Video codec used is VC-1 Advanced Profile. Audio codec used is WMA Professional at 44.1 kHz 16-bit stereo.
All March Madness games are being encoded by MLB.com’s encoding facilities using Inlet Spinnaker 7000 encoders. The Spinnakers were configured based on my own recommendations in order to provide maximum quality at all bitrates.

Well, for better of worse, you have found yourself in my little corner of the web.
RWVC.com is a sister-site for my book, Real World Video Compression, which was published by Peachpit. The goal of this site, much like the book, is to demystify video compression and help those looking to tackle problems they are having converting their video from one format to another.
