How to Edit Your First Video With Claude Code (No Coding Experience)

What you need before you start

You need a plan, a supported computer, one short clip and some patience. Gather these first so the session itself goes smoothly.

• A plan that includes Claude Code. Anthropic’s quickstart lists Claude Pro, Max, Team or Enterprise, or a Claude Console account with prepaid API credits. The desktop app’s Code tab needs a paid subscription and asks you to upgrade if your plan does not include it.
• A supported computer. For the terminal version, Anthropic lists macOS 13.0 or later and Windows 10 version 1809 or later, plus a range of Linux distributions.
• A folder with input.mp4. Make a new, empty folder, put one vertical talking-head clip in it and rename the clip input.mp4. Keep it short for this first attempt: 15 to 30 seconds is plenty to learn on.
• Time for the first run. The setup installs tools and downloads models before it touches your video. It is the slowest part of the whole process, and you only run it once per video.

You do not need to know how to code. You will see code and commands scroll past, and you can ignore most of it. Your job is to read the permission prompts, watch the previews and write clear notes.

Install or open Claude Code

There are two ways in, and the desktop app is the gentler one. Both run the same Claude Code underneath, so the prompts on this site work in either.

The desktop app. Download the Claude desktop app for macOS or Windows from Anthropic’s Claude Code docs, install it, sign in and click the Code tab. The app includes Claude Code, so there is nothing else to install. In the row under the prompt box, choose a Local environment, click the folder control, choose Open folder… and pick the folder with your clip.

The terminal. On a Mac, press Cmd + Space, type Terminal and press Enter. On Windows, press Win + X and choose Windows PowerShell or Terminal. Paste the install command from Anthropic’s quickstart and press Enter. For macOS and Linux:

curl -fsSL https://claude.ai/install.sh | bash

For Windows PowerShell:

irm https://claude.ai/install.ps1 | iex

The installer shows no progress while it downloads, so leave the window alone until it finishes. Then open a new terminal window and check that it worked; the command prints a version number:

claude --version

Move into your folder and start a session. Replace the path with your own folder:

cd /path/to/your/folder
claude

On first use, Claude Code asks you to log in, and a browser window opens for it.

The terminal looks intimidating, but only a few rules matter. You cannot click inside it: you type, press Enter, and use the arrow keys in menus. Esc interrupts Claude mid-task. If you see command not found: claude, the install folder is not on your PATH yet, and Anthropic’s terminal guide has a short fix for each system.

Choose the model and the permission mode

Check two settings before you paste anything: the model and the permission mode. Both take seconds and save confusion later.

The model. Every prompt on this site is written for Claude Opus 5.5. On Pro, Max, Team and Enterprise plans, Claude Code already defaults to it, but confirm it. In the terminal, the current model is shown above the prompt, and typing /model opens a picker. In the desktop app, the model picker sits toward the right of the row under the prompt box. If Opus 5.5 is missing, your copy is out of date: Anthropic’s model page says Opus 5.5 needs Claude Code v2.1.280 or later and suggests running claude update to upgrade.

The permission mode. This decides whether Claude stops to ask before it acts.

• In Manual mode, Claude asks before editing files or running commands, and you answer Yes or No.
• In Auto mode, a separate classifier model checks actions in the background and blocks risky ones instead of asking you. Recent versions of the terminal app start in Auto by default.

For your first session, switch to Manual so you can see each install as it happens. In the terminal, press Shift+Tab until the status bar reads “manual mode on”. In the desktop app, choose Manual in the mode selector. Once you know what the setup normally does, Auto spares you a lot of prompts on later videos.

Run the setup prompt and approve the installs

The setup prompt turns your folder into a small editing workspace. Open the setup page, copy the prompt, replace [LANGUAGE] with the language you speak and [ACCENT COLOR] with a hex colour for highlighted caption words, then paste it into Claude Code and send it.

What follows looks busy. Claude checks for ffmpeg, creates a Python environment, installs a transcription model and a person-mask model, writes a helper file and runs everything on your clip. In Manual mode, each command arrives as a permission prompt with a short description. For this prompt, these requests are expected:

• installing ffmpeg if it is missing
• creating a Python virtual environment in your folder
• installing Python packages for transcription, masking and rendering
• running scripts on input.mp4

Choose Yes for those. If a request seems unrelated to the job, such as touching files outside your folder, choose No and ask Claude what it is for. In Auto mode you will see fewer prompts. In the terminal, an action the classifier blocks shows a notification and appears under Recently denied in /permissions, where you can retry it with a manual approval.

Then expect to wait. Downloads, transcription and a mask for every frame take a while. When a step fails, Claude can read the error output and try a fix, or switch to the fallback the setup prompt allows.

At the end, Claude exports test.mp4, the first three seconds of your clip with captions, and summarises what is ready. Play it. Check the words, their timing and the sound. If a name or a term is misspelled, ask Claude to correct it in the transcript now, because later effects start on spoken words.

Make your first edit with Digital Zoom

Digital Zoom is a sensible first effect because it needs nothing beyond the setup. It punches in towards your face on a handful of key words and adds two-colour captions.

Open the Digital Zoom prompt, copy it, and fill in two things: how many accent words Claude should choose, and your accent colour. Before you send it, add two requests at the end in your own words: list the chosen words with their times before rendering, and render a small 540×960 preview first.

The word list is your first review. Swap any word you did not actually stress when you spoke. Once you approve it, Claude writes a script, runs it and saves a preview in your folder. Open that file in any video player.

Review the preview and fix what is wrong

Good notes are specific, one at a time and about what you can see. Watch the preview at least twice: once for the zooms, once for the captions. Then write the kind of note you would give a human editor:

• “The third zoom is too strong; make it gentler.”
• “Captions sit on my chin during close shots; move them lower.”
• “Drop the zoom on ‘really’.”

One change per message makes it obvious what each note did. For more on wording, see how to write a video prompt for Claude.

When something goes wrong, you have three tools:

• Stop and steer. Press Esc in the terminal, or the stop button in the app, then type a correction. You can also type a correction while Claude works, and it adjusts before its next step.
• Rewind. In the terminal, /rewind, or Esc twice on an empty prompt, opens a menu that restores files Claude changed with its editing tools. It does not undo files made by shell commands, and a rendered MP4 is one of those. Ask Claude to save each render under a new name, such as preview_v2.mp4, and never to overwrite input.mp4.
• Ask before fixing. “Why did the zoom drift left at 0:12?” lets Claude inspect the frames at that moment before it changes anything.

When the preview looks right, ask for the full-resolution render. Once you have a few effects working, the combine and fix workflow puts several on one timeline and saves your setup as a reusable skill.
