I have some video files, and converted them to applicable format and imported them to PSP. The problem is, when I play them in PSP, there are black edges in left and right side. My source files have no black edges at all, I really don’t like them. Could someone tell me how to remove the black edges? The tool I’m using is ImTOO PSP Video Converter.

It’s about Aspect Ratio and Zoom Mode. Your source video aspect must be 4:3, while the screen aspect of PSP is 16:9. ImTOO PSP Video Converter should have converted your source files to videos with 16:9. when using Letter Box mode to convert source video, black edges will be added in its left and right side, then target video will become 16:9. u can try Pan & Scan mode, thus source video will be enlarged and clipped, but no black edges.
