This isn't a deal breaker, but I'm looking for a way to capture picture only through Vegas Pro 10 from my DVCAM deck, but it appears the DeckLink device settings only allow capture of both video and audio.
Is that indeed the case, or, if not, how/where do I indicate to capture picture only?
I just asked because you lose quality if you ingest the footage via SDI or Component and recompress it to ProRes or DNxHD or whatever.
The only chance to maintain quality is to capture the footage via firewire in native DV or via SDI in an uncompressed format. And if you capture uncompressed you would not worry about some extra GBs of audio.
Sorry - but I can't answer you initial question regarding Vegas. But you have the choice to deactivate the audio channels in Blackmagics Media Express utility. All you have to do is to click on the "1" and "2" below the audio channels to deactivate audio capturing.
