Last frame carrying over to other clips
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.
