Re: Lessons to be learned from Einstein reports

Guys,
One of the biggest failings when speaking about cameras is discussing baseband video when it is in fact, MPEG. Teams should read a few papers in the off season on how MPEG actually encodes video and how it transmits data. Merely reducing frame rate and resolution do not reduce bandwidths when fast moving objects and moving backgrounds are in the field of vision. The codecs used to compress MPEG video for HD TV are complex and highly adaptive/predictive. You don't notice many of the artifacts, but professional video people do. Just reducing video noise is one of the steps employed prior to encoding as the noise is considered live video by the codecs. Aggressive noise reduction can actually make rain disappear in video.
