To speed up your S3 media delivery to your members/viewers even faster than what S3 already gives you, by adding CloudFront on top of your S3 buckets, enter the CloudFront Public and Private Keys from your AWS account in the respective fields above.

IMPORTANT: Click on "Create CloudFront Distribution" button only after filling out the above keys first.

Your CloudFront Public & Private Keys can be found within your AWS account.

See the CloudFront Integration video at S3MediaVault.com/doc/ that shows you how to retrieve this information.

NOTE: Using CloudFront together with S3 will make your downloads and media loading way faster than just S3. But there are added costs, even if extremely inexpensive (like fractions of a penny, etc). See this for pricing.
