Short form video, edited by describing it
octuedit turns long recordings into short vertical videos for Reels, YouTube Shorts and TikTok. You describe the clip you want, for example a 45 second vertical cut of the part about pricing with bold captions, and your own Claude Code or Codex finds the moment in the transcript, cuts it, reframes it to 9:16 while keeping the speaker in frame, adds captions, punch zooms and music, and keeps text clear of the app buttons. It all happens on your Mac, on a real timeline you can still adjust by hand, and octuedit costs $99 once instead of a monthly plan.

What can you ask for when making short form video?
Type the edit you want in plain words and your own Claude Code or Codex carries it out on a real timeline, which you can still adjust by hand. These requests work well for short form video; each one shows what octuedit does with it.
- “Make a 45 second vertical clip of the part about pricing, with bold captions”Finds the section in the transcript, cuts it, reframes to 9:16 and captions it.
- “Find the three best moments in this episode and make a short for each”Searches what was said and shown, then builds one vertical clip per moment.
- “Punch in on the key lines and add a beat under it”Adds zoom-ins on emphasis and a music bed cut to the beat.
- “Use the cleanest take of the intro”Finds lines said more than once and keeps the best take.
How do I turn a long video into short clips on a Mac?
On a Mac, the quickest way to turn a long video into shorts is to describe the clip you want and let an editor find and cut it. In octuedit, an AI video editor for Mac, you might ask for "a 45 second vertical clip of the part about pricing, with bold captions". Your own Claude Code or Codex finds the moment in the transcript, cuts it, reframes to 9:16 while keeping the speaker in frame, adds captions and punch zooms, and keeps text clear of the Reels, TikTok and Shorts buttons. Everything runs on your Mac on a timeline you can adjust, and you export in 1080p or 4K. OpusClip does a similar job in the browser and scores clips for virality, but it uploads your video and sells monthly plans. octuedit costs $99 once and also handles full edits, not just clips.
How does short form editing work in octuedit?
Import your recording and octuedit transcribes it on your Mac, detects shots and indexes what is said and what is on screen. When you ask for a clip, your agent searches that index by meaning, so you can ask for "the part where she explains the refund" rather than scrubbing for timecodes. It can also spot reactions and punchlines, and when a line was said twice it marks the better take.
The cut lands on a normal multi-track timeline. Reframing to 9:16 uses Apple Vision face, body and subject tracking and is written as keyframes you can nudge. Captions, zooms, music and sound effects are separate clips on the timeline, so you can ask for changes in words or drag things by hand, and undo covers the agent's edits too.
