I have Handbrake and a program known as Handbrake Batch. I want to take file.avi or file.mov and convert it to something iTunes compatible (for use on iPad or iPhone) but I don't want to change the resolution. If it is 640 x 480 I want to KEEP it like that. Or if it is some weird thing like 700 x 400 I don't want it to change. I just want to change it from avi to m4v or something keeping the same aspect ratio. How do I do that?!
