What does the Ease slider do?

It slows the clip into each turnaround and speeds it back up afterwards, so the direction change looks fluid instead of snapping. 0 is a hard ping-pong; 1 is the softest turnaround.

Does the boomerang keep the audio?

No — the backward half cannot play meaningful audio, so the output is exported silent.

How do I get a looping GIF instead of an MP4?

Use "Or convert to GIF" under the Create button — GIFs loop by default, which suits a boomerang perfectly.

Make a Boomerang Video Online

Turn a short clip into a boomerang: it plays forward, then backwards, ready to loop forever. The Ease slider softens the turnarounds — at 0 the motion ping-pongs hard, higher values slow gracefully into the reversal and accelerate back out. Everything runs locally in your browser using WebCodecs — your file is never uploaded to a server, so it stays private and conversion starts instantly. Need more than one operation? Use the "Continue this clip in" links in the workspace — your edits carry over to crop, trim, resize and compress without re-uploading the file.
