I have a 320MB flv (Flash video) file that is 75 minutes long, and I want to change its width. The file is encoded with AVC (video codec) and AAC (audio codec) (like a typical youtube video, I think.)

Its dimensions are 720*480, but I want to change that to 854*480. I don't want to change the dimensions in the player, rather I would like to permanently change the file itself. I looked on the internet, and all I could find were tools like flvMDI (metadata injector), which don't really "inject" anything, instead they extract the information from an already existing file, and garbageware.

The closest I could get to doing this was was flvtool2, a command line program (I have both Windows XP and Ubuntu). It was doing something for a few minutes, but stopped with some errors.

Does anyone know a (free) program that can change the dimensions, crop, etc. for FLV's? If someone could help, I would really appreciate it.
