Characteristics and Uses

The MP4 file format is a digital multimedia container that can be used to store video, audio, subtitles, still images and other data, such as 3D graphs, menus and user interactivity. Usually, when used to store only audio, the file extension is changed to M4A.

MP4 is an abbreviation for MPEG-4 Part 14, also known as MPEG-4 AVC, where AVC stands for Advanced Video Coding, and MPEG refers to Motion Picture Expert Group. The MPEG is responsible for defining the digital audio and video industry standards.

MP4 is a reliable tool, highly compressed, which requires a low amount of bandwidth. It is based on the ISO/IEC 14496-12:2004 standard, which in turn is based on the QuickTime file format. Its structure is almost identical to the QuickTime file format, but with some added features. 

Brief History

Developed by the International Organization for Standardization, the MP4 file format history is basically defined by its two versions.

The MP4 file format version 1 was released in 2001 under the ISO/IEC 14496-1:2001 standard. Version 2 appeared in 2003 under the ISO/IEC 14496-14:2003. According to the ISO document of 2003, these versions are identified as mp41 and mp42 respectively.

As the MP4 is a container of audio and video data, it can also be used to contain only audio data. Thus, it is sometimes confused with the MPA file format, which also contains only audio data. Usually, players that can open MP4 files, can also open MPA files.

How to Use Image Files to Recover MP4 Files

Image files are a bit-by-bit copy of an original digital source. Thus, they contain all data available on the device, including deleted files still not overwritten by the operative system. On the downside, their size is the same as the one of the original source, and they may contain empty space.

Image files are a great tool for MP4 file recovery, as they can be used with Disk Drill, leaving the original source untouched.
