What is MP4 ?
MP4 is the official multimedia container for MPEG-4 video and audio. Although such video can be stored in a number of modern containers, including MPEG-2 PS/TS and Matroska, the development of MP4 is important because it gives hobbyists a replacement for the outdated AVI container which became the standard for MPEG-4 ASP (DivX, XviD, 3IVX, etc,...) video.
What is SWF?
SWF, has variably stood for "Small Web Format" or "Shockwave Flash". It is a partially open repository for multimedia and vector graphics, originating with FutureWave Software and then coming under the control of Adobe. Intended to be small enough for publication on the web, SWF files can contain animations or applets of varying degrees of interactivity and function.
SWF currently update functions as the dominant format for displaying "animated" vector graphics on the Web. It may also be used for programs, commonly games, using ActionScript.
