Choose a short video to turn into a boomerang
Your video stays in this browser tab. Nothing is uploaded. Device-aware file limit: 100 MB.
A boomerang video maker turns a short clip into a back-and-forth loop by playing the action forward and then in reverse. Trim the best moment, choose its speed and cycle count, then export an MP4. Processing happens in your browser, with no upload, account, or watermark.
Drop an MP4, MOV, WebM, MKV, AVI, or another common video file into the maker.
Set start and end times for a segment between 0.25 and 8 seconds, then preview that selection.
Adjust playback speed, select one to three cycles, and decide whether to mute or reverse the audio.
Run the local video engine, preview the repeating result, and save the MP4 to your device.
This editor uses a WebAssembly build of FFmpeg to trim the chosen moment, decode it, reverse the frames, and join both directions into one H.264 MP4. You can place one, two, or three complete forward-reverse cycles in the downloaded file.
Silent output is the default because speech and music often sound distracting backward. If the source has audio, the optional ping-pong mode keeps its timing aligned by reversing the second half along with the picture.
No. The selected video stays in a local browser file object and is processed in this tab. The FFmpeg engine files download from a public CDN on first use, but your source and finished MP4 are not sent with that request or stored in a CanDoYa account.
Yes. You can trim, process, preview, and download a boomerang MP4 without signing up, paying for credits, or adding a CanDoYa watermark. Practical limits come from browser memory and processing speed, especially on phones and lower-memory devices.
The selected segment can be from 0.25 to 8 seconds, even if the source video is longer. A boomerang doubles that segment because it includes both directions, then multiplies it by the chosen cycle count. Short clips process faster and usually create the strongest visual rhythm.
Choose the saved video, enter the start and end times for the action you want, and preview the selection. Pick a speed and cycle count, then create the MP4. The tool automatically appends the reversed frames, so you do not need to duplicate or edit tracks manually.
It can. Silent output is selected by default because reversed voices and music can sound awkward. Choose Forward + reverse audio to keep the source audio on the forward half and play it backward on the return. If the source has no audio track, the result stays silent.
A normal loop repeats the complete clip from its last frame back to its first, which can create a visible jump. A boomerang follows the forward clip with the same motion in reverse, so the picture returns to its starting position before the next play begins.
The picker accepts common files such as MP4, MOV, WebM, MKV, AVI, MPEG, and MTS. The browser preview supports fewer codec combinations than FFmpeg, so an uncommon source may show no preview but still export. Every successful result downloads as an H.264 MP4.
FFmpeg must decode and hold the selected frames so it can emit them in reverse, then encode a new MP4. Higher resolution, longer selections, more cycles, and high quality increase the work. Keep the tab open and use a short segment for quicker results.
