Re: Problem with Canopus ADVC100 capture

For some reason, my Canopus ADVC100 drops a lot of frames
when I capture analog video to my pc.

Unless your ADVC-100 is broken, this is so unlikely that I would
dismiss it as a real-world possibility and focus my attention on
other possible causes of your symptoms.

The video plays fine in the vcr

That.s good.

and looks fine while capturing.

What does that mean? "looks fine" WHERE?
On a TV screen connected to the camcorder?
In a window on your computer screen?

You didn't mention:
What software are you using to capture?
What operating system? Version? SP?
What file format you are saving? AVI?
Whether this EVER worked?
Or if this is a new development?

However, when I play back, there are
missing sections of video and plenty of dropped frames.

You didn't mention:
What software are you using to play back?
How long your tests are?
How many are "plenty"?

Why? It isnt my system (Quad Core, 4GB Ram, SATA striped drives, etc.

Yes, Nice system.
I agree that it seems unlikely that your symptoms are caused
by your computer HARDWARE.

OTOH, I'd bet a nice dinner that the problems are caused
by your computer configuration, software, etc.

You didn't mention:
Anything at all about the software?
What other apps do you have runing at the time?
Networking? (particually wireless networking)
Is this a new problem or did it ever work before?

Also, fiewire out of any digital camcorder is perfect.

Not sure exactly what that means, or how it relates to your
resenting symptoms? Are you saying that if you capture
by playing back a tape on your camcorder, it captures OK?
What happens if you put the analog video into your cam-
corder, used as a digitizing "pass-through" device?

Something is happening during the A-D conversion.

You have not presented enough information to convince me
that you can make that statement conclusively.

The only way around it is to capture the uncompressed video to
my Newtek T4 system through the analog mixer. While this works,
2 hours of video uses 130GB of space.

Does anyone else have this problem with the Canopus?

I don't recall ever seeing a credible complaint about a Canopus
box (including yours, IMHO). It seems likely that Canopus can
ship a faulty unit from time to time, and that may be what your
problem is. But to categorically state that any of the Canopus
boxes is capable of the problems you cite is highly unlikely.
Note that the Canopus boxes use the same chips for D/A and
A/D that are used in many camcorders (perhaps including your
own.)
