"Blu-ray Disc" vs. "HD DVD": Neither Is Winning

[Elie]

Hey Jerry, I don't care how many links you show me, the fact that true HD at 1920x1080 is higher in resolution than 720P at 1280x720 square pixels is good enough for me to conclude that 720P is average in terms of quality HD footage.

Refresh rates will only have an effet on strobing, so the higher the refresh rate, the less strobing effect is caused when you watch sports for example.

Frame rate, again, it's a choice, all movies are filmed at 24 fps, it's a directors choice, as the film look is prefered format for cinema, but again that has nothing to do with quality.

30fps, has the look of reality, like filming from your camcorder. It has it's place in home movies but no where else.
More and more camera's are supporting 24P and you can see examples of their footage online, even at 720P it is great, imagine at 1920x1080 and add progressive on top...I would say it's spectacular.

Movies are being converted today from 32mm to 1080P which is what you are seeing when you go to your local HMV and buy a Blu-Ray or HD DVD movie.

It't the resolutoin that counts, nothing else!

[Jerry Jones]

Elie,

Question for you.

If somebody were to offer you -- free of charge -- a brand spanking new $45,000 Panasonic AJ-HDC27H "Varicam" shown here...

http://catalog2.panasonic.com/webapp/wcs/stores/servlet/ModelDetail?displayTab=O&storeId=11201&catalogId=13051&itemId=94208&catGroupId=14569&surfModel=AJ-HDC27H

...would you turn up your nose and explain you're too good for 1280 x 720 at a true 60 frames per second???

Would you turn this camera down???

...or...

Let's assume you already have a $45,000 "VariCam."

Would you trade it for a sub-$300 Aiptek AHD500 Pro plastic camcorder...

???

You say resolution is everything, Elie.

So let's put your theory about resolution to the test.

As you know, the sub-$300 Aiptek boasts a 1440 x 1080 progressive frame imager.

That's a claim to higher resolution than is found on the $45,000 "VariCam" by Panasonic.

You seem to be suggesting that you would actually trade a "VariCam" for a plastic Aiptek.

So you think resolution is "everything," eh?

Would it surprise you to learn that many so-called 1080 camcorders feature imagers that can't truly resolve 1920 x 1080 pixels?

[Jerry Jones]

Oh, I forgot... you've bought into the 1080 myth.

No matter.

"HD DVD" and "Blu-ray Disc" are as dead as DISC-o no matter how hard you struggle to deny it, Elie.

I think so but also along side resolution, what also counts is compression and bit rates, but I thought it was obvious enough so I didn't mention them.

By the way here is a favorable review in this pocast on the Apple TV. It's about 20mins in.

Elie,

You're willing to sacrifice temporal resolution in favor of spatial resolution.

Seems like a prettty big compromise to me.

Brian, your argument seems so weak.

Video is not film.

This business of trying to use a video camera to acquire video at a film camera's frame rate is not logical in my view.

Film is not video and video is not film!

Wake up and smell the coffee.

My advice to aspiring filmmakers is as follows.

If you want the look of film, then rent a film camera!

Video is not film.

Unfortunately, those of us in the video world have inherited the 24 frames-per-second practice from the film world so that images originally intended for projection in a theatre can now be distributed to people using TV sets.

Did you know frame rate is actually a form of resolution?

It's called "temporal" resolution.

In other words, a higher frame rate means a higher temporal resolution.

I think a lot of amateurs are lured into the 1080p myth because they focus on one half of the resolution equation: the "spatial" resolution.

Well, I do not believe in sacrificing temporal resolution.

I want a full 60 progressive frames per second.

You are willing to settle for less temporal resolution -- 24 progressive frames per second -- so that you can gain spatial resolution (1920 x 1080).

The bottom line, in my view, is that too many people are willing to sacrifice "true life" motion so that they can brag about how "big" their picture happens to be.

Video is all about motion.

Sacrificing smooth, "true life" motion is not a good thing, in my view.

It's a compromise at best.

Those who fall for the 1080p myth are willing to make major compromises and accept motion pictures with lesser overall quality.

High resolution video should be acquired at a full 60 frames per second!

Disadvantages of 24p

24p video has more trouble with high motion than other, higher frame rates, sometimes showing a "strobe" or "choppy" motion, just like 24 fps film will if shot as if it's video, without careful panning, zooming, and slower camera motion. It is therefore not well-suited for programming requiring spontaneous action or "reality" camerawork. 24p can also hurt the credibility of newscasts by making news footage look too much like staged movie clips – though many newscasts do incorporate 24p footage. It should also be noted that while the strobe of 24p is in many ways considered a disadvantage, it's also part of the "film look." 24 fps film strobes in exactly the same way. Most consumer-level video editors (particularly non-HD ones) are designed for 30 frames per second, and the addition of 24p is sometimes awkwardly implemented. Incorrect user settings can result in a 24p frame at the edge of an edit existing on only one NTSC field, thus cutting its resolution in half. If a non-linear editor is incapable of removing pulldown, the standard 3:2 pulldown pattern should be used when shooting.

Future

Next generation digital cinema equipment is being designed to also handle the 48p frame rate along with the traditional 24p. 48p has twice the (video-like) motion (temporal resolution) of 24p, but also requires twice the bandwidth and data storage[citation needed]. However, it is unclear when, or indeed if, movie makers will start adopting the faster frame rate (probably not before digital movie distribution becomes common).

So it appears even members of the film community realize they're going to have to increase temporal resolution (frame rate) as movie creation goes digital. Eventually, 24p may be seen as a relic of the past.

[Elie]

True Jerry about the 24P, but that was the issue all along with film and again has nothing to do with quality.
Strobing is indeed a fact of life with 24fps, but you can counter that with high refresh rae tv's at 120hz.

Film is 24 frames per second. That standard was the approximation of what was defined in the early 20th century by hand crank cameras. And just about every movie disc you can buy is encoded in this format. We're not just talking DVD. We're talking about HD DVD and Blu-ray, too.
How does this relate to an 120Hz HDTV showing frames at 120 frames per second? A bit of simple math tells you that 120 is a multiple of 24, because 24 x 5 = 120. So one of the claims of the purveyors of these sped-up monitors is that they can natively reproduce 24p programming, namely, just about every film has ever been shot.

Again... Blu ray + hollywood film 24fps at 1080P + kick ass 7.1 suround sound + a 1080P TV at 120Hz + some popcorn and soda = an awesome experience!

[Jerry Jones]

It has everything to do with sub-optimal quality, Elie.

I see the problem every time I go to the movies.

I loathe the crippled 24p format because it makes motion look so unrealistic.

It's a compromise of temporal resolution.

1080 @ 24p is no match for 720 @ 60p.

Temporal resolution trumps spatial resolution!

You're paying a high price for a crippled 1080p format.

So which do you think is better, Elie, 24p or 48p?

[Tjalfe]

720P is originally filmed at 24 fps, then converted to 60 when broadcast by doubling frames, you must know that. Your arguments sound more and more like you are on heavy medication

[Jerry Jones]

Tjalfe,

Your claim that sports video shot by ABC and ESPN is acquired at 24 frames-per-second and then artificially processed to be 60 frames per second is not true.

I can demonstrate those networks are recording using 720/60p cameras via the following links:

http://broadcastengineering.com/news/broadcasting_panasonic_pov_cameras/

Panasonic’s ultra-compact AK-HC900 HD progressive scan point-of-view (POV) cameras are playing a key role in capturing the action of the National Hockey League’s Stanley Cup finals on ESPN between the New Jersey Devils and the Anaheim Mighty Ducks. The cameras are also being used for ABC’s live 720p HD coverage of the National Basketball Association’s championship series between the New Jersey Nets and the San Antonio Spurs. ... The 3.9-pound AK-HC900 provides accurate color reproduction in tight places for high-definition sports coverage, television program production, business communications, and government and scientific imaging. The AK-HC900 offers a 720-line high definition output at 60 progressive frames per second, an ideal configuration for sports coverage.

http://www.panasonic.com/business/provideo/news/news04_000.asp

Earlier this year, Panasonic AK-HC900 HD cameras were used extensively during the broadcasts of the NHL and NBA final series, as well as the playoff series leading up to both leagues’ championships. The ABC Television Network utilized the AK-HC900 to capture its on-air talent, crowd reactions and field shots for the HD broadcast of the Super Bowl XXXVII telecast in San Diego, CA last January. For challenging lighting and scene settings, the high-sensitivity AK-HC900 offers extensive gain control settings (-6 to 62dB), a minimum illumination of 0.03 lux, with a high sensitivity of F10 at 2000 lux when operating at 60-fps.

Panasonic AK-HC900 ($28,500) Web page:

Captures high frame-rate 60-fps images for broadcast sports...

Checkmate, Tjalfe.

You really stuck your foot in your mouth when you made the remark that you made below.

This is just too easy; it's like shooting fish in a barrel.
