The H.264/264 video format was developed to provide good quality video at a lower bitrate level. The format has a large range of applications that attempt to cover video solutions from Internet streaming applications through to HDTV broadcasting with near lossless coding.
H.264/264 contains a number of features that allow it to compress video more effectively than previously. The main advantage of H.264 is the compression rate which is about twice as effective as MPEG-4. The image quality is a lot better and as such playback is more fluent, added to this the lower bit rate for network transmission means that it is widely adopted.

MP4 files (MPEG-4 Part 14) are multimedia files. MP4 is a container format that can store video, audio and subtitle data (as well as more depending on content). Since stores like iTunes uses this container format, and it is used with iPod and PlayStation Portable (PSP), MP4 files have become more common.
MPEG-4 Part 14 or MP4, formally ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital video and digital audio streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. A separate hint track is used to include streaming information in the file. The only official filename extension for MPEG-4 Part 14 files is .mp4.
