Create Talking Avatar Videos Workflow (n8n + Google Vids)

Create talking avatar videos with n8n + useapi.net Google Vids

Turn an n8n form submission into a ready-to-preview, downloadable talking avatar video using the useapi.net Google Vids API (Gemini Omni 1.1 Flash)—including optional extra segments and secure media streaming.

What this workflow does

• Collects production inputs via an n8n form (presenter description or saved presenter selection, voice, script, scene, aspect ratio, length, and optional additional segments).
• Manages avatar sourcing: lists saved Google Vids avatars from useapi.net for selection, or submits a request to draw a new avatar when needed.
• Provides a review step so you can confirm the portrait and voice, with an option to re-draw the avatar by deleting the previous one and generating a new portrait.
• Creates the talking video by submitting a generation job to useapi.net Google Vids to produce a 720p clip, then polling job status until the result is ready.
• Supports multi-segment videos by generating and extending the video segment-by-segment, showing a checkpoint page after each segment so you can continue or stop early.
• Optionally upscales to 1080p only when the total duration is 20 seconds or less.
• Delivers results with a results page that includes an embedded player and an MP4 download link.
• Streams media securely through an n8n webhook that fetches media from useapi.net by mediaId, so the API token is not exposed to the browser.

Use cases

• Generate branded training or product update videos from a script template.
• Build a self-serve “video in a form” workflow for SaaS customers using n8n automation.
• Produce multi-part announcements by adding optional extra segments with checkpoints.
