Speed Change — Slow Motion & Speed Ramps Free, In Your Browser
Slow a moment down, speed a jump cut, or drop a Hero / Bullet / Montage ramp — compare against the original and download at full quality. Free, in your browser.
A quick tool — one slice of free Studio. The same job (and the rest of the edit) lives on the board: multi-track, captions, color, sound, stock. Connect your AI and it edits for you.

Eziclip Speed change retimes a clip right in your browser: pick a constant rate from 0.25× to 4×, or apply a CapCut-like curve preset (Hero, Bullet, Montage), then download the result. Slow-mo uses on-device smooth frame synthesis so motion stays fluid. Unlike CapCut, VEED and Kapwing cloud editors, nothing leaves your machine.
Change video speed in seconds
Speed is one of the fastest ways to reshape pacing — stretch a reveal into slow motion, compress filler, or pulse a clip with a ramp. Eziclip does it as a focused quick tool: drop a file, pick a rate or curve, download the MP4.
Constant rates cover everyday slow-mo and speed-up. Curve presets mirror familiar CapCut shapes — a soft Hero dip, a Bullet hold, or Montage alternation — baked through the same renderer Studio uses.
Smooth slow motion in your browser
When you slow below 1×, Eziclip synthesises intermediate frames on-device so the picture stays fluid instead of stuttering on every source frame. The bake uses the same compositor path as Studio preview and export.
Audio retimes with the picture. Free exports carry a small corner mark; Plus removes it across every tool.
Rates and CapCut-style curves
Use 0.25×, 0.5×, 1×, 2× or 4× for a uniform retime. Or pick Hero, Bullet or Montage when you want a ready-made ramp without drawing keyframes.
Compare Original against the speed-changed result before you export, and re-run at another preset any time — your source file is never overwritten.
Runs in your browser, free
Processing stays on your device — no account and no upload to retiming servers. Built for short clips (about two minutes works best).
When you need keyframed ramps on a full timeline, the same Speed controls live in Studio.

CapCut-style speed curves: Hero dips into slow-mo in the middle, Bullet holds a slow stretch between fast ends, Montage alternates fast and slow. They bake as a finished MP4.
This quick tool covers constant rates and the three curve presets. For freehand speed keyframes on a timeline, use Studio Speed.
