AWS offers 20 minutes of free video conversion each month. After that, users will be charged based on resolution, the length of video copied and the user's location. For customers in the Eastern U.S., for instance, encoding standard definition video will cost US$0.015 per minute of footage and high-definition encoding (720p and above) will cost $0.030 per minute.
AWS is not alone in offering transcoding as a Web service. Last week, Microsoft introduced an Azure-based video delivery service that included transcoding functions as well.
