How AI Video Watermarks Work
Most AI video platforms use watermarks as a conversion tactic. They show you impressive generation quality — then deliver that quality with a large, centered brand watermark burned directly into the video file. The watermark is encoded into the video pixels, not overlaid as metadata, which means it can't simply be removed without significant visible quality degradation.
The calculation is: make the tool look impressive enough to get you to try it, make the free output unusable enough to push you to pay. Wurt.app's approach is the opposite — give you real, usable free generations so you evaluate actual quality before deciding to buy more credits.
