60-second talking-head script with b-roll plan

Write a script for a [LENGTH IN SECONDS]-second talking-head video for [PLATFORM, E.G. YOUTUBE / TIKTOK / LINKEDIN]. The speaker is [WHO IS SPEAKING AND WHY THEY ARE CREDIBLE, E.G. A PHYSICAL THERAPIST WITH TEN YEARS OF PRACTICE]. Topic: [TOPIC]. Audience: [WHO IS WATCHING AND WHAT THEY ALREADY KNOW]. Goal: by the end, the viewer should [ONE SPECIFIC OUTCOME, E.G. UNDERSTAND WHY X HAPPENS AND TRY ONE FIX].

Structure the script in four parts and label each with its running time:
1. Hook (first 3 seconds): open with the viewer's problem or a concrete claim, not an introduction of the speaker.
2. Setup (next 15-20 percent): state why the problem happens, in one or two sentences.
3. Body: 2-4 points maximum, each one sentence of claim plus one sentence of example or instruction.
4. Close: restate the single takeaway and give one call to action: [CALL TO ACTION].

Write in spoken language: short sentences, contractions, no jargon the audience would not use themselves. Cut any sentence that cannot be said in one breath. Assume a pace of [WORDS PER MINUTE, DEFAULT 150] words per minute and make the total word count fit the video length.

After the script, add a two-column list: for each script section, one b-roll shot or on-screen text suggestion that could replace the talking head for 2-4 seconds, described concretely enough to film or generate.
