Keyframing question
I’m doing a somewhat unusal project using phone footage. The footage is at various low frame rates from 7 fps all the way up to 24 fps HD footage. At the moment i am matteing higher frame rate footage onto very jerky low frame rate footage and tracking motion or key-frameing it. The problem is that if the top layer footage moves smoothly from key frame to key frame then it doesn’t look natural with the low frame rate footage beneath it which is jerking along. I tried setting the composition settings to the frame rate of the base layer footage but that doesn’t seem to do the trick. The only thing i have found that works is to put a new layer in for each new frame of the base footage and avoid keyframeing altogether but this is a real pain. I could set a new key frame for every frame but thats also laborious. Is there a way to make AE move the key frames at the frame rate of the base footage? maybe some sort of parenting structure?

I’m not following you at all (What are you keyframing?) but I can suggest something from the audience’s perspective.
We don’t expect the footage in the window to be any better than the footage of the window. Your footage that appears on the phone, whatever its source, must be degraded to look and feel much worse than the footage of the phone.Try using Posterize Time to change the frame rate of the higher rez footage without prerendering it.
Hope you get better help over the next few days but that’s what I know.

You could try going into the project window, clicking on the footage and selecting interpret footage – main, then setting the parameters of the fast footage to match the settings of the slow footage. Not sure if it will help or not.
I also seem to recall a tutorial on time remapping that may have selected every nth frame. You might want to try a search for time remapping tutorials.

Posterize time is the one you are looking for, I think. See if that does the trick.
