Edit video by describing the change

Trim by quoting the transcript, cut silence, reframe for vertical, and burn in captions — every edit arrives as a proposal you accept or reject.

Last updated Jul 23, 2026

Some edits don't need a timeline — they need a sentence. Tell Astrono what to change in a video, and it comes back with a concrete proposal you can accept or reject. Your originals are never touched; approved edits are exported as new files.

Edits you can ask for

  • Trim or cut a section by quoting the transcript
  • Remove silence across a recording
  • Reframe to 16:9, 9:16, 1:1, or 4:5, with optional subject tracking
  • Burn in captions generated from the transcript
  • Set output resolution — 720p, 1080p, or source

Cut by transcript quote

Because indexing gives every video a word-level transcript, you can point at footage with words: "cut from 'let's talk about pricing' to 'moving on'" or "trim everything before 'welcome back.'" Astrono finds those exact lines and cuts there — no scrubbing for the in-point. This works on indexed videos; see how AI indexing works.

Reframe with subject tracking

Ask for a new aspect ratio — 16:9, 9:16, 1:1, or 4:5 — and optionally turn on subject tracking, which keeps the subject in frame as the crop moves. That's the difference between a static center-crop and a vertical cut that actually follows the speaker.

Captions and resolution

Ask for burned-in captions and Astrono generates them from the transcript, permanently rendered into the output — ready for feeds where most viewers watch muted. Choose the resolution for each export: 720p, 1080p, or match the source.

Review proposals, then export

Every edit is a proposal. Astrono shows you what it intends to do, and nothing is applied until you accept; reject anything that misses. When you export, the result is saved as a new file — your original is never overwritten, so you can always go back to the master and cut it differently.

Export costs

Exporting costs 0.5 AI minutes per output minute — a 4-minute cut costs 2 AI minutes. Requesting edits and reviewing proposals in chat is free, like all conversation with Astrono.
