Can Anyone Tell Me What This Is?

So I took my camera to work to shoot the Christmas Parade we are doing. When I captured the footage at home using a JVC HR-DVS3U deck, I noticed that every once in a while during a single frame I get this:

Does anyone know what the pixilation is? I can recapture and it is fine so it isn't on the tape. I cleaned the heads of the deck and I still got it occasionally. I only use Panasonic M tapes. Could this be a firewire cable problem? Any help is greatly appreciated.

Re: Can Anyone Tell Me What This Is?

This is not a pixelation artifact generated by normal dropouts. I think there is a intermittant defect in the player's decompression circuits.(inverse DCT transform processing) Do you ever see this when you playback yr tape through another player?

Thanks for the reply.

This is the only player that I play it back through. I never see it during regular playback when I am viewing the tape on a monitor through the deck. I only see it when capturing to a NLE and then it is random.

Anything I can do about this? Any info is greatly appreciated.

Are you in FCP? FCP users *frequently* complain of this with the JVC deck, but Windows users don't so much.

We've got three of those decks here at work. I wouldn't ever buy one personally. Reliability and design are both very poor in my experiences.

Thanks for all the replies.

I use Avid Xpress Pro to edit with. I've been thinking of trying Premiere Pro so maybe it's an Avid thing.

I bought this deck because at the time I needed a dual deck at it was money that determined which deck to get.

Thanks,
Chris
 
Re: Can Anyone Tell Me What This Is?

Are you running any other firewire devices while capturing? If I capture through the PC into a firewire storage drive, while the input is from the JVC firewire, that happens occasionally. Not often, but now I don't use the firewire storage drive as the capture drive to avoid any glitches. Just an idea.

Try a capture off of the camera over the same area on the tape and see if it still has the problem.
