HTML5 has become the preferred, widely supported method of serving video on the web. This is a tools talk...but not an Amazon sales pitch. I was genuinely surprised at how easy, yet flexible ET is - and how well it dovetails with Amazon's other services and I think other people will be just as surprised. Over the last year, NYPL has been focused on transcoding decades/terabytes worth of archival quality video into high-quality HTML 5 accessible video. Using AWS has allowed us to focus on making the media and its technical and intellectual metadata available without having to own the responsibility of running and monitoring a fleet of transcoding machines.
