I'm working on a project where I need to edit together clips of various resolutions(640x480 and 640x360). So to have all of the clips looking normal in the end I need to letterbox the smaller clips.

What settings are you saving/re-compressing with?
...some codecs like XviD have the option to set the bitrate.
I was using default settings for XviD

. I set the target bitrate to 1096 and the video clip is now only doubling in size which is far more manageable.
Thanks for helping a newbie out, I'm still not very familiar with VirtualDub.
