View Full Version : How Does The Quality Ratings Work?
Flying Dutchman 06-10-2005, 06:41 PM You have a scale of 1 through 10 for picture or video/audio and how does that scale work? I should think that a 1 would be a very lousy picture and sound on a video or dvd and so would a 2 or 3 or 4 but what # is very bad what # is bad What # is fair, so you get what im asking? in other words comlete the #s below for quality.

jasoncole 06-11-2005, 07:18 AM to avoid confusion i made up my own detailed quality guage that i give to anyone who is interested in my shows.i put a lot of thought into it but of course it is still only my opinion.
see below
10/10 perfect (absolute pristine picture,the sort of quality you get from digitally restored movies)
9/10 :very good (standard dvd quality picture that you would get taping a show from tv straight onto dvd in sp.or buying a retail dvd from a reputable manufacturer)
8/10 :good (top quality vhs picture clearly defined with little/no blurrring of the image ,columbia house etc)
7/10 :good/fair (good quality vhs picture the sort you get from dubbing top quality master tapes to sp copies.slight blurring
6/10 :fair (acceptable quality vhs ,picture can still be easily defined but with slightly more blurring.pic may experience the odd jump )

i rather used Grading than the numbers because we is really a 3 rating?-lol Seems Like It's better to give Picture Quality an A or A- or B, B+, B-.

I also use a letter grade rating.
lazygrae 06-11-2005, 01:16 PM The problem with letters and numbers is that it is all so subjective and what one person thinks looks great another person thinks is crap. Jason Cole's system is fine as he's specific, but not everyone follows that exact system or is that specific in the first place. Heck, some people grade the awful looking 7 disc Batman set an 8/10 (I'd say it's more like a 3-4/10). So instead of an opinion "grade" I prefer to just know the specifics: original source, generation, format and recording mode.
So "TV 0 DVD SP" tells me it was recorded off of tv direct to dvd at SP mode.
Or "16mm 2 VHS EP" tells me it came from a 2nd gen VHS film print copy at EP speed. etc.
This eliminates opinion and one knows exactly what to expect. Of course, it doesn't stop people from lying so even this method isn't foolproof. Any additional flaws (bad tracking, jumpiness etc.) can be specifically noted.
combsisthebest 06-11-2005, 01:19 PM Oh that's a really good idea lazygrae! I'll have to implement that one next time I update my tape trading page.

I was shocked that some traders didn't know what I meant when I say that a certain TV Show or Sporting Event is for "DIEHARDS ONLY"-lol

But there's a problem with this type of rating system too - source. I record in very high quality because of my connection (svideo) to my satellite receiver. So when I record 3 hours worth to a single dvd, it's better quality than just saying "TV 0 DVD EP". That rating doesn't really give the person an idea of the true quality of the recording.
I've had people send me stuff recorded in SP mode that was crap. So SP, EP and others sometimes are meaningless.
jasoncole 06-11-2005, 02:15 PM there are also a couple of very important points to consider when you expect a copy to come out a certain way
here are some things that make a difference
1.6/4/2 head vcr's each one reads the picture information differently and will add a certain amount of signal boost to the video output.using a 6 head vcr i have found that i almost don't need a tbc!!
2.poor quality audio/video leads,the cheaper and thinner the cable the worse the result.using cheap cables for the audio output will induce noise into the cable to create bad hissing in the sound and for the video cable the picture will degrade more than it should.
3.the recording vcr needs to have a clean recording head,if this is a problem the picture/sound will be poor no matter how good the playing vcr!!
this is really only true of vcr's although dvd players can experience point number 2
:wave:
BeefyBoyGod 06-11-2005, 05:04 PM I'd call a 10 rating the picture quality a show has when/if it was released on video. What with different shows having a different look, and alot from the 1980s being shot on video to begin with, I'd say that's accurate.
3.the recording vcr needs to have a clean recording head,if this is a problem the picture/sound will be poor no matter how good the playing vcr!!
It's also very important to test the recorded tape on another VCR to see that there are no added problems like tracking or sound glitches, because 9 times out of 10 the recorded tape will playback fine on the VCR it came from, but not on others. If this is an issue, then the Heads on the recording VCR are most likely damaged. I've only found this an issue on Stereo VCRs, so it seems to have something to do with the Hi-Fi audio track.

DVD trading is such a relief, compared to video trading. It gets tiring rotating VCRs to find the right machine for the job, whether the tapes are slp or even sp. :dizzy:

I'm sure when u were a VHS trader that never bothered you. But We get it Jen, you love being a DVD Trader-lol

On the contrary...It always pesters me to have to rotate VCRs nonstop. I do it every day as I'm constantly transferrring videos to DVD.
lazygrae 06-11-2005, 10:50 PM But there's a problem with this type of rating system too - source. I record in very high quality because of my connection (svideo) to my satellite receiver.
I think you misunderstand "source", as the equipment one uses does not factor into this at all. It's just a way of designating what the source material was to get a general idea about the quality to begin with, that's all. For instance, it's safe to assume that a master 16mm film transfer VHS will not look as good as an officially released VHS under any circumstances and that neither of those would look as good as a retail DVD. As an added bonus, if you collect older shows that haven't aired for a long time, "source" also serves, potentially, as a designation as to whether the show is uncut or not.
So when I record 3 hours worth to a single dvd, it's better quality than just saying "TV 0 DVD EP".
You can always define "TV" as meaning "digital satellite via SVHS cords". Or there's no rule that says you can't create a 5th field of info and add "SVHS Cables" as extra info into your grade if you feel it is important. It's flexible, so add as much non-subjective info as you like - it all helps.
The subjectiveness of this "better quality" comment is exactly what this grading system eliminates. It sounds like you are of the opinion that such a video looks really good (when you record it at least) and so maybe you give it a 9/10 on a grading scale. There are other people who are of the opinion that all EP mode DVDs look lousy. So what does a 9/10 tell them? Nothing. What does "TV 0 DVD EP" tell them? All they need to know. Moreover, it does so without turning off anyone who would be happy to get an EP mode dvd (since you can't improve upon off-air quality assuming the broadcast is clean).
I've had people send me stuff recorded in SP mode that was crap. So SP, EP and others sometimes are meaningless.
Generated SP stuff can look worse than low-gen EP stuff, true. But if you split your tv signal (or any source) into two machines and record one at SP and one at EP the SP one will win out everytime. Luckily, "generation" is incorporated into the grading system and taken together, I'd say that the SP/EP info becomes very meaningful.
padre 06-12-2005, 10:58 AM Well, all of this is pretty much just an interesting topic, but not really going to make any overall impact. Traders are going to use the rating system they are most comfortable with. If it is "9/10", "A/A+" or something more elaborate - it's their choice to use or not use that system of rating. Your choice is to trade or not trade with them, and there are tons of other issues other than quality ratings that factor into that. There's no 'enforcement' of common rating standards, nor will there ever be. Mostly because this is suppose to be a hobby, nothing more.

Well, not always. Depends on the quality of tape you use, standard grade or Super High Grade. Super High Grade in EP tends to looks as good, if not better, than stuff in SP on a Standard Grade tape.
Flying Dutchman 06-12-2005, 01:24 PM Lets face it most sources of a DVD recordings are going to be VHS, most DVD sets if not all have the copyguard so its not easy to copy the DVD sets of tv shows, I tried just to see what would happen and it was fuzzy weak picture and fading in and out, I have put tv shows on dvd using vhs as my original source and a dvd copied from vhs recorded at 6 hour was not bad at all of course the 2 hour vhs is a better picture so you get a better copy onto dvd, I guess it depends on your recorder as to the quality of the dvd copy even from a vhs, id give the copys from my dvd recorder about a 7 VHS 6 hour to a 8 1/2 VHS 2 hour, not the greatest recordings but still good to very good and always watchable.
But not even all DVD tv shows or movies you buy in the store or online are good quality, case and point i bought a dvd of rescue from gilligans island from best buy and a dvd of hero at large (John ritter) online and both have factory printed covers but the picture quality of them both are very bad it looks like it was either copied from a bad vhs tape or a vcd, if I would have researched hero at large i would have found that it has not been put on dvd yet and would have known that it was a pirated copy, but you live you spend you learn.
tdubel 06-12-2005, 07:36 PM My 2 cents (agree with Lazygrae and RareTV), I have always gone with the comment, "where is the recording from" meaning NOT vhs NOT dvd, meaning if it was recorded from broadcast onto dvd in SP speed, or I recorded my vhs to dvd, or etc. If I get into a trade, those are good questions to me. AND for the record, Lazy and RareTV have very nice quality and I have learned a little from both. I also like Solomon, will say, I have the series, quality is rough, but for a diehard, it will hold until a better copy comes along.
Now, as for copyguards, it doesnt take much to break them, they are certainly no invinceable.
