What is the difference between mp4 format and mov format?

MOV format

QuickTime movie format is an audio and video file format developed by Apple, which is used to store common digital media types. It can also be said that MOV is a brand-new encoded video format released by Apple. The Quicktime software of Apple system can play MOV format. In addition, both Apple's iPhone and iPad support their own MOV format. With such an excellent video format, many players have begun to support playback, such as storm video, QQ video and popular software.

MP4 format

The MP4 format is a format for mobile terminal equipment. MP4 format is mainly used in various mobile platforms, such as Samsung mobile phone, iPhone, iPad and some DVD devices, which all support MP4 video playback.

2. The file size and image quality are different.

Avi, mp4 and rmvb are much smaller than mov files, and the compression ratio of the former formats is much larger than the latter. Although the storage space is relatively small, it will affect the image quality, which is not conducive to post-editing production, especially post-special effects and color matching. This is very similar to the RAW format and jpeg format of digital cameras. The former is lossless compression format and the latter is lossy compression format, and the former has more room for later adjustment. This is why many experienced photographers prefer to shoot with the former. The bit rate of many broadcast digital cameras is around 24M, and the digital SLR (Quan Huafu) is also around 80~90M. The professional digital cameras used by TV stations to shoot TV dramas all reach about 500M per second.

MOV is a common streaming video format, even better than WMV and RM in some aspects, and can be supported by many multimedia editing and video processing software. Saving movies in MOV format is a very good choice.

MOV format files are organized in the form of tracks. A MOV file structure can contain many tracks. The limit of the number of tracks has some empirical values, which will change because of the increasing ability of the computer. However, the MOV format file itself has no predefined limit on the number of tracks.
