pulldown removal which recreates 24p/23.976p as it is cap-

Up and Down Conversion
Standard-definition video resolution employs a 4:3 aspect ratio, and high-definition video resolution
employs a 16:9 aspect ratio. Up-conversion is the process of fitting standard-definition video (with a
4:3 aspect ratio) into a high-definition, 16:9 frame. Down-conversion is the opposite process.
PIX recorders have various options for up and down conversion:
Down-Conversion
Letterbox : Maintains the same height and width ratio. Results in blank bar at top and bottom of im-
age.
Crop : Left and right side of image is cropped to fit into 4:3. Results in missing image at sides of pic-
ture.
Anamorphic : Image is horizontally squashed to fit into 4:3. Results in a narrow looking image.
