Rotoscope not holding frames
I am using After Effects 5.5 and am trying to rotoscope 34 seconds of footage at 24 fps. After I do about 7 seconds the previous frames change and I lose vast sections of previous frames that are now not enclosed.
My workflow is to open the document/load the video/drop into new composition/select brush and start rotoscoping.
I thought once you completed a frame it would stay as you went forward in the video. I know you have to freeze frames but after doing that the previous frames are all off.
I guess the technique is good for about 4 or 5 seconds only, nothing larger. Thanks for your thoughts.
