Any idea what's causing this audio problem?
 
Getting this throughout the video, does anyone know what might be causing it? I had another camera patched into a soundboard and was still getting audio problems. Plus the pixelation on the video as well. Thought it might be a bad batch of video tapes.

We can't even begin to guess without the reference recording and the description of what equipment you were using and how it was connected.

Here is the link to a sample video of what's happening. Any ideas?

I heard stuttering audio dropouts. And I saw video compression and/or dropout artifacts that were synchronized with the audio hits. This is NOT just an "audio problem". This is a complete signal interruption problem (audio AND video).

Are you saying that you got the same artifacts from TWO DIFFERENT cameras? If that is the case, I would give some credence to the theory of bad tapes. Being tape,(a dying media), I presume that they are not "factory-fresh" but have been sitting around for a while.

Of course you (and ONLY you) can do the experiment with your camera (s) and tapes to see if you can reproduce the problem. It is always a good idea to fast-forward through the whole tape and rewind it just to "exercise" it and break up any possibility for being sticky.

thanks richard, Actually I think those tapes have probably been sitting around. I purchased a pd170 and the fellow had the tapes for sale as well so I purchased a bunch of them. I'll test it with some new ones I have on hand.

Lalo,
Also could be dirty heads. Especially on a PD170. If it's critical there's a company called Sony Media Services
Sony Media Services

That will repair tapes. They did for me over the years. I would work on getting a head cleaning.
