Hey Steve, I also have an HV30, your black bars are border bars that are on your video to keep your aspect ratio in the format that you encoded them. To remove them, you simply have to go under your settings when your post producing your clip and adjust your aspect ratio. Do it manually, otherwise the render will keep the bars on top and bottom. Another words, 1600x900 as opposed to 1600x1200, or you can divide the horizontal pixel count by 2 and add that to your vertical count. If I am understanding your question correctly.
