I looked into this a while back for a project I was considering. These sites came in handy: Flash Video Bitrate Calculator: http://www.adobe.com/devnet/flash/apps/flv_bitrate_calculator/ http://www.adobe.com/devnet/flash/apps/flv_bitrate_calculato... Video storage and streaming: http://aws.amazon.com/cloudfront/ http://aws.amazon.com/cloudfront/ and http://aws.amazon.com/s3/ http://aws.amazon.com/s3/ Video encoding: http://www.encoding.com/pricing/ http://www.encoding.com/pricing/ Basically you just have to figure out how much storage will cost for all the videos (take the bitrates times the length times the number of videos), and bandwidth (number of videos viewed per visitor times the total bandwidth viewed per video). You'll probably see that it is very expensive if you are not charging for access.
