Characteristics and Uses

A MOV or Quicktime Movie file is a file format developed by Apple Inc, and used in its Quicktime app. It is a multimedia container, which can also work as a MPEG-4 video container. Compression is done with a proprietary algorithm developed by Apple.

A MOV file contains one or more tracks. Each track contains a specific type of data: audio, video, effect or text (for example: subtitles). Data in each tract can be in the form of a digitally-encoded media stream, or as a reference to a file containing the media stream. Tracks are structured with objects called Atoms, which are organized in a hierarchical manner. This capacity of containing data in an external file, makes MOV files suitable for editing, as it is not necessary to rewrite all the data.

This file format is object oriented, giving the format the capacity to expand using new object types. Objects are also easily parsed due to its hierarchical organization.

Atoms are the basic data unit of MOV files. They act as containers of information. Each atom has size and type fields. If it also has a version field and a flags field, it is called a full atom. An atom is identical to a box, as described in the ISO standard for MPEG-4 and Motion JPEG-2000. Each atom is identified by a 32-bit unsigned integer, usually interpreted as a four-character ASCII code.

Being organized in a hierarchical manner, an atom can contain other atoms, which in turn can also contain other atoms. This structure is described using the words parent, child, grandparent, etc.

Atoms can be of different types. For example, Movie Data atoms contain media data, Preview atoms contain information about the preview image. The preview image or poster is an image suitable for display. MOV files also contain metadata, which stores information on country, language, etc. Metadata is stored in the form of key-value pairs.

Brief History

The first release of the full Quicktime file format specification was on September 4, 2007. The Quicktime file format has been used as the basis of the MPEG-4 standard, and the JPEG-2000 standard, both developed by the International Standardization Organization (ISO).

Once downloaded, follow the steps below:

Step 1 – Click on the installer and follow the given steps. They are straightforward.

How to Use Image Files to Recover MOV Files

Image files are bit-by-bit copies of digital drives. They can be created using Disk Drill, by accessing the respective option from the “Extras” menu available next to each detected drive.  Image copies are useful for MOV file recovery and for backup purposes.

In the case of MOV recovery, working on image files is an advised practice, as it reduces the risk of damaging the original source. In addition, the process can be repeated on extra copies. For these reasons Digital Forensic practitioners usually work on image copies.

Image files can also be used for backups, with the added advantage of also storing deleted files not yet overwritten by the operating system. On the downside, a backup using an image copy may result in unnecessary used space, as the resulting size will be the same as the full size of the original source.
