How this service works
Creatify talking-avatar video. Provide **`avatar_id`**, **`voice_id`**, and **`prompt`**. Optional **`bg_image_url`**, **`audio_url`**, **`aspect_ratio`** (`1:1`, `16:9`, `9:16`), **`show_caption`** (`On`/`Off`). List avatars/voices via internal **GET** routes (not in public schema).
Output
Returns a video asset (or a job ID in async mode) representing the rendered talking-avatar clip, where the chosen avatar's mouth and face are lip-synced to the provided speech script using the selected voice, composed over the optional background image at the specified aspect ratio, with or without burned-in captions.
Example use cases
Marketing spokesperson video
“Generate a talking-avatar video using avatar 'av_female_pro' and voice 'voice_en_us_01' with the script 'Discover our new product line this summer — quality you can trust.' Set it to 16:9 with captions on and this background: https://mybrand.com/studio-bg.jpg”
Social media portrait clip
“Make a 9:16 vertical avatar video with avatar 'av_casual_01' and voice 'voice_en_uk_03' saying 'Hey! Don't miss our weekend flash sale — 30% off everything.' Turn captions on so viewers watching without sound can follow along.”
Multilingual e-learning intro
“Create a talking-avatar video with avatar 'av_trainer_02' and voice 'voice_es_mx_01' delivering this script: 'Bienvenidos al módulo de capacitación — vamos a comenzar.' Use a 1:1 square format with captions off and this slide as the background: https://elearn.example.com/slide1.png”
Technical details
Endpoint
POSThttps://agents.vimmerse.net/v2/video/avatars/lip-sync?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a talking-avatar video where a specific pre-built avatar persona speaks a custom script with lip-sync, especially for spokesperson content, marketing clips, e-learning, or social media. Prefer this over general video generation when avatar identity and lip-sync accuracy are the priority. Use async_mode with a webhook when rendering time is a concern for long scripts.
Side effects
- Invalid or unrecognized avatar_id — avatar not found or not accessible
- Invalid or unrecognized voice_id — voice not available
- Empty or missing prompt with no audio_url fallback — no speech content to sync
- Invalid aspect_ratio value — must be '1:1', '16:9', or '9:16'
- Unreachable bg_image_url or audio_url — network fetch failure
- Insufficient credits — payment or credit balance too low
- Async job failure — job ID returned but rendering fails downstream; must poll for status
- Webhook delivery failure — webhook_url unreachable or returns non-200
