DE-INTERLACING IN AFTER EFFECTS

METHOD 2: BLENDING THE FIELDS

A little more refined approach, based on the first one, is to duplicate your footage, creating two layers of the same footage on top of eachother. Both layers are then de-interlaced using the Photoshop filter as described in method 1, but one layer is set to keep the odd lines, and the other layer to keep the even lines (set for interpolation not duplication). Set the transparency of the top layer to 50.

Now you have used the full pixel-information of the original footage, but re-arranged them to a non-interlaced image. This approach often increases the size of image grain slightly which can be problematic for grain removal purposes.

ORIGINAL FIELDS	INTERPOLATED	BLENDED UPPER AND LOWER
ORIGINAL FIELDS	ROLL-OVER TO SEE ORIGINAL

Although this procedure is a little bit more accurate then simply throwing away half the vertical resolution, the image can be a bit fuzzy. As you can see in the blended image (on the right), it also adds sort of a motion blur effect, which can actually be very nice.
