Omni Flash Watermark Remover
Remove the Omni Flash watermark from Google Flow video exports. Frame-by-frame reverse alpha blending runs entirely in your browser via WebCodecs — original audio kept intact, resolution preserved, no upload. Works on every Omni Flash clip from labs.google/fx/tools/flow.
What Omni Flash is — and what its watermark looks like
Omni Flash is the compact, fast-iterating video model Google ships through Google Flow at labs.google/fx/tools/flow. It generates short clips quickly — typically 5–10 seconds, 720p or 1080p, landscape or portrait — and stamps a Gemini-style sparkle in the bottom-right corner of every frame. The Omni Flash watermark belongs to the same family as the standard Gemini Omni mark but uses a slightly different alpha map. Erasio detects the Omni Flash variant automatically on upload, applies the exact inverse alpha blend per frame, and re-muxes the result with the original audio track copied across unchanged.

Remove the Omni Flash watermark in three steps
Drop, process, download. Nothing leaves your browser.
Export your Omni Flash clip from Flow
Download the watermarked MP4 from labs.google/fx/tools/flow to your device as you normally would.
Drop it into Erasio
Drag the MP4 onto the upload zone — no account needed to clean a single clip. Erasio identifies the Omni Flash pattern automatically.
Download the clean MP4
Original audio preserved, resolution untouched, watermark gone. The clip is ready for upload to any social platform or ad network.
Built for Omni Flash specifically — pattern auto-detected on upload
Private by design
Files never leave your browser. The math runs locally on the Canvas / WebCodecs APIs — there is no upload step to leak from.
Lossless reverse-blend
Other tools paint over the sparkle with AI guesses. Erasio reverses the exact alpha blend Google used, recovering the original pixels.
Every Gemini variant
Gemini, Gemini Omni, Omni Flash, Nano Banana, Sparkle v1 and v2 — one engine, all patterns, kept current.
Who uses the Omni Flash watermark remover
Short-form content creators
Post Flow / Omni Flash clips to TikTok, Reels, and Shorts without the AI watermark down-ranking the post.
Motion designers
Use Flash-generated clips as plate footage, moodboard motion, or transition material in larger edits.
Ad creatives
Run Omni Flash motion ads on Meta and TikTok — both platforms reject visibly watermarked AI video on upload.
Omni Flash Watermark Remover — common questions
Is the Gemini Omni Watermark Remover really free?
Yes. The Erasio online tool is free for guests with no signup and lets you process a Gemini Omni image or short video right in the browser. Sign in (also free) to remove watermarks in bulk, queue multiple files at once, and download them as a single ZIP.
Do my files get uploaded to a server?
No. Erasio runs entirely in your browser using WebCodecs and the Canvas API. Your Gemini Omni image or video is read into memory, the watermarked region is patched locally, and the clean file is handed back to you — nothing is transmitted, logged, or stored on our servers.
Does removing the watermark hurt the image or video quality?
No. Erasio uses reverse alpha blending — a deterministic mathematical inverse of the blend Google used to stamp the watermark on. The patched pixels are the original pixels, not an AI guess. Images are exported as lossless PNG; video is re-encoded at a high bitrate so the output is visually indistinguishable from the source.
Will the audio in my Gemini Omni video survive?
Yes. The video pipeline demuxes the original audio track, processes only the video stream, and re-muxes the original audio back in unchanged. You get the same audio in the clean MP4 as the watermarked one.
What about SynthID — the invisible watermark Google embeds?
Erasio only removes the visible Gemini Omni sparkle logo. SynthID is an invisible provenance signal embedded directly into pixel values and is not removed by reverse alpha blending. If you need a tool that strips SynthID, you should know that doing so may violate Google's terms and most platforms' AI-content policies — Erasio deliberately stops at the visible mark.
Does it work for videos from Google Flow (Omni Flash)?
Yes. The Omni Flash watermark pattern that Google Flow stamps on labs.google/fx/tools/flow exports is detected automatically. Both the online tool and the Chrome extension support it, and the Chrome extension cleans Flow exports the moment you download them — zero extra clicks.
Chrome extension or online tool — which should I use?
Use the Chrome extension if you generate Gemini Omni content regularly: it cleans every download automatically and you never see a watermark in your saved files. Use the online tool for one-off cleans, files saved to other devices, or files generated before you installed the extension.
Does the Gemini Omni Watermark Remover work on mobile?
The online tool works on any modern mobile browser. The Chrome extension is desktop-only. Video processing is fastest on desktop where the WebCodecs APIs are most performant; mobile works but takes longer per clip.
Is this legal?
Erasio is a local media-processing tool — it operates on files you've already downloaded, with no unauthorized interaction with Google's servers. You are responsible for ensuring that your use of any AI-generated content complies with Google's terms, copyright law, and the upload policy of whatever platform you share it on. Don't remove watermarks from content you don't have the right to use.
Will Erasio still work when Google updates the Gemini Omni watermark?
Yes — we actively track every Gemini, Omni, Omni Flash, and Nano Banana watermark variant Google ships and update Erasio whenever the pattern changes. All updates are free; the Chrome extension auto-updates and the online tool gets new patterns server-side.
