Video - video types

Question 1

Analogue:

Answer 1

videos that store continuous streams of red, green and blue intensities
o Most analogue videos is recorded framebyframe on tape.

Question 2

Analogue: benefits

Answer 2

can reproduce and represent information exactly to reality as it can communicate subtleties that digital signals cannot

Low cost and portable

wide range of available hardware

has more variation

Question 3

analogue limitations

Answer 3

susceptible to variations in climate, age, dirt, and other feature which reduce quality of audio, reducing accuracy of reproduction: data quality can be reduced during transmission or copying

Analog instruments draw large amounts of power - high energy consumption

analog hardware is less flexible in implementation

Question 4

digital

Answer 4

Video where frames are captured and represented as binary.

Question 5

digital benefits

Answer 5

ease of sharing and storage (due to being able to compress by finding patterns in the data)

data quality remains constant when transferred or constant - higher quality

less affected by background noise (because background noise is analog)

can be easily edited on home/personal computer - keeps quality when edited

can incorporate surround sound, includes a lot of high quality

Question 6

digital limitations

Answer 6

not designed to last very long in storage

lots of digital video formats, and new ones developed which make older ones obsolete and poor-functioning on older devices/platforms that can’ support them
