Working for a church, I love open source (free) software that works really well and makes my life easier. Super is one of those programs. If you do any kind of media/video work on a PC, you should become familiar with Super. It will encode video from one format to another. While sometimes it can be a bit finicky, especially if your source video is of strange codec origins, usually a bit of trial and error will produce satisfactory results. If you don’t have Adobe’s flash encoder, Super is a great way to encode flash video. In fact, I use Super as the last step in generating my tutorials to create the flash file that you view online.
Check it out, Super.
(Just a word of warning, the Super website is a pain, you’ve got to click through several pages to get to the actual download page.)
