cool windows movie maker effects

How do you add special effects using Windows movie maker? HELP!!!?
I want to make a video using Windows movie maker and want to figure out how to make certain effects that I have seen on youtube. I don’t know for sure if they used Windows either I’m pretty sure they did. But I want to know how they did a flashing that looks like a strobe and how to do the strobe thing using different color too… If you know what I mean please leave a comment and help me!!
Oh yeah and if you know any other cool effects to use for action videos. And if your not able to do this with Windows Movie Maker what program would I need??????
doing the strobe in windows movie maker is really easy, but I don’t know what strobe you are talking about, any way, this is the simplest way
import a video to movie maker
add two or more clips to video timeline.
click on any video and click video effects, then select any effect you want, try them, you will find many of them looks like a strope.
if you failed to do so, try windows movie maker help.
