What is MOV file?

MOV is a popular video file format developed by the Apple company in 1998, used be default by the QuickTime player. A MOV file contains a single or multiple paths, and each of those paths is assigned with a specific type of data: video, audio or text (written). These paths may be also utilised to indicate the data within a different file. Each path usually uses one or more codecs, therefore an application utilising MOV files must support all the used codecs.

Advantages of MOV format

MOV is a popular format which is compatible with MAC, Windows iOS and Android systems. The MOV format is also greatly adjusted for video edition, because of the fact that specific fragments of data can be modified separately. Due to multiple data storing paths, it is possible to edit sound and image separately

Similarities between MOV and MP4

The MP4 format was developed on the basis of MOV – only minor changes were implemented. Both formats use in compression the MPEG-4 codecs and it is a lossy compression method therefore one should take into account loss of quality, however, this results in small size of files. Due to many similarities, MOV and MP4 files can be easily converted both ways, especially considering Apple systems; in other systems, certain complications may occur. Although the MOV format is relatively popular, the MP4 is currently more frequently encountered.
