Does VV3 do analog capture well?

I've seen recommendations on getting the Canopus device to daisy chain of a firewire port, but I wanted to know before I tried this product, can it do video capture?

I have a BT878 based analog board and want to get away from Video-for-Windows applications. I have the WDM drivers loaded for this card and every other program I've tried gives me A/V sync issues on long captures (over 1 hour or so).

Does VV3 accomdate for this drift in the PCI bus/clock between my capture & sound cards?

I don't have the Canopus unit, but i use a very similar device from Sony. I've regularly performed captures in the 2 to 4.5 hour range and never had any sync problems at all. You won't use your sound card for these captures; both audio and video will be captured as a single DV stream through the firewire port.

Thanks. But does VV3 have an interface to capture via an analog capture card at all??

The Canopus ADVC-100 interfaces to the computer via an IEE1394 connection and is recognized as a "AVC Compliant DV Tape Recorder/Player" under Device Manager. (In other words, it converts an analog input into a DV AVI stream)

dcran: what other video apps do you have installed? Roxio/MGI maybe?

(bangs head against wall) Forget the Canopus. Does VV3 have the ability to capture via an analog video capture board?

You can capture with some analog capture boards but you may run into trouble- much is dependent on the driver. Can you see the capture card driver as an option in Video Capture? (even the demo will tell you)

DV is your best bet in any case. The Canopus ADVC works well and there are no a/v sync issues if you capture DV.

I've used Vegas' Video Capture with both the ATI series cards and the WinTV card. I know these are both based on some BT chipset, possibly the 878. It worked with both of them, but not wonderfully well. The results with the WinTV were much better than with the ATI.

I've used Vegas with a BT878-based analog TV capture card and I must say that it works but not so well: there's one big limitation: you are not able to use any software compression codecs (Vegas Capture doesn't have any way in its interface to access the VFW/DirectShow compression codec/filter selection box) so you are stuck with uncompressed YUV 20 MB/s video.
I forgot: I didn't experienced any serious audio-video sync problems (with a SB Live audio card) but I didn't do any long (i.e. more than 4-5 minutes) captures.
