production of multimedia applications Production of multimedia programs Steps to produce multimedia

applications

The world has witnessed in recent major development in different fields of science, and especially in the field of information technology and telecommunications , and information technology developments have focused on how electronic information storage, processing , retrieval and display and transfer fast and secure way to take advantage of them when needed .

Definition oF Multimedia

Integrate a range of digital information with digital in different shapes such as text , graphics , animation ,  images ,  audio , and video clips in one application for the user to view the interesting and enjoyable way to achieve certain goals.

Types of Multimedia1. Linear Multimedia

Display of electronic information used in this kind in a row, and without interference from the user interactively , and examples of the videos , and movies, and animation , it starts with the beginning of the presentation and ends at the end, without there being any input from the user.

2. Interactive Multimedia This allows the type of multimedia to control the

application, through the choice of subjects, and change the direction of travel, and change the output of the application based on user input , and depending on the needs of the show, through the use of tools different input, and also called a media non-linear, and from Examples: educational programs, and gaming software , and Internet sites , and encyclopedias. 

The elements necessary for the production of multimedia applications

First: the hardware (equipment) used in production:

1. Screen

2. Scanner

3. Microphone

4. Digital Camera

We need to produce a multimedia presentation to the elements and components together many involved in the production of the final application , the devices and equipment , and digital information and software used in the production process and supply

Second : The digital information:1. Photos and Graphics: may be fixed or mobile, an

d have multiple formats and extensions , vary in their clarity and size shelf and method of representation in the computer.

BitmapIs represented by a bitmap image using colored

dots "pixels“ , which is distributed on a network .

Transparency

Movement Size Quality Format

NO NO Few Good JPEG

YES YES Few Acceptable GIF

NO NO Large Very Good BMP

Vector images : In this system uses curves and colored areas in the

drawing of images, these spaces may be filled with colors, fixed (such as: red, green, etc.). Of the most popular vector graphics files with the extension SWF.

2. Digital Audio Audio files with the extension WAV: Automatic is

the formula that works within the Windows environment.

Audio files with the extension MPEG: This type is characterized by the possibility of reducing the file size without noticeable effect on quality.

Audio files with the extension MIDI: This type is used for the transfer of sounds from musical instruments to computer-mediated soundcard.

3. Digital VideoDigital film consists of the image, movement and sound,

similar to what we see in any scene in our daily lives, and take movies stored inside the computer in many forms, vary in quality and size of shelf, including:(AVI,WMV, MPEG)

Quality Size Format Type

High Quality

Large AVI Audio Video Interleave

High Large WMV Windows Media Video

Medium Few MPEG Moving Pictures Expert Group

3. TextsThe texts of the most important elements of

multimedia, it is the basis for the success of the message or idea of the desired application, better implementation convey the idea by using the least number of words, phrases, and simple language and understandable.

Third Production of  multimedia programs1. Processing programs and text editors (Microsoft Word)2. Word processing programs, and edit photos and graphics,

including: (Adobe Photoshop): and is the most popular software used in

editing and graphics and bitmap images, and create graphics for Web pages.

(Corel draw): a program to deal with vector graphics and production, and especially the work on the paintings of large-size ad .

3. Processing programs and movies, edit, and output: using these programs among the filmmakers and the Pravda propaganda.(Smoke),(Adobe Premiere),(Adobe After Effects)

4. Programs to process sounds and editing and production: special programs are logged and processed sounds, add effects and integrate them with each other . (Nuendo),(Orchestral),(Pro tools),(Cubase),(Reason)
