How To: Do a picture in picture effect in Sony Vegas

ConnersTutorials, teaches you how to put two videos playing simultaneously in one movie. You use Sony Vegas and drag both movies in the time-line below. Then you press Event pan/crop on the first video. Right click and choose Match output aspect. Then re-size and move the video as you want. Do the same for the other video. Go to Media Generators to choose the background, which can be a solid color, a picture or another video. Just drag that down in the movie time-line when you're pleased. All you need after this is to save your new movie file.
