NotebookLM Video Watermark Remover
How it works
The watermark region is masked with an FFmpeg delogo filter, then the whole clip is re-encoded to H.264. The last 2.5s ending screen can be trimmed too.
Formats MP4 → MP4 · H.264
Preserved
- Original resolution and aspect ratio
- Audio track and duration

- Bit-for-bit quality (the clip is re-encoded)
When it may not work
- Watermarks in a non-standard position or size may not be detected
- Very large videos can fail in a mobile browser
- Unusual aspect ratios may misalign the mask

NOTES / FAQ
Questions about this format
Are files uploaded to a server?
No. Every processing engine and all file data run inside your browser.
Is the watermark cut out or covered?
Neither. A delogo filter rebuilds the watermark region from surrounding pixels, then the clip is re-encoded.
Does it work on Cinematic and Short 9:16 videos?
Yes. Short 9:16 is auto-detected, and Cinematic uses its own watermark coordinates.
Is the audio kept?
Yes. Only the video is re-encoded; the audio track is preserved.
