How To Generate AI Videos In N8N Workflows Step By Step
If you’re ready to automate AI video generation directly inside your n8n workflows, this step-by-step guide is for you. We’ll use Scrptly — an AI Video Agent that turns your prompts (and optional reference images) into ads, product showcases, explainers, anime, or even short films. Because Scrptly’s multi-agent system handles research, character design, narration, editing, and consistency for you, it’s perfect for hands-off automation and long-form content.
Save and select these credentials in your Scrptly node
Security tip: Store your API key in environment variables for self-hosted setups and rotate keys periodically.
Step 3 — Build your first workflow
Trigger: Choose how the workflow starts.
Scrptly node: Configure the AI video request.
Example prompt you can paste
Create a 45–60 second vertical UGC-style product ad introducing our new leather messenger bag. Keep a warm, cinematic vibe with soft window light. Structure:
1) Hook (first 3 seconds): quick tease about durability and style
2) Problem (scratched bags, awkward pockets)
3) Solution (close-ups of stitching, pockets, adjustable strap)
4) Social proof (voiceover mentions 1,000+ happy customers)
5) CTA: “Shop the new leather messenger bag today.”
Maintain consistent product visuals based on the provided context images. Include gentle foley + soft lo-fi background music. End with a clean product shot and a text overlay.
Post-processing node(s): Decide where the generated video goes.
How to pass context images for consistency
In the Scrptly node → Context Images, provide URLs to key references:
Scrptly’s agent uses these to maintain consistent visuals throughout the video — crucial for ads and multi-scene explainers.
Step 4 — Synchronous vs. asynchronous runs
Wait For Completion = On: The Scrptly node holds until the video is ready, then passes the final file URL to downstream nodes. Ideal for simple flows.
Wait For Completion = Off: The node returns immediately with a task ID so you can:
Note: For most first-time setups, keep Wait For Completion enabled.
Step 5 — Distribute the result
Map the video URL payload from the Scrptly node to your distribution nodes. Common patterns:
Advanced prompt tips for higher-quality results
Be explicit about length and orientation: “60–75 seconds, vertical 9:16” or “landscape 16:9.”
Specify pacing and structure: “hook → problem → solution → proof → CTA.”
Name characters and places to keep continuity: “Ava (host), brick studio loft.”
Match your brand mood: “soft cinematic color grade, warm highlights, modern minimalist typography.”
For documentaries or explainers, ask for narration style: “clear, friendly, authoritative voice; subtle underscore.”
Common n8n setup issues (and quick fixes)
Community node installation blocked: Enable “Allow Community Nodes” in n8n settings (admin-level permission may be required).
Invalid API key: Re-check the value in Credentials; rotate the key from your Scrptly account if needed.
Empty or broken context image URLs: Verify they’re publicly accessible or pass binary files in n8n.
Exceeded token budget: Increase “Approve Up To” for complex prompts or shorten the requested length.
Missing output mapping: Expand the Scrptly node output to locate the video URL and map it to your next node.
Optional: Test Scrptly with code (outside n8n)
If you prefer to validate your prompt programmatically before wiring n8n, you can install the SDK:
Why Scrptly excels for long-form
Scrptly’s multi-agent pipeline (research, screenplay, narration, editing, and more) plus context-image consistency gives you feature-length reliability without manual stitching. That’s especially useful for tutorials, product walkthroughs, docu-style content, and narrative shorts.
Install the n8n node: Search for “n8n-nodes-scrptly” in Community Nodes
Build your first workflow in under an hour and automate your next ad, explainer, or short film
Final checklist
Prompt crafted with clear structure, style, length, and orientation
