Broken preview in PP: update with workaround but still problematic

Hi guys, here's an update on the greyed-out preview problem I'm having with PP (newest PP24 version, Mac M1 w Monterey). The preview function was not working with .mov files that I exported from PP using JPEGs from a timelapse sequence. Yellow/green preview bar greyed out, and "render in to out" function doesn't work. The file is 8k in ProresHQ. Preview function and render in/out works fine otherwise with all other kinds of footage.

Then I tried exporting the same file in Prores422, same .mov format, pixel dimension, etc. and now the preview functions works normally. So there appears to be a bug in PP where it greys out the preview function with .mov files that have been created in PP in ProresHQ. Other things I tried: export with and without audio, and with/without metadata. Same results: .mov in HQ greyed out, Prores422 preview works fine.

Would be nice if Adobe could fix this because I would like to be able to work in HQ for obvious reasons. Many thanks for any additional thoughts, etc. Cheers to all.

Hi Matt, another update: I closed out the project (which I had originally started just by dragging my ProresHQ file onto the timeline) and started a new project (did the same thing again), and now the HQ file works with preview. I can't figure out what the difference was, as all the settings stayed the same. It's troubling to have had that issue for so many days, and then it disappears, because it is likely to resurface when I'm deep into my new film project. Hopefully someone else will have the same issue and it can be tracked down and solved... Anyway, cheers and thanks.

P.S.: the Prores file is 29gb and the ProresHQ is 40gb.

Hi Matt, many thanks for responding. Here are some screenshots, first with the Prores422 file, then with the identical ProresHQ file. Both files were exported from PP using the same set of JPEGs. You can see the preview function working normally when the Prores422 file is on the timeline, and then the preview function disappears when the ProresHQ file is added. Same result if I start with the HQ file alone on the timeline: preview is greyed out. Pixel dimension of the file is 8256 x 4621px for both files. Sequence dimension is 4KDCI (4096 x 2160), but the preview stays greyed out however I set the sequence dimension.

@coolseattledude Could you share some screenshots of what you're seeing? Is it only happening in sequences of a certain frame size? The codec of the clip in the timeline shouldn't matter. Thanks.
