How to remove a logo or watermark from a video
Upload the video to Vizard Agent and say which mark to remove. Vizard Agent extracts full-resolution frames, crops into the corners to read exactly what is there, works out the pixel coordinates of the mark, and rebuilds that region alone. Everything outside those coordinates is left exactly as it was.
What do you type into Vizard Agent?
Name the position and the wording if you know it. Vizard Agent reads the corners itself, and giving it the text is the fastest way to be certain you're both talking about the same mark, particularly when a frame carries two. Say which branding is yours and must stay, such as your own logo or a sponsor bug.

What does Vizard Agent actually do?
Almost the whole run happens before any pixel is changed. Vizard Agent finds out precisely what is there and precisely where, because a rebuild that is off by ten pixels looks worse than the mark did. A blur box announces that something was removed; a rebuild of what should have been behind the mark doesn't. In the session behind this article it:
- Extracted frames from the video to see the marks, checked its technical information and read several frames as a set.
- Extracted a full-resolution frame and cropped into the top-left and bottom-right regions separately, reading the logo in one corner and the watermark text in the other.
- Worked out the exact pixel coordinates of the white logo, and separately of the text.
- Cropped the text alone once more to confirm its position, so the rebuild wouldn't land on slightly the wrong rectangle.
- Rebuilt only those regions and kept the source's 720x1280 resolution and 25fps frame rate, with the audio preserved, in a 20.08-second file.
When does this not work well?
The rebuild is generated rather than recovered, so it depends on what the mark sat on. A watermark on a static sky disappears completely; one over a face, text or a patterned surface is rebuilt approximately. A tiled full-screen watermark is closer to impossible than hard, travelling bugs need tracking, and removing a mark doesn't give you the right to use the footage.
Common questions
Can it remove a watermark from a video I downloaded? Technically yes. Whether you may use that footage is a separate question, and removing the mark doesn't change it.
Can it remove my old logo and add a new one? Yes. Say both, and Vizard Agent puts the new one in the same place.
Can it handle two marks in different corners? Yes. Vizard Agent treats them as separate regions with their own coordinates, so one can go while the other stays.
