Seattle-based Amazon Web Services is muscling its way into the video transcoding market today, saying that it has launched a new service called Amazon Elastic Transcoder, which will help customers transcode video files between different media formats. According to Amazon, the new service will remove the need for customers to manage their own infrastructure and transcoding software. Transcoding is the process needed when videos are uploaded to the Internet, to convert them into different formats streamed to different kinds of devices. Amazon said it will charge customers based on the number of minutes they need to transcode, and the resolution. Amazon said it was looking to reduce the expense of purchasing transcoding software, the difficulty of setting up and running that software, and to help accommodate peak workload and demand for transcoding.
