Frame rate:
It refers to the number of frames per second, usually in FPS, such as 25 FPS
The higher the frame rate, the more image frames per unit of time, and the smoother the video will be. Ordinary video files run between 25 and 30fps. Games are typically played at 60fps.
At the launch of the onePlus 7 in nineteen nineteen, the concept of 90Hz screen refresh rate was featured. A 90Hz refresh rate, which translates to 90 frames per second, also makes it smoother.
Bit rate
Bit rate and bit rate are the same concept. From a technical point of view, bit rate is more technical
The bit rate refers to the amount of data transmitted in a unit of time, usually in seconds. For example, 128 KBPS indicates that the amount of data transmitted over the network is 128 KB per second.
The higher the bit rate, the more data received per unit time over the network, the higher the broadband requirements, also means that the compression ratio at the coding side is relatively low.
