Workflow steps

1

Write the video script with Jasper

Jasper

Use Jasper to write a 30-60 second video ad script. Focus on a strong hook in the first 3 seconds, a clear problem-solution structure, and a direct CTA at the end.

Prompt template
Write a 45-second video ad script for [PRODUCT] targeting [AUDIENCE]. Structure: (1) Hook — attention-grabbing opening statement or question (3 seconds), (2) Problem — pain point the audience faces (10 seconds), (3) Solution — how the product solves it (20 seconds), (4) Social proof — one specific result or testimonial (7 seconds), (5) CTA — clear next step (5 seconds). Conversational tone, no jargon.

Generate the primary video with Synthesia

Synthesia

Paste your script into Synthesia. Choose an avatar that matches your target audience demographic. Select the language and accent, then generate the video.

3

Create a UGC-style variant with HeyGen

HeyGen

Use HeyGen's Instant Avatar feature to create a more casual, UGC-style version of the same script. This gives you a polished spokesperson version (Synthesia) and a raw UGC variant (HeyGen) to A/B test.

4

Add captions and export for each platform

Download both videos and add auto-captions. Export in 16:9 for YouTube and Connected TV, 1:1 for Facebook feed, and 9:16 for TikTok and Reels. Launch both variants as a creative test.
