Hi everybody! I hope you are having a great month of December.
If you have a spare minute, I would very much appreciate if you could give me a hand. For two days I have been stuck on a very silly editing problem caused by an .mp4 overlay.
The overlay shows sparkles on a black background. To get rid of the black background I chose the usual 'add' in the compositing mode and it worked well. Then, as the size of the sparkles was too big for my music video project, and I didn't want them to cover the whole event either, I used 'pan & crop' to make them smaller and I pushed the overlay to one of the corners of the event. Weird thing, a greyish/whitish rectangle appeared in the event: the shape of the new (reduced) overlay.
Why is the background colour of the overlay grey while it should be transparent? Inexplicable and sooo annoying.
I have tried everything but nothing works, I badly need your help. Thousand thanks!
