Hi! LoopOut function on scale and opacity causes glitching. 

 

I have three keyframes. 

- Keyframe 01: 0% Opacity

- Keyframe 02: 100% Opacity

- Keyframe 03: 0% Opacity

 

With he LoopOut cycle function, it glitches and shows the third keyframe at 100% opacity. 
I use MacOS Sonoma 14.0 
After effects 24.0

If you scrub over the timeline, is the opacity value being shown in the timeline correct, or does it jump to 100%? I just tried to repro and don't see the issue.

It shows 0% in the value, but 100% visible in the viewport. I also tried replicating the problem elsewhere, but it wasn't so easy. I converted a 2023 project to 2024, where this issue showed up in 2024, but not 2023. 
I reduced the aep project to where this issue happens: https://drive.google.com/file/d/1jNyAjqq8_bpJuC14r6QyWsKcsvfW5S5u/view?usp=sharing
It seems like motion blur has to be on for the probelm to appear, and it has to be precomped a few times.

Thanks for the sample project. I opened it up and exported the workarea of the comp and I'm not sure I see anything wrong with the output. I uploaded the video here https://shared-assets.adobe.com/link/e417c306-60bb-48cc-53fb-fd68cb928813 - let me know if you see the issue and what/when to look.

 

I did export this on Windows. I see you're hitting this on MacOS 14 Sonoma. I will try there as well, though there are definitely some weird things happening with AE on Sonoma at this time so perhaps it's something there.
