I have two movies considered as images (because I need to set up the beginning frame, offset ...) and I want to concatenate them so that one appears before the other one.
Is there an operation in the compositor which can do this ?
As mentionned here :
docs.blender.org/manual/en/dev/compositing/types/color/mix.html
the mix node needs a background image and a foreground one. I don't want to mix but to put one movie one after the other after specific frame.
