Mysterious black line glitch on right side of video appears and disappears
I've been working with Premiere for over 13 years and I'm still stumped by this latest issue. See this video for the issue and it's weirdness described below. https://drive.google.com/file/d/15nCJ484LJuOECH_NElE1-rm39U12Uc95/view?usp=sharing
A glitchy black line sometimes with color shows up on the right side of a vertical video I'm editing. It shows up when editing in the timeline and in the program and source intermittently, meaning sometimes if I go back a frame and then forward again it's not there. Now the biggest issue is that this black line shows up in the final export as well. In case you're thinking it's an issue with the source file it's a prores 422 export from after effects in 1215x2060 resolution. But yeah again the fact that it sometimes isn't there on the very same frame is especially odd to me. The real kicker is that even if I use some of the methods below to shrink it's noticeability and output a new prores, when I use AME to convert that to h.264 the glitch gets more noticeable again.
Things I've tried:
- Process with Mercury playback and not use my GPU -- The line is thinner and appears less often but still there.
- Nest the sequence and then scale clip 102% -- the line is thinner but not proportional to how much I've scaled (see video linked above)
- Use adobe media encoder -- with or without gpu the same issue, bigger glitch with gpu, thinner without.
- Remove any effects -- There were very few on the clip to begin with but taking off only reduces the lines and doesnt make them go away entirely.
- Use a different PC -- Yeah same exact friggin problem
- Use different Nvidia drivers -- This happens with studio drivers and game-ready drivers
Thanks
