To generate video from JSON, define the video as structured data, send that payload to a rendering API, save the returned job ID, and poll the job until the final video URL is ready. That is the practical JSON to video workflow behind most JSON video generators: your application creates the scene definition, and the renderer turns it into a finished file.
With Zvid, that flow is public and straightforward. You verify your API key, submit a payload to POST https://api.zvid.io/api/render/api-key, then poll GET https://api.zvid.io/api/jobs/{id} until the render completes. The best reference pages to keep open while you implement it are the Getting Started guide, the Authentication guide, the JSON Structure overview, and the published deep dive JSON to Video API: Convert JSON to Video with Zvid.
Structured JSON becomes a repeatable render workflow when the payload shape stays stable.
If you want to see the broader feed-driven pattern after this tutorial, the same ideas also show up in How to Create Product Videos from a CSV or Product Feed. The difference here is that we are starting with one payload and one render job instead of a larger automation pipeline.
Here is the minimal public API sequence most developers start with:
