Convert Reddit Threads into Short Vertical Videos with AI
# Convert Reddit threads into short vertical videos with AI
## Who is this for?
This workflow is ideal for:
- **Content creators** and **video editors** automating short-form content production
- **Reddit storytellers** converting text posts into engaging TikTok, YouTube Shorts, or Reels
- **Social media managers** repurposing community discussions into visual narratives
## What problem is this solving?
Manually converting Reddit posts into vertical video content is time-consuming:
- You have to read, summarize, write a script
- Generate S
- Find stock footage
- Edit everything in a timeline
This workflow automates the full pipeline. It converts any Reddit thread into a polished video with:
- S narration
- Subtitle overlays
- B-roll from Pexels
- Automatic rendering via Shotstack
## What this workflow does
This workflow:
1. **Extracts Reddit post and comments** via Reddit API
2. **Summarizes the thread into structured clips** using OpenAI
3. **Generates search queries** for each clip for stock footage
4. **Queries Pexels API** for relevant vertical videos
5. **Generates S audio** for each clip using OpenAI Whisper
6. **Creates subtitles** matching the audio
7. **Uploads footage/audio to Shotstack**
8. **Renders a full vertical video (720x1280)** with synced S, subtitles, and b-roll
9. **Returns a final video URL**
## Setup
- Create accounts and API keys for:
- [Reddit Developer App](https://www.reddit.com/prefs/apps)
- [OpenAI](https://platform.openai.com/)
- [Pexels](https://www.pexels.com/api/)
- [Shotstack](https://shotstack.io/)
- Add credentials in n8n:
- Reddit (HTTP Basic Auth)
- OpenAI (API Key)
- Shotstack (HTTP Header Auth)
- Pexels (HTTP Header Auth)
- Trigger via webhook or manual node. The input must include:
```json
{
"voice": "nova",
"ttsSpeed": 1,
"videoLength": 60,
"redditLink": "https://www.reddit.com/r/example/comments/example_id/example_title"
}
```
## How to customize this workflow
- **Tweak OpenAI prompts** to change tone or clip granularity
- **Change stock source** by swapping Pexels for another API
- **Adjust S voices** or languages by modifying the `voice` field
- **Modify video styling** (fonts, colors, fit modes) in the timeline construction code node
- **Control duration** by editing the character length formula in the `Limit comments length` node
## Additional Notes
- All stock videos are selected to match clip themes using generalized keywords to avoid API misses
- Includes `wait` nodes to ensure Shotstack's async upload/render processes complete before proceeding
- Annotated with **sticky notes** explaining major sections like S, Reddit input, and media timeline
- Avoids community nodes to ensure cloud compatibility
