video muterは何に適していますか?
Video muting removes the audio track from a local video and creates an MP4 with picture only. It is useful for removing ambient sound, background music, or private speech.
The tool processes files with ffmpeg.wasm in a browser Worker, so files are not uploaded. Output is re-encoded as MP4 for compatibility.
サポートされている形式: MP4, MOV, WebM, AVI;単一ファイルの制限: 500MB。

Will muting affect picture quality?
The first version re-encodes video for compatible output, so quality should remain close to the source.

The first version exports MP4 to prioritize browser playback compatibility.
