Hi,
again I was selected speaker for MS community on field of digital media.
http://kulendayz.mscommunity.net/
This was level 400 session, short introduction to Expression Encoder and then in depth voyage of VC-1 codec with optimizations techniques.
But :(, actually there aren't many listeners capable of of this level, not that they wouldn't understand, but they just don't need that level of in depth session.
So yes, once again, I had to go higher, higher :).
Microsoft should give me t-shirt of their Evangelist team :), because I spend so much time preaching about benefits of Windows Media, trough last six or seven years I was selected speaker for MS Media technologies :)
Just in case, my size is XL :)
