DVD Recorder Jitter?

[MeekloBraca]

I am using a JVC VCR, through a JVC DRM70 and into a JVC DRM100. I use the 70 cause of the filters in it, I get a much better product in the end. The problem is with using this JVC VCR is that there is some minor jitter in the final product that isnt there if I run the VCR straight to the TV. I am using the red/white/yellow cables for my hookup. Im thinking maybe run S-video will help?

Any help would be great.

See, the DRM100 has the same filters. The DRM70 is a stripped down version of the DRM100. You've mentioned yours acts oddly in the past, and I can only guess at a defect in your machine, or something unique to your setup that causes undesired results.

Jitter can be caused by any number of issues, from something as common as inferior quality wiring.

I would suggest it is a tape (or series of tapes) that is really in need of a true full-frame TBC. At very least, a unit with a strong sync filter set (such as a Panasonic ES10 record, used as pass-through only).

Such is life, when dealing with video. Good luck.

There is no jitter when running the tape from VHS directly to the TV.

Is your JVC VCR a model with TBC/DNR?
Horizontal or Vertical jitter?

[MeekloBraca]

Dont know what DNR is, i hink its horizontal jitter. But I changed one of the cables to S-video and moved the VCR away from the other electronics and it seems to be going really good.

[davideck]

DNR = Digital Noise Reduction.

You should also try using S-Video cables for all connections. This will minimize Luma/Chroma filtering and may also provide better picture quality.

[MeekloBraca]

Indeed it does. But alas my JVC VCR isnt that good as I thought. The picture control is pretty good but there is a decent high pitched hum from the audio from video in this VCR. I have a 75 dollar panasonic, which doesnt have auto tracking but has awesome audio.

Im not sure what to do about this JVC vcr.

What is the power source? You may need to condition your electrical outlets. Use a UPS with AVR instead of a cheap so-called "surge protector".

UPS? AVR?

[yoda313]

UPS is uninterrupted power supply is my guess - don't know about avr.

But a ups is a seperate power unit that supplies constant power seperate from house power - at least I think thats what it is.

[lordsmurf]

AVR = automatic voltage regulation. This mean the power source being fed to your device will be constant voltage, and will not fluctuate like it does out of the wall.

A UPS is a big surge protector with a battery. If power goes out, your equipment is still on AND was protected from the surge.

[MeekloBraca]

I dont see how that will fix the JVC, when the other machines I have dont have this problem. If it were a consistent problem I had I could see it.

Question.

In the options is says that the AV Compu-Link is on. Could this be a cause of my audio issues?
