LoopOut() Problem

[dgregowich]

I have a precomp with sequenced layers. I want to loop it in another Comp. I used this route which always used to work for me:

-Trim pre-comp to the work area as long as the layers go.

-Enable Time Remapping on the pre-comp

-Extend time of the pre-comp

-Alt-click on the Time Remapping

-LoopOut() expression

-Create a new keyframe before the last keyframe

-Delete the last keyframe

For some reason this no longer works, the pre-comp loops, but I still get one black frame in the loop. I did these steps in different orders, just in case, and still no difference. What could I be doing wrong?

I'm using AE 2020.

Make sure that the first and last keyframe show you an image by turning off the loop expression and using the J and K keys to move back and forth between those frames.

Hi Rick, yes, first and last keyframe show an image. But meanwhile I discovered that when I don't do the "put a keyframe before the last keyframe and delete the last keyframe" step, it actually loops properly without the black screen. So odd!
