Generally, Bitrate measures down the data that is to be transmitted a single point of time. It’s the de-facto standard for measuring bits per second (bps), kilobits per second (Kbps or the megabits per second (Mbps). This defines the rate at which data is passed through the communication network. It can also be referred to as data rate.
Part 1. All About Video Bitrate and Audio Bitrate
What is Video Bitrate?
The term Video Bitrate is referred to the speed at which video is transmitted a given point of time. The more the speed, larger chunk of data is transferred at the given point of time. However, the consideration of correct bit rate depends on which device the videos are being played. In typical cases, an approx. value of 2mbps is deemed to be a good quality of video on web whereas a standard definition of DVD has 6 mbps.
What is Audio Bitrate?
On the other hand, Audio bitrate is termed as the number of bits used in playback time per unit that shows audio after source coding. They are defined as the compression rate used in encoding files in audio aspect. More the bitrate, better the quality of the sound!
Is a Higher or Lower Bitrate Better?
It goes without saying, to fetch a great quality of video, the higher bitrate is recommended. Putting differently, setting the video output in a higher bitrate will provide higher image quality as compared to lower bitrate.
