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.
