About SWF

Originally limited to presenting vector-based objects and images in a simple sequential manner, the format in its later versions allows audio (since Flash 3), video (since Flash 6) and many different possible forms of interaction with the end-user. Once created, SWF files can be played by the Adobe Flash Player, working either as a browser plugin or as a standalone player. SWF files can also be encapsulated with the player, creating a self-running SWF movie called a "projector".
Adobe makes available plugins to play SWF files in web browsers on many desktop operating systems, including Microsoft Windows, Apple Mac OS X, and Linux on the x86 architecture. As of 2007 intensive development had taken place on Gnash, a free-software implementation of a SWF player. Another FOSS implementation is swfdec.
Based on an independent study conducted by Millward Brown, over 99% of Web users now have an SWF plugin installed, with around 90% having the latest version of the Flash Player.[citation needed]
Sony PlayStation Portable consoles can play limited SWF files in Sony's web browser, beginning with firmware version 2.71. Both the Nintendo Wii  and the Sony PS3  consoles can run SWF files through their Internet browsers.
Also many mobile phones support flash as standard, such as Nokia.(From Wikipedia)

About AVI

AVI is a derivative of the Resource Interchange File Format (RIFF), which divides a file's data into blocks, or "chunks." Each "chunk" is identified by a FourCC tag. An AVI file takes the form of a single chunk in a RIFF formatted file, which is then subdivided into two mandatory "chunks" and one optional "chunk".
The first sub-chunk is identified by the "hdrl" tag. This sub-chunk is the file header and contains metadata about the video, such as its width, height and frame rate. The second sub-chunk is identified by the "movi" tag. This chunk contains the actual audio/visual data that make up the AVI movie. The third optional sub-chunk is identified by the "idx1" tag which indexes the offsets of the data chunks within the file.
By way of the RIFF format, the audio/visual data contained in the "movi" chunk can be encoded or decoded by software called a codec, which is an abbreviation for (en)coder/decoder. Upon creation of the file, the codec translates between raw data and the (compressed) data format used inside the chunk. An AVI file may carry audio/visual data inside the chunks in virtually any compression scheme, including Full Frame (Uncompressed), Intel Real Time (Indeo), Cinepak, Motion JPEG, Editable MPEG, VDOWave, ClearVideo / RealVideo, QPEG, and MPEG-4 Video.(From Wikipedia)
