MPEG was developed in 1993 as MPEG-1 and it was a very popular format for audio and video storage. Today it is the most compatible media format in the world. When the format first appeared, it was innovate and ahead of its time, provided relatively high quality files while reducing their size and made it easy to upload and download files by compressing them. These features allowed creating video CDs, digital TV and digital audio broadcasting. Due to its age, MPG is no longer covered by any patents, that is why both Mac and Windows applications along with many hardware support MPEG video and audio natively.

F4V is a Flash Video format supported by Adobe Flash Player software and all browsers with flash video playback. The container uses boxes for data storage and it is compatible with h.264 video and AAC audio compression standards. F4V files provide better quality than FLV but need a newer version of Flash (9.0.115 or higher) and a faster processor.
