Expected behaviour when shortening clips in keyframe editor?

This video describes the issue:

I'm trying to shorten the background clip in the keyframe viewer in Fusion and I can see it glitching between shortening it and retaining the full length. When I release the mouse it jumps back to full length.

Resolve 16.1.2.026
OSX 10.15.2

Thanks.

Mark.

Try unchecking the "Loop" checkbox in the MediaIn node of the files you are having troubles with. Then extend the global out through the Inspector or change the length like you were attempting in the video.

Thank worked. Thank you! I've looked up loop in the manual and I think I'm up to speed. Much appreciated.

Mark.
