OBS tip: if you want to use video sources (or Stinger wipes) with pixel-perfect display and alpha channels, use the ffv1 codec. It supports RGBA, so it plays well with PNGs and other RGB content. ProRes 4444 on the other hand has some nasty chroma siting issue.

How did you even counter this? So many of your obs issues seem to resolve around high quality output, but honestly I feel like I can't imagine the usecase you're hitting given the endpoints for content consumption.

You need pixel perfect mixing to line up overlays and transitions and stuff like that. Even if the output gets muddied by compression on the way to Twitch, seams are still very obvious and visible, as is chroma suddenly being messed up horizontally.

Fair, I'm just wondering why other people aren't noticing, also wondering how prores encoding is involved, is that the source?

There are few video formats that support alpha channels properly, prores is one of them (and commonly used e.g. with After Effects).

Okay fair point. I still don't understand why the aac codec/obs people got into a fight with you rather than actually doing anything
