βοΈ The Perfect Tool Stack: n8n + Heygen + Synthesis.io + Submagic
Letβs break down the magic combo that powers your video automation workflow π
π 1. n8n.io β The Automation Brain
n8n.io is an open-source automation tool that connects your favorite apps, APIs, and AI tools. Think of it as the Zapier for developers, but way more flexible and powerful.
In our setup, n8n will:
- Collect your uploaded project images or text files.
- Trigger the video generation process.
- Pass data to Heygen and Synthesis.io automatically.
- Send the final video to Submagic for subtitles.
- Upload or store the video output automatically.
This means once your workflow is created, you just upload your files β and the rest happens hands-free.
π§° 2. Heygen β The Content Generator
Heygen helps generate text templates and scripts automatically.
You can set Heygen to create:
- A video script for your uploaded project.
- A short description for your post.
- A caption for your social media.
It basically transforms your idea or images into ready-to-use text content, which Synthesis.io will later convert into AI voiceovers.
π£οΈ 3. Synthesis.io β The Human-Like AI Voice Generator
Synthesis.io is an advanced AI voice generator that creates lifelike voiceovers from text.
No robotic tone. No awkward pauses.
It sounds just like a real human narrator.
In your n8n workflow:
- The text script from Heygen is passed to Synthesis.io.
- It generates a realistic voiceover.
- You can even choose different tones, accents, or genders.
This is where your video starts feeling alive β without recording a single line yourself.
π¬ 4. Submagic β Auto Subtitles and Captions
Submagic adds auto captions and subtitles to your video.
Once n8n receives the voiceover and visuals, it sends the video to Submagic. Within seconds, you get:
- Auto-generated captions
- Perfect subtitle sync
- Styled text animations
This makes your video more engaging and social media-ready instantly.
π§© How the Automation Workflow Looks in n8n
Hereβs a simple breakdown of how the full process flows:
- Upload Project Images β Stored in Google Drive or Notion.
- n8n Trigger β Detects the upload and starts the workflow.
- Heygen Node β Creates the script automatically.
- Synthesis.io Node β Converts text to realistic human voice.
- Video Generator Node β Combines images + voice into a full video.
