Loop Selected Layers → will skip/lose one frame on every loop (time remapping)

[LarsJandel]

Hey Zack!

As I was working on some perfect loops and did video previews with some repeats for easy reviewing the loop behaviour, avoiding loop point stuttering on a video player, this came to my attention:
I also was used to the old trick / workaround regarding looping precomps via time remapping and doing the adding on key prior to the last keyframe and then deleting the last key - just as your script does.
Well, it turns out, this will remove the one empty frame (or one doubled frame on clips), BUT this will result in skipping/losing one frame each loop 😱.
So, a proper fix seems to be: Doing as you / we all did all the time - adding one key prior to the last keyframe, but instead of deleting the last key, replacing it with the first keyframe.

I just did a test again, for precomps and an image sequence (which of course can get a proper loop via the import option) and attached it for you to have a look at it.

Cheers, Lars.
