I have a video that is 480x360 and I need to make it 640x360....but I don't want to stretch the video. I just want to add black in equal amounts to each side so it extends to 640x360.
I have Handbrake and Avidemux and I don't see a way with either (unless I'm missing something?)
Avidemux: "Add Borders" video filter.
Thanks, I added 80 to each side and it worked.
