facility was monitoring the DB edit master in composite and adjusting
the machine to his scopes based on the bars when making the digital
copy. He was in manual to do this, so this resulted in several IRE of
difference on the copy (versus preset levels). The issue went away
when I simply instructed him to leave the machine in preset when
making the digital copy (aka "clone") and ignore what his composite
scope said.
I jump in:
As I recall, DigiBeta video adjustments are digital and therefore
affect the digital as well as the analog outputs. If adjustments are
made to the video while monitoring the analog output, the digital
'clone' will be affected as well. This is confirmed by Oliver's
instructions to the dub technician.
