Shotstack Pexels Slideshow Video Demo
An HTML web form allows the user to search the Pexels library via the Pexels API, choose a soundtrack and add a title. Luma matte transitions are also used to create a more engaging video effect. The final video is the created by the Shotstack API using the images returned by the Pexels search and the soundtrack and title entered by the user.

The demo is built using Node JS and can be used with either Express Framework or deployed as a serverless projects using AWS Lambda and API Gateway.
- Node 8.10+
- Pexels API key: https://www.pexels.com/api
- Shotstack API key: https://dashboard.shotstack.io/register
The project is divided in to a two components:
The backend API with an endpoint which searches the Pexels API, prepares the edit and posts the data to the Shotstack API. A status endpoint is also available which can be polled to return the status of the video as it renders.
The backend API source code is in the api directory.
Frontend Web Form & Player
The frontend is a simple HTML form that allows the user to enter a search term and basic options to create a video. The form uses jQuery to submit the data to the backend API and poll the status of the current render. There is also a video player that is loaded with the final rendered video when ready.
The front end API source code is in the web directory.
Install node module dependencies:
cd api npm install
Copy the .env.dist file and rename it .env:
cp .env.dist .env
Replace the environment variables below with your Pexels and Shotstack API key (staging key):
To start the API and serve the front end form (from the api directory):
npm run start
The visit http://localhost:3000
Deploy Serverless Application (optional)
The project has been built as a serverless application using the Serverless Framework and AWS Lambda. To understand more about the Serverless Framework and how to set everything up consult the documentation: https://serverless.com/framework/docs/providers/aws/
To deploy to AWS Lambda (from the api directory):
cd api npm run serverless
Once the API is deployed set the
var apiEndpoint variable in web/app.js to the returned
API Gateway URL.
Run the web/index.html file locally or use AWS S3 static hosting to serve the web page.
