The build spec · for Claude Code · by Winson

Stop paying an editor every time you post.

Drag one PDF into Claude Code. It installs four free tools and builds your own AI video editor — the one I use for my 90-day Reels challenge. On your computer. $0 per video.

The problem

Editing is the tax on every video.

Posting every day means editing every day. You either pay someone per video, forever — or you lose your evenings to a timeline. I priced it out before I started my challenge:

the cheapest editor I found
$15

per video. The good ones quoted $50, $60, $100 — per minute of video.

$15 × 90 videos
$1,350

for one 90-day challenge at the cheapest price. Plus waiting days for every revision.

$1,350 $0

per video after setup. It renders on your own computer. You pay once for the spec.

Real output, not mockups

Edited by this system.

Frames from my own Reels. The cuts, captions, graphics, sound and checks were all done by Claude following the rules in this spec. I directed; I didn't open an editing app.

How it works

Drag. Paste. Direct.

1

Drag the PDF into Claude Code

Open an empty folder in Claude Code and drop the file in. Claude reads PDFs directly.

2

Paste one prompt

It's on page 2. Claude installs the tools (asking before each one), builds the workspace, interviews you for your brand, and writes five editing skills.

3

Talk to it like an editor

Drop your clips in a folder and say what you want. It cuts, adds graphics and captions, checks its own work, and exports.

“Edit the clips in projects/morning-routine/raw into a 40-second Reel. Hook first. Stamp the tool names above my head when I say them.”
What's inside · 19 pages

Everything Claude needs. Nothing you have to remember.

  1. 01The one prompt — paste it and Claude builds the whole system in order.
  2. 03The stack & install — native on Windows and Mac, with the GPU checks that actually work.
  3. 04The workspace — your taste on top, one folder per video below.
  4. 05Your brand & style file — colours, fonts, caption voice, and how to copy a Reel's style without copying the Reel.
  5. 06Skill 1 · rough cut — word-level cuts that land on the breath, not on the word.
  6. 07Skill 2 · graphics in Remotion — what earns a graphic, safe zones, and the render rules nobody tells you.
  7. 08Skill 3 · picture — reframes, screen recordings, B-roll, and the colour trap that turns faces red.
  8. 09Skill 4 · sound & captions — clean voice, music that sits under it, captions that never lie.
  9. 10Skill 5 · deliver & prove it — six automatic checks before you ever press play.
  10. 11The truth rules — your editor never invents a number or fakes a proof shot.
  11. 12Give it eyes — the review loop that catches its own mistakes.
  12. 13Parallel agents — how a Reel goes from an afternoon to under an hour.
  13. 14Your first edit — a self-test on your own clip, and how to direct it.

Questions

Before you buy.

Do I need to know how to code?

No. I'm not a coder. You never open the code — Claude writes and runs it. You describe what you want in plain words, like you'd brief a human editor.

Do I need to know video editing?

No. You need taste — knowing what you like. The spec carries the editing rules (where to cut, what earns a graphic, safe zones, sound levels) so Claude applies them for you.

What do I need to run it?

Claude Code, which needs a paid Claude plan (the free chat can't install software). A Windows 10/11 PC or a Mac with about 15 GB free. An NVIDIA graphics card is optional — it makes transcription much faster, but everything works without one.

Does it work on Mac?

Yes. The spec has install steps for both. Mine runs on Windows natively — no Linux or WSL needed.

What does it cost after I buy it?

Every tool in the stack is free and open-source, and rendering happens on your own computer. Your only ongoing cost is your Claude plan. AI-generated B-roll is optional; if you connect an image service, the spec makes Claude quote the cost and wait for your yes first.

Will my videos look like yours?

No — they'll look like yours. Claude interviews you for your colours, fonts and caption style, and you can teach it a style from any reference Reel. The spec copies how good edits are built, not anyone's look.

Is this a course?

No videos to watch. It's a build spec: a PDF written for Claude, so the AI does the setup and follows the rules on every edit. You read the parts you're curious about.

Does it actually work?

Every frame in the "Edited by this system" section above is from my real Reels. Results depend on your footage and on Claude, so you'll still direct and approve — but the spec is built to get you a first draft you'd actually post.

I'm Winson. I'm posting a Reel a day for 90 days and I edit every one with this system — WhisperX, Remotion, FFmpeg and Python, directed through Claude. This is the spec I wish I'd had on day one.
