YouTube Water/Shark Shorts via n8n

The YT Water/Shark Shorts workflow is a fully automated YouTube Shorts content generator that creates, renders, and publishes viral-style videos without any manual scripting, editing, or uploading.
It runs entirely on schedule and transforms AI ideas into real YouTube content automatically.

Here’s how it works:

1. The system triggers automatically on a schedule

A Schedule Trigger kicks off the workflow at whatever frequency you choose (e.g., hourly, daily, weekly).

No user interaction required. Fully autonomous.

2. An AI agent generates a complete YouTube Shorts idea pack

The Scripting AI Agent (powered by custom system instructions) generates:

A YouTube Shorts title

A fun, engaging description

A detailed AI video-generation prompt

All output is formatted in JSON and must follow strict storytelling rules for virality.

The agent randomly rotates between three cinematic video types:

1. Selfie Stick Ocean POV (Shark Encounters)

Above-water, personal, dramatic.

2. Giant Wave Catastrophe

Massive wave approaching surfers or tourists.

3. Aquarium Chaos Scene

Orca viewing area with unexpected events.

This ensures content variety and avoids repetition.

3. An LLM validates the structure and fixes formatting

A Structured Output Parser ensures the JSON is valid and production-safe before moving on.

This prevents malformed prompts or broken uploads.

4. A video-generation model creates the actual video

Using the prompt, the workflow calls KIE AI’s Veo model, producing a vertical 9:16 Shorts-formatted video.

The system handles:

Rendering

Authentication

API calls

Video retrieval

Wait cycles while rendering completes

All automatically.

5. Once rendered, the system retrieves the final video

The workflow polls the video record endpoint until the video file is ready.

6. The video is uploaded directly to YouTube

Through the Blotato API integration, the system:

Uploads the AI-generated video

Applies the generated title

Applies the description

Flags the video appropriately (not for kids)

Posts it to the correct YouTube account

This eliminates all manual uploading.
