I am now able to buy 'regular grade' tape for recording and the results are superior to the recording done before on 'High Grade' tape without HQ. As far as Hi-Fi Stereo goes HiFi IS superior to normal stereo but only if you record music from a high quality source. I have Dolby NR with streeo now and I find the results more than pleasing. If I want HIGH quality sound I listen to a disc. Michael L. Wicks

It isn't that simple. First, there is no exact definition as to what HQ
requires in the way of circuitry. Secondly, much of the picture improvement
attributed to HQ is really due to 1) Better recording technology, 2) Fresh
video heads, and 3) Placebo effect.
I have a JVC 2650 VCR, many years old. I went through three HQ recorders
before settling on a JVC 756. The first HQ recorder had a terrible picture
at EP. The next two had lousy tuners. The 756 is more nearly satisfactory.
The main advance in picture quality is at EP speed, which is now more or less
acceptable on a large screen set, at least for causal viewing. But I don't
think the quality at SP is much better than the old JVC 2650.
My own hit is that HQ adds little to to the quality at SP, at least
on a decent 4 head machine. A two head meachine or EP recording still
needs all the help it can get, but in that case not even HQ can repair
the damage.
BTW, I am fairly satisfied with the new JVC, except for its high $$$ and
lack of automatic Hi-Fi playback, a major cretinism.

It looks like we're both only talking about a couple different VCR machines here. Does anyone else have experience or knowledge of HQ circuitry and its effect on picture quality with other machines??? Michael L. Wicks Sun Microsystems, Inc.

I'm sure the places that make quality > VCR machines add HQ for the 20% higher resolution in the picture quality. I think you have HQ and SuperBeta mixed up. SB truly gives a resolution increase of 20% while VHS HQ merely provides slight detail enhancement. The best HQ circuitry brings VHS up to a level almost as good as standard Beta. Don't get me wrong. I'm not a head-strong videophile who's had nothing but Beta. In fact, my first VCR was a 1977 model RCA VAT400 VHS and I own two stereo VHS decks now as well as two Beta's. The truth of the matter is that SuperBeta is by far the best half-inch format and VHS HQ, HQ PRO or HQ SUPER-DUPER WISH-IT-WAS-AS-GOOD-AS-BETA PRO will never compare. Before the flames come rolling in, I still must admit that for compatability purposes with friends and video rental stores, VHS is the only deck to buy. However, Beta is the the only one I do all my network time shifting with. Just Standing On My Soapbox, Jerry Carathers Tektronix, inc. ...tektronix!tekigm2!jerryc

If you read the article in the same issue about HQ, you will see that Toshiba puts the PRO designation on their top end models which use all four methods of HQ. In other words, Toshiba HQ PRO machines are *real* HQ machines.... Whatever that implies. HQ means nothing without the explanation of which of four(?) types and methods are employed. In other words, with HQ, you may not be getting what you think you are. And to further complicate matters, most VHS manufacturers don't want to tell you or let you know what they are doing. Now, when a beta machine claims it is Superbeta, you know exactly what you are getting.

Sorry Mike, but what you believe to be true does not alter what is true. VHS HQ is a generic name for four distinct circuit/circuit mods in the recorder. Many machines on the market that boldly display the "HQ" moniker have only one or two of these implemented. Perhaps the reason why people have such a wide range of views about how much quality is added by HQ is because the HQ machines they have seen lacked the more expensive HQ circuits. -- Ben Broder {ihnp4,decvax} !hjuxa!catnip!ben {houxm,topaz}/

Whether HQ is an improvement is largely a matter of taste. If you look closely at the picture from your two decks, assuming there's nothing wrong with your Emerson (a questionable brand, in my opinion) you would see that although the signal from the non-HQ deck has more noise, it also contains more picture information. HQ trades off video bandwidth for noise reduction. Some people find the effect pleasing, others do not. Ron -- -- Ronald O.
