uMark Video Watermarker has two modes - Free and Pro. For the first 15 days after you install it, uMark will run in the Pro mode trial. You can test the full functionality of uMark during this period. After the expiry of the trial period, uMark will run in the Free mode with certain features disabled. You can continue using uMark Video Watermarker in free mode for as long as you wish. If you like to make use of the Pro features you upgrade to the Pro mode.
