DE-INTERLACING IN AFTER EFFECTS

METHOD 4: THE AFTER EFFECTS WAY

Then After Effects has it's own built-in way of dealing with fields. By correctly interpreting the field-order in the footage interpretation window, After Effects will know how to handle them. When checking the 'motion detect' box in the footage interpretation window, After Effects will try to detect what area's of the image contain motion, and what area's do not. Then only the moving parts of the image are de-interlaced, keeping original resolution in the static parts of the image, which would be a good thing.

This approach works even better when activating Frame Blend for the composition and the layer, which basically blends in some of the previous and the next frame. This can result in excessive motion blur, though, especially if the original shutterspeed was also low. Blending frames will also reduce image noise a little which is why I tended to use this method on noisy footage, to make it a little smoother.

ORIGINAL FIELDS	FIELD SEPARATED	NUDGED 1/2 PIXEL DOWN
ORIGINAL FIELDS	ROLL-OVER TO SEE ORIGINAL

The problem with this method, as with the previously described approaches, is that the parts of the image that contain no motion at all, are still processed somehow, and this results in a subtle blurring of the entire image.
