File Extension MP4 H.264 File Type MPEG-4 Video File H.264 Encoded Video File Description MP4 is currently the most popular video format, commonly used for sharing video files on the Internet and can be played on most devices. The MPEG-4 video is compressed with MPEG-4 video encoding. Audio is compressed using AAC compression. Video file encoded with H.264 compression, which is a popular format for high definition video; often used as the video format for AVCHD camcorders, HDTV, Blu-ray, and HD DVD; generally refers to a video file that is actually an.MP4 file. Developed by Moving Picture Experts Group N/A Difference MP4 is a file container format, while H.264 is actually a video compression codec that requires a video container to host the encoded video. Most of the time, H.264 refers to MP4 file encoded with H.264 codec, and a file with the '.h264' extension is generally a misnamed.MP4 file (or another supporting container file format such as.AVI or.MKV).
The latest Socionext video-processing IC includes transcoder devices that convert between High-Definition (HD) and H.264 video data and MPEG-2 video data.

What is H.264? H.264 is an industry standard for video compression, the process of converting digital video into a format that takes up less capacity when it is stored or transmitted.
Video compression (or video coding) is an essential technology for applications such as digital television, DVD-Video, mobile TV, videoconferencing and internet video streaming. Standardising video compression makes it possible for products from diﬀerent manufacturers (e.g. Encoders, decoders and storage media) to inter-operate. An encoder converts video into a compressed format and a decoder converts compressed video back into an uncompressed format. Recommendation H.264: Advanced Video Coding is a document published by the international standards bodies ITU-T (International Telecommunication Union) and ISO/IEC (International Organisation for Standardisation / International Electrotechnical Commission). It defines a format or syntax for compressed video and a method for decoding this syntax to produce a displayable video sequence.
The standard document does not actually specify how to encode (compress) digital video – this is left to the manufacturer of a video encoder – but in practice the encoder is likely to mirror the steps of the decoding process.
