Reliability is the primary concern as core AI video and language model tools are both in declining phases, cooling off momentum in the VSL generation pipeline. Architecture and context remain stable, but the toolchain needs refresh to restore confidence in consistent video output quality. · checked 6d ago

Setup Guide

~$2.00/run

1
Write the VSL script
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).
2
Create your AI avatar presenter
Upload a reference photo and record a 2-minute voice sample in HeyGen to create a photorealistic AI avatar that presents the script.
3
Generate voiceover variants
Use ElevenLabs to create high-quality voiceover alternatives with different tones — professional, urgent, conversational. Test which converts best.
4
Edit and add B-roll in CapCut
Assemble the HeyGen avatar video in CapCut, add B-roll footage, product screenshots, testimonial clips, and animated text callouts.
5
Deploy and iterate
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.
