Video– computer video deals with the recording and display of sequence of image each and image in sequence is called fame for a jerk free full motion video 25 to 30 flames have to be displayed per second it is important component of multimedia because it is very useful for illustrating concept that involve movement.
Application of Multimedia
1. Multimedia Application In Education
Multimedia application in education– is used to produce computer based training courses (popularly called CBTs) and reference books like encyclopedia. Edutainment is an informal term used to describe combining education with entertainment, especially multimedia entertainment. The idea of media convergence is also becoming a major factor in education, particularly higher education. Defined as separate technologies such as voice (and telephony features), data (and productivity applications) and video that now share resources and interact with each other.
2. Multimedia Application In Entertainment
Multimedia application in Entertainment- media industry are benefitted by multimedia technology. Images, animation and sound are widely used for making animation movies. A computer is widely used by musicians to record, edit and mix sounds, Entertainment CDs, games, comics and stories for children are used for the purpose of education and training. Video and entertainment films are created using computers and stored on CD-ROM. Music can also using multimedia software packages, such as Media Player (Microsoft), Winamp, etc.
3. Multimedia Application in Marketing
Multimedia can be used for sales and marketing in the following fields:
(a) Information Directory
(C) Buyer’s Guide
(d) Product/Sales promotions
(f) Interactive Catalogs
(8) Merchandising – Point of purchase.
4. Multimedia Application In business
Multimedia has a special role in the field of business, with the help of which the business has a achieved a new position in business , as a result of which customer are attracted to the goods and sale has seen a great boom. business applications for multimedia include presentations, training, marketing, advertising , products demos catalogs, instant messaging and networked communications .
5. Multimedia Application In video conferencing
Video conferencing is another application of multimedia which is gaining great potential. Imagine that you are using a computer and you wish to communicate with a colleague. Video conferencing allows you to see your colleague right on your computer screen and vice versa, allowing you to talk face to face.
6. Multimedia Application of Advertisement
In the area of advertising multimedia will bring major changes it will allow free lions agencies to produce inexpensive tough cuts and prepare clips thereby significantly reducing the dominance of larger advertisement agency.
