I’m having inconsistent results rendering a sequence with a movie background.
The problem is that when rendering with a scene overlaid on top of a movie, the movie gets whitish on second render forward. Yes, the first render of the frame shows the movie fine, but the second one forward gets the white tinge.
To render another frame without the white “effect”, I have to click the movie and go to Strip -> Rebuild Proxy and Timecode Indices. Then again a single frame is rendered right, but the next ones go wrong again.
The strange thing is that I’ve tried with a different video, made with a different process, and it goes without the tinge.
I’ve attached the .blend file the zipped movie strip.
