Generate Video from JSON: AI Context and API Workflow Zvid has released a public API workflow that enables developers to generate videos from structured JSON data. The process involves defining the video as a JSON payload, submitting it to the rendering API, and polling the job status until the final video URL is ready. The API supports defining canvas size, duration, frame rate, text layers, images, audio tracks, and output format through a single POST request to `https://api.zvid.io/api/render/api-key`. 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 https://docs.zvid.io/docs/getting-started?utm source=devto&utm medium=syndication&utm campaign=zvid blog , the Authentication guide https://docs.zvid.io/docs/authentication?utm source=devto&utm medium=syndication&utm campaign=zvid blog , the JSON Structure overview https://docs.zvid.io/docs/structure?utm source=devto&utm medium=syndication&utm campaign=zvid blog , and the published deep dive JSON to Video API: Convert JSON to Video with Zvid https://zvid.io/blog/json-to-video-api-complete-guide-for-developers?utm source=devto&utm medium=syndication&utm campaign=zvid blog . 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 https://zvid.io/blog/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: curl -X GET https://api.zvid.io/api/user/profile \ -H "x-api-key: YOUR API KEY" curl -X POST https://api.zvid.io/api/render/api-key \ -H "Content-Type: application/json" \ -H "x-api-key: YOUR API KEY" \ -d @render-job.json curl -X GET https://api.zvid.io/api/jobs/$JOB ID \ -H "x-api-key: YOUR API KEY" Generating a video from JSON means your timeline is described as data instead of being trapped inside a manual editor file. That JSON can define the canvas size, video duration, frame rate, background color, text layers, images, videos, audio tracks, subtitle timing, and output format. Zvid then validates the payload, queues the job, renders the composition, and returns the result when the job is done. This is useful when: If you only need one handcrafted launch video, a manual editor may still be faster. If your product already thinks in structured inputs, JSON rendering is usually a much better fit. The working loop is: build the JSON payload, submit the job, poll the result, then store or publish the finished video URL. In other words, the JSON file or JSON object acts like a video template plus the values that should fill it. Keep payload generation, submission, and job polling as separate steps. In practice, the flow looks like this: payload object. POST https://api.zvid.io/api/render/api-key . jobId , status , and queue details. GET https://api.zvid.io/api/jobs/{id} until the state is completed or failed . result.url when the render finishes.The Submit render job reference https://docs.zvid.io/docs/endpoints/submit-render-job?utm source=devto&utm medium=syndication&utm campaign=zvid blog is the canonical source for the request body, and the Get render job status reference https://docs.zvid.io/docs/endpoints/get-render-job?utm source=devto&utm medium=syndication&utm campaign=zvid blog is the canonical source for the polling response shape. If you are evaluating the workflow for the first time, the right CTA is simple: copy one payload, submit one render, and verify one finished result before you design anything more ambitious. The render request body must contain a top-level payload . Inside that payload, the main fields are name , resolution , duration , frameRate , outputFormat , backgroundColor , visuals , audios , and subtitle , as described in the JSON Structure overview https://docs.zvid.io/docs/structure?utm source=devto&utm medium=syndication&utm campaign=zvid blog , the Resolution Presets reference https://docs.zvid.io/docs/structure/properties/resolution-presets , and the Text Elements reference https://docs.zvid.io/docs/structure/text-elements?utm source=devto&utm medium=syndication&utm campaign=zvid blog .
