What file format is described as being determined by the Moving Picture Experts Group?

The file format determined by the Moving Picture Experts Group is MPEG, which stands for Motion Picture Experts Group. This group is responsible for developing standards for audio and video compression and transmission. The MPEG format includes a set of standards that enable the encoding, decoding, and transmission of multimedia files, which have become highly popular for their efficiency in compressing video and audio data while maintaining quality.

MPEG has evolved through various iterations, such as MPEG-1, MPEG-2, and MPEG-4, each improving upon the last in terms of compression and quality. This adaptability has made MPEG a foundational format in the digital media landscape, particularly for video streaming and storage.

The other formats mentioned are either specific to certain applications or developed by different entities. For instance, .AVI is a format developed by Microsoft and is known for its flexibility, while .WMV is also a Microsoft format designed specifically for streaming media. .MOV is a format developed by Apple for QuickTime.
