Conas a Oibríonn sé

Joins several video clips into one MP4, in the order you choose, with the FFmpeg engine running in your browser. Clips of different sizes or shapes are fitted into one frame with black bars instead of being stretched or cropped.

  1. 1
    Add and order your clips
    Drop in MP4, MOV, WebM or MKV files, then drag them or use the up/down arrows to set the order. Tap a thumbnail to preview a clip.
  2. 2
    Each clip is checked
    FFmpeg (WebAssembly, ~31 MB, downloaded once and cached) reads every clip's codec, frame size, frame rate and audio format. Nothing is uploaded.
  3. 3
    Matching clips are joined as-is
    When every clip shares the same codec, size, frame rate and audio (e.g. several clips from one phone), they are joined by stream copy with FFmpeg's concat demuxer — no re-encoding and no quality loss.
  4. 4
    Mixed clips are re-encoded to one frame
    Otherwise each clip is scaled to fit the output size (same as the first clip, 1080p or 720p), padded with black bars, set to one frame rate and encoded to H.264 with AAC audio. Clips without sound get silence so the audio stays in sync.

Your videos are read directly from your device by the in-browser engine and the merged MP4 is built in memory. No clip is ever uploaded to a server.
