Ok, as already mentioned, I'm having a problem with recreating some (exactly 50%) "missing" frames, or otherwise with Pixelmotion. So the problem is: how do I recreate 50% of all frames (my source footage was scanned/imported by FCP at 25fps, but in fact is 12.5 fps, so every frame is repeated twice at these 25fps) using Pixelmotion in AE CS5.5?

What I tried already is to have AE play the footage at 200% speed, then precomp that and have that precomp play at 50% speed, so I then had 100% again. I couldn't "loose" any frames, as although this method only leaves you with 12.5 frames (not per second, because it's playing at 25 fps but only with 12.5 frames, right?), I already started with only 12.5 fps. However, when I then tried to apply Pixelmotion and turned it on in the comp, it didn't work! Maybe my idea to combine a change in time (so AE will be able to apply Pixelmotion) and having the footage play at 100% didn't work or doesn't make sense, HELP PLEASE!

Thank you very much in advance!

If I'm understanding correctly, you need to render your images out of AE at 12.5fps (so you only have one image at a time, instead of two repeating images). Then reimport that, interpret the footage for 25fps, drop it into a comp, double the comp's duration, apply Timewarp, set the speed to 50%, etc etc.

But the key, I think, is to pre-render the 12.5 fps movie.

hey at AEScripts u can find two very useful scripts for AE:

1. Duplicate Frame Remover

2. FrameRestorer

for frame restorer i think twixtor will do a better job compared to timewarp, So just copy paste those keys to twixtor.

Thank you very much for your responses! I will check those two (three) methods out now!
