What are video bitrate and video resolution?

Video bitrate refers to streaming speed and file size. It measures the speed of transfer over the internet and how much bandwidth it will consume. Essentially, its the amount of data (bits) required to encode each second of video. The higher the bitrate, the larger the file.

The measurement also tells the encoder (a device that compresses video) what level of compression to use. But bitrate by itself doesnt determine video quality. This depends on factors such as resolution, frame-rate, and display size.

Video resolution measures the width and height of a video in pixels. A higher concentration of pixels leads to better visual quality. But a video with high resolution also needs a higher bitrate, otherwise, it wont look good on screen.

Thats why bitrate and resolution are intertwined, with different combinations yielding different video quality. For example, if your network speed is slow, it wont be able to handle a very high bitrate, and the video will look choppy. With video recognition technology increasingly used in the Internet of Things, video quality is also important for IoT application development.
