Re: quality question

Mr. Kuper,

DIGI-BETA is already Digitized, hence the 'DIGI' in the name.

You could use a Pinnacle CineWave, Digital Voodoo, or other capture card
that can capture SDI uncompressed, and add no additional artifacts to
the video. Then transcode the resulting QuickTime, uncompressed file
into DVD compliant MPEG. (Because DIGI-BETA is also MPEG 2)

Thus, a Hardware encoder does not necessarily have an advantage over
software in this regard.

JD


PS - The guys at 'The Orphanage' thought the quality of Apple's encoder
was good enough to use it on a DVD for their films, which they gave away
at Sundance.
