Edit your videos with Claude Code or Codex

What it does

• Cuts like an editor. Every pause goes, every “um” goes, and when you restart a line it keeps your last clean take. Each cut is checked against the actual audio, so it never clips a word.
• Captions that get names right. Word-timed captions with the spoken word highlighted. A built-in word list fixes what transcription gets wrong (“Cloud Code” becomes “Claude Code”), and you can add your own names.
• Finds real B-roll. For every feature or tool you mention, Claude looks for the real thing: official demo clips, product pages and docs. When nothing exists, it rebuilds the app’s interface so it looks like a screen recording.
• 46 effects, ready to use. Text behind your head, kinetic hooks, magazine covers, sticker cut-outs, chat-app recreations, follow and comment cards and more. Browse them with previews and pick with one click.
• Shows you the plan first. You get a storyboard of every section and effect. Nothing renders until you say yes.
• Checks its own work. It can’t watch the video, so it measures it: frame sheets, safe zones, loudness, and a check for any phrase said twice.

What you need

• A Claude Pro or Max plan (Claude Code isn’t on the free plan), or a ChatGPT plan that includes Codex.
• A Windows or Mac computer with about 2 GB free.
• A vertical video of you talking to camera. Film in 1080p or 4K if you can.

Everything else is free: ffmpeg, Node.js, Python and HyperFrames (the open-source tool that turns Claude’s designs into video). You don’t need CapCut, Premiere or DaVinci Resolve.

Set it up in 15 minutes

1. Download the kit and unzip it into a plain folder, for example C:\Video on Windows or ~/Video on Mac. Not your Desktop or Documents if they sync to OneDrive or iCloud: sync apps lock files while videos render.
2. Open Claude Code in that folder. In the Claude desktop app, open the Code tab and choose the folder. In Codex, open the folder the same way.
3. Paste the install prompt (below). Claude copies the editor into your skills folder, checks your computer and tells you what’s missing in plain words. It asks before installing anything.
4. When the check says “All set”, you’re ready.

Install the AI Impact Editor for me. The kit is in this folder.

1. Copy the ai-impact-editor folder into my skills folder: ~/.claude/skills/ for Claude Code, or ~/.agents/skills/ for Codex.
2. Run: python ai-impact-editor/tools/check_setup.py  (python3 on Mac)
3. For every [FIX] line, tell me in one sentence what it is and the command that fixes it. Ask me before you install anything, then install the ones I say yes to.
4. In Claude Code, also install HyperFrames: /plugin marketplace add heygen-com/hyperframes then /plugin install hyperframes@hyperframes
5. Run the check again and show me the result.

The first time you transcribe, it downloads a free speech model (a few hundred MB). That’s normal and only happens once.

Edit your first video

1. Put your video in the folder and tell Claude: Edit C:\Video\raw.mp4 (or describe the feel: Edit raw.mp4, make it feel calm and premium).
2. Check the cut. Claude lists what it removed: pauses, fillers and restarted lines. Anything it’s unsure about, it asks.
3. Approve the storyboard. A table of each section, the line you say and the effect that goes there. Change anything you like.
4. Wait for the render. About 10 to 15 minutes for a 90-second reel on a normal laptop. Every version gets a new number, so nothing is overwritten.
5. Give notes like you would to an editor. “Bigger hook”, “less in the middle”, “cut the line at 1:13”. It fixes them and renders the next version.

46 effects, with previews

Say Show me the effects and the kit opens a page of every effect playing on real footage. Hover to preview, click to add, or pick a style preset, then copy the prompt it builds for you.

• Text behind your head FX01

  A big word sits behind you, with your head in front of it.

• Kinetic hook HK01

  Three fast text beats in the first two seconds.

• Claude Code recreation UI01

  The real Claude Code app, with edits and replies typing out.

• ChatGPT recreation UI04

  A prompt types in and the answer streams back.

• Magazine cover FX02

  You on the cover, with the title behind your head.

• Comment keyword CTA CT01

  The comment types your keyword and a reply pops up.

• Lo-fi phone: quick iPhone videos with light graphics.
• Studio: tool and news explainers, with real product footage on most beats.
• Showcase: a signature effect every few beats.

Why the edits look professional

• It researches every beat. Name a feature and Claude looks for the company’s own demo, product page or docs and uses that, the way a human editor would.
• Realistic UI, not clip art. When there’s no footage, it rebuilds the real interface (Claude, ChatGPT, a terminal, a phone app) from reference screenshots.
• A visual change every few seconds. Pages, pop-ups, punch-ins and transitions rotate, so no layout repeats twice in a row.
• Real proof only. Recreated screens show how a product works. It never invents a result, a stat, a review or a social post.

What it costs

The software in the kit is free and runs on your computer. The only cost is your AI plan. Claude Pro is enough for a few videos a week; if you edit every day, Max gives you more room. Editing uses a fair share of your usage because Claude looks at frames and renders drafts, so give all your notes in one message and start a new chat for each video.
