shotstack / mp4-to-mov-demo

A demo project showing how to convert an MP4 video to MOV format using the Shotstack Ingest API.

Shotstack MP4 to MOV Demo

This sample application shows how you can use the Shotstack Ingest API to convert MP4 videos to MOV format. The Ingest API is a video transformation API that lets you upload, store, and convert videos and images into different formats, sizes, frame rates, speeds, and more.

Using an HTML web form, users can upload a video or put in a URL of an MP4 video online. After submitting the form, the video is converted from MP4 to MOV. The new file can be played in the browser or downloaded.

The demo is made with Node.js and works with the Express Framework or as a serverless project using AWS Lambda and API Gateway.

Requirements

• Node 16+
• Shotstack API key: https://dashboard.shotstack.io/register

Project Structure

The project is divided in to a two components:

Backend API

The backend API has an endpoint that receives the video file URL. The parameters are prepared in the JSON format the Ingest API expects and sent to the API. A status endpoint is called to check the progress of the transformation. When the mov file is ready the status is updated and the file URL of the mov file is returned.

The backend API source code is in the api directory.

Frontend Web Form & Player

The frontend uses Bootstrap and basic HTML to set up a form that allows the user to upload a video file or enter a file URL. jQuery is used for the interactive components of the application and to submit the data to the backend API and poll the status. There is also a video player that plays the final mov file video file when ready.

The front end API source code is in the web directory.

Installation

Install node module dependencies:

cd api
npm install

Configuration

Copy the .env.dist file and rename it .env:

cp .env.dist .env

Replace the environment variables below with your Shotstack API key (stage key) and a writable S3 bucket name:

SHOTSTACK_API_KEY=replace_with_your_shotstack_key
SHOTSTACK_HOST=https://api.shotstack.io/ingest/stage/
AWS_S3_UPLOADS_BUCKET=replace_with_an_s3_bucket_name

Run Locally

To start the API and serve the front end form (from the api directory):

npm run start

Then 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):

npm run deploy

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.
