Hi,

I'm a new user to Vegas 4.0. I would like to capture video using an Osprey 220 capture card (I had seen this on a hardware compatibility list somewhere, but of course can't find it now) using Vegas 4.0. TheVegas 4.0 book indicates that you must use firewire to do this, but I need to capture analog vhs tapes. When attempting to capture video from a vcr, the software records but I can't see a picture while capturing. Only after I push stop and done, does a picture of the video appear in a box. Can anyone help please?

Thanks,
Jon Beedle

To capture analogue source you need a analogue to firewire converter. ADVC-100 is very popular, although I prefer the ADVC-300 for the time base correctio. Gives much better results with older tapes.

You''ll also need something like one of these to drive an external monitor.

The data sheet on this card indicates that it should work with Vegas (at least so the card vendor claims).

I assume you are trying to capture using the Vegas capture utility? Have you tried turning off DV device control? Go to options/preferences and clear the check box on the "Enable DV device control" entry.

It's worth a shot; it's what I have to do in order to get my ADVC 1394 to capture analog correctly.

The Osprey, built by Viewcast, will indeed capture analog video, but it's not designed for this function. Osprey DV was designed to accept an analog feed and convert it to a stream for the web. It's not optimized for correct colors, etc. It's very weak, but it does use the direct show, so it can capture in VEgas. Vegas doesn't support it, it's just a byproduct of how Vegas works. Turn off DV control in your prefs, it will work, barely....You'll do better by doing as farss suggests.

I will definitely make the change in the preferences when I return to work. Hopefully this will work. I will also look into the product mentioned in the first post.

What exactly is the Osprey 220 made for if not to capture analog video? I'm a little confused.

Also, can someone explain why it is better to have two hard drives. I'm having trouble convincing our systems guy to add another one.

Thanks,

Jon

With today's faster drives you can do video on one hard drive some of the time, but it's not suggested and the reason why is that when working with video you are reading or writing a lot of data. A single DV stream is 3.5 megs a second. Two streams is 7 meg, three is 10.5, and so on,

If your data and your programs are on the same drive, then Windows is reading from that drive, Vegas is reading from that drive, any other programs you have are reading from that drive, if you are trying to write video to that drive at the same time, you are moving a lot of data. If one of the other programs causes a bottleneck, the drive won't keep up and you will have a dropout in your video. By having separate drives you are keeping all this data out of each other's way.

The bottom line is if you work with only one drive, dropouts are just waiting to happen. When you evaluate a drive for video you are concerned not with its top speed, but with its minimum sustained speed. It does you no good if your video drive can hit a top speed of 50 meg/s if that is only in a short burst and then the drive drops back to 2 meg/s.

Thanks Buster, that helps a lot.
