I was happy to see that Windows Movie Maker 2012 had native support for exporting MP4s; I really was. I've been playing with it, to see what's new, what's changed…
I was working with some video, exporting it to MP4 and I thought, that's a pretty big MP4 video file for being as short as it was…
The video was from one of my son's football games. Once all the video clips were imported the video was 4:50 sec. The resolution was 854 x 480, The original file was 87Mb and the other file with the same resolution and the same length was 56Mb… bandwidth wise, that's a big difference.
