Process

How it works

A simple 3-step system flow that a non-technical user can follow.

Step 01

Step 1: Generate Creative Brief

Google Gemini analyzes the input image and creates a cinematic 8-second concept prompt describing visuals, dialogue, and mood.

Step 02

Step 2: Parallel AI Execution

The prompt is sent to Veo 3 to produce the video and to a Social Media Copy agent to craft an Instagram caption—these run concurrently.

Upload the video to Google Drive, prepare caption data, and schedule the post via Postiz for Instagram, merging results for the final publish.


Example

Example workflow

The video uses Gemini-driven creative direction and Veo 3 generation, with an Instagram caption crafted by the AI. The result is a ready-to-publish post that aligns with the brand and campaign goals.
