File Extension MP4 Information, tips and instructions |
||||||||||||||||||||||||||||||||||||||||
File Extension MP4This extension is used for files created using the MPEG-4 compression. This is under the MPEG-4 specification. MP4 files may contain both video and image files compatible on most players. This file extension can run on cross platforms including Mac, PC, and Linux. Because MP4 files may contain either audio or video files, Apple Corporation created M4A in compliance with the MP4 standard. This extension is designed to contain only audio files to distinguish it from the other MP4 files. It adapts the standards used in MPEG-1 and MPEG-2. An MPEG-4 file can have a different compression for audio and video files. Audio files are compressed similar to ACC compression. MPEG-4 compressions are commonly used in streaming video and audio files over the Internet. Some applications including Windows Media Player may require additional codec to be able to play an MP4 file. Portable devices such as Sony PSP and Apple iPod are capable of supporting MP4 files among other gadgets. On the other hand, conversion applications such as Magic Video Converter by MagisVideoSoft can convert audio and video files with different extensions to MP4 and vice versa. For playing MP4 files, applications such as Apple QuickTime Player, Roxio Toast, and several portable players can be used. Similar file extensions
