The difference between video and video is different in definition, origin and characteristics.
First of all, explain the differences.
1, video: video is a machine or something that can display images to some extent.
2. Video: Video refers to various technologies that capture, record, process, store, transmit and reproduce a series of still images in the form of electrical signals.
Second, different origins.
1, video screen: The main technology of video screen originated from an organic compound with regular molecular arrangement between solid and liquid discovered by Austrian botanist Reinitzer in 1888.
2. Video: Video technology first developed from the emergence of cathode ray tube TV system, but later the invention of new display technology made the coverage of video technology wider.
Third, the characteristics are different.
1. video: video is a display tool that displays some electronic files on the screen through a specific transmission device and then reflects them to the human eye.
2. Video: Video can be recorded and transmitted through different physical media: when video is shot or transmitted by radio, it is an electrical signal, while when it is recorded on a magnetic tape, it is a magnetic signal; In fact, the video quality changes with the way of shooting and capturing and the way of storage.
1, different definitions
WMV: A technical standard for real-time multimedia transmission on the Internet independent of coding mode. Microsoft hopes to use it to replace technical standards such as QuickTime and file extensions such as WAV and AVI.
AVI: Audio and video interlaced AVI is a video format released by Microsoft and one of the oldest formats in the video field.
2. Different advantages
WMV: The main advantages are: extensible media types, local or network playback, extensible media types, streaming priority, multilingual support, scalability and so on.
AVI: the format is convenient to call, the image quality is good, and the compression standard can be selected at will. It is one of the most widely used and longest-lasting formats.
REALVIDEO: It can transmit uninterrupted video on the Internet with large bandwidth. In this respect, it is a strong competitor of ASF.
FLV: Because the file it forms is very small and the loading speed is very fast, it makes it possible to watch video files on the network. Its appearance effectively solves the shortcomings that the exported SWF file is huge after the video file is imported into Flash and cannot be used well on the network.
MP4: You can choose the appropriate MP4 parameters according to your mobile phone. Support batch conversion, and can handle multiple files. MP4 video clips are diverse. Fast conversion speed, friendly interface and extremely simple operation.
3. Different formats are classified
WMV: It belongs to network video, and it is a file compression format introduced by Microsoft. It adopts independent coding mode and can directly watch video programs on the Internet in real time.
AVI: It belongs to local video. Video and audio can be interwoven to play synchronously.
REALVIDEO: it belongs to network video, and can broadcast network audio or video resources live. RealMedia can set different compression ratios according to different network transmission rates, so as to realize real-time transmission and playback of image data on low-rate networks.
FLV: It belongs to FLV streaming media format and is a new video format.
MP4: It belongs to mobile phone video conversion. Mobile phone video format refers to the format of video content watched by mobile phone and stored in mobile phone memory or memory card. These formats are different from the video formats of network streaming media watched by mobile browsers. When converting mobile video, MP4 format is the best quality at present.
