Highlight cut
Pick the strongest segments up to a target length — a 60-second cut from a long take.
Prompt-native video editing
A mass-market, enterprise-shaped video editor with an AI Director at the spine. You talk; it edits your real footage into a posted-ready video — every step visible, every step editable. Zero timeline knowledge required.
Everything below is real today
Ask for any of these in plain language — or chain several in a single request. The Director plans the steps, shows you the result on your own media, and leaves every choice editable.
Pick the strongest segments up to a target length — a 60-second cut from a long take.
Tighten a talking-head video by dropping filler words and dead air.
9:16, 1:1, 4:5 or 16:9 — every clip re-anchors so nothing important leaves the frame.
Ramp speed for energy and add a scale-pulse punch-in to land the emphasis.
Warm, cool, vivid, cinematic, vintage, noir and more — applied on your real footage as you watch.
Generated from the transcript, synced through the cuts, auto-fit to the frame with a readable pill.
Static and kinetic title cards with fade in/out, plus fade from and to black.
Overlay picture-in-picture b-roll in any corner, and punch in to highlight a moment.
Turn a set of photos into a video with Ken Burns moves and crossfades — then treat it like any edit.
Layer clips and images over your main track, corner-anchored, sized to taste.
Lanczos scale, unsharp and denoise up to 3840×2160 — never alters faces or content.
Real .mp4 renders on export with ffmpeg (bundled in Docker).
How it works
The flow is the same whether you are trimming a keynote or building a slideshow from a folder of photos.
Drop in a video, a set of photos, or an audio track. Cadence probes it in the browser — no upload round-trip.
Say it plainly: “cut a 60s highlight, make it vertical with captions, cinematic look.” The Director plans and calls the tools.
Watch it play on your real footage with looks, motion and captions live. Adjust anything — the edit-doc is yours to tweak.
Render a faithful .mp4 with ffmpeg, or export the edit-doc JSON and hand the recipe to any renderer.

Questions
Yes — it is free-first and runs locally by default. The Director, live preview and editing tools use deterministic, offline defaults with no API keys required. Optional AI super-resolution is off by default and the only piece that can be metered; you opt into it explicitly.
No. The faithful upscale (Lanczos scale, unsharp, denoise) is contract-enforced to never alter faces, identity or content — it sharpens what is already there rather than inventing detail. Even the optional AI super-resolution providers are identity-preserving by contract.
Not to edit and preview — that all runs in your browser on your real media. To render a final .mp4 you need ffmpeg, which is baked into the Docker image (so docker compose up just works). On your own machine, point FFMPEG_PATH at any ffmpeg binary. You can always export the edit-doc JSON without installing anything.
Cadence is local-first. Your footage is probed and previewed directly in the browser — there is no upload round-trip to watch your edit come together. Signing in provisions a personal workspace so projects can be saved, but the editing itself stays on your machine.
No. You describe the edit in plain language and the Director turns it into a declarative edit-doc — the single source of truth. There is a cuts timeline you can click through if you want it, but nothing about the flow requires it.
