Me again, sorry… I have created an opening sequence of a TV with static. The TV stays still and the static moves, just like real static.’
The TV is a graphic that I removed the screen and replaced it with a transparent PNG and then saved it as a PNG. I did this in GIMP.
The static is a .MOV and works fine.
The issue is that when I render it, there are small artifacts floating on the screen which are not there in the PNG image. (See the image)
As I said, they are not on the TV png as I dropped a black background in and the artifacts were not there. Also, they do not move, they are stationary.
