Can I combine my DV cameras TBC with Canopus?

[DieselsDen]

Capturing video with my camera results in audio sync problems. I would like to use the Canopus 100, but also I need a time-base corrector for my VHS tapes.

Can I use the Canopus with the camera so the VHS tapes are time-base corrected before they are captured into AVI files with the Canopus?

VHS Player > DV Camera (pass thru with TBC) > Canopus > Computer

Thanks for any input!

Sure you can!

But you will be reducing your canopus 100 to pass-thru only
ie it's acting as a cable extension
it makes sense when you think about it

the canopus 100 converts vhs to DV whichs goes into your pc via firewire

the DV camera converts vhs to DV which means you would just put that into your pc

[DieselsDen]

I understand. I just wondered if there would be any problems with adding more "processors" to the capture.

The Canopus is to lock the audio and video so that it stays in sync, while the DV camera acts as a time base corrector.

Anybody know of any potential problems?

Thanks again,

no no
the canopus PASSES the video through - without touching it
no audio/video sync - nothing it is jsut passing the DV signal when you connect a DV cable to it

it only starts converting and locking audio to video when you input from composite or SVHS inputs

[DieselsDen]

Ah, ha! I got it now.

Damnit. That means I have to use the analog out of the camera into the Canopus to assure a locked audio and video signal.

Which also probably means a reduction in video quality!

Right?

yeah - although the TBC on the camera will go a long way to assuring audio sync
unless the vhs tapes you have got are REALLY bad condition the camera's TBC should be ok

[DieselsDen]

Thanks for your input. This whole video capturing and DVD burning process is driving me batty, especially with the audio sync issues. I've searched the majority of the threads, and it appears as thought the Canopus is the easiest way to cure the sound problems.

If you are using type 1 DV avi files, a DV camcorder is pretty much always in sync. I have never had audio sync issues with my Sony TRV-25 miniDV camcorder.

See this link:

Unfortunately, through my two Sony Digital cameras (TRV 320) and TRV 340, the sound loses sync approximately on hour into the 1 DV capture. And since the Canopus does not lock audio through firewire, I have to figure some way to get an analog out of the camera (so it can time-base correct bad tapes) and into the Canopus. What a pain.

Thanks for your response.

Strange,

I have never heard of anybody else with this audio sync problem. I wonder if it be related to your small hard disk. I personally use a separate hard disk partition for capture.

[DieselsDen]

Actually, there are many posts here which also talk about audio sync problems while capturing through a DV camera via firewire.

I have a separate 80 gigabyte hard drive which I defrag everytime I capture. There is plenty of space available, and I never had any problems with it before.

I don't want to argue with you but I haven't found the threads that you are talking about. On the contrary, I have found threads that mention that out of sync is never an issue with a digital camcorder:

Somebody else using the TRV-340 has no problems:

Whenever I capture through Windows Movie Maker, I get the sync problems. Is there any other program that allows 25 Mbps analog to digital conversio via a DV camera without the sync problems?

Thanks!

You can try DVIO and see if it helps:

I personally use Dazzle DVD complete program to capture and TMPGEnc to encode. I somehow doubt that the software is the problem but you can try DVIO to verify this. I wonder if it might not be your firewire card or cable or something else. It's hard to say. Perhaps you can try on somebody else's computer to see if you have the same problem. Perhaps you should also try encoding the DV avi file to mpeg to see if it's not just the DV avi playback that is affected.

As you can tell, I don't really know. Perhaps you should start a new thread to ask about this. Other people may have had similar issues. I never have had it and I know that most others haven't but there must be a person that has had a similar problem that can help you. Best of luck. Sorry, I can't help you more.

The only out of sync issues that I have had were caused by the mpeg encoders in Dazzle DVD complete and Ulead DMF. I now use TMPGEnc to encode to mpeg and no longer have these out of sync problems.

I remember reading that frame drops upon capturing DV can create out of sync issues. You are not suppose to drop frames with DV (I never have) but if it happens, I think that it might cause out of sync issues.

Try also Ulead Video Wave Version 5 ( if you can get your hands on this software). Real easy to use and I haven't had any sync problems with my Sony (I'm using Sony Digital Camera/Firewire/Ulead Video Wave 5).
