The interaction
Edit video with AI — without giving up the cut
“Edit video with AI” too often means a gamble: a locked render you can’t change, or an eager assistant that changes things you didn’t ask for. Runs treats a request the way an editor would — as direction. You say what you want; it proposes the change on a real timeline; you decide.
Plain language
Say it the way you'd say it to an editor
Concrete requests, interpreted into concrete timeline actions.
“Make the opening quicker.”
“Let the ending breathe.”
“Remove the coffee shot.”
Each becomes a proposal — the shots it would touch, the trims it would make — that you preview and confirm. Natural-language video editing that behaves like a collaborator, not a slot machine.
The contract
The AI proposes. You hold the scissors.
Four rules, enforced by the product's structure rather than by promises.
“Start later and keep more of the pauses.”
Proposed change
- −2.1s from the opening
- +0.8s pause restored before the reveal
- Affects 2 clips · previewed in place before anything commits
A request it doesn’t understand says so, rather than quietly doing nothing. The proposal names its edits; deterministic code holds the scissors.
A request never touches the video
It is interpreted into concrete timeline actions first — which shots, which trims — and shown to you as a described proposal.
Preview before apply
You see what would change and confirm it. Nothing is applied silently, and anything applied can be undone.
Refusal over guessing
If it doesn't understand a request, it says so. A field that quietly does nothing is worse than one that answers honestly.
Every change is a version
The generated cut is never overwritten. Your changes are kept as comparisons — which is also how it learns your judgment.
Questions
Asked before applying
Can I edit a video just by typing what I want?
Yes — requests like tightening the opening, letting the ending breathe, or removing a specific shot are interpreted into timeline actions, shown as a proposal, and applied when you confirm. It is direction, not delegation: the request scope is deliberately concrete, and anything the interpreter doesn't understand it tells you instead of guessing.
Will the AI change things I didn't ask for?
No. A request becomes a visible proposal that names its actions before anything is applied, every applied change creates a version you can step back from, and the original generated cut is never overwritten.
Is this text-to-video generation?
No. Runs never generates synthetic footage. You are editing real footage you shot — the text is how you direct changes to a real timeline, not a prompt that manufactures video.
