How I Turn One Video Into Three Social Posts (Using Claude)

If you've ever recorded a video for your business and thought, "I really should do something with that," this is for you. One transcript. Three posts. About five minutes of your time.

Get the Transcript First

Before any of this works, you need the raw text of your video. If your video is on YouTube, there's a free Chrome extension called YouTube Summary with ChatGPT and Claude. Install it, open any of your YouTube videos, and a panel appears on the right that automatically generates the full transcript. Copy it.

That's your starting point.

If your content lives elsewhere, a Zoom recording, a webinar, or a voice note, most AI tools will transcribe audio files directly. Either way, take two minutes to scan the transcript before you use it. Fix any obvious errors. Check that names, website addresses, and any figures are accurate. Garbage in, garbage out.

Why Your Prompt Matters More Than the AI You Use

Whether you're working in Claude, ChatGPT, Gemini, or Copilot, the quality of what you get back depends almost entirely on what you put in. Most people paste a transcript and type, "write me a LinkedIn post." The AI complies. What comes back is passable and generic, technically correct, but it doesn't sound like you, and it won't resonate with your audience.

The fix isn't a better AI tool. It's a better prompt.

The SIGNAL Framework

SIGNAL is the prompting method I use every time I repurpose content. Here's how it works for turning a transcript into social posts.

S — Set the goal. Tell the AI exactly what you want it to produce. In this case: three social media posts, one for LinkedIn, one for Facebook, one for Instagram.

I — Give the instruction. Specify what each post should look like for LinkedIn: professional tone, first person, 150 words maximum. For Facebook: conversational, 100 words maximum, end with a question. For Instagram: caption plus five hashtags only.

G — Add context. Tell it who your audience is. Mine is small business owners in Ireland and the UK, not marketing professionals. The AI needs to know who it's writing for, or it'll write for everyone, which means it'll connect with no one.

N — Note the format. Tell it exactly how you want the output presented. I ask for each post under a clear heading, with no commentary or explanation between them. Just the posts, ready to copy.

A — Ask for reasoning. After the three posts, I ask the AI to add a short note on what it changed between each version and why. This helps me understand whether the decisions it made match my own judgement, and where I might want to push back.

L — Loop and refine. This is the step most people skip. If the first draft isn't right, don't start again. Ask the AI to review a specific section and improve it. Tell it what didn't land. Nine times out of ten, the revised version is meaningfully better than accepting the first answer

What You'll Have at the End

Three posts, formatted and ready. Each one is adapted for its platform. The LinkedIn version professional and direct. The Facebook version conversational with a hook for comments. The Instagram version tight, with relevant hashtags.

Go through each one before you publish. Check the tone sounds like you. Verify anything factual. Make sure your website or any links mentioned are correct. The AI drafts. You edit and approve. That's the workflow.

Your Content Library Is Bigger Than You Think

Most business owners underestimate how much usable content they already have. Old YouTube videos. Webinar recordings. Podcast episodes. FAQs you answer on client calls every single week. Any of it can be turned into social content in minutes once you have a structured prompting method.

You don't need to create more content. You need to extract more value from what already exists.

The SIGNAL framework is available as a free PDF on the AI resources page. No email required, click download, and it's yours.

Start with one video you recorded in the last six months. Run it through the process. See what you get.

FAQ's

Q1: How do I get a transcript from my YouTube video?

A: Install the free Chrome extension "YouTube Summary with ChatGPT and Claude." Open your video and a panel appears on the right, generating the full transcript automatically. For Zoom recordings, webinars, or voice notes, most AI tools will transcribe audio files directly. Either way, scan the text first and fix any obvious errors before you use it.

Q2: Why do AI tools produce generic social media posts from my content?

A: The problem is usually the prompt, not the AI tool. Pasting a transcript and asking for "a LinkedIn post" gives the AI almost nothing to work with — it doesn't know your audience, your tone, or how long the post should be. A structured prompt with clear instructions consistently produces more useful results.

Q3: What is the SIGNAL framework for repurposing video content?

A: SIGNAL is a six-step prompting method: Set the goal, give the Instruction, add context about your audience, Note the format you want, Ask for reasoning behind the choices, then Loop back to refine anything that didn't land. It takes around five minutes and produces three platform-ready posts from a single transcript.

Q4: What format should I ask for when creating posts for different social platforms?

A: Be specific about each one. LinkedIn: professional tone, first person, around 150 words. Facebook: conversational, under 100 words, end with a question to encourage comments. Instagram: a tight caption with five relevant hashtags only. The more precise your instructions, the less editing you'll need to do on the output.

Q5: Do I need to record new content to post consistently on social media?

A: Most business owners already have more usable material than they realise, old YouTube videos, webinar recordings, podcast episodes, even questions they answer on client calls every week. Once you have a structured prompting method, turning existing recordings into social posts takes minutes rather than starting from scratch.
