Use Chrome or Edge
The runtime depends on WebCodecs. A current desktop Chromium browser is recommended.

Check these requirements first
Prefer H.264 MP4
Some HEVC, uncommon MOV, and legacy codecs cannot be decoded through WebCodecs.
Start with a short clip
Test a video under 100 MB first. Resolution and duration directly affect processing time.
The local video workflow
Choose the source
Add an MP4, WebM, or MOV file and let the page read its duration, dimensions, and codec.
Detect and process frames
The runtime samples the video, locates the mark, and re-encodes the processed video track locally.
Review and download
Play the original and processed versions, confirm video and audio, then download the MP4.
Video processing questions
Is the video uploaded?
No. File reading, detection, frame processing, and export run inside the current browser.
Why can an HEVC video fail?
A browser may play a codec through its media element while WebCodecs still cannot decode it frame by frame. Convert it to standard H.264 MP4.
Will the audio remain?
The runtime attempts to copy audio tracks supported by the browser and output container. Incompatible audio codecs may be skipped.
How long does a 15-second clip take?
Time varies with resolution, frame rate, device performance, and the selected restoration path. It is normally longer than playback time.
Does this remove every video watermark?
No. The runtime targets supported visible Gemini and Veo-style marks rather than arbitrary video logos or captions.
