How to make videos on Sony Vegas Pro 9?

Sony vegas brightness problem?

• Ok so I imported some small mpeg4 videos into sony vegas to make it one whole video. As I was in sony vegas pro 9, I rendered the video to the same files they were before; mpeg4. Once the video was done being rendered, I watched it and it seemed it made the video brighter, which isnt good because you can barely see the people's faces in the video I have because of how bright the light is. why does it do this and how can I make the video less brighter? I dont want to try rendering it to a different video format because mpeg4 is best for youtube. (yes i planned on uploading it to youtube as well.) I also tryed doing the same thing on sony begas 10 at my friends house, it still made the video brighter. someone help? how do I make the rendered video less brighter? is their a setting i can do or something on sony vegas before it renders it? because when I put the video in sony vegas and watch it on the preview screen, its not brighter. but when its rendered, it becomes much brighter. How can I fix this?
