I'm having problems when build Timewarp into a clip.
I apply the effect and set first and last frame to slow it.
Then, when play the clip, some frames appears brokes liked you could see on the image below:
It's happening since last update software.
I run AE CC 184.108.40.206 over Mac OS X Yosemite 10.10.5 and Timewarp v1.0
I hope for your answer
220.127.116.11 is not the latest version of AE.
