Animation is a method in which images are shown as a video at high speed. Today, most animations are made with computer-generated imagery (CGI). In traditional animation, to show on film, images are drawn or painted by hand on transparent celluloid sheets.
Animation: Animation is the process of displaying multiple images one after the other.
Information is represented as a sequence of zeroes and ones.ĥ. Digital video is audio/visual data in a binary format. (b) Digital Videos: Digital video is an electronic representation of moving visual images (video) in the form of encoded digital data. The red, green and blue intensities are used to record these videos. Analog video, represents moving visual images (video) in the form of analog signals. (a) Analog Videos: Analog video is created in a video camera. The most commonly used software for watching videos are: Quick Time, Real Player, window media player. It is used in multimedia to present more information and saves a lot of time. This is the best way to communicate with each other. Video: Video means moving pictures with sound. Commonly used software for playing audio files is: Quick Time. A special format is used for digital audio. The sound quality of these files is better than MIDI files. These files are larger in size than MIDI. Digital sound files are created from predefined music to record live music. (b) Digital Audio: Digital audio is a better alternative to MIDI files. It’s a flexible and easy way to create music projects in multimedia. It is a communication tool developed for computers and electronic devices. (a) MIDI: The full name of MIDI is Musical Instrument Digital Identifier. Audio is an important part of multimedia because the concept that we cannot understand in the form of text, we explain in audio format. Audio: In multimedia audio means recording or playing sound, speeches, music etc. Vector imagery requires less memory to store and thus we can use less data to represent the image. These images remain smooth even when zoomed in. (b) Vector Images: Vector images are drawn using lines, circles and other mathematical equations. Bitmap images require a large amount of memory. Generally bitmap images are not editable. A bitmap is a simple matrix of small dots called a pixel that creates a raster or bitmap image. (a) Raster or Bitmap Images: Bitmap images are real images that are captured from digital cameras or scanners. Sometimes we do not like to read the large amount of text therefore images are used to explain the concept in very easy manner. In multimedia we make the concept more effective and presentable with the help of images. Images: Every multimedia presentation is based on images. By clicking on this text we can easily and quickly go to the linked page.Ģ. These texts are displayed on the screen with blue underline. (b) Hypertext: Hypertext is text that contains links to other texts. (а) Static Text: Static text is a simple text that we use to type messages or other documents or given along with images to describe the image. We can use two types of text in multimedia. The most commonly used software for viewing text files are Microsoft Word, Notepad, WordPad etc. In multimedia we can present text in a very attractive way using fonts, colors and styles. It is a combination of characters and certain symbols.
Text: Text is the primary part of multimedia and the most common way of conveying information to another person. Email, newspaper, messaging, radio, TV context, etc. Multi means many and media means the way by which data can be transmitted or sent. Multimedia is a computer based technology where all kinds of information can be digitally presented, displayed, processed and transmitted.Īs the name suggests, multimedia is a combination of multi and media. Multimedia is a form of communication that combines different types of data such as text, audio, images, animations or video into a single presentation. Some of the areas where multimedia is widely used are education, training, reference materials, business presentations, advertising and documentation. It provides communication between users and digital information. Multimedia is an interactive media and provides many powerful ways to present information to the user.
