How Synthesia Prompts Work
Synthesia turns scripts into AI-avatar videos, so your "prompts" are mainly:
- Script prompts (what the avatar says, scene by scene)
- Instruction prompts (how ChatGPT/AI should write those scripts)
- Avatar/look choices
Synthesia's own guides recommend: be specific about topic, audience, goal, and length; write in short, conversational sentences; and keep scenes concise, aiming for around 130–150 words per minute and multiple scenes instead of one long block.
Meta-Prompts to Generate Synthesia Scripts (Use with ChatGPT)
Synthesia explicitly encourages using AI (like ChatGPT) to generate scene-by-scene scripts using robust prompts. You can publish these as copy-paste "super-prompts" for your readers.
General script generator (base template)
"You are writing a script for a Synthesia AI avatar video. Topic: [topic]. Audience: [who they are]. Goal: [what they should know/do after watching]. Length: [X] minutes. Structure: Hook (10–15 seconds), 3 main points with simple examples, then a clear call-to-action. Tone: [friendly/professional/enthusiastic]. Write short, spoken-style sentences and avoid long paragraphs."
Meta-prompts by use-case

Prompting for Scene Structure & Visuals
Synthesia's templates and "Generate with AI" features break videos into scenes with avatars, background media, and on-screen text.
- "For each scene, output: Scene title, on-screen text (max 10 words), and avatar narration (40–60 words). Make the on-screen text support, not duplicate, the narration."
- "Write a 5-scene script. Each scene should include: 1) short heading, 2) one visual suggestion (icon, B-roll, or simple animation), 3) 2–3 short sentences for the avatar to say."
- "Use the FOCA framework (Focus, Outcome, Content, Action) for a 60-second video: one sentence for focus, two for outcome, three for content, and one for action."
Best Practices for Strong Synthesia Prompts
- Always define goal, audience, and length in the prompt before asking for a script; this dramatically improves relevance.
- Write for the ear, not the eye: short sentences, everyday language, and about 130–150 words per narrated minute.
- Use scene-by-scene structure instead of dumping everything in one scene; this gives better pacing and easier edits.
- Iterate with feedback: generate a first draft, then prompt the AI to "make it shorter", "more conversational", or "add an example" rather than starting over.
- Test voices and avatars: Synthesia suggests trying 2–3 voices on your first scene and picking the best match before generating the full video.
