After cropping my videos to a 16:9 format using the previously mentioned How to crop a 4:3 video to 16:9 with Windows Movie Maker tutorial, I was left with a puzzling problem. Since Youtube disregards pixel aspect ratio (PAR), and widescreen DVD resolution files do no have square pixels, the only option was to encode the movies in HD 720p. Now this is great if you are dealing with HD video, but then why did you want to crop it in the first place. It is a waste of file space and bandwidth to use an HD output format on an SD video. So, I set out to create some custom output profiles for Windows Movie Maker.
