Introduction To Videos....

1. What are some advantages of digital video?

• You can upload videos to the computer very easily
• You can edit digital videos on the computer
• You can insert them into other forms of media, for example: document, files
• Digital videos are electronic so you can easily email or copy the video into any device.

2. What is meant by frame rate in video?
In motion pictures, television, and in computer video displays, the frame rate is the number of frames or images that are projected or displayed per second. Frame rates are used in synchronizing audio and pictures, whether film, television, or video. For Example: If a netball match is being filmed, there would be a lot of movement so a lower frame will have an effect of the quality of the video.

3. Are all videos/movies the same frame rate, explain your answer
No not all videos and movies have the same frame rate, they are all different because there would be different number of images being projected per second. There is a different frame rate for videos and movies, for example:
television- 25 fps per second
film- 29.97 fps per second

4. What is meant by resolution, how is it measured?
Resolution is the term used to describe the number of dots, or pixels, used to display an image.
dpi- dots per inch

5. What is the colour system called RGB?
The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography.
