i'm editing a video in adobe premiere pro and i'm trying to crop 25% of the width from the left and right sides, which i thought would resize the video when exported from 320x240 to 160x240 (50% less width due to cropped area being removed). however, when i export it, it is the same size, but with a black area filling in the area i cropped, which sounds the same as a clip effect. i also tried changing scaling under "motion" in the fixed effects section, and then scaling using the transform effect. but no matter what i do, the result when i export the video to .avi has black area around the video.
can someone please explain how to crop the actual horizontal size of a video so that the exported video is resized to the cropped area?
