The difference between mov and mp4: 1. The MOV format is a container of QuickTime, which not only includes video and audio, but also includes Java, scripts, Skin, pictures, etc. It is a very complex packaging format; 2. MP4 extracts and standardizes the audio and video parts of the MOV format, and can also install some simple scripts.
The difference between mov and mp4:
MOV format is a container of QuickTime, which not only includes video and audio, but also It can contain Java, scripts, Skin, pictures, etc. It is a very complex packaging format. (In the past, there was a movie-themed website specifically made with MOV on the Apple website, and you could also package games into MOV)
MP4 extracts and standardizes the audio and video parts of the MOV format, and can also install some simple ones. Scripts are far less complex than MOV.
It can be said that MP4 is just a standardized subset of MOV. IE M4V used to be Apple's MP4 format with DRM copyright protection, but later it became confusing and it was not so strictly called M4V.
Apple streamlined its MOV format and submitted it to the ISO standardization plan, and the MP4 format was born. Therefore, Apple is compatible with MOV and MP4, and it is originally owned by Apple.
mp4 does not explain the universal iso container that encapsulates the mpeg4 series encoding. m4v is a container developed by Apple. It can be understood that the apple version of mp4 is very close to mp4. The file structure is basically the same as mp4 and the suffixes can usually be changed to each other. The difference that does not cause problems is that m4v supports DRM protection and AC3 audio, while mp4 does not seem to support ac3 audio. DRM on m4v seems to be a bit special. The mov is obviously different from the above two.
Generally, mov files are generated by professional software The output encoder encoding supports many professional encodings outside the mpeg4 series, such as RGB, YUV, PNG/TIFF sequences, DV5P ProRes and other audios. It supports LPCM/ADPCM, ac3, DTS and other encodings that mp4 does not support. The file results of mov are also many different from mp4. mov is not an iso container. Some standards of mp4 are based on mov. The history of the container is earlier than mp4. It can be understood as the apple version of avi. As for why all three are decoded by quicktime, the reason is very simple. Some standards of mp4/m4v are based on mov. They all belong to quicktime files and can be observed in the import window of professional software. MP4 m4v mov are all in the quicktime files file category. In large video software, they generally require quicktime decoding
