Episodic TikTok Shorts n8n: Seedance 2.5 + GPT-6 + Replicate

Episodic TikTok Shorts automation: Seedance 2.5 episodes generated daily from your Google Sheets

Meet Episodic TikTok Shorts n8n: Seedance 2.5 + GPT-6 + Replicate—a scheduled n8n workflow that automatically turns your episode & character data in Google Sheets into a 30-second Seedance 2.5 video, then saves a TikTok draft via SocialRobot (with optional Instagram Reels and Threads posting).

What this workflow does

• Runs daily at 18:00 using a schedule trigger.
• Reads your Google Sheets “Episodes” tab, selecting the first episode that isn’t marked done/failed, and pulls the most recent completed episode summary for continuity.
• Loads character references from the “Characters” tab (URLs + descriptions) and prepares ordered reference inputs.
• Uses OpenAI (GPT-6 Luna) to generate a timed multi-shot Seedance 2.5 prompt, an episode title, platform-specific captions, and a short episode summary.
• Renders the video on Replicate by submitting a Seedance 2.5 reference-to-video job, polling until success/failure/timeout, then downloading the resulting MP4.
• Validates the output (file size, type, duration) before posting.
• Uses SocialRobot to save a TikTok inbox draft and optionally publish to Instagram Reels and Threads.
• Updates Google Sheets with status, post IDs, produced timestamp, and the new summary—or records a readable error message if the episode fails.

Use cases

• Content teams managing episodic TikTok Shorts from a spreadsheet workflow.
• SaaS operators building an automated video pipeline without manual prompt and upload steps.
• Automation engineers testing a full loop: Google Sheets → GPT prompt → Replicate render → SocialRobot posting.
