Though it is usually easy to work with, sometimes it may face issues like damage and corruption, due to which files of this format may not play appropriately, or MOV files may play only audio but not video. With MOV files, existing media can be embedded to media in another file. Summary: MOV is a popular video file format supported by various media players. MPV and MP4 files use the same MPEG-4 file container, and they usually use QuickTime as the standard with the most support. MOV files can contain multiple tracks, each track containing objects in a hierarchy called “atoms.” Atoms can contain media or edit data, or they can be parents to other atoms, however, they can only do one of the two actions. The International Organization for Standardization approved MOV files are the basis for the MPEG-4 Part 14 file.

fyi: I have visited OnePlus store as well and they confirmed its an issue. Sony PSP and DVD players are capable of viewing MOV video files based on the compatible software. the same file can be played via MX player or vlc so surely they arent bad files.

MOV files and QuickTime are often used in the editing of music and video (or the two combined).

Video editing software often use this file type. They can hold videos, video effects, text, images, subtitles, and audio. qt, is an extension of a QuickTime File Format (QTFF). Each file container is capable of holding multiple media types. This file extension is compatible with both Windows and Mac platforms. The MOV file extension is used to save video files with a proprietary compression algorithm designed by Apple.
