Set Poster Frame not working as expected
I’ve tried several times to change the frame that shows up as the thumbnail on my After Effects animation when posted to Facebook/Instagram (or even as just the desktop icon image). I thought this would be very straightforward: move the playhead to the area I want represented as the thumbnail, go to Composition>Set Poster Frame. But still, the image that shows up as the thumbnail is just the blank first frame of my animation. Does anyone have any idea what might be going on here? I’m using After Effects CC 2019.
