So, as in the demo, I apply the mosaic effect, then apply the built-in matte. I then track a face in a street scene, as per demo, but even though still frames are fine, the video does not play back, just black. Tried to force render but again the playback is just a black screen....
Been having trouble getting garbage mattes to work as well, can cut out shapes, but no feathering, no expansion, and it doesn't render or playback.
