[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/git/external?repository-url=https://github.com/vercel/next.js/tree/canary/examples/with-mux-video&project-name=with-mux-video&repository-name=with-mux-video)
Execute [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app) with [npm](https://docs.npmjs.com/cli/init), [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/), or [pnpm](https://pnpm.io) to bootstrap the example:
**Important:** When creating uploads, this demo sets `cors_origin: "*"` in the [`pages/api/upload.js`](pages/api/upload.js) file. For extra security, you should update this value to be something like `cors_origin: 'https://your-app.com'`, to restrict uploads to only be allowed from your application.
- Dynamic routes using [`getStaticPaths` and `fallback: true`](https://nextjs.org/docs/basic-features/data-fetching/get-static-paths), as well as dynamic API routes.
All you need to set this up is a [Mux account](https://mux.com). You can sign up for free and pricing is pay-as-you-go. There are no upfront charges, you get billed monthly only for what you use.
Without entering a credit card on your Mux account all videos are in “test mode” which means they are watermarked and clipped to 10 seconds. If you enter a credit card all limitations are lifted and you get \$20 of free credit. The free credit should be plenty for you to test out and play around with everything before you are charged.
### Step 2. Set up environment variables
Copy the `.env.local.example` file in this directory to `.env.local` (which will be ignored by Git):
```bash
cp .env.local.example .env.local
```
Then, go to the [settings page](https://dashboard.mux.com/settings/access-tokens) in your Mux dashboard set each variable on `.env.local`, get a new **API Access Token** and set each variable in `.env.local`:
-`MUX_TOKEN_ID` should be the `TOKEN ID` of your new token
You can deploy this app to the cloud with [Vercel](https://vercel.com/new?utm_source=github&utm_medium=readme&utm_campaign=next-example) ([Documentation](https://nextjs.org/docs/deployment)).
To deploy on Vercel, you need to set the environment variables using [Vercel CLI](https://vercel.com/download) ([Documentation](https://vercel.com/docs/cli#commands/secrets)).
Install the [Vercel CLI](https://vercel.com/download), log in to your account from the CLI, and run the following commands to add the environment variables. Replace the values with the corresponding strings in `.env.local`:
Then push the project to GitHub/GitLab/Bitbucket and [import to Vercel](https://vercel.com/new?utm_source=github&utm_medium=readme&utm_campaign=next-example) to deploy.
