What is wrong with this picture?

[anonjon]

Could you tell me if a TBC would fix this problem? Or would it be more likely to be a proc amp I need?

Thanks for any help you can offer!

Edit: Thanks for the edit; it made sense and I don't know why I didn't do it in the first place.

Explain the path and equipment used. You have two signals there. Field one and field two are each doing their own thing.

[anonjon]

I have a Panasonic AG-1980 going from S-Video into a DV camcorder which feeds into my computer. I record with Pinnacle Studio. Is that what you wanted?

[Marvingj]

The scrolling lines look like some type of AC hum interference. If other tapes play fine on the same setup, then this interference is most likely embedded into the recording.

[anonjon]

Can such a thing be fixed or should I just rip the color out? Will a TBC affect it? Thanks for the responses!

I have a Panasonic AG-1980 going from S-Video into a DV camcorder which feeds into my computer.

'Line in' on the camcorder is a 1/8" mini is it not? (vid and l/r audio)? Have you tried using composite vid instead of Svid to see that resolves the problem?

[anonjon]

No, I haven't. So you're saying the way the audio enters the camcorder can affect the video? The audio does enter through the small headphone jack. I don't believe I have composite video in on my camcorder, just S-Video. I'm just beginning an 8 day vacation, so I don't have access to it, but I'm almost certain I don't have composite. Are you sure that could have an effect, though?

[Dr. DOS]

They I read your post was you are coming off the AG1980 (Svideo) into your camcorder via the 'headphone' type jack. (normally those headphone jacks are composite video) ... the AG does not have Composite connectors (Y/R/W) on the back of the unit?

[anonjon]

well, I'm using a standard S-Video cable from my Panny AG-1980 to my camcorder for video and something like this ( link ) for audio. Does that make more sense?

[Dr. DOS]

OK.... so you camcorder has it's own SVideo In port.... possibly the unit may support a three way cable (Vid L/R Audio) ... in which case you can try coming off the Yel (composite) connector on the panny into the camcorder. (just as a test - to see if resolves you problem)

This will only work if the camcorder support composite vid via the same 1/8 mini plug you are using now.

Have a nice holiday... best of luck

[anonjon]

Did I forget to mention that the Panny doesn't have composite out? It has composite in, but not out.

I want a $200 solution! I want an excuse to buy a TBC! Would that help lock the color where it belongs?

This is what video looks like when I have a PAL or NTSC tape set to the wrong signal output. It's ghastly.

[anonjon]

Any advice on how to fix it? I suppose I could just pull the color off the video, but I'm curious as to whether or not some hardware could fix this type of error. It's the first real problem I've hit and I'd like to do my best on resolving it. Thanks for all of your help!

[edDV]

To me it looks like a field 1 field 2 issue.

Did you say TBC? Someone else posted a similar split field issue and was using a TBC.

Quick test. Bypass the TBC and post a frame.

Does this only happen on part of the tape? every tape?

Oh, dear, I appreciate your help and responsiveness, but as I said, I'm just beginning my trip. I'll try to post a capture when I get back home in a week or so. Sorry guys and thank you!

[anonjon]

here is a snap of the video without TBC. No difference that I can see. Any ideas?

Is this happening because my TBC is only a full-field TBC? Would a full frame TBC squeeze the colors into submission?

[anonjon]

*bump*

[guns1inger]

You need to wait more than a few hours, especially when half the world is asleep.

You have not addressed LordSmurf's suggestion of it possibly being the wrong format. Are you sure that the tape format and the player format match ? I have seen similar from a PAL signal being interpreted by a capture card set to NTSC (why a capture card sold in Australia would have NTSC as the default setting is another question entirely)

[anonjon]

I'm sorry if I violated any rules concerning "bumping". I almost looked up the rules, but thought it might have been long enough.

As for LS' suggestion, I have no idea why a tape in the midst of an apparently NTSC collection shot by the same family would be a different format. I think that's a good thought, but I don't believe they would switch cameras like that. Any way to make sure? I'm open to suggestions on that front, if you think I haven't gathered enough data.

Something I'm really curious about is whether a TBC can correct such color "surfing" / "drifting". Didn't edDV say it was a "field 1 field 2" problem? Would that then and therefore be fixed by a full-frame TBC? My Panny has a full-field TBC, so it only covers field 1 or 2, but not both( I think ), so wouldn't that be a legitimate reason for me to suspect I need a TBC? I'm interested.

Hello all. Was searching through the internet looking for a fix for the exact problem you are having...wavy, red and blue lines through picture. I have 9 of the AG-1980's, 3 of which have this problem. I've isolated the fault down to the Y/C pack in the 1980 itself. Appears that one of the video amp/filter ICs has failed. I'm working on buying a few ICs to see if it's a fix. Have you found anything since your last post. Thanks for any info. Great board here.
