How can an alpha masked image (PNG with alpha) be overlayed over an already finished video footage?
I have a filmed (not rendered) Video footage with approx 40.000 Frames. Over the first 200 frames, there should be the mentioned overlay.
Everytime i do so, the whole video strip renders the wholel 40.000 Frames, even tough only the frist 200 were changed by adding the overlay. Is there a way to change only the first 200 frames by adding the overlay, and then "stitch" it to the unchanged remaining 39.800 frames?
Thanks for help!
