Google Flow watermark: size and position
The Google Flow watermark is a white, semi-transparent four-pointed diamond in the bottom-right corner. Its width is the short side of the video divided by 15: 72 px at 1080p and 48 px at 720p. It sits one and a half times its own width from the right and bottom edges, and is about one third opaque at its centre.

Measured on original MP4 downloads from Google Flow in November 2026, by fitting the diamond shape to each frame.
How the mark is applied
Every frame is blended with the same white diamond at the same strength: shown = mark × opacity + original × (1 − opacity). Because the opacity of each pixel is fixed, the original value can be calculated back, which is how the remover on this site restores the corner without blurring it.
Visible mark versus SynthID
- Visible diamond: in the pixels, can be switched off for new videos in Flow settings, can be reversed on existing clips.
- SynthID: invisible, spread through the whole video, stays whatever the setting, not removed by this tool.
- C2PA Content Credentials: metadata attached to the file by Google.
