Hi Dan,
We haven’t talked much about DV support in Vegas as we primarily work with uncompressed 8 and 10-bit material. You can capture to uncompressed 8 and 10-bit in Vegas but you can play out any of DV or uncompressed 8 and 10-bit to tape or your broadcast monitor.
You are wanting to capture to DV and that is not currently possible. However if you also have Premiere Pro 1.5.1, you could use it to capture to DV from the DeckLink card and then you can drop that DV file in to Vegas and it will not require rendering. DV files from other sources may well require rendering so it’s nice to avoid that if possible.
I’m not sure whether DV capture in Vegas would require updates to Vegas or the DeckLink drivers or both. However I’ll place a request with the engineers as it would be nice to do this if we can. Meanwhile hopefully the capture with Premiere Pro will work for you.
Regards,
