There is a way Kay tried to tell me how to do it, but it turned out I have Movie Maker 1.1 and you can only do it on the newer one, I guess. This is what she told me, hope it helps you better then me.


Open up Windows Movie Maker. Open or drag your video into the program.

On the bottom there's a thing where you can work on your video. Drag your video into that area.

Click on "view video effects" on the left side where it says Edit Video. The brightness option is the third thing on the list. Drag the brightness square onto your video on the bottom. You can do that as many times as you want until the brightness is how you want it.

When you're done, go to the left side where it says Finish Movie. Click on "save to my computer"
