I f****d up and changed the framerate of my AE preview because the project began taking its toll on my computer, mistakenly thinking that this will increase performance. However I sadly had to notice (after continuing to work on my project for quite some time) that this only affects the playback speed. And herein lies my problem: Everything is twice as fast as I had animated it. As a workaround I simply put everything in a precomp and enabled time-remapping, however this feels more like some makeshift solution rather than something proper.
Now here is my question: Is there a way to tell after effects to stretch everything (layer length, keyframes, etc.) so that they are of correct length? Or do I have to rework everything manually what will probably make me never forget the difference between skipped frames and framerate again? :D
