Seemingly at random, After Effects has taken a still image from one of my clips and, wherever nothing else should be playing in a particular composition, it inserts this image into previews and renders. It used to just be annoying--it'd disappear in previews and renders given time for my computer to process--but I just rendered a test cut to an .mp4 file and it is strewn about all over the place. I can't get rid of it now no matter what I do.
A workaround occurs to me now that I could insert a blank still frame down the length of the composition but that hardly seems like something I ought to have to do.
Is anyone else encountering this? I saw a similar thread about changing a tick box in Keylight but that had no effect for me.

I have gone and educated myself a bit about this and, yes, that's the problem. Thanks so much for the tip, sir!
