[XSI]

My friend is making a project and he want a watermark on the video made for the project. He asked me about a software to place a watermark on video. I need your help. Does anyone know about such a software?

For video?

Generally, there are not many free programs that are simple and easy to use. Also, this should be done to high quality source video because it will result in degradation in quality if you try to do that on already compressed video.
