Prompt
Act as a content editor who specializes in repurposing long videos (YouTube, video podcasts, webinars) into vertical short-form clips.
Context:
- Timestamped transcript: {{transcript}}
- Channel topic and audience: {{channel}}
- Number of clips I want: {{number}}
- Maximum length per clip: {{length}}
- Goal of the clips: {{goal}}
Deliverables:
1. A table with the {{number}} best segments: exact start and end times from the transcript, the clip's idea in one sentence and why it works on its own, without the full video's context.
2. For each clip:
- The first line exactly as it appears in the transcript and, if it is weak, an on-screen text hook to reinforce it (without changing what the speaker says).
- Suggested internal cuts (which lines to remove) so it stays under {{length}}.
- A title or cover text (max 50 characters) and a short description with 3 relevant hashtags.
- 9:16 vertical reframing and caption cues (words to highlight).
3. A recommended posting order and which clips should link back to the full video.
4. Segments that should NOT be clipped because out of context they could be misread.
Constraints:
- Only use lines that exist in the transcript. Do not invent quotes or change the meaning of what was said.
- If the transcript has no timestamps, say so and estimate the position with [FILL IN: minute].
- Each clip needs a beginning, middle and end that make sense on their own.
- If information is missing, ask me first.
Format: a summary table and one card per clip.How to use it
- Export a timestamped transcript from YouTube Studio, your editor or a transcription tool and paste it in full.
- Check the suggested timings in your editor: they may need a second or two of adjustment.
- Stagger the clips over time and link the full video from the best performers.
Usage example
Transcript: 45-min interview with a dietitian · Channel: healthy family cooking · Clips: 6 · Length: 45 s · Goal: drive traffic to the long video.
Sample output
The transcript hasn't been pasted yet, so here is the structure ready to go with the gaps marked. Once you add it, I'll fill in the timestamps and the verbatim lines.
Summary of the 5 clips
| # | Start-end | Clip idea | Why it stands alone |
|---|---|---|---|
| 1 | [FILL IN: minute] | [FILL IN: specific storefront tip] | Problem and fix in under 60 s |
| 2 | [FILL IN: minute] | [FILL IN: common social media mistake] | Clear without prior context |
| 3 | [FILL IN: minute] | [FILL IN: customer story] | Has a setup, a turn and a payoff |
Clip 1 card
- First line (verbatim): [FILL IN: exact quote from the transcript]
- On-screen hook (if the line is weak): "The mistake in your shop window" (does not change what the speaker says)
- Internal cuts: remove the opening tangent and the repeated ending to stay under 60 s.
- Cover text: "3 fixes for your shop window" (28 characters)
- Description: Full breakdown in the long video. #smallbusiness #localmarketing #shoplocal
- 9:16 reframe: keep the face centered; captions highlighting the key words.
Do not clip
- Any segment that criticizes another business: out of context it could be misread…

Frequently asked questions
What makes a segment work as a short?
It makes sense without context, starts with a strong line and contains one complete idea: an opinion, a tip, a short story or an emotional moment.
Can I rewrite what the guest says?
