Step-by-step guide

Write the VSL script

ChatGPT2 h

Use ChatGPT to write a structured VSL script: hook (0–30s), problem agitation (30–90s), solution introduction (90–3min), social proof (3–5min), offer and CTA (5–7min).

Heat score:53Cooling Down

💡Use the PAS framework: Problem, Agitation, Solution — it's the most proven VSL structure

💡Ask ChatGPT to write 3 different hooks and test which converts best before filming the full video

✓Output: 7–10 minute VSL script with timestamps and delivery notes

Create your AI avatar presenter

Heygen2 h

Upload a reference photo and record a 2-minute voice sample in HeyGen to create a photorealistic AI avatar that presents the script.

Heat score:29Heating Up

💡Record your reference audio in a quiet room — HeyGen voice quality depends heavily on input quality

💡Use HeyGen's 'Instant Avatar' for quick tests, then upgrade to Studio Avatar for final production

✓Output: AI avatar video reading the full VSL script

Generate voiceover variants

ElevenLabs30 min

Use ElevenLabs to create high-quality voiceover alternatives with different tones — professional, urgent, conversational. Test which converts best.

Heat score:7Fading

💡Clone your own voice in ElevenLabs for a version that sounds exactly like you speaking normally

💡Generate an urgent version and a conversational version — run them as A/B tests on your landing page

✓Output: 2–3 voiceover variants for A/B testing

Edit and add B-roll in CapCut

CapCut3 h

Assemble the HeyGen avatar video in CapCut, add B-roll footage, product screenshots, testimonial clips, and animated text callouts.

Heat score:13Cooling Down

💡Use CapCut's auto-caption feature to add subtitles — 85% of videos are watched on mute

💡Add animated text callouts on every key claim to reinforce what the presenter says

✓Output: Polished VSL ready to embed on your landing page

Deploy and iterate

ChatGPT1 h/week

Embed the VSL on your landing page above the fold. Track play rate, watch time, and conversion rate. Iterate on the hook and CTA based on data.

Heat score:53Cooling Down

💡If play rate is under 60%, the thumbnail or first frame isn't compelling — test a new hook

💡If watch time drops at a specific point, that section of the script needs to be cut or rewritten

✓Output: Live VSL with tracking; conversion baseline established
