AE loop, missing frame
Hi,
When I loop my animation using the loopOut cycle expression the final frame in each loop is always empty despite that the fact that it is never empty in my precomp. Can someone tell me why this is, or at least how I can fix this?

I think you’ll actually find that the last frame in your pre-comp is always ’empty.’ For example, a comp with a duration of exactly 30 seconds only lasts until 29;29 (in AE 00;00 is a frame too!). When you time remap a layer it allows you to keyframe from 00;00 to 30;00, but 30;00 isn’t technically the last frame in the comp, it’s the frame after the last frame! Just change the last keyframe in your time remap to 29;29 (or subtract one frame from your comp’s duration) and move it back one frame in the timeline (alt-left arrow/opt-left arrow).

Even when I move the keyframe, I still get the missing frame of animation. I made another precomp where I made the sequence one frame less than the previous comp and then did the time remapping and it worked.
Seems like a silly extra step to do to make a loopable animation.

[geckorion] “Even when I move the keyframe, I still get the missing frame of animation.”
What gets rid of the blank frame at the end of the composition isn’t moving the keyframe. You need to give the end keyframe a new value, 1 frame less than it is by default. The last keyframe in a time remap of a 30;00 sec layer will be 30;00. You need to change it to 29;29 (not it’s position in the timeline, the keyframe’s actual value). Moving the keyframe back one frame is only to adjust for the fact that your last keyframe is now 29;29 and not 30;00.

Gotcha, that works. Thanks for the help.
