📅 100 Daily Prompts Automation
You can scale this workflow to generate one video per day from a batch of 100 prompts in Google Sheets.
Setup Steps
Add 100 prompts to your Google Sheet — one per row.
Set the Status column for each to Pending.
Use a Cron Trigger in n8n to run the workflow once daily (e.g., at 9 AM).
Each run picks one Pending prompt, generates a video, uploads to YouTube, then marks it as Done.
Continues daily until all 100 prompts are processed.
Example Cron Expression
0 9 * * *
→ Runs the automation every day at 9:00 AM.
Node Sequence
[Schedule Trigger (Daily)] → [Get Pending Prompt from Sheets]
→ [Gemini Prompt Parser] → [MagicHour Video Generation]
→ [Optional: MediaFX Audio Mix] → [Gemini Metadata Generator]
→ [YouTube Upload] → [Update Row in Sheets]
💡 Optional Enhancements:
Add a notification node (Slack, Discord, or Email) after each upload.
Add a counter check to stop after 100 videos.
Add a “Paused” column to skip specific rows.
