	I thought you all might be interested in a test we did at RIOT Santa
Monica.  We transferred Green Screen material from a Spirit to HDCam, D5,
and a full bit rate DDR.  We loaded the material into an Inferno and set the
key using the DDR xfer material.  We then applied the same set up to the
HDCam and D5 material.  The result was undetectable from one format to the
next.
