OT: VLC player and ProRes 422 HQ

Jessariah67 wrote on 6/21/2021, 8:17 PM

So, on my timeline, a PR 422 HQ MOV master file render and an MP4 render from that same master file look exactly the same. But on VLC player, the ProRes MOV is noticeably darker than the MP4. At first I thought I might be dealing with the "Original" vs. "PC" Levels thing (even though VP18 fixed that and the "Original" is now the "real" state of the video, from my understanding?).

I'm pretty sure my QC place would've said something, but I'm just double checking to see if anybody else has experienced different codecs playing "darker" or "lighter" on VLC player?

Thanks for any insights!

I am betting the devil is in your project settings.

How would project settings cause the MOV and MP4 to look identical on the VP timeline, but one darker than the other in VLC player? Wouldn't it be the other way around?

Nope. Presumably, they are flagged different. Each format's level needs to conform to its own flag, not to each other. The Project Properties determine the output luminance, not the preview. Vegas won't plant VUI flags in MP4s, so your rendered levels need to be correct 16-235. Your MOV file might also be misflagged.

Try MediaInfo? https://mediaarea.net/en/MediaInfo

I don't use VLC so no experience with that here.

Does the same problem occur with other players?
