When used in video or audio, as in video editing, it indicates how much data is represented per unit of time, and “bits per second (bps)” is generally used.
\nA bit is the smallest unit of data that a computer handles.
\nTwo states of “0” and “1” can be expressed by 1 bit. (1 binary digit)
\nSimilarly, a byte representing the size of a file is a unit of data handled by a computer. (1 byte = 8 bits)
\nHere are some things to keep in mind about bit rates.
\nIn home appliance hard disk recorders, it is sometimes expressed as a recording mode such as XP, SP, LP.
\nThe higher the bit rate value (numerical value), the better the picture and sound quality, but the greater the amount of data (file size).
\nThe unit of bit rate is usually Mbps, which means 10 6 (10 to the sixth power) for video, and kbps, which means 10 3 (10 to the third power) for audio.
\nWhen burning a video to DVD, there is a limit to the amount of data that can be burned to DVD, and if you try to burn a long video, you will have to lower the bit rate, resulting in poor image quality. . To record high-quality video, the bit rate must be increased, which increases the amount of data required and shortens the recording time.
\nEven if the bit rate used is the same, the image quality and sound quality will differ depending on the encoder and compression method used for digitizing.<\/p>\n","protected":false},"excerpt":{"rendered":"
