Demos¶
Below you will find many different examples and demos of OpenShot Cloud API. Sample code is provided in many common programming languages, including Python, C#, and JavaScript.
Demo App (simple-editor)¶
Check out our free demo app (simple-editor), built with JavaScript, Node.js, and Vue 3, powered by OpenShot Cloud API. This demo is designed as both a showcase for how OpenShot Cloud API can be used and a jump-start for your own software development projects based on OpenShot Cloud API! The source code is licensed under the MIT license, and can be used with both open-source and commercial applications.
Create and manage video editing projects:
Upload files, preview videos, and create clips:
Python Example Script¶
Here is a simple example client script, using Python 3. It connects, creates a new project, uploads a file, creates a clip, and then exports a new video. It should give you a good sense of how things work in general, regardless of programming language. Learn more about the API Endpoints.

Node.js Example Script¶
Here is a simple example client script, using JavaScript and Node.js. It connects, creates a new project, uploads some files, creates some clips, exports a video, and then downloads the new video file. It should give you a good sense of how things work using asynchronous JavaScript. Learn more about the API Endpoints.

C# Example Script¶
Here is a simple example client script, using C# (.NET version: 5.0.103). It connects, creates a new project, uploads a file, creates a clips, exports a video, and then prints the new video file link. It should give you a good sense of how things work in C# (This code has been made synchronous on purpose). Learn more about the API Endpoints. This also uses 2 NuGet packages: Newtonsoft, MimeMapping
