Rotoscroping in AE does a good job for the most part, but when the footage has fast motion blur, it really messes up badly. I agree with you about the brutal part.

I might give Silhouette a try if the end result doesn’t look good. Thanks for the suggestion.

Also, I have a Neat Video’s Reduce Noise effect applied to the footage layer. In which order would the results be better: Reduce Noise first then Roto Brush, or the opposite?

Thanks! Rotoscope is pretty awesome!

I have one problem though; it’s the fast hand movements causing the motion blur to throw it off. Would you suggest I include the motion blurred part of the hands in the “green” rotoscope area or just guess the approximate position of the hand without the motion blur? (I hope you understand what that means.)

Apparently, it’s Variable framerate. But when I imported it into After Effects, it became 30 fps.

So are you suggesting that I should make my MAIN comp as 30 fps, put the iPhone5 footage and my other 29.97 comps that I’ve previously worked on in there, and just work normally? Then at the end, render the whole thing as 29.97?

Ok another question about frame rate in general:

When is it a good time to use 23.976 and when is it better to use 29.97? Please give some examples.

Kevin, can you give some examples of what you mean by going to film? As in trailers or commercials?
