See what the tool changes.

A real example: the after side is the unedited output of a KinoPipe job. Run the live form above to generate the same result from your own media.

FAQ

About boomerang

Why is the source limited to 30 seconds?

Reversing buffers every frame in memory. Trim first with trim-video for longer sources; boomerangs work best under a few seconds anyway.

Is the audio kept?

No. Boomerangs are delivered silent, like the native Instagram format; add music afterwards with add-music-to-video.
