Hi,

I use Liqiud Pro 7.20 and Win XP SP2  and my HDV-camera is JVC GY-HD201. I use the firewire-port in the computer.

Now I have a problem. If I capture a longer take (more than 5 minutes) into Liquid the video (picture) and the audio go out of sync. The difference between audio and video grows the longer the take is.

Has anyone an idea? What can I do?

Best regards

Martin

Usually the cause is marginal hardware. I can see in your profile it is non-existent...

Hi TVJohn,

 

my computer is:

Intel Core 2 Duo, 3 GHz, 2 GB RAM, 500 GB System-HDD, 2x750 GB Media-HDD (Riad)

with a firewire-port. And I have the AVID Liqiud Pro Box.

 

Best regards

Is it actually out of sync when you put the video on the timeline or just during capture?? Seeing the audio out of sync is fairly common for HDV during capture. The actual resulting capture should be in sync.

WinXP service pack 3 is strongly recommended with 7.2. See if your DirectX 9 install is current.. 

Hi LewS,

out of sync when I put the video on the timeline

Has it ever worked correctly on this computer?

Hi LewS,

I'm not sure, because normally we capture max 1 - 3 minutes takes.

Are you using the firewire port on the BOB or one on the motherboard? Also, in Media Management, are both audio and video going to the same drive?

Is the audio clip now longer than the video, or is there audio missing at the end of the clip? IEEE on the mobo should be tried if avaliable.

I'm using the firewire on the motherboard. What is BOB?

Yes both audio and video on the same drive. In real: two drives with one name.

Now I play first Win XP SP3 on the maschine.

No the audioclip is not longer. I use the firewire on the motherboard.

Martin,

Did you try just recapturing the offending clip?

The reason I ask is I had my first experience of out of synch capture in Liquid two weeks ago after several years using Liquid and more than a hundred tapes successfully captured. I had two tapes out of four on a project out of synch, that had been recorded on two seperate cameras, a Canon XH-A1, and one of my Canon HV-30s.  Interestingly enough the other two tapes were fine, again one tape from the XH-A1, and one from an HV-30. Both were captured from another HV-30 I use as a deck.  The audio on both tapes that were out of synch was off by two frames. This has only happened once in several years with Liquid on several different PCs, and several different cameras.

I assume the two tapes that were out of synch were captured during the same capture session, and the two tapes that were in synch were captured during another capture session. It hasn't happened since.  The tapes are in synch when played in a camera, and test clips captured in Liquid afterwards are now in synch as well.  In my case, it appears I had a temporary "glitch" occur during a capture session and no trouble shooting was needed. I don't know exactly what happened. In editing my project, I used the audio from my Zoom H4N anyway on another track, just deleted the audio from the cameras, and moved the entire audio track for the 74 minute project over two frames.

Maybe just recapturing your tape will work.  Maybe you just ran into a random glitch like I did. Of course, if you've already tried recapturing and the problem is still there, then troubleshooting is warranted. Intermittent problems are usually harder to solve than a consistent, recurring problem. But if it only happened once, then don't waste time trying to fix it. I'm speaking from thirty years of experience troubleshooting laboratory equipment that's often more expensive than my house.

OOps, I just reread your first post. If the problem is still there when you recapture, is it out of synch the same amount each time? I see you mentioned the problem seemed to increase the longer the clip.  Are they from the same tape? Does it happen on every tape? How consistent is the behavior?

Hope this helps.
