I have some background in working with delivering media via the web at my previous job, for example when I created BigVideo.js.
“For any given TV show, the footage shot will have been converted into over 1000 different formats”
No question, video is a pain in the ass. I was anxious to find out how AWS can make it less so. Clearly you can use it to make a great custom architecture solution for ingesting, processing and serving, with products like Amazon Elastic Transcoder, S3 multipart APIs, SQS and Elemental Cloud. But… still a pain in the ass. I expect eventually they will launch their own service similar to Brightcove. Unfortunately, not just yet.
