Mp4 is the official file extension of the multimedia container format MPEG-4 part 14, which is the digital audio or digital video portion of MPEG-4. Because its file extension is .mp4, MPEG-4 Part 14 is often referred to simply as MP4. MP4s can actually contain multiple audio, video and subtitle streams as they are container formats and not simple file formats.

The Flash source file, which holds the timelines and multimedia elements, uses the .FLA (Flash Authoring) extension and is published to an .SWF file for playback by the Flash media player.Originally, SWF meant "ShockWave Flash," which was confusing because Shockwave is a different authoring package that uses the .DCR extension for playback files (see Shockwave).
