VP23 - Video Levels Not Decoding Properly

ALO wrote on 12/10/2025, 10:16 PM

I have no idea what's going on with VP23's two 8-bit modes. Putting a video-levels MOV on the timeline decodes to full range in an 8-bit video levels (legacy) project. Video levels HEVC/MP4 decodes to full range also. AV1 same thing.

in an blank project, adding generated media --> color gradient, levels correcting to studio, then rending that out as Sony AVC, putting that file back on the timeline correctly shows video levels in 8-bit legacy, but then stays in video levels if I switch to 8-bit full range.

Is there any logic to how 23 is handling levels in the two 8-bit modes? This is completely different from how 22 manages levels. Tested on two different systems

Is this the extended video setting in internal settings? Change to FALSE to return it to the old behavior.

Yes new behaviour in V23, look back through the forum posts to find out a lot about it. as Roger says it can be fixed to V22 behaviour by changing the value in the internal menu.

ran a forum search but didn't find -- could you link so I can understand what the new behavior is? thx!

Got it. Looks half-baked for now. The problem I have with this is there's no easy way for me to check what a clip's encoded levels actually are. Pre-23, could always flip into 8-bit legacy and see immediately what the levels are actually doing. No way to tell with 23 unless you disable the new default handling.

If you stick with the automated modes (full) it's genuinely useful, especially with converting color spaces to get the proper colors. Why it touches levels in 8-bit video is a mystery to me.
