I'm running into a strange bug with Premiere Pro 13.1.4.
I produce and edit online learning videos for a university, so I deal with lots of green screen footage. Lately the edge of the frame of my green screen footage has been glitching back into the videos, not just in the timeline playback but in my exports as well.
I've attached a couple of screenshots, one being the culprit against a while background and the second being the order of effects I have on the clip. Has anyone else run into this problem? I seem to recall having the issue once months before, but for the life of me I cannot remember how I fixed it.
It is indeed the edge of the original frame, and I do have a crop applied to trim that corner (see second screenshot).
It's not there permanently, it flickers on and off. When I'm editing in the timeline I can see it sometimes (mainly when editing titles) but literally any change within Premiere will make it disappear. Selecting a different layer, selecting a different tool, solo an audio track, and boom: it's gone.
That lead me to believe it's just a timeline playback issue and an exported version wouldn't contain the flickering corner, but alas, it pops in and out of the exported video as well.
