Video Edit Frame Boundary Issue

[milosziv]

I was recently conforming to a video edit that had changed, and I normally group all my old tracks (including video) and make edits on all of them and slide around until the conform is done. This time though, when I would make an edit on a frame, I'd see it actually cut it correctly on the audio tracks, but the video edit was on a frame early, or late. Depending on where I made the cut, it could be even 3 frames early or late - until you'd find a frame that was spot on. Anyone encountering this? I'm on the newest PT 2022.9.0, on a Mac Studio, and the QT's were H264's at 23.98

Off the top of my head, might be because the h264 video is long GOP. You tried with an MXF picture instead?

No but thanks for pointing me down that direction - just read all about GOPs - and will try a conversion next time - just never hard to do this before. Many thanks Pete
