To watermark your videos, you must use the Hue video transition. This video transition renders shades of gray transparent depending on the intensity of the transition.

Here are the steps to watermark your videos with the word "DeskShare":

1. Use Microsoft Paint to create a bitmap with a white background.
2. Write the text "DeskShare" in the center of the bitmap with a large sized font and save this bitmap. For best results make sure that the height and width of the bitmap is same as the video that you want to watermark.
3. Open the video in Video Edit Magic and add it to the Timeline in the Video 1 track.
4. Open the bitmap and add it to the Timeline in the Video 2 track.
5. Under the Video Transition tab, add the Hue video transition.
6. In the Transition settings of Hue, select "Keep Intensity Constant". Specify an intensity between 60 to 80.
7. Uncheck the "Invert Operation" option if checked.
8. Click OK.
