Videos generated by Google’s Veo (including clips made through Gemini) carry a small sparkle watermark at a fixed position, usually near a corner. Because the mark stays in the same place on every frame, its per-pixel opacity can be estimated and the original background recovered — then the whole clip is re-encoded to MP4 with the audio kept. Here is how to do it yourself, privately, in a browser tab.
Remove the watermark in 5 steps
-
1 · Save your Veo clip
Download the video you generated (MP4 is ideal). The sparkle is composited into the pixels of every frame, so it has to be edited out rather than toggled off in an app.
-
2 · Open the video remover
Open the Gemini / Veo video watermark remover. It runs entirely in your browser with no sign-up — the same tool handles both Veo and Gemini clips.
-
3 · Drop your clip in
Drag the video onto the drop zone, or click to browse. Nothing uploads — the aspect ratio is classified automatically and the watermark box is placed for you.
-
4 · Auto-remove and preview
Sample frames are analysed to estimate the mark’s per-pixel alpha, then every frame is cleaned — de-blended when the mark is translucent, inpainted when it is opaque. A split before/after preview shows the result; if the box is slightly off, drag it and it recalibrates on release.

5 · Download the clean MP4
Save the cleaned clip as an MP4 at the original resolution, with the original audio preserved. It is yours.
Why it stays private
Everything happens locally, so your videos never touch a server — you can go offline after the page loads and it keeps working. Wiper edits the visible sparkle only; invisible provenance marks such as SynthID are left untouched, and it is not affiliated with Google.

FAQ
Does removing the sparkle reduce video quality?
Only the small watermark region is modified; the rest of every frame passes through untouched before the final H.264 encode at the original resolution, so quality away from the mark is preserved.
Is my video uploaded?
No. All processing runs in your browser using Canvas and WebAssembly (ffmpeg.wasm). Your files never leave your device.
Does it keep the audio?
Yes. The original audio track is kept — copied as-is when it is AAC or MP3, and re-encoded to AAC otherwise.
