This makes MP4 a portable and web-friendly video format. Almost all of the original quality is retained. Reducing the file size doesn’t immediately impact the quality of the file, either. The high degree of compression used in MP4 videos makes the files much smaller than in other video formats. The standard specifies how the data is stored within the container itself but not how that data is encoded. MP4 is considered a digital multimedia container format-essentially a file containing a bunch of data that’s been compressed. The current version-MPEG-4 Part 14-was released in 2003. Initially created in 2001, MPEG-4 Part 12 was based on the QuickTime File Format (.MOV). Because of this, MP4 is an international standard for audio-visual coding. MP4 files were created under the ISO/IEC 14496-12:2001 standard by the ISO/IEC and Motion Picture Experts Group (MPEG).
