HelpTube1 teaches you how to create a watermark for your videos using Adobe Fireworks CS3. Create a new 100x100 pixels file, with a transparent canvas. Create the custom shape that you want. You can add borders and colors, but make sure you don't overcomplicate your design, as people seeing your video will not be able to decipher it. You can also add a short piece of text, preferably in the middle of your watermark. Go to file and save it as Fireworks png. You can then bring up this file in "Camtasia Studio" or "Sony Vegas" and place the watermark in the video.
