Lately I've seen a lot of double (and even triple features) combined onto a single BluRay or DVD.
Do these film packages have the same quality as the single disc versions? I wonder if squeezing two, or three films on a single disc requires a degradation of quality?

Firstly, it depends on the quality available to make the DVD from. For example, on my recent tripto the USA I bought a box set of 50 movies - 3 or 4 on each Dual-layered DVD...but the quality (Public domain movies/TV shows mostly from the 60's and 70's, with a couple of 80's entries) probably wasn't that much to shout about to beging with. That said, they are perfectly watchable.

Also - I know of few cases where a dual-layered DVD is completely full....most - with extras included - still leave a good Gb or so's worth of free space...even on so-called "Superbit" releases there was still room to spare. So it does not nec essarily follow that two 90-minute movies on one disc leads to poor quality...it might just be using up the space on the disc. I do, for example, have another set of 12 movies on 4 discs where the quality is surpringly good...with full DD sound for some of them...look great, even on a 42" LCD TV...and was VERY pleased (again, on my USA trip) to find "Impostor" released in this format (it's a toughy to get hold of)...looks and sounds top notch.

...but, then, I guess there are the cases where they are squeezed on and quality sacrificed for the sake of a quick and cheap sell...though I have not experienced any such release as yet, personally.

If it is a flipper it would not degrade the quality, otherwise, yes you have a compromised bitrate more than likely.

As Mr Greg said: it depends!

Often it means they are coded at a lower bitrate: the same as when they fit five episodes of a TV show onto a disc instead of two or three. On the other hand, the recent Quatermass double-feature DVD fits two movies with mono sound and no extras quite comfortably. Similarly, it depends on the original single disc version. For instance, the BD encode of Part I of Ben-Hur takes up about 35 gigs of space on the disc; compare that to, say, Upstream Color which only takes up about 10 gigs. The latter could easily share a disc with another film, but the other would have to be compressed significantly to fit another movie in.

Thanks for the feedback. That is what I suspected. It's frustrating that there are no "standards". DVD's are supposed to have better quality than VHS, and BluRays better quality than DVD's. I find some upscale BluRays look worse than their DVD counterparts.

I was looking at some bargain discs like the BluRay that has "2001, The Shinning, and Clockwork Orange" in a single BluRay package. ( I assume their on one disc) Also many Roger Corman films have been packaged as "Double Features" on a single disc. I'm not sure if they are flippers or not.

Those are three discs - repackagings of the discs that have already come out. I have one that groups The Goonies with the two Gremlins films.

Solium,

Blu ray, done professionally, is a wondrous thing for such a low price. Now there are always bad source prints, bad mastering etc, so you can always find ugly blu-ray. I can burn a DVD or VHS copy to Blu-ray, it certainly will not be 1080p just because it is on a BD. I would say you should read the back of them, otherwise just get the one disc version of the film, preferably at somewhere reputable.

Thanks for the additional information. I should have mentioned the titles I was looking at in my original post.

I think you are wrong. Both DVD and Blu-Ray have very specifically defined standards.

But both are at the mercy of the quality of the source material, and how they are compressed.

Most of the quality lables (Warner's for instance) will simply package 3 or 4 Discs (titles) in one package for better sell-through later on down the road. Multi movies are not necceassily squezeed onto 1 or 2 discs. I was concerned about this myself, but all the 'multi" packs I have obtained have their contents on separate discs. It can be a good way to save money on lesser titles you may want.

Then what are the BluRay standards? If you can just upscale a film onto BluRay then BluRay is just another carrier device. Films are either too grainy or to much DNR is applied. Many films are not cleaned up at all. Specs and dust flutter on the screen like it's snowing.

Edit: Let me clarify, there are many excellent BluRays out there. I'm not dissing the whole medium.

I was also surprised to find that that particular set is a three disc package; apparently the same editions, extras and quality as the standalone releases. Just got it myself; great deal for these essential Kubricks. The transfers of 2001 and The Shining are stellar. Haven't viewed 'Clockwork' yet, but I understand it looks about as good as the source elements allow.

If you're curious about a particular release, many websites will list number of discs in a set. Or you can usually find that info with a UPC # or Amazon's AISN...

@ Cooper- Thxs a lot! Really surprised it's not a cheapo package.

Another interesting case was the John Carpenter: Master of Fear, 4 film set, which did feature two films per DVD; each on its own layer, and each being a remastered edition that bested previous releases on the format...and that included those that might've been on dual layered discs of their own.

Those titles are gradually being released on Blu-ray: The Thing and They Live are already out, Prince of Darkness is coming...and Village of the Damned is probably an eventuality. But for now, the Master of Fear set is the best looking source for POD--for a few more weeks, at least--and Village.

If you are talking about quality standards of the material to be transferred, then there are no standards, like there never were for DVD, VHS, Laserdisc, etc.

No problem; I once passed this set up for $9.99. Eventually jumped on it for twenty bucks...and still a great deal.

Yes, but again, this can be down to the source...for example, the Aliens Blu-Ray is superb transfer, yet retains a lot of the grain because it's just the way it was filmed - it's part of the movie...but that's not to say that it doesn't look great.

Another case to consider is Predator where in my own humble honest opinion, the DVD I have (was a cheap and cheerful 2-Disc set coupled with the sequel) looks better than any of the Blu-Ray releases.

Blu-Ray has the potential to look better then DVD. It's specs are clearly far superior. But at all depends on the source material, and how it's handled.

I know it comes down to the source material and how it's prepped. But I don't recall films earlier on VHS looking worse on DVD.

BluRay by it's nature requires special attention because it can greatly magnify what is subtle in standard definition. People say film has grain, yes that is true, but in many cases the grain is magnified in the process. More so than the film itself or its theatrical presentation.

Sorry for opening up a can of worms. I really derailed my own thread! embarrassment

Well some films did look as bad or worse on DVD -- because they were sourced from VHS or for other reasons.

And I think, for the most part, the manufacturers have learned what's okay with their releases. You still hear about the occasional snafu, the occasional catalog release that's obviously sourced from an older transfer, but you hear less often now than a couple years ago about films DNRed to death, and you hear much more often -- both with catalog releases from Sony, Disney, etc and from prestige distributors like Criterion, Twilight Time and so forth -- about the time and care put into 4K scans and painstaking remastering processes. I almost always take the time to scan the review sites and forums -- Blu-ray.com, the digitalbits, etc -- in order to screen out and horrible BDs, but for the most part I think they've gotten pretty good at realizing that the kind of consumers who have upgraded to BD are the kinds of consumers who really care about top-notch presentation.
