Film studios are now selling their movies in HD and Blue Ray. Don't be fooled it's all a scam. it's better just to buy the regular version of the DVD.
I've take numerous film classes and have digital video experience. Basically, 97% of all films are shot using film, 16mm, 8mm. 35mm. etc. And this film is a celluloid and it captures light to form the shapes, but it's basically a thin film composed of cells.


Film cannot be viewed in HD or Blue ray. it simply cannot, why? because HD and BR are based on pixels, tiny light emissions on the screen. Plasma or other LCD technology. So watching a film that was transferred from film, to HD cannot happen. You cannot ever, watch a film that was shot in cellular film..and watch it on HD or Blue Ray. Because they are different technologies. and they cannot match or relate to eachother. And actually transferring film to a computer destroys the original film image.

Solution? well, George Lucas shot revenge of the sith with HD sony cameras. the first of films to be shot using high definition cameras. So when you have your HD TV and HD player, it will look as it was originally shot and intended to be seen.

Studios will now be selling old films like Terminator, Die Hard, Aliens. And tell you that you are watching them on HD. And that is just not true, you are still watching a movie that was shot using original cell film.

So is HD good or bad? it's good..for television shows that are shot in HD and broadcasted in HD. Or future films that will be shot in that manner in the future. But the premise remains, Celluloid, film cannot be sold as High Definition. Blue ray is another matter, it reads the blue color from the films and makes it look sharper, but the fact remains..most movies are still being shot using traditional film and therefore should be watched at the movie theater.

It would be funny to see studios trying to sell movies or TV shows from the 40's and 50's and say that they are in "HD" or "Blue Ray". They will still look very blurry and lacking color. So, the question is..will you still buy product that is advertised as true, but you know it to be false? And I know that I will never see a film like "The Empire Strikes Back" in true High Definition as it was NEVER Shot in HD.

???

Wiki
The name Blu-ray Disc is derived from the blue-violet laser used to read and write this type of disc.


Blue ray is just a storage method, and is called as such because there is a blue laser involved. And if you were going to make any colour look sharper, it would be green, because the human eye is most sensitive to that colour.

With all due respect to Mr Jedi,
as a filmmaker,
I must say you could not be more mistaken...

High Definition technology is the OPPOSITE of what you contend.

First of all... as a video technology, it seeks to emulate what is unique
about film celluloid... namely, the progressive frame rate, the 24 frames a second frame rate as opposed to 29.97 of normal video, and most important, perhaps- the resolution level.

So, as a native format, HD is essentially the video format that looks and acts like 35mm film... that is why STAR WARS, shot on a CineAlta, looks like a normal movie- because HD, at the progressive 24fps setting, looks like film. There are other settings- if you watch your local or national news in HD, it will NOT look like film... because they do not want it to- so they use an interlace, not progressive, frame rate type, and rather than 24 a second, they shoot at 29.97... it still looks great- but it appears to be video, and would not be mistaken for film- like STAR WARS could be.

NOW... as to your point about transferring film to HD...

Again- I am being polite here- you are mistaken.

The advantage of HD over regular DVD is not unlike the difference between VHS and DVD. DVD allowed MORE RESOLUTION of the native film to be seen, with better color rendition as well and digital, not analog, sound.

Likewise, DVD- at 480 lines of resolution, is better- way better- than VHS... but HD-DVD and BLU-RAY (essentially identical) is superior to DVD- why?

Because they offer 720 to 1080 lines of resolution- better than DVD.

Why is this important?

Resolution- that is, pixel numbers... as you mentioned, compose an image. Film does not use pixels, as you said- true. But it does use the chemical equivilant of pixels... a film picture is composed of tiny chemical pixels, if you will.

HD is not a sham product- the movie you watch in HD or Blu Ray CAPTURES THE ORIGINAL RESOLUTION, AUDIO DESIGN, COLOR RENDITION and SENSE OF MOTION (frame rate) of 35mm film...
the medium shot with to make the film.

To see what I mean- buy a DVD of a movie, and an HD version as well. Use an HD DVD player and watch each one onan HD TV (the HD players can play regular DVDs)... so you see a difference? Like night and day.

Lastly- you ask- who would anyone shoot on film anymore?

Well, as ny name suggests- I support the movement from film shooting to HD video shooting.

The reason people shoot on film- which is about 50-100 times more expensive, is because:

a) At this point, it still looks a little better (but that is changing)
b) Some people are purists
c) Some cinematographers do not want to learn a new medium
d) Stars who are vain DO NOT like HD because it requires more makeup and it can reveal age and imperfections with the wrong lighting- film is guaranteed to make a person look better.
e) Studios demand it- there is a prejudice against video because it has looked so bad for so long, people hate it.

Soon enough, perhaps right after Feb 2009 when ALL TV WILL BE HD BY LAW and NO ONE WILL EER SEE an ANALOG TV SHOW AGAIN (set top boxes will change normal TVs to HD receivers, paid for by the government)... soon after that, HD will have been tweaked with software, lenses and other techniques so it LOOKS MORE AND MORE like film.

Within 10 years from now (presuming we all survive 2012)... almost ALL OF THE MOVIES you watch will be SHOT on HD... and they will be projected a the theaters on satellite-fed VIDEO PROJECTORS, not reel to reel film projectors.

HD is not a false product- it is the future, it is the evolution of video, it is the replacement for costly 35mm film, it is the catalyst for a revolution in communications and entertainment- a revolution whereby small, poor Producers, like me, can compete with Hollywood because HD allows for a movie to be made with little money... that fact, COMBINED WITH the new distribution model of the Web... well, it is a huge paradigm shift- as the middleman- Hollywood and distributors- will be eliminated... and films made independently will be watched and downloaded off the Web... in HD format, completing the covergence of film, TV and the Internet... and making any and every web page a potential TV Channel, Movie Theatre, Record Store... etc.

If you are a filmmaker- HD is the answer to the monopoly of Hollywood- controlling what is made, and therefore, what is seen.

If you are a movie lover, HD allows you to watch, in your home, the movie as it was meant to be seen, by using an HD DVD player and an HD TV. It will also give the cinephile many more choices... since the monopoly will be destroyed- and while there still will be star-driven blockbusters made- there will be many smaller films competing... and a few will break out and be major hits.

As the Chinese say- "may you live in interesting times"...

Boy, are we ever... and HD is a small part of this very interesting era we are now living in...

Very well put. Your VHS to DVD analagy was spot on. It's amazing the mis-information that gets put out on the internet.

Put a fork in this thread as it's done.....

For those of you who want to know the truth and not something overheard in a classroom or made up out of thin air....

--------
Digital cameras replace the strip of crystal-coated plastic film with a high-tech image sensor. An image sensor is a seemingly flat surface composed of millions of photodiodes. These photodiodes are essentially substitutes for the individual silver halide grains found on film. Each diode collects light that will end up representing an individual pixel, or dot, in the final image.

The number of pixels necessary to approximate the amount of detail found in an image captured on standard 35mm film is up for debate. Experts in the industry suggest anywhere from four million to 20 million pixels (four megapixels to 20 megapixels) would do the trick.

www.cbc.ca...
--------

So that being said, just about any off the shelf camera with movie mode and pro SLR can shoot in matching quality. Digital film scanners do so at above 24MP. Last I saw before leaving the NAVY was somewhere around 140MP. Way more sensors than silver halides, thus much higher scan than film can capture or display on CRT TV's.

--------
This NTSC format uses a 648 by 486 resolution format. This format makes an allowance for a few additional pixels to be created on the screen edge that may be cut off when displayed. This format is also commonly used by many video compression boards.

Because this format allows you to display a video without losing the "edges" of your video during playback, this resolution seems to be the preference within the industry.
D-1 NTSC

The D-1 NTSC format uses the same standard frame aspect ratio as the NTSC format. Unlike the NTSC format, the D-1 NTSC format uses a 720 by 486 resolution using rectangular pixels.

The D-1 pixels used in the NTSC format are displayed using a vertical axis.
D-1 NTSC Square Pix

This format uses the same standard frame aspect ratio as the NTSC format. Unlike the NTSC format, the D-1 NTSC Square Pix uses a 720 by 540 resolution using rectangular pixels.
PAL

PAL stands for the Phase Alternating Line. This is a video standard used by the color television industry and is the common standard used in Europe. This video signal format sets the video to playback at 25 frames per second which contain 625 lines of pixels in each frame.

There are various divisions within the PAL standard which determine what pixel and frame aspect ratios are used. These formats are as follows:

· PAL (resolution 720 x 486)

· D-1 PAL (resolution 720 x 576)

· D-1 PAL Square Pix (resolution 768 x 576)

D-1 PAL

The D-1 pixels used in the PAL format are displayed using a horizontal axis. This format uses the same standard frame aspect ratio as the PAL format. Unlike the PAL format, the D-1 PAL uses a 720 by 576 resolution.
D-1 PAL Square Pix

This format uses the same standard frame aspect ratio as the PAL format. Unlike the PAL format, the D-1 PAL Square Pix uses a 768 by 576 resolution using rectangular pixels.
HDTV (1280 x 720)

The HDTV stands for High Definition Television. This format is a proposed definition which displays at 1280 by 720 resolution.
HDTV (1920 x 1080)

The HDTV stands for High Definition Television. This format is a proposed definition which displays at 1920 by 1080 resolution.
Film (Academy)

This format uses 2048 x 1536, a standard resolution used for digital film.

--------

Your CRT TV can drift wildly in and out of focus due to its technology being susceptible to magnetic forces. (i.e. polarity shifts, proximity to higher voltage lines).

LCD monitors are different technology all together. They naturally keep the image stable because each element directly represents the same element that was used to capture it.

I watched the latest Batman movie in HD. I was not impressed. Reason being was that I was expecting the film effect that you get when you shoot in 24FPS and I got what looks like straight video shot at 29.97.

I happen to like the film effect, so I'm not rushing out and buying it.

Ya'll do what you want.

Sorry, but either you misunderstood what your teacher was saying or your teacher does not know what he/she is talking about.

Current hi-def television uses 1920x1080 (1080 lines) of resolution.
35 mm original camera negative motion picture film can resolve up to 6,000 lines.
35 mm projection positive motion picture film has about 2,000 lines.
Sequences from newer films are scanned at 2,000, 4,000 or even 8,000 columns.
