Editing video from VHS tape capture, which always has an unstable frame rate, I noticed that in some parts the screen started to blink green.
I changed the cursor to start over from another point and the problem stopped. I didn't pay much attention and rendered. The worst happened. Flashing snippets of green screen appeared in the final video.
I opened the same project without any changes on the PS24U, rendered with this one, and everything was fine. I'm going back to the PS24U.
Complicated.
