Hello. AE CS6 User here.
I have 100fps footage I put into a 25fps sequence. When I apply the effect "timewarp", set speed to 25% it does interpolate the frames in between and shows ugly morphs. Why?
Second example why the effect is not working: If I set the render options of timewarp to "whole frames" (instead of interpolation), every 4th frame a new frame is shown in my comp.
However, it then should show every frame in between since 100 frames slowed down to 1/4th speed is 25 frames. Or am I doing something wrong?
How can I fix this? Apparently, the highest allowed framerate for comps is 99 so that isn't a workaround either.
After continued experimenting, I've found out the only way to work with this footage is to use CTRL+ALT+T for time remapping. I'm curious as to why the effect "timewarp" is overwhelmed by this footage.
I'll keep this up in case anyone else finds a better solution or stumbles across a similar problem. (I've never used 100fps before)
Your approach is completely backwards from the way I would do it.
Select your 100 FPS footage in the project panel and then right click and go to file interpolation. Change the frame rate to match your comp and you will have slow motion footage in your comp that shows every frame. If you need to slow it down even more then enable time remapping.
Aah! Now that makes it a lot easier I forgot about the file interpretation. Thank you!
