This guide outlines how to turn a simple Trello board into an autonomous video production factory. The goal is to treat the AI Agent not as a tool, but as a staff member (a “Junior Editor”) that handles assembly, syncing, and variations, leaving the creative strategy to you.

The Tech Stack

• Project Management: Trello (used as the command center).
• The Brain: Poolday via API (The specific AI agent I showed you in the video. Let me know if you need an intro or actually, if you email alex@poolday.ai the founder he’ll make you skip the waitlist and get you setup. But don’t tell anyone!) 
• The Assets: Your raw video files, voiceovers, and brand guidelines.

Step 1: Configure Your Board Architecture

The automation relies on moving cards through specific columns to trigger different AI behaviors. Set up your Trello board with these exact lists (as seen in the video):

1. To Do: Where you drop raw ideas and assets.
2. In Progress: The “kitchen.” The AI moves cards here while it works.
3. To Be Reviewed: The holding pen for completed drafts waiting for human eyes.
4. Done: The trigger for the next phase.
5. Variations: Where the AI dumps alternative versions (hooks, pacing, music) automatically.
6. To Be Published: Final, approved assets ready for upload.

Step 2: The Brief (Triggering the Agent)

You don’t need to prompt the AI with complex code. You just need to create a Trello card.

1. Create a Card: Name it clearly (e.g., “Product Promo – Coffee Grinder” or “App Lens Scan”).
2. Upload Assets: Attach your raw video files, logos, and screenshots directly to the card.
3. Write the Description: In the card description, write a simple brief.
   • Example: “Create a vertical video for User Acquisition. Highlight the stable scanning motion. Keep pacing fast. Optimized for TikTok.”
4. The Handoff: As soon as the card is created/configured, the Poolday Editor Agent detects it. This happens through no-code automations like Zapier/Gumloop etc, the Poolday team generously offered to set that up for people coming from my community.

Step 3: The Analysis & “Thinking” Phase

Once the agent picks up the card, it moves it to In Progress. It performs two distinct actions (visible in the video logs):

• Creative Strategist Agent: Reads your brief and analyzes the raw footage. It identifies objects (e.g., “Old Coin,” “Plant,” “Building”) using computer vision.
• Video Editor Agent: structured the timeline. It decides where to cut, which music track fits the vibe, and how to sync the transitions.

Note: You do not do anything during this step. The agent is working in the background.

Step 4: Reviewing the First Draft

When the draft is ready, the Agent moves the card to To Be Reviewed and leaves a comment with a link.

1. Click the Link: This opens the Poolday editor interface.
2. Inspect the Timeline: Unlike a static MP4 file, you get a fully editable timeline. You can see:
   • Music Tracks: Synced to the visuals.
   • Visual Layers: The AI automatically centers significant objects (like the coin or plant in the demo).
   • Overlays: It adds UI elements (like the scan frame) automatically based on the context.
3. Approve or Tweak: If it looks good, you’re ready for the next step. If not, you can manually adjust cuts right there.

Step 5: The “Infinite” Variation Loop

This is the most powerful part of the workflow. The moment you are satisfied with the main concept, you drag the card to Done.

The Automation Trigger: Moving a card to “Done” tells the Agent: “The core concept is good. Now, give me options.”

The Agent immediately starts generating Variations and populating that column. It creates:

• Pacing Variations: It will create a “Fast” cut (e.g., 21 seconds) and a “Slow” cut (e.g., 28 seconds) to test attention spans.
• Hook Variations: It swaps the first 3 seconds (e.g., switching from a visual hook to a UGC-style face hook).
• Audio Variations: It swaps the background music and sound effects to change the emotional tone.

Step 6: Final Export

1. Review the cards in the Variations column.
2. Select the winning creatives.
3. Move them to To Be Published.
4. Download the final MP4s for upload to Meta/TikTok Ads Manager.

Summary of Results

• Time Saved: Process reduced from ~5 hours to ~10 minutes per video.
• Role Replaced: The AI effectively handles the workload of a Junior Video Editor.
• Output: You get 1 master video + 3-5 variations automatically, solving the issue of “Creative Fatigue” in paid media.
• Contact: if you email alex@poolday.ai the founder he’ll make you skip the waitlist and get you setup
