Output: WebM (recorded)

Status: Idle

Note

This cutter records the selected segment via the browser (uses captureStream() & MediaRecorder). The output will be a .webm file. Works best in modern Chrome / Edge / Firefox. Mobile browsers may vary.

Tips:

• Set start slightly earlier if you want a precise frame (seeking precision depends on codec).
• Long cuts will take time and produce large files.
• If your browser doesn't support captureStream, try Chrome/Edge desktop or recent mobile Chrome.

This tool runs entirely in the browser and does not upload videos anywhere.

Built for quick trims — recorded segments saved as WebM. Test with short clips first.
