A Statistical Comparison of HD DVD & Blu-Ray Reviews

An anonymous reader writes "Gizmodo today posted a statistical comparison of over 300 HD DVD and Blu-ray reviews published at High-Def Digest since the start of the high-def format wars last Spring. Their findings? Overall video quality between the two formats is nearly identical, however Blu-ray titles were slightly, but definitely superior in audio playback, while HD DVD titles had far superior standard def features and moderately superior high-def features."

All that the HD formats really have to offer is that a small percentage of the consumers can view movies at a higher resolution than they could with DVD.

      The only way you could have a non-biased study of this sort is if you selected random candidates, had them watch a movie on your hi-def setup without telling them what format it was (or even know yourself), and then ask them to rate the A/V quality (a crude double-blind study). If you're thinking about investing in one of these formats over the other, take this "study" with a very large grain of salt, especially when the differences are so small.

Sony is currently producing 200,000 UMDs a day and future capacity is expected to be 500,000 per day. Sony expects videos to account for more than 60 percent of all UMD sales in the a few years, with an expected 130 million UMDs being sold in 2008.

      The reason why Blu-ray is credited with 'sounding better' is because many Blu-ray discs use raw PCM encoding for audio, rather than any sort of compression (lossless or not). Some purists believe they can hear the difference between compressed, lossless and lossy compression.

      While many HD DVD titles use lossless compression, not all of them do.

      When an HD DVD title does have lossless compression, its audio is ranked as good as Blu-ray's (and it had better, given that the decoder should be seeing an identical bitstream).

      To be honest, I'm a believer in lossy compression; at the bitrates used in HD DVD, I seriously doubt anybody could tell the difference between lossless and lossy in a double-blind test on identical equipment; the bitrate is well above the level of transparency.

    The bitrate of the lossy Dolby codecs on HD DVD is 1.5 Mb/s. This is well above the transparency level of 1.2 Mb/s for the codec. I wonder if it's a case of subconsciously thinking "this one is lossy, so it can't sound as good," and that a double-blind test would have different results.

    I don't quite understand why they are even comparing sound or video output from a Blu-Ray or HD-DVD disc. The physical medium that the H264 or VC-1 file got read for is totally irrelevant if movies are using the same encoding formats. Features may be somewhat different (though usually analogous), but comparing the codecs seems to be a bit stupid.

    Any differences that actually do exist are more likely attributable to the player or the mastering software than the disc it came from.

      OK, on paper, you'd be quite correct. They all allow for the same codecs, although there are differences about what codecs are mandatory, and what are optional.

      In reality, there are quite a few differences, and good reasons.

      1.) Blu-ray often has an uncompressed PCM track for audio. Whether you can actually hear it or not, there's at least the psychological thing saying that uncompressed is going to sound better than compressed. HD DVD can also do uncompressed PCM, but they choose not to; Dolby TrueHD is lossless (similar to FLAC), but takes less space on disc than uncompressed PCM. Even then, only a fraction of HD DVD's have lossless audio. Most HD DVD's use 1.5 Mb/s Dolby Digital, which is a number of times greater than the bitrate in movie theatres.

      The sound argument is dubious in my head; just like there are people who still assert that vinyl records sound better than digital, there are people who claim that they can tell the difference between lossless and lossy audio. It's not a knock against Blu-ray; they have the room for uncompressed audio, so why not. I just don't buy into the arguments about compressed audio being undeniably worse; espescially at the bitrates that BD and HD DVD use for lossy audio.

      2.) Early BD releases only had MPEG-2 compression available. It wasn't a hardware problem, but a problem with disc authoring software; you just couldn't make a BD disc that used VC-1 or MPEG-4, because the tools to make them didn't exist. The video took a lot more space on disc, due to the efficiencies of MPEG-2 vs VC-1 or MPEG-4, which coupled with uncompressed PCM audio and only having one layer to work with, the bitrate for the video had to go down for the whole thing to fit. And it showed.

      3.) Now that they can produce dual-layer BD discs, and the authoring tools allow for VC-1 and MPEG-4, new BD releases have the video quality that HD DVD always had (HD DVD started out, and is still almost exclusively VC-1, although there are a few MPEG-4 releases). But that doesn't change the 'early' BD releases that relied on MPEG-2, single-layer discs, where quality suffered, and brought the average down.

      There are subtle differences, but for the most part, there's hardly any functional difference. Hidefdigest (the source of TFA) had an article where Microsoft mentioned that they wrote a tool for Warner Brothers that would convert a VC-1 HD DVD to a BD release. This means that Warner makes the HD DVD version, then runs Microsoft's script to convert it to BD. This in turn means that when all is said and done, both formats have the exact same data on the discs, with the only difference being the menu system. So in the end, BD has more space, and costs more to produce. The thing is, few movies would require a full BD, so the advantage of the extra size is questionable.

      And I'm left deciding which I dislike more: Sony or Microsoft. Tough call.

      That's true and false. Yes, if they were the same codecs, it would be the same information. However, its not the same codecs. BD for example offers audio codecs that aren't available on HD-DVD, such as lossless uncompressed full-bandwidth sound (which is better than your local theatre is probably using).

      Also its how you use the codec; you can both use VC-1 but if I have 50GiB and you only have 35GiB to store the data on, I might encode with a higher bitrate and therefore it would look better.

      This isn't rocket science.

    Or you'll get a DVD player that up converts, like a Futureshop in Toronto tried to sell me when I asked for an HD DVD player.

    Oddly, I noticed distinct bias from the manager, who, when I asked again where the HD DVD players were, pointed to the Blu Ray (take THAT, Parent!!). When I insisted that I was looking for an HD DVD player, he eventually told me that the HD DVD player they had was not on display near the HDTV's in the store, like its Blu Ray cousin, but actually on a completely different floor.

    Because of that bias (as well as my own bias in favour of HD DVD -- not a fanboy, just don't like the idea of closed formats dominating markets), I don't go to that store any longer.

  30. Anything with DRM will lose by Indulis · · Score: 2, Interesting

    As more and more people get multiple devices, the push-back against DRM will increase, and move from the small population of early adopter tech-savvy consumers, to the larger population "normal" consumers- once they find that they can't move their legally bought content between their devices they will tell their friends not to buy it. My prediction is that the format with the most easily "cracked" DRM will also be the most popular format & will win.

    Also, having just been through the deep-dive purchasing decision process for a new plasma TV, it was interesting to see that at a normal viewing distance, on a 50" display, HD or good progressive scan DVD produced a similar picture quality to my eyes (HD picture was subjectively about 5% better... this is comapred to 576p upscaled by the TV to 768 lines).
    http://www.engadgethd.com/2006/12/09/1080p-charted -viewing-distance-to-screen-size/

    Summary- at more than 10 foot viewing distance with a 50" plasma screen there is no benefit to more than 576 lines (us PAL types are in luck here). About 13 foot for NTSC 480P. So for 42" HD is probably a waste of time everywhere. For 50" it is more useful in NTSC territory as long as you sit fairly close up, and marginal for PAL territory.

    Also, I saw one HD feed split into similar sets from the same manufacturer, one set was 1080 line the other 768 line. At normal viewing distances no noticable difference.

    As usual, most people comment without reading the article.
    The summary is quoting the article, but not the explanation.
    The audio advantage seen in the blu-ray is about more audio tracks with better formats (or even uncompressed audio), not any encoding/decoding difference.

    BD is using its additional space to offer more audio tracks.

    On the other hand, the interactivity feature is mandatory on HDDVD and still developing on BD, so the HDDVD gets the edge there. So, those are not so much qualitative judgements as more of a snapshot of the current state of affair. BD leads with better storage (expected) and lags with their BD-java that is not quite understood by the studios yet. As time go, BD should retain the audio advantage while negating any interactivity advantage of HDDVD (provided that both tech should be about equal).

    Nothing really surprising here so far. The bigger sale number of BD *is* surprising though, as the player that sold the most *IS* the PS3. Those numbers are showing that people use it as a video player, as Sony had planned.

    Only the futur will tell us if this will give them the dominance in video players at the cost of video games and especially if that sacrifice was indeed a paying strategy.

A standard two hour movie will fit on a DVD5 at 720p with 6 channel AC3 audio and a bitrate of 4.5-6 mbit/sec. While this wouldn't look great using xvid, H.264/AVC High profile can create great quality. x264 using Sharktooth's HQ-Slowest profile is very impressive. A 2 hour movie can fit on a DVD9 at 1080p at 7-8 mbit/sec, again with very good quality.

    I disagree with the analogy here between HDDVD to Blu Ray :: DVD-A and SACD.

    DVD-A and SACD had/have their issues due to a number of reasons. SACD is Sony, and that is enough of a reason for failure (even with a Sony receiver and a Sony SACD player it takes separate wires to play a SACD than a CD or DVD, dumbasses*).

    Also HD CD formats are not backwards compatable (mostly) with existing technologies like MP3, regular stereos and car stereos.

    Now, HD video is going to take off in some way. Why? DVDs and SD content don't look very good on your brand new HDTV. 1080[ip] and beyond content will blow you away compared to SD stuff. Even non-technical people can tell the difference between HD and SD, but most people are not that tuned towards audio. I guess it has to do with 1/2 of the human brain going towards vision or something like that.
