Draw speed curves, AI slow motion, beat sync, and 4K export — all in the browser. Your footage never leaves your machine. Free to start, no installs required.
I built Rampcut because every speed-ramp tool I tried made me choose between "good curve control" and "doesn't force me to upload my footage to some server first.
The core idea: do the actual video processing in the browser, so nothing leaves your machine and there's no upload wait before you can start editing. From there it grew — AI-assisted slow motion so ramps look natural instead of choppy, beat sync so cuts land on the music automatically, and 4K export without a render farm.
It's free to start, no installs. Would love feedback on what's missing — especially from anyone doing a lot of speed-ramp or music-sync edits.
