MM HardwareEach hardware has its own functions. 1) Scanners are used to convert conventional

images, texts, drawings and photos into digital form that can be understood by the computer.

2) Video cameras: analog video camera and digital video camera (DV).

An analog video camera records video in analog signals on a magnetic video tape.

A digital video camera records video in digital signals, which can be stored in various forms of media, such as digital video tape or memory cards.

MM HardwareEach hardware has its own functions. 3) Camera - An ordinary camera, images are captured on

a roll of film. In a digital camera, images are captured and

stored in a media card. 4) Audio devices - are needed to record

analog sound. The sounds are then changed into digital

sound.

MM Hardware 5) Video capture devices help to

convert analog video to digital video. The fire wire helps to transfer the video

from video camera to the computer. They also transfer digital video to the

computer so that the data can be edited or stored.

4.2.2 Editing Software

04/20/23 10

Editing Software To edit the elements multimedia, we need special

editing software.

04/20/23 11

Editing Software

A text editor is used to edit plain text.

04/20/23 12

Editing Software

Generally a graphic editor can edit images, draw or illustrate pictures or objects.

04/20/23 13

Editing Software Animation

editors are used for producing 2D, 3D, special effects and animation for the Web.

04/20/23 14

Editing Software An audio

editor is used for voice recording or producing music and special sound effects.

04/20/23 15

Editing Software A video editor

is used to edit video.

4.2.3 Authoring Tools

04/20/23 18

Authoring Tools is a program that helps you write multimedia

applications. usually enable you to create a final application

by linking together objects such as a paragraph of text, graphic or a video.

By sequencing them in an appropriate order, authoring tools can produce attractive and useful multimedia applications.

Time Frame Concept

04/20/23 21

Time Frame Concept

With time frame concept authoring tools, the multimedia elements or events are presented and organised along a time line.

This type of tool helps users coordinate when each multimedia element (text, graphics, audio, video or animation) plays.

In time frame concept authoring tools, a timeline consists of layers which span several frames.

04/20/23 22

Icon Concept

04/20/23 23

Icon Concept The icon concept in authoring tools

provides the multimedia developer with a visual programming approach to sequencing events in the multimedia application.

In this concept, elements and events are organised in a structural framework.

04/20/23 24

Card Concept

04/20/23 25

Card Concept The card concept in authoring tools are

based on the idea of card stacks containing graphics, audio, video, text and animation.

Elements and events in card concept authoring tools are organised as pages in a book or a stack of cards.
