Change the timing of the actual downloaded clip. Select a playback multiplier, preview the movement and export a file with the new duration.

Video output is re-encoded WebM, up to 1920 px on the longest edge. Frame output is PNG, up to 3840 px. Input codecs depend on your browser. Video export uses real-time recording and is not lossless.

2× speed; full source range
The 4.46-second source becomes approximately 2.28 seconds. The browser requests pitch preservation.
The source was generated with MiniMax H3; this edit uses browser canvas and recording, with no AI credits. Re-encoding can change compression detail. Source generation record
Slow motion repeats existing frames and cannot recover motion detail that was never recorded. A 0.5× export takes about twice the original running time. The browser preserves audio pitch where supported, but extreme multipliers can sound rough. This is a constant speed change across the whole clip, not a speed ramp.
Choose a supported speed from one-quarter speed to four times speed. For a selected source range of four seconds, two-times speed requests roughly two seconds of output; half speed requests roughly eight. Recording introduces small timing differences, so inspect the download rather than using the multiplier as a frame-exact duration promise. The sixty-second limit applies to the selected source range.
The video speed changer changes playback speed while recording the new clip. The browser is asked to preserve audio pitch, but audio quality and timing depend on its implementation. Listen for clipped words and inspect fast movements before sharing. Slowing a low-frame-rate source cannot create genuinely captured intermediate motion; this is not an AI frame-interpolation tool.
A faster product reveal can fit a short post, while a slower movement can make a detail easier to inspect. Start with a moderate factor, preview and compare with the original. Exporting another version uses the same local source and no generation credits. The output is WebM; this video speed changer does not promise a particular social platform will accept that format without a separate conversion.
| Use case | Setting | Expected result |
|---|---|---|
| Slow a movement | 0.5× | Approximately twice the duration |
| Shorten a demo | 2× | Approximately half the duration |
| Keep timing | 1× | Original running time |
It stretches time using the available frames; it does not synthesize new intermediate frames. For smoother slow motion, start with footage recorded at a higher frame rate.
