It is to put the encoded and packaged video and audio together according to certain specifications.
Video commonly used package formats
MOV
MOV is the QuickTime encapsulation format (also called movie format), which is an audio and video file encapsulation developed by Apple to store common digital media types. When QuickTime (*.mov) is selected as "Save as type", the movie will be saved as a mov file.
Quick Time movie format is an audio and video file format developed by Apple, so it is more suitable for the use and playback of Apple systems, and it is the most stable editing format in Final Cut Pro X.
Due to its technical characteristics of cross-platform and small storage space requirements, QuickTime uses MOV format files with lossy compression, and the picture effect is slightly better than that of AVI format.
MP4
is the most common international format. It can be used and played in common playback software. It occupies a small disk space and has clear picture quality. It is more stable to use MP4 format for editing in PR.
The WMV
Microsoft video format occupies a small disk space and is usually smaller than the MP4 format, but it is not recommended because less software is used for playback, and now the media industry rarely uses this format to edit or deliver films.
The abbreviation of FLV
FLASH VIDEO because it forms a very small file, the loading speed is extremely fast, making it possible to watch video files on the Internet, so generally the videos watched on the Internet are in FLV format.
Common Audio Package Formats
WAVE
, commonly known as WAV, is a sound file format developed by Microsoft. It is relatively stable in editing equipment, and its footprint and quality are larger than MP3.
MP3
is a commonly used format for downloading songs. The quality is not as good as WAV, but it occupies a small space and is convenient for downloading.
APEAPE
is one of the popular digital music lossless compression formats. This type of lossless compression format reduces the volume with a more refined recording method. After restoration, the data source files are the same, thus ensuring the integrity of the files.
