AI 動画透かし削除ツール
切り抜きやぼかしよりも、AI は動く透かし、字幕、タイムスタンプ、ロゴを自然に処理しやすい方法です。
- Visible watermark: the "Gemini" text or logo rendered in the corner of AI-generated video frames, similar to a channel bug or platform branding overlay.
- Invisible watermark (SynthID): according to Google DeepMind, an imperceptible digital watermark embedded into the video pixel data to identify AI-generated content. It cannot be seen by the human eye and is designed to survive compression, cropping, and basic editing — it requires specialized detection tools.
- The visible Gemini logo is functionally identical to other corner watermarks — it can be removed with AI inpainting just like a TikTok or YouTube overlay.
- SynthID is a separate technology from the visible logo. This tool addresses the visible watermark only and does not modify SynthID data.

AI detects and removes the Gemini watermark
The AI scans every frame, locates the visible "Gemini" text or logo watermark in the corner, and reconstructs the covered pixels using the surrounding background. No manual selection needed for fixed-position watermarks.
Preview and download the clean export
Compare the cleaned clip against the original. Check the area where the Gemini logo was — especially around motion edges and textured backgrounds — then download the watermark-free export at your original resolution.
Gemini video watermark removal results
See how AI inpainting removes the visible Gemini text and logo from Google Gemini-generated videos without cropping the frame or leaving a visible blur patch. The background is reconstructed pixel by pixel.
- No blur or smudgeAI reconstructs the scene behind the Gemini logo, filling in the area with matching detail and texture.
- Full frame preservedNo cropping needed — the entire video frame stays intact at the original resolution Gemini exported.
- Works on Gemini 1.5, 2.0, and newerThe visible watermark position and style may differ between Gemini versions, but the AI adapts to each layout automatically.

- Team or business contentGemini-generated clips produced under your organization's Google Workspace or Google Cloud account.
- Client-approved editsVideos where the content owner gave explicit approval for watermark removal before publishing.
- Portfolio cleanupRemoving the Gemini logo from your own demo reel, portfolio, or client presentation of AI-generated work.
Gemini 2.0 watermark removal in action
See the AI inpainting result on a Gemini 2.0 generated clip. The visible "Gemini" branding in the corner is detected and erased frame by frame, with the background reconstructed to match the surrounding scene.
- Frame-accurate cleanupEvery frame is processed individually — no ghosting or temporal artifacts around the removed watermark area.
- Original resolution preservedThe output stays at the same resolution and frame rate as the Gemini export — no re-encoding quality loss.
- Works across Gemini versionsCompatible with Gemini 1.5 Flash, Gemini 2.0, and newer model watermark styles and positions.

- Professional presentations: Remove the Gemini branding from AI-generated clips used in client pitches, investor decks, or corporate videos where clean output is expected.
- Ad creative production: AI-generated video used in paid advertising or marketing materials typically requires a clean, unbranded version for platform compliance.
- Portfolio and demo reels: Showcase your AI video work without the platform watermark, keeping the focus on the content quality and your creative direction.
- Multi-tool workflows: When Gemini-generated clips are combined with footage from other sources in a larger production, the Gemini logo creates visual inconsistency across cuts.

How do I remove the Gemini watermark from my video?
Upload your Gemini-generated video to UnmarkAI. The AI detects the visible Gemini logo in each frame, erases it using inpainting, and reconstructs the background. Preview the result side-by-side, then download the clean version.
Does this remove the visible Gemini logo or the invisible SynthID watermark?
This tool removes the visible "Gemini" text and logo watermark that appears in the corner of AI-generated video frames. SynthID is Google's invisible, imperceptible watermark embedded in the pixel data by Google DeepMind — it cannot be seen by the human eye, requires specialized detection tools, and is designed to remain detectable even after compression, cropping, and basic editing. The two serve different purposes: the visible logo identifies the generation tool to human viewers, while SynthID enables automated AI content detection for provenance tracking. This tool addresses only the visible watermark and does not modify SynthID data. (Google DeepMind SynthID announcement)
Does this work on Gemini 2.0 videos?
Yes. The visible watermark layout may differ slightly between Gemini 1.5, Gemini 2.0, and newer versions — the logo position, size, or transparency can change — but the AI adapts to each layout automatically. Upload your video directly and the tool handles detection.
