This document discusses high definition, 3D, and on demand digital video. It explains that high definition refers to the number of pixels that can be viewed on a screen, with resolutions increasing from 144p to 4K over the years. 3D involves adding depth to 2D images to make them appear more realistic and three-dimensional. On demand video allows viewers to watch content streamed over the internet whenever they choose.

3. High Definition (Alex)
The use of high definition has slowly progressed throughout the years. We have progressed all the way
from the least definitive version of 144p (pixels), all the way to being able to watch a television in 4K. High
definition is basically the progression of the amount of pixels that can be viewed on a screen at one given
time, the more pixels that are on a screen at one time then the higher the definition will be of the thing that
you are watching.
HDTV products were starting to become fashion in the 1980’s, they then became available to the main
public in the 1990’s. Whereas the first 4K television came out in 2014. There are many advantages of
watching things in higher definition is that it helps you see the image clearer and it allows you to see more
detail than you normally would. The only problem with HD is not an actual problem with HD but rather with
the software or technology that the user may be using, such as an older or slower computer which may
not be able to handle HD’s amount of pixels.

4. High Definition
High definition is the amount of LED lights that are shown on a screen at one given time. If you have a
1080p television, then this means that you have 1,920 pixels going down one side and 1,080 pixels going
down the other. Whereas if you have 720p television you would have 1,280 pixels down one side and 720
pixels on the other side. It has never been as advanced as it currently is. Before the 1990’s, films used to
be filmed using actual film reels with something holding them up whilst the cameramen moved them
around. When done filming you would take out the film reel that had just been used and then edit the film.
Although this method is quite old some people do still use it as they like the classic feel of it.
The first film that was digitally recorded and edited was ‘Star Wars Episode I - The Phantom Menace’
(1999). This was all filmed using a digital camera and was then edited using editing software. Nowadays
most beginners who are using digital cameras are using a 35mm camera.

5. High Definition
Nowadays many other people other than television broadcasters are using high definition. HD is also used
in streaming services such as Netflix and many others to allow the viewer to see a clearer image than
what they would normally see. This is done as a selling point for their product, as the higher the definition,
the better the viewing for the public and audience that are watching shows and movies. Another thing that
has been done is that New services have been made through the creation of High Definition, such as Blu-
Ray DVD’s, which are made to give the viewer a better experience as they are better than normal DVD’s
that you could buy. High definition is used as it has no real down-side when it comes to making movies for
the public, and it also allows them to charge higher prices for things such a DVD’S.

6. 3D (Alex)
3D or 3 dimensional videos are considered to be a fairly recent thing, although the first use of 3 dimensional films was in
1922 where ‘The Power of Love’ was shown in Los Angeles. 3D is the use of taking a 2D picture or moving pictures and
turning them into 3 dimensions. Making something 3D is done to give the audience the view that what they are watching is
right in front of their faces, this gives the audience a sense that what they are watching is actually more realistic than it is.
As years have gone on 3D has developed massively. Films such as ‘Avatar’ (2009) and ‘Up’ (2009) have been
complimented as incredible due to their use of 3D. The gross sales for Avatar is $3,020,000,000 which just shows how good
it actually was.
3D is not only used for films, as 3D has progressed it has been introduced into television. For a short while 3D televisions
were becoming increasingly popular, but not much longer afterwards sales for 3D televisions were declining. This is due to
the fact people were complaining that wearing the glasses required got irritating, especially for people who already wore
glasses. Although the 3D television was declining to try and increase publicity Sky released a new television channel called
Sky 3D which only showed 3D television shows and movies to cater to the audience as they felt that there were not enough
shows and movies out there.

7. 3D
Some companies also tried to use 3D in their advertisements to help sell more of their products. An example of this is
Starbucks in 2013. They released an advert in 3D to promote their products; they did this so that the audience would have
the illusion that the product is more realistic, and with the product being right in their face that it may make the customer
want the product more as it is so close to them.
Although 3D has been used very frequently and across different platforms there are also some disadvantages to it; for
example the 3D glasses can sometimes be uncomfortable to wear, they also carry some potential health risks such as
making the viewers nauseous and eye strain.
Most of the advantages of 3D are to the people creating the movie or television show, this is because it allows them to
charge more money for a ticket and in turn generate more profit. The only advantage to the audience is that they get to
experience a production in a different way.
