What is SWF


What is SWF

SWF (originally an abbreviation for "ShockWave Flash" this was changed to the backronym "small web format" to eliminate confusion with Shockwave, from which it was derived from) is a file format for multimedia, vector graphics and ActionScript in the Adobe Flash environment. Originating with FutureWave Software, then transferred to Macromedia, and then coming under the control of Adobe, SWF files can contain animations or applets of varying degrees of interactivity and function.

Currently, SWF functions as the dominant format for displaying "animated" vector graphics on the Web. It may also be used for programs, commonly browser games, using ActionScript.

SWF files can be generated from within several Adobe products: Flash, Flash Builder (an IDE), as well as through MXMLC, a command line application compiler which is part of the freely available Flex SDK. Other than Adobe products, SWFs can be built with open source Motion-Twin ActionScript 2 Compiler (MTASC), the open source Ming library, the free software suite SWFTools, the proprietary SWiSH Max2. There are also various third party programs that can produce files in this format, such as Multimedia Fusion 2, Captivate, or SWiSH Max.

Main Features of SWF

As we all know that, SWF is a popular video format, so it surely has a lot of advantages, here we will discuss some main advantages of this popular video format below:

Early SWF format was praised because it created compact animations that were fast loading. Now, SWF files can incorporate sound and video and even bitmap files. A major advantage of SWF format is that it is vector based. This means that the graphics can be scaled easily, so they can be zoomed in or be fit onto different size screens, and the file will still look very clear and play very smooth (unlike bitmap animation). Other advantages of SWF format includes fast loading, easy and smooth compression (like PNG format), and it also supports transparencies (like PNG and GIF).

With all the formats though comes their disadvantage. There are not many with SWF but a major one is compatibility. One can not play a video in SWF format unless it has Macromedia Flash installed on the computer.
