A Brief Introduction
Hello, my name is Ying, one of members in
this group. My specific topic is digital movie (also called digital cinema),
and it is associated to digital media. The reason that I choose this topic is I
love watching digital movies. Compared to traditional movies, digital movies
make people realize a more vivid and clear world. You may confuse about what is
the difference between traditional movies and digital movies. Now, I will try
to explain digital movies and the different between historical film and digital
film with some contents and pictures.
Introduction of Digital Movies
As digital cinematography has improved in
early 2010s, most of the theaters across the world have converted to digital.
Digital movie refers to the use of digital
technology to allocate signal pictures as opposed to the traditional use of signal
picture film. A movie can be distributed via hard drives, the Internet,
dedicated satellite links or optical disks such as Blu-ray Discs. Digital
movies are projected using a digital projector instead of a conventional film
projector. Digital cinema is different from high-definition television and is
not reliant on using television or high-definition video standards, aspect
ratios, or frame rates. In digital movies, resolutions are represented by the
horizontal pixel count, usually 2K (2048×1080 or 2.2 megapixels) or 4K
(4096×2160 or 8.8 megapixels). Show as the above graph.
The different between
traditional movies and digital movies
A traditional movie is filming by film
camera. The requirements of printing film skill are quite strict for cameraman,
and there is no chance to do the film again if any accident occurs. When
completed cinema package, it still need time to transport to cinema. Finally,
the film will show on the cinema screen by using film, or show to anyone who
has a projector.
On the other hand, digital movies are more convenience
and timesaving. First, it is recorded digitally on HDD (Hard Disk Drive). When
it finished, distributes via parcel delivery. It will not be taken so long to
display by using HDD.
Thus, the cost of filming is really higher
than that of digital movie.
