4×3 center punched- extracting the 4×3 center portion from a 16×9 anamorphic image. Allow for generating a 4×3 image from the 16×9 anamorphic material which could be standard def or high def.

4×3 anamorphic squeezed- method to record a 16×9 anamorphic image into a 4×3 area. The result is the images are tall and skinned (ie squeezed and will be unsqueezed during post or via a monitor)

Upconverting SD to HD- the post production process of uprezzing standard definition image to high definition ie standard def 720×486 to High def 1080×1920. Process is more complicated when dealing with different frame rates ie 60i to 24P.

Up res – upsample or upconvert from a lower to higher quality codec, format or standard. ie uprez from standard def to HD, uprez from dv to 8 bit uncompressed codec.

Up converting any format is best done when the original material was progressive to start off with ie Standard def best done with progressive scan 4:2:2 720×486 material to High def 4:2:2 1080P, 720P or 1080i. Lesser quality when you start with interlace 4:1:1 and uprez to HD 4:2:2 progressive or HD interlace.
