264 seems to be stuck on bt470bg:

This will cause a color shift on export to mp4.

It's easily correctable by just unchecking "to input" and selecting "bt709", but it should be reading the input correctly. Wink

Will look into it. Smile
For the future: Please, remember to attach a debug output.

Can't reproduce this here.
Will send you a link to my current dev version.
In case this also happens with the dev version, please create a debug output of the analysis of the source.

Yeah... it's been a while, I forgot about the debug output. Tongue

Does the dev version work for you too?

I'm not sure if it's "fixed" or not, but it appears to no longer be happening in the dev version.

Thanks very much.

Okay, then I fixed it a while ago in the dev version.
