Blu-ray Beats Hi-def iTunes in Blind Test

Based on some recent events, the CEDIA technology council decided to conduct a small survey of internal CEDIA staff members.

This is not considered a scientific study but instead a case study that should correlate relatively well to the general public. The survey took place on March 27 at CEDIA HQ.

There were 25 participants who chose to participate in the survey. They were asked to look at two identical displays and answer five questions. The displays were showing the movie "Twilight" playing in 720p via an MP4 download and 1080p on Blu-ray. Both displays were connected using high-quality 5-meter HDMI cables. The participants were not informed which display was Blu-ray and vice-versa as the display on the left was marked "A" and the display on the right was marked "B."

Well duh, of course the disc-based HD medium will win versus compressed crap MP4 from iTunes.

DUH

Real Gambler5495d ago

Remember, there's still tons of idiots who claim that a 480p dvd upscaled, is as good as a bluray!! So basically, there's one born every minute!

I'm still amazed that 8% could not make a difference between an MP4 and bluray...

Sangria5495d ago (Edited 5495d ago )

Well, 8% based on 25 persons, that means they were only 2 to have crap in the eyes. With so few samples, surveys can heavily vary because of one or two persons.

raztad5495d ago (Edited 5495d ago )

Quite a misleading title. It should be read as 1080p BD beats 720p mp4. That outcome is to be expected.

LinuxGuru5495d ago

Even a 1080p digital download would still be compressed and of lesser quality than blu-ray, but yeah the title is a little bit misleading.

walkinghome65495d ago

that video on a blu-ray disc is compressed. The video is not true uncompressed 1080P. What is not compressed is the audio, with most movies using 7.1 uncompressed 192khz 24bit. Even though a blu-ray disc can hold 25 to 50 GBs of data, it's still not big enough to hold uncompressed video the length of a movie.

I believe that uncompressed video is around 128mb/sec. A 5 min music video is around 35 GBs or something stupid like that.

Christopher5495d ago (Edited 5495d ago )

Uhh... actually, it is 1080p. All video is compressed when put onto a media, always has been. Just like how digital audio is never the same as records or magnetic taping devices. The point being that what we have defined as 1080p is on the discs, what it comes from is called 1080 (or greater) uncompressed media.

Now, in comparison to the level of compression of what's on a disc versus what's provided digitally, the 720p is at a much greater level of compression than a 720p or 1080p movie on a blu-ray disc. Otherwise people would be downloading ~4 to 5GB sized files if it was representative of what would be placed on a blu-ray disc for each hour of a program.

walkinghome65495d ago

1080P = 1920x1080
Nothing more. It doesn't mean that it's uncompressed. That's all I was saying.
Yes, all video that has ever been shipped on DVD, HD-DVD, or Blu-ray have codec on the video.

You can have uncompressed video files on disc. They can be in the form of an uncompressed video files. Just like in the recording studio (which I work) you can have 24bit Wave files or 24bit Aiff files.

4:4:4 video is as raw and uncompressed as it gets.

And it can be put on disc just like anything else, but like i said earlier, there wouldn't be enough room. A uncompressed movie file on an harddisk is the same as one on a blu-ray disc. No difference at all. They compress the master with programs like "Compressor" and other things to get it small enough to fit to disc, they do have to compromise video quality a little, not so much with Blu-ray.

Check out this link to learn more about 4:4:4 video if you don't know what I'm talking about or "Google" it.

Why would video run through a crappy compression algorithm ever look better than the disc-based at even an equal resolution? This is basically like comparing CD quality sound to MP3. mpegs are always lossy and definitely don't compress better than whatever algorithms blu ray uses. Digital distributors really need a better way to compress things before they start matching the typical blu ray quality.

Black ops 4, because it was the last cod of duty I was able to dominate with a +2 k/d ratio. Before all the freaking cheating started to happen. It was nice catching people off guard and shooting at them first and getting the kill. Unlike now, where I shoot people first, but they gun me down with less hits, less time, literally feels like they can kill me in a split second. At times, they are able to run away after me shooting them way more than necessary, yet, the second I'm spotted, I'm dead, there's no me running away to cover. They can do cartwheels, summersaults, backflips and gun you down perfectly. They can shoot you across the map with perfect accuracy. They can jump around like morons and gun you down without even having to correct their aim. They have superman split second perfect reactions. That's the best way to describe it, everything they do is spot on perfect. They can spam and spray (no praying) their gun from far away, because they have no recoil or bullet spread. It always feels like I have to aim and also correct my aim when moving around, while these pricks don't have to do the same.

And yes, I know how to play fps games. I dominated many fps games like: Resistance 1&2, kz 2&3, Socom, MAG, Crysis, Gotham City Impostors, blitz brigade etc. all with 2-4 k/d ratio. Kz2 (lag input controls) and resistance (no aim assist in resistance) being the hardest and were the games I reached either close to a 3 k/d ratio or above.

I truly got to enjoy blacks ops 4 and got my money's worth out of it. Afterwords, I would either stop playing cod games after a while, because of the cheating, or would skip buying cod games for a year or two before buying another.

Numbers 6-9 were some of my absolute favorite early gen PS3 games. I'm still bitter about Incognito and Japan Studio.

Goodguy012d ago

The white knight chronicles and infamous games really need to come to modern platforms. MAG I really miss...poor zipper. The ps3 was definitely a unique console despite it being the worst home console of PlayStation.
