First off, forgive my lack of sustainable editing language, i'll try to be as forthright and semantic as I can.
I am editing a short film I made and part of the film I have people's reactions to noises in the house, it is one big file and I took it continuously.
I am now trying to edit it a bit like "Evil Dead", in the sense that I am speeding up the footage and skiping frames, hence giving it a little strange look.
I am using Boris Optical Flow, however, I am getting rather peculiar results. I chop import the footage into after effects and I apply Optical Flow, however, the footage actually changes and effectively applies itself to another part of the footage.
This is irritating to say the least and I was wondering if anyone had any other solutions?
I suspect the problem is with applying the optical flow filter to a trimmed clip. Precomp the clip in After Effects before you apply the optical flow filter and you should get the results that you were expecting.
