video frame capture는 무엇에 적합합니까?
Video frame capture extracts a cover image, preview image, or material frame from a local video. The tool reads a selected timestamp and exports JPG or PNG with ffmpeg.wasm.
The first version uses a time input rather than a frame-by-frame picker. If the timestamp is beyond the video length, processing may fail.
지원되는 형식: MP4, MOV, WebM, AVI; 단일 파일 제한: 500MB.
