The differences between video and video are different definitions, different origins and different characteristics.
First, the interpretation is different
1, video screen: video screen is a machine or something that can display images in other degrees.
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, the origin is different
1, video screen: the main technology of video screen originated from 1888, an organic compound with regular molecular arrangement between solid and liquid, which was discovered by Austrian botanist Reinitzer.
2. Video: Video technology first developed from the creation of cathode-ray tube TV system, but the invention of new display technology later made the video technology cover a wider range.
Third, the characteristics are different
1, video screen: video screen is a display tool that displays certain electronic files on the screen through a specific transmission device and then reflects them to human eyes.
2. Video: Video can be recorded and transmitted through different physical media: when the video is shot or transmitted by radio, it is an electrical signal, while when it is recorded on magnetic tape, it is a magnetic signal; The video quality actually changes with the way of shooting and capturing and the way of storage.
1 has 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-Video Interlaced AVI, a video format released by Microsoft, is one of the oldest formats in the video field.
2. Different advantages
WMV: The main advantages are: scalable media types, local or network playback, scalable media types, stream prioritization, multilingual support, scalability, etc.
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 and has a large bandwidth. It is a strong competitor of ASF in this respect.
FLV: Because the file it forms is extremely small and the loading speed is extremely fast, it makes it possible to watch the video file on the network. Its appearance effectively solves the shortcomings that the exported SWF file is huge and cannot be used well on the network after the video file is imported into Flash.
MP4: You can choose the appropriate MP4 parameters according to your mobile phone. Support batch conversion, and can handle multiple files. MP4 video editing is diverse. And the conversion speed is fast, the interface is friendly, and the operation is extremely simple.
3. Different formats are classified
WMV: It belongs to network video, and it is a file compression format introduced by Microsoft, which adopts independent coding mode and can directly watch video programs on the Internet in real time.
AVI: It belongs to local video. It is possible to interweave video and audio for synchronous playback.
REALVIDEO: It belongs to network video, and can broadcast the 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.
