I apply any video effect in Premiere Pro to my 320x240 footage (uncompressed, square pixels, AVI captured from a Sony Handycam). I then save it as uncompressed AVI, square pixels. The resultant AVI is half the size of the original? Whats going on? Editing doesnt cause this issue. Are the effects designed to operate on video footage of a certain aspect ratios 4:3 or am I missing something?
