Am I blind, or is there no “end frame” option for image sequences in the compositor? There must be a way to do this, but I have not figured it out. I’m trying to composite in some laser shots, and only need them to appear in 20 frames of a 360 frame animation. I can get them to start at the right time, but when they end the last image sticks around for the rest of the animation.
You might be able to do that in the sequencer better.
You can fade it to black with a set alpha node, a time node and a math node set to multiply X 1. Then you set the time node from full on to full off over the course of 1 frame. It looks like the following image.
I came up with a workaround, but I can’t believe there isn’t an option to deactivate the last image when the sequence is finished. It’s so obvious to have that there.
