Short films are usually
seen as small budget
amateur films lasting
only a few minutes.
Short films can be
made by both
independent film
makers, big budget
studios or even
anybody with a video
camera and YouTube
Account.
Definition

The Internet - A large portion
of short films are created for
the internet. By definition any
video on the popular media
website YouTube is a short
film.
Cinema – Some short films
are created specifically for the
cinema by film makers. This
has become increasingly
popular by animated film
creators. However other
creators tailor their films
specifically for short film
festivals, please see that page
for details.

There is a large
following for short
films throughout the
world.
Just like with feature
length films, there are
a series of film
festivals for those who
make short films. One
of the biggest of which
is in Cannes.

Presentations –
Presentations are a key
part of promotional
videos. They can
easily be used by
management within a
company to cheaply

Film Trailers are
defined simply as a
video that advertises
an upcoming movie
using footage from the
film.
Definition
32. Back
The Internet – The internet has become a growing
force for promotion over the last few years. As
such more and more film trailers have been
appearing online on website such as YouTube.
This is a very cheap way to broadcast a fil trailer
because you rarely have to pay to put them online.
However there is always the chance people will
skip past them. Not only is the internet
cheap, people are more likely to share the trailers
they like with their friends thus reaching a much
bigger audience.
TV –The TV provides a captured audience for film
makers to show case their trailer to and therefore
they choose TV to entice people to go see the film.
However TV is an expensive platform to advertise
on and so there are always only a small number of
showings on TV for each film
Cinema – The cinema is still the most well known
place for people to see film trailers. They are
usually shown before a movie starts to wet viewers
appetite and get them to go to the showing of that
film later on.
DVD, CD, Blu-Ray – All of these are also usually
likely to contain film trailers, this is especially the
case for DVD’s where just like in Cinemas there
are trailers for upcoming films. Once
released, these trailers never change which is good
because it will always direct viewers to watch
those film.

The Internet – The internet is the
main source of Web 2.0, more
specifically websites such as
YouTube, Facebook and Twitter have
been the driving force behind it. The
reason for this is that they actively
encourage users to upload as much of
their own content as they can.
Mobile Devices – Mobile devices are
also leading the way for Web 2.0.
The reason is that current gen
smartphones are linked to the internet
meaning that users can watch, create
and play content that they or others
created. With the use of smartphones
it even allows for users to create and
play their own games.

Viral Marketing –
Viral Marketing is a
technique where the
marketing is done
through word of mouth
or by sharing of the
advert by consumers.
Definition
38. Back
The Internet – The internet is
the main source of viral
marketing. Typically a company
will release a video, image or
sound onto the internet either on
it’s own dedicated website or on
a social networking site such as
Facebook or Youtube and let
consumers share it with their
friends.
Mobile Devices – Mobile
devices are also part of this
phenomenon because they have
access to the internet therefore
allowing the owners to access
the marketing. They also allow
the owner to take a photo and
share it if the viral marketing is
in the form of something
physical like a flashmob.

example of viral
marketing. Coca Cola

defined as a method of
showing off a product
in such a way that the

it.

•
The Internet – The internet has become a growing force for promotion over the last few years. As such more and more adverts
have been appearing online on website such as YouTube at the start of other videos. This is a very cheap way to advertise a
product to customers. Not only this but advertisers can pay websites to target their adverts at the correct audience such as
females in a certain location. Google for example will target advertising for what you like to look at on other websites. The
internet is a cheap method of advertising.
•
TV –The TV provides a captured audience for companies to showcase their products or services. However TV is an expensive
platform to advertise on and therefore it is important that adverts are targeted and played at specific times when the best match
to their target audience is watching. Such as middle aged women at half 7 when they want to watch Coronation Street.
•
Cinema – Cinemas tend to have advertisements on before a film. I suspect a cinema to be a cheaper place to advertise in
comparison to the TV as the audience is smaller though they are just as well caught.
•
DVD, CD, Blu-Ray – All of these are also usually likely to contain film trailers which are a form of advertising, this is
especially the case for DVD’s where just like in Cinemas there are trailers for upcoming films. Once released, these trailers
never change which is good because it will always direct viewers to watch those film.
•
Mobile Devices – Mobiles have long been a target for advertisers. More specifically they tend to advertise on apps that users
download. This is a cheap method of advertising that captures an increasingly young and impressionably audience.
•
Kiosks – In technological countries such as japan, interactive advertising has appeared on kiosks where they sense who is
coming near and attempt to show an advert likely to attract you. For example in some clothes shops there are interactive
mirrors that show what customers would look like in certain clothes. Effectively advertising to customers from even the most
intimate places as a changing room.

The Internet – The internet tends to
be the most common place for virtual
reality tours. The most commonly
used of which is Google Streetview
where users can walk around a street
almost anywhere in the world.
Housing companies also tend to use
this interactive feature to show off
the insides of houses.
It’s done through the stitching
together of large panoramic photos to
create a 360 degree view.
Mobile Devices – Most smartphones
have access to these websites or
indeed their own apps which allow

Games – A game is
defined as an activity
that a person
undertakes for fun.
Definition

The Internet – Certain games can be found an
played online. These games tend to be free and
small.
Mobile Devices – Mobile devices have come a
long way in recent years but have had games on
them for years. They started out as small games
like those usually found online. However since
the invention of smartphones have blossomed to
become a big business of interactive media with
literally thousands of different games available
to users. These games range from 2D platform
games such as Mario to massive 3D
metropolises like GTA San Andreas which is
available on mobile devices.
DVD, Blu-Ray – These are what most people
think of when somebody says games. Games on
disks are usually played by either PC’s or
consoles. These games too have expanded in
recent years to become a massive business.
Recent games such as Grand theft Auto V have
given players access to locations the size of real
cities to play with how they like. Games are big
business and are the pinnacle of interactivity.

cooking. One user might create
and share a video where they
take viewers how to cook a
meal.
Mobile Devices – Mobile
Devices link in heavily with the
internet here as they allow users
to access E-Learning sites on
the move meaning that in theory

Digital Video Capture
– Is the method of
transferring a video
from recording device
to the computer.
Definition
54. Back
• The process of capturing digital media from a camera can happen in any of a
small number of ways:
• Firewire / cabled capture – One of the easiest ways to capture media is to connect
the device to the computer via a cable and transfer it that way. This is either done
through software provided with the camera at purchase or through accessing it’s
memory through the computer and copying the files across. Suitable for those
wanting fast downloads to computer.
• WIFI – An increasingly popular way to get content off a camera is via WIFI or
even in some cases an inbuilt 3G option. This usually uploads the content to a
remote server such as Dropbox for the user to access later. This is suitable for
those on holiday and allows the user to delete the data off the camera as soon as
it’s uploaded.
• Memory Card – Certain cameras will take memory cards such as SD Cards and
will save the data onto those which can be removed and inserted into a computer
to download the data off. Suitable for use at events where you constantly need to
be recording but don’t have enough space on a single card.

Compression – This is
what is done to make
file sizes smaller in the
conversion process.
Definition
59. Back
Compression comes in two distinct types. Lossy and Lossless.
• Lossy – This is where the compression of a file makes it smaller
through the removal of data. The sections it removes are small
enough not to be too noticeable, depending on the file type. This type
of compression is usually used for anything that will be put online.
This is because a smaller file downloads and streams much quicker
than a larger one and as such a lossy compression is needed at the
loss of some quality
• Lossless – This is where the file is compressed but without the loss of
anything from the file. These files are usually bigger as a result but
however do tend to be much better quality. These are usually used in
cases where file size isn’t too much of an issue but quality is. Such as
on DVD’s or Blu-Rays.

When you download
things off the internet, the
item is downloaded at a
certain speed. Speeds are
measured in a scale known
as ‘Bits Per Second’ (bps).
What’s the scale:
1000 bits = 1 kilobit
1000 kilobits = 1 megabit
1000 megabits = 1 gigabit

File Size – The file
size is how big the
overall file is. Usually
in MB or GB
Definition
75. Back
The size of a file
defines many factors.
Firstly a smaller file
usually means lower
quality content
because it needs to fit
into a smaller package.
However, bigger files
take longer to
download / copy.
Therefore a balance is
needed.

Aspect ratio is the
relationship between the
height and width of the
video.
It is usually expressed as
two sets of numbers
separated with a colon.
Such as (8:5).
It used to be used to
describe the size of a
video feed. However
nowadays it has fallen
out of use due to modern
TV’s and films all being
made to roughly the same
aspect ratio.

DRM is used in several ways
for different media type. DVD’s
tend to just lock the contents of
the disk making it near
impossible to copy the disks.
For games however the content
can be locked in that way or
through the use of locking
features within the games and
forcing users to use single use
codes within the games making
sale of the games pointless.
Companies are finding other,
less invasive ways to have
DRM. A games company called
Valve sets the DRM as it’s
games program locking the
games to an individuals account.
Meaning that the user doesn’t
notice the DRM and making it
less intrusive.
