I'm seeing an issue I have never run into before in Premiere. I'm editing a sequence with a bunch of still images and clips (mix of 4k sources). Throughout the timeline, I'm finding that if I place the playhead at the beginning of a clip (first frame of the clip, the clip is automatically selected in the timeline), I see the last frame of the previous clip in the program monitor. This frame seems baked into the clip. If I move it elsewhere, it still has one frame from the original assembly order on the front. With most of the video clips I can roll the clip by one frame or trim the end and it goes away, but I'm finding that this isn't working on the stills: I can roll multiple frames or ripple trim the end of the clip and I still see one frame of the old previous neighbor in the clip.
What is going on? Is there a common mistake I was making during assembly that caused this? I can't see any transitions on the clips that would be holding frames from another clip.
Update: Just tested again to verify: Deleted a still, openend the source up again in the source monitor, dragged it into the project on a new track, trimmed to length to fit where the old still was, dropped it in. First frame is again the previous clip. Moved it back out to a new track at a different timecode, checked, first frame still shows previous clip from the original position.
What setting is switched on that I am unaware of? What am I missing? What tool am I using wrong?
The issue seems to just be in playback. I've not seen issues with this editing machine before for this type of content, but the erroneous frames I am seeing are not in exported media. I will see if I can fix the issue for editing comfort, but I may need to proxy the clips.
This seems a little odd, RB. If you upload a screen recording, I might be able to offer advice. As it is, I have never seen this behavior before and I'd like to see it in action to write it up for devs.
