What is a video editing API?
A video editing API lets you create, edit and render videos programmatically — without opening a video editor. Instead of dragging and dropping clips in a timeline, you describe your video in code (or JSON) and the API renders the final MP4 in the cloud.
This is essential for businesses that need to produce videos at scale: personalized marketing videos, social media content, product showcases, news summaries, real estate tours, and more.
Why use a video editing API?
- Scale: Generate hundreds or thousands of videos from data — product catalogs, property listings, news feeds
- Consistency: Use templates to ensure brand consistency across all videos
- Automation: Trigger video creation from webhooks, CRM events, spreadsheets or RSS feeds
- Speed: Produce in minutes what would take hours in a manual editor
- Integration: Connect to your existing stack via REST API, SDKs (Python, JavaScript, PHP) or no-code platforms
How JSON2Video's video editing API works
JSON2Video is a cloud-based video editing API. You send a JSON object describing your video — scenes, elements, transitions, voiceover, subtitles — and the API renders it into an MP4.
1. Describe your video in JSON
A video is a JSON object with scenes. Each scene contains elements: text, images, video clips, audio, voice, and subtitles.
{
"scenes": [
{
"elements": [
{
"type": "video",
"src": "https://example.com/product-clip.mp4"
},
{
"type": "text",
"text": "New Product Launch",
"style": "subtitle"
},
{
"type": "voice",
"text": "Introducing our latest product, now available worldwide.",
"model": "elevenlabs",
"voice": "Rachel"
}
]
}
]
}2. Send it to the API
A single POST request starts rendering. You get a movie ID back to check the status.
curl -X POST https://api.json2video.com/v2/movies \
-H "x-api-key: YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d @video.json3. Get your MP4
The API renders your video in the cloud and returns a URL to the final MP4. Typical render times: 30-90 seconds for a 1-minute video.
