Flash video format has two extensions available: .flv and .swf. How are they different?
(1) A .flv file (flash video) is a video stream and audio based on picture. If you are running a streaming service, flv would be a good choice. The upstream condition is that any part of this file can be accessed by the client terminal and is not waiting to be downloaded at any time. Then again, running a streaming service is expensive.
(2).swf is also the Macromedia Flash file format, which is a complete video-audio file and has scripts and more. This will facilitate HTTP (progressive) downloads, also known as "psuedo streaming". When part of the file is downloaded, the video clip plays immediately, but the client will wait for the flash file fragment to download before accessing it (no fast forwarding) unless the entire file is downloaded in its entirety. This is what we often talk about, it is a simple, inexpensive, and convenient way to stream your video media. SWF is not the official abbreviation. Some people have claimed that it is the abbreviation of "ShockWave Flash" or "Small Web Format".
