- You can store it easily on a computer. You can transfer easily with a usb cable.
- You can easily edit.
- If you copy, you don't loose any data, no generation lost.
How many framers per second.
3) Are all videos/movies the same frame rate, explain your answer.
No, because some movies have poor quality compared to the rest. The higher the number of framers pers second them ore smooth it appears.
4) What is meant by resolution, how is it measured?
The more resolution the more sharper the image can appear. The measurement is how many pixels across and how many pixels down the computer screen.
5) What is the colour system called RGB?
RGB stands for Red Green Blue. This means that every colour has a mixture of RED, GREEN OR BLUE. This allows all the colours to appear.
6) Explain the video standards PAL, NTSC, and SECAM, what are the main differences between them?
PAL: Is short for Phase Alternate Linen, it is an analogue television encoding system that can be used to broadcast television systems in other parts of the world.
NTSC: It is named for the National Television System Committee and it is also an analog television.
SECAM: This is Sequential colour with memory, this is also an analog colour television.
The differences between them is that they are all used in different parts of the world. The difference is also the number of frames per second.
7) Which standards do we use in Australia?
In Australia we use PAL.
8) What is an IEEE 1349 port?
This is a port that is able to connect devices to your personal computer.
9) Why do digital video cameras use video compression?
This is used to reduce the size of the data in digitalised frame or series of frames for a video or audio. This makes it easier to transfer and to send.
10) Describe what a codec is?
This is a term used for compression/decompression. This is when a computer program is able to shrink images or files and make them suitable for the use of a computer.
11) What is meant by "generation loss", where does it happen?
This is when the quality and potential increase of file size between subsequent copies of data are then lost. Anything that reduces the quality of representation when copying can be considered a form of generation lost.
