Frequently Asked Questions
What is a boomerang video?
A short clip that plays forward and then immediately backward, creating a seamless back-and-forth loop — the effect Instagram popularized.
How long should my clip be?
Keep it short, ideally 1–4 seconds. The reverse pass holds every frame in memory, so long clips can be slow or run out of memory in the browser.
Why is there no sound?
Boomerangs are silent by design — reversed audio sounds odd, so the audio track is dropped.
Does it upload my video?
No. The boomerang is built locally in your browser with FFmpeg WebAssembly.
