Turn one long video into a week of short clips

You've got a talk, a webinar, a live Q&A or a long how-to video. Get it cut into short vertical clips with hooks and captions you can post all week.

The prompt · ChatGPT

Help me turn one long video into short clips.

What the video is: [e.g. a 40-minute talk on choosing a boiler]
Transcript or notes: [paste the transcript with timestamps if you have it, or a summary]
Who I want to reach: [your customer]
Where the clips will go: [e.g. Instagram Reels, TikTok, YouTube Shorts]
Tool I'll use to cut it: [e.g. CapCut]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. The 5 to 10 strongest moments, each with start and end timestamps, 20 to 60 seconds long, that make sense on their own.
2. For each clip: a hook line for the first 2 seconds, a caption and one call to action.
3. A posting order for the week, best clip first.
4. Short, general steps for cutting and captioning the clips in my tool.
5. What to check before posting: captions spelt right, nothing taken out of context.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts or results. UK English.

Stay in this ChatGPT chat. Do not turn on apps or connectors, and do not use memory from another chat.

A short example

Fill the blanks, then paste. e.g. a 40-minute talk on choosing a boiler: a short note you already have. paste the transcript with timestamps if you have it, or a summary: a short note you already have. Leave the rest of the prompt as written.
