Frame rate 、 Bit rate 、 The resolution of the 、 Definition concept

Frame rate ： Affect the fluency of the picture , It's proportional to the smoothness of the picture , The higher the frame rate , The smoother the picture , The lower the frame rate , The more dynamic the picture is .
1 The number of frames of pictures transmitted in seconds , It can also be understood that the graphics processor can refresh several times per second .

Bit rate ： Also called bit rate ： The video bit rate refers to the video to be played , The number of bits of the video file to be read per second (bit) Count .
Unit is bps(Bit Per Second), Higher bit rate , The more data is read per second , The better the picture quality under the same conditions （ Distortion ）.
The bit rate affects the volume , The higher the bit rate , The larger the volume is. , The smaller the bit rate , The smaller the volume .

The resolution of the ： Affect image size , It's proportional to the size of the image , The higher the resolution , The bigger the image , Lower resolution , The smaller the image .

clarity ： When the bit rate is certain , Resolution is inversely proportional to definition .
With a certain resolution , The bit rate is proportional to the definition .
