Thanks for the input. I re-interpreted the footage as 15fps and a couple of other frame rates, but it still inserts the color bar chip to indicate the abscence of a frame. Changing it to 15fps simply causes it to play the color bar chip for two frames instead of one.
This is fairly common for animators to render out only every two or three frames. There must be a way to stop AE from indicating a missing frame everytime the number skips a count like: 1, 3, 5, 7, etc.
Anyone?
