A CNAME record is "a type of resource record in the Domain Name System (DNS) used to specify that a domain name is an alias for another domain" according to Wikipedia. You can create a CNAME record and point it to your SproutVideo website, allowing you to use an existing domain name you own for your video site, or to use a ".com" address instead of the "vids.io" address we provide.
If you use GoDaddy as your domain hosting provider, follow these instructions for creating a CNAME record and pointing it to your SproutVideo website.
Set the "Record Type" to CNAME (Alias). Set "Host" to be whatever you would like the prefix of your URL to be. Common examples are “www” or “videos”, which you would enter without the quotation marks. Enter your custom Video Site URL from your SproutVideo account in the "Points to" field. You can find this under Site > Settings when logged into your SproutVideo account. The final URL in the example below would be videos.example.com.
Once your GoDaddy account is configured, log into your SproutVideo account. Hover your cursor over "Site" at the top of the page, and select "Settings". Enter the CNAME record in the corresponding field called "CNAME" and click "Save Settings" at the bottom of the page. We will automatically test your new URL to make sure that it is configured correctly.
