[John Cummings]"Can all Betacam playback decks handle a widescreen picture? Any issues with output for digitizing or dubbing?"
When you use Beta SP decks to do 16x9, you have to cheat.
You need to make the 16x9 image anamorphic to get in on SP tape, and you have to make darned sure that the deck on the other end can play it back in the proper aspect ratio. There is no such thing as a 4x3/16x9 toggle switch on any Beta SP deck, so you need to unsqueeze the playback with hardware or software.
Like John above said, if you can record it on betasp, it can be played back on betasp. It's up to your monitors and post equipment to transcribe the signals. For example, we switch between 16x9 and 4x3 as needed using our aging DXCd35ws camera docked with a betasp deck to record on. We do edit with our Media100's set to 16x9 then output as needed, conforming to 4x3 if needed. We also do the same when we shoot hd (which is also 16x9 format), but that's another story.
