What is a h264 file and how do I open a h264 file?

H264 is a video file encoded with H.264 compression, which is a popular format for high definition video. It is often used as the video format for AVCHD camcorders, HDTV, Blu-ray, and HD DVD, and generally refers to a video file that is actually an MP4 file. H264 is currently one of the most commonly used formats for the recording, compression, and distribution of video content. The final drafting work on the first version of the standard was completed in May 2003, and various extensions of its capabilities have been added in subsequent editions. The H.264 standard can be viewed as a group of standards. A specific decoder decodes at least one of the profiles. The decoder specification describes which profiles can be decoded. The H.264 name follows the ITU-T naming convention, where the standard is a member of the H.26x line of VCEG video coding standards; the MPEG-4 AVC name relates to the naming convention in ISO/IEC MPEG, where the standard is part 10 of ISO/IEC 14496, which is the suite of standards known as MPEG-4. H.264 is typically used for lossy compression which is purely from a mathematical stand point, although the amount of loss may sometimes be imperceptible. It is also possible to create truly lossless encodings using it H264.
