Here is a list of tutorials I've made for Windows Movie Maker that I found to be extremely helpful when I was just starting out. Adobe Premiere Tutorials will be out at a later date.
In the meantime, enjoy the WMM tutorials, and if you use them, some credit and a link to where I can access the video would be nice.
Also please be aware that to see the picture explanations, you must click on the thumbnails!
