The advertising agency I work for just got a Sony PMW-EX1 to replace our old BetacamSP unit (Sony DXC-637 shooting to a PVV-3 Deck).
So far our downconverted HD from the EX1 doesn't look as good as the SD material shot with our old DXC-637. However, we are uable to downconvert our HD properly. Ideally, we'd use the Blackmagic Multibridge Pro to capture an SDI-HD signal from the EX1 for downconversion. I did not realize that our PC was built prior to PCI-express, so we would be unable to use the Multibridge with our system.
Bottom line question is this. Should properly downconverted HD from the PMW-EX1 look better than SD from the DXC-637? Back in its day the DXC-637 was an expensive camera.
