There is no ability to green screen or blue screen with windows live movie maker.
YES!!!In fact, it works better on XP than on Vista. On Vista, if you put music, credits, etc. into the movie, a green bar will appear on the bottom of the screen when you watch the finished movie.DO NOT use movie maker on Vista, use it on XP.I beg to differ. I use Windows Movie Maker v2.6 on my Vista machine and have NEVER got this so-called green bar appearing on any of my videos/movies. Ya'll must be doing something wrong during the Publishing process for that green bar to appear. And, I couldn't tell you what you are doing wrong, because it's never happened to me.Vista Movie Maker is just as good (better in my opinion) as Movie Maker for Xp.
Green screen effect is only available in Windows Xp systems.
No use adobe premiere or better yet adobe after effects

You can't add sound in Wax 2.0 at all, you have to add it in Windows Movie Maker afterwards.
There is not a Sonic Movie Maker but there is a Mario Movie Maker which you can get by following this link: http://www.newgrounds.com/portal/view/477182 Dj Green Dj
You have to click on the green arrow that says render(it renders quick so dont think it didnt render like me)after go to the file i would prefer putting it on the new version of the software windows movie maker and then publishing toyoutube P.S. Windows Movie Maker has youtube publishing on it so it is easier that way.. MultiExtraneous
if it won't come on and if the video is black, it needs to load. you can see how much progress it has made at the bottom. the newer version of windows movie maker is easier to tell, but i dont know about the other ones. if it is loading still the loading bar is neon green at the bottom. so it needs to load or you need to try again.
What aspect (size) did you select to Publish/Finish the video in? Try Publishing/Finishing the video to your computer (without changing the aspect ratio).
