video trimmer는 무엇에 적합합니까?
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.
지원되는 형식: MP4, MOV, WebM, AVI; 단일 파일 제한: 500MB.
