For the MediaConverter service, is it possible to use a source other than s3?

AWS MediaConvert currently supports only Amazon S3 as the input source for media files. However, you can work around this limitation by downloading the video from Vimeo to an S3 bucket and then using MediaConvert to convert the video to the desired format

In addition to Amazon S3 sources, you can specify a URL from a generic HTTP(S) location.

Input requirements are as follows:

• All input files must be publicly readable.
• The HTTP(S) server must not require authentication.
• The HTTP(S) server must accept both HEAD and range GET requests.
• The URL that you specify can't include parameters.

If your HTTP(S) input uses redirection, it must follow these restrictions:

• You can redirect only once from the URL that you provide as your input. You can't redirect to a URL that, in turn, contains a redirect.
• The HTTP(S) status response code from the initial server must be either 301 or 302.
• The HTTP(S) response from the initial server must use its Location headers to provide the URL that it's redirecting MediaConvert to.
