UMark Video Watermarker provides a quick and easy way to add text or image watermarks to videos.

Choose an image or enter your preferred text and you're able to set the watermark position, transparency, font, text style, position and more.

Unusually, your watermark doesn't have to be static. You can have it move to a random position after a predefined time, or scroll across the screen, making it much more difficult for others to remove later.

You're able to combine as many watermarks as you need. One text watermark, two, one text and two images, it's up to you. Each one has its own independent settings.

A straightforward interface means you'll be up and running right away.

The free edition has two important restrictions. It doesn't work with movies longer than 15 minutes, and it doesn't support batch processing.

The $29 Pro build removes these issues, and adds the ability to convert video formats, remove audio, limit the output size and save the watermark, so you can easily apply a favourite scrolling transparent watermark to other videos as required.
