Removing the Gemini watermark from video

No. The engine runs inside your browser, the same way the image tool does. There is no upload endpoint on this site. The ~44 MB the page downloads on first use is the processing code and model weights travelling to you — which is precisely why your file does not have to travel anywhere.

The removal itself does not — it is arithmetic on the watermarked pixels. The re-encode afterwards does, because the frames have to be written back into a video file. Raising the output bitrate reduces how much you lose but cannot eliminate it.

Veo output carries the same visible corner mark on consumer tiers, plus SynthID embedded during generation. The visible mark can be removed; the SynthID signal cannot.

The open-source CLI accepts .mp4, .webm and .mov. Which codecs work in practice depends on what your machine's video encoder supports.

Often yes, and it is the most predictable option. You lose a strip of the frame, but there is no re-encode artefact around the mark and no software to trust. For social crops that will be reframed anyway, it is usually the pragmatic choice.

Because a video is hundreds or thousands of images plus a decode and encode pass around them. A ten-second 30fps clip is 300 frames; the per-frame work is small but it is paid 300 times, and the encode is on top. A two-second 720p clip took about seven seconds in testing.

Veo output on the consumer tiers carries the same visible corner mark, plus SynthID embedded during generation. The visible one can be removed. On 720p output the tool matches a preset of 44×44 px inset 29 px from the right and 40 px from the bottom — asymmetric, which is why a generic corner crop often misses it.

Yes, here, at no cost and with no account. The engine runs in your browser rather than on a server, so there is no per-minute charge to pass on. The one cost is a roughly 44 MB download of the processing code and model weights the first time you use the video tool.

CapCut has no reversal of the overlay — the realistic options there are cropping the corner out or covering it with a shape, both of which cost you part of the frame. Cleaning the file first and then editing it keeps the full frame, and avoids the second re-encode that editing and exporting again would add.

Usually because the clip was cropped, resized or re-encoded after generation, so the mark no longer sits at a catalogued size and position. Heavy compression also damages the watermarked pixels themselves, and reverse alpha blending needs those values intact to solve for what was underneath.
