1. Pixel
Pixels or picture elements are represented as small squares that are each a different colour
and position when thousands of pixels are placed to gever they make a digital picture or
image . The more pixels that are in an image the better the quality of the image is .

2. Resalution
Resolution is the clearness and good quality of an image or video . The resolution
depends on the amount of pixels that are used in the image or video the more pixels I
it the better the resolution .The less pixels in the image or video it will be not as good
resolution. Most good cameras resolution is around 640x480 pixels

3. Screen resolution
Screen resolution is used in a ratio format which shows how many pixels can be held
on the screen which you are on. The ratio means how many pixels the first number is
the horizontal pixels the second number is the how many pixels are on the vertical.
When the two numbers are times togever it shows how many pixels are on the screen
The Viewsonic monitor which I am using has a pixels ratio of 1680:1050 which makes
a total pixels of 1764000

4. Frame rate
Frame rate or frame frequency is the amount of frames that are used in a second. The
conman frame rate that is used is 25 or 30 frames per second . Though earlier movies
used 14 to 24 frames per second . And also some new movies like the Hobbit have
used 48 frames per second in their movie . A persons eye can see around 10 to 12
different images in one second .frame rates changes depending where you are in the
world in European video cameras they film In 25 frames per second where as
American they film in 300 frames per second

5. Video formants
There are several different video format types which can be stored into multiple ways
codec , frame rate , frame size, frame aspect ratio , pixel aspect ratio and scanning
meathead. The most common types of video formats are DV, HDV and AVCHD. DV and
HDV are tape based that can be stored onto a disk and be transfer by editing through
a fire wire. AVCHD are file based files that can be transfer to the computer by using a
USB .

6. Composition
When composition a file it turns into a codec which is the progress when a file is
encoded and then decoded when it is played back. codecs do not lose any data
