Slow-Mo Studio
Phones record at 120 or 240 fps but often share back at normal speed — so your slow motion vanishes. This bakes the slow motion in. Pick an output frame rate, chop the timeline into chunks at real speed, half or full slow-mo, and ramp between speeds on a smooth bezier curve. It re-times your real captured frames, so it stays sharp. Everything runs in your browser — nothing is uploaded.
Slow-mo uses your real captured frames re-timed to play slowly — no invented frames, so it stays sharp. Ramps ease between speeds on a smooth bezier curve.
Monitor & timeline — source at normal speed; press Preview for slow-mo
Drag anywhere on the bar to scrub — the monitor above shows the exact frame under the playhead. Then Split to cut a chunk there, or double-click the bar to split on the spot. Click a chunk to set its speed.
Result — slowed ✓
How it works: your captured frames are re-timed so they play slowly — sharp slow-mo from your real frames, no invented ones. Ramps ease between speeds on a smooth bezier curve. Audio is dropped — slow-mo audio isn't meaningful. Output is H.264 MP4. The first render downloads the processing engine (~32 MB) and then caches it. Everything is local; your video never leaves your device. Want to trim first, or pull the audio out? Try the Video Trimmer or MP3 Extractor.
