In node compositing, how do I delay a movie clip by any given number of seconds I am creating motion graphics first in black and white, before colorizing them.  I am doing that with only kinetic text and transitions. I am overlaying one video clip upon another, but I wish to delay an underlying video clip by 30 seconds or 30 frames (30fps). How do I do that in node compositing?
In Movie Clip Editor open N-Panel, go to the bottom and find Footage Settings. Here you can control Start/Offset frame, these values can be animated.
