    MP4, MOV, MKV, WebM, AVI, WMV, FLV, 3GP, MPEG, TS/MTS and more; up to 2 GB. Effects re-encode the video, up to about 25 minutes of 1080p (longer for smaller videos); removing the sound copies it, for videos up to 3 hours.

    Options

    Kept in step with the picture and at its normal pitch (no chipmunk voices).

    0 leaves it unchanged; positive values brighten, negative values darken.

    100 leaves it unchanged.

    100 leaves it unchanged; 0 is black and white, 150 gives stronger colours.

    From black at the start; the sound fades in with it. 0 = no fade.

    To black at the end; the sound fades out with it. 0 = no fade.

    Your files are deleted after processing.

    A boomerang plays a short clip forwards and then backwards, so the movement bounces back to where it started: a toast that clinks and unclinks, a jump that lands and lifts off again, hair that flips and settles. Because it ends on its first frame, it loops without a jump.

    How to make a boomerang video

    1. Upload a short clip (MP4, MOV, MKV, WebM, AVI, WMV, MPEG, TS and more), up to 60 seconds long.
    2. Effect: Boomerang is already chosen.
    3. Start, and download the boomerang.

    What you get

    • Forwards, then backwards: the result is twice as long as the clip. The frame where it turns is shown once, so the bounce doesn't stutter.
    • No sound: sound played backwards rarely fits, so a boomerang is silent.
    • Full size and frame rate: nothing is shrunk or dropped. Upright phone videos stay upright.
    • Format: MP4, MOV, MKV and WebM stay in their format; other formats become MP4. The video is re-encoded at high quality.

    Tips for a good boomerang

    • Keep it short. The best boomerangs start from one to three seconds of a single movement. Cut that moment out of a longer video first with the video trimmer: clips longer than 60 seconds are refused.
    • Keep the camera still. The movement of the subject then reads clearly both ways.
    • Speed it up. Boomerangs usually play fast. Upload the result again and choose Change the speed at 1.5× or 2×.
    • Repeat it. Websites and players can loop a video by themselves; for a file that plays the bounce several times, upload the result again and choose Loop.
    • As an animation: to share the boomerang as a GIF or animated WebP, make it here first, then use Video to GIF.
