⭐ What This Automation Does
Reads Pending tasks from Google Sheets
Generates a merged UGC image using:
Product photo
Person photo
Text instructions
Generates Start Frame + End Frame prompts using NanoBanana format
Builds a VEO3-compatible script using a dedicated system prompt
Sends everything to KIE VEO to generate video
Polls until video is ready
Uploads images & collects final URLs
Updates success/failure back to Sheets
🧠 High-Level Flow
1. Trigger
A schedule checks for rows where Status = Pending in the Google Sheet.
2. Read Pending Task
Pulls data from the row:
Product name, description, photo
Person name, description, photo
Target audience
Video instructions
Aspect ratio
3. Prepare Row Data
The workflow formats all fields into a single combined string for model prompts.
4. Generate Character-Consistent Images
Using OpenRouter (Gemini 2.5 Flash Image):
Creates a merged image containing the product + person
Uploads the merged image and stores URL
5. Generate First/Last Frame Prompts
Using the NanoBanana 2-frame prompt generator:
Creates Start Frame + End Frame descriptions
Ensures character identity and product accuracy
Produces negative prompts for safety
6. Create VEO3 Prompt
The agent creates a clean, influencer-style selfie script:
Safety rules enforced (non-erotic, modest clothing, natural look)
Uses combined metadata + merged image
Returns a VEO-ready prompt + orientation
7. Generate Video
Sends the prompt + images to KIE VEO:
Model:
veo3_fastMode:
FIRST_AND_LAST_FRAMES_2_VIDEO
8. Poll for Video Completion
The workflow waits and checks until:
Video is ready → continue
Error code ≥ 400 → fail the task
9. Update Google Sheet

On failure → mark Failed
