I rendered frame by frame with the roto brush to remove a person from
their background. I imported a new background from a photoshop file. I
exported the file with media encoder and the mp4 it create has parts of
the person randomly disappearing into the background. I go back to the
After Effects file and none of these errors are visible. I've used this
tool for 7 other videos in the last week and haven't had this issue.
Please Help!! On a deadline!
