My video is zoomed/cropped; please help!

My video is slightly zoomed in, cropping important pieces out, despite setting my sequence settings to match the resolution/dimensions of the video. In the picture below, the video on the left is what I want my project's video to look like. The video on the right, is what it actually looks like. Any ideas on how to fix this? I have spent many hours editing this project, and this is the last thing standing in my way! If you can fix this, I will send you a video of me attempting to do a backflip, and give you $10 through paypal.
