Capture from Panasonic DV10000 causing timecode stutter

Zulqar-Cheema wrote on 10/12/2002, 5:55 AM

Hi, when I capture form the above machine I notice the timecode stuttering as it captures, it flies for about 2-3seconds then freezes then countinues. This does seem to be when the device is enabled. This does cause loss of frames during capture. If device capture is off the timecode is countinous and no loss of frames occour (up to 1 hour no problems). If I capture from a Sony TRV20 with device mode, the timecode is countinous and again no loss of frames.
Does any one know why the panasonic does what it does and how to stop the loss of frames in device capture, apart from turning it off and why it does it ?
I am capturing on a laptop (1.4 AMD, 512Mb) running XP.

Thansk in advance.

I recently installed Video Factory on my laptop & Im unable to get video in or out of a DV 1000. Can you help me?

I do sometimes have to power the DV machine on and off to be able to see it. Sometimes after a record VV locks up and you have to sitch of the DV machine to free it. Must be a driver issue.

Try the settings by the dv socket on the DV to PASSIVE.

I have the same timecode stutter with my panasonic pv-dc252.

It captures fine with ulead videostudio.

Can anyone help?

Try changing the firewire driver, there are two--- Microsoft and TI.
I use the Microsoft driver with the Panasonic DV-1000 through the
Audigy firewire port with no problems.

How do you change the firewire driver?

Thanks,

We only support the Microsoft DV driver and it should show up in Video Capture's Video menu as "Microsoft DV Camera and VCR". I recommend not changing it...

The issues you're seeing are typical of non-Sony devices (Canon, JVC, Panasonic, others), because there is a known issue with the chipset on these devices which doesn't properly handle simultaneous commands/data over the 1394 bus.

That said, we test several models of Canons and JVC and do not experience dropped frames when capturing from these devices. You may want to check out our Knowledge Base doc related to ensuring successful capture/print:

You can turn off DV device control in the General Preferences to get this timecode stuttering to go away; however you will not have any DV device control, nor timecode available during capture or post capture in the Clip Explorer.

What I should have said was to check to see what driver is installed as
sometimes the "TI" driver is installed instead of the Microsoft driver.
