it isn't absolutely necessary that i fix this, but i'm showing a video tonight that i've made, and i'm rendering them at full quality.
i had changed the project size from original to 320x240 (don't know why, but i did), and i tried to change the project file back to it's native size (720x480) for the full-quality render.
i know i shouldn't have changed it in the first place, but what's happened is there has appeared around my video a black "border" of sorts which seems to take up the space around the video.
i'm rendering three videos for this showing, and the first one worked out fine. i don't know what i did to the other two, but they now both have these irritating black borders.
any ideas on how to get rid of 'em? i've got until about 5:00 tonight (4 hours)
