À quoi convient le video trimmer ?
Video trimming exports a short clip from a local video. After the user enters a start time and duration, the tool calls ffmpeg.wasm in the browser and exports MP4.
The first version uses lightweight inputs instead of a full timeline. Keep the original file and preview the result before downloading.
Formats pris en charge : MP4, MOV, WebM, AVI ; limite de fichier unique : 500MB.
