Boomerang

Creates a boomerang effect by appending a time-reversed copy of the video to the end of the original.

video-boomerang accepts a boolean value. When set to true, the output video plays forward through the original clip, then immediately plays the same clip in reverse — creating the characteristic back-and-forth boomerang motion.

The output duration is approximately double the source clip duration. This effect is commonly used with short clips for looped social media content.

To play only in reverse without repeating forward, use video-reverse instead.
