I have various recordings made with MythTV and Kaffeine from UK DVB-T Freeview. I want to put these on a netbook for the kids to watch on holiday, but want to get the file sizes down from around 2GB/hour to something more reasonable. XVID would probably be a good format. I plan to play them using VLC and would prefer if the widescreen recordings automatically played back in the correct aspect ratio.
Ultimate quality is not the objective, just something that looks okay on a small screen.
Does anyone have some scripts for something like ffmpeg or mencoder to do this? These apps have many options and I don't have the time to try all the combinations. I'm sure someone has already been through that and will be willing to share the results.
