I recently thought not being able to frame blend a comp was a bug, but the AE team straightened me out. AE doesn't see a comp as a series of frames, but as a continuous animation stream. This is a good thing. So if you have animated a layer in a comp and for some reason a downstream comp asks for a time that isn't right on a frame, AE will actually render that layer in the spot it will be at that time, not round off to the nearest frame. Because a comp isn't thought of in terms of frames, there can be no frame blending. But in this case, the thing inside the comp is footage which is thought of in terms of frames, so you might want to frame blend it. Turn on frame blending for the base footage and AE will do so. But in some cases (particularly 3D render passes) you want the frame blending to happen after the passes have been composited, so you really do want to apply frame blending to a comp. This is where Time Warp comes in. You might also be able to use Posterize Time. Brendan |
