Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.
Refers to recording, manipulating, and displaying moving images, especially in a format that can be presented on a television.
Video was first developed for mechanical television systems, which were quickly replaced by cathode ray tube (CRT) systems which were later replaced by flat panel displays of several types.
There are two types of video which are digital and anolog video.
FPS: Frames per second
Digital video is recorded digitally, as ones and zeros. Since it is stored in a digital format, digital video can be recognized and edited by a computer, which is also a digital device.
Video production is the process of producing video content. It is the equivalent of filmmaking, but with images recorded digitally instead of on film stock. There are three stages of video production: pre-production, production, and post-production. Pre-production involves all of the planning aspects of the video production process before filming begins. This includes scriptwriting, scheduling, logistics, and other administrative duties.
Video compression is the process of encoding a video file in such a way that it consumes less space than the original file and is easier to transmit over the network/Internet.
It is a type of compression technique that reduces the size of video file formats by eliminating redundant and non-functional data from the original video file.
Once a video is compressed, its original format is changed into a different format (depending on the codec used). The video player must support that video format or be integrated with the compressing codec to play the video file.
