There have been lots of requests on the forums for a letterbox/widescreen effect which adds bars to the top and bottom of your video. Well, I went one step farther and added a couple more effects that let you have the bars appear and disappear. Here's a sample video of the moving letterbox effects.
Note: These effects take advantage of the effects architecture of Windows Movie Maker 6.0 and therefore will not work in XP. There are other solutions for XP such as a letterbox title.
There are two installers depending on whether you are running WMM 6.0 on a 32-bit or 64-bit version of Windows. The installer will put the necessary files into, C:\Program Files\Movie Maker\Shared.
Windows Movie Maker 6.0:After installing, you'll have new effects called:
Blaine's Letterbox Effects (32-bit)
Blaine's Letterbox Effects (64-bit)
