What is the code rate? Part 2
Generally speaking, there are only a few common frame numbers that we use to make videos: 24 frames, 25 frames, 29.97 frames, and 30 frames.
Different areas and different uses require different frames.
Frames per second
Frame rate is also known as the abbreviation FPS (Frames PerSecond): frames per second. It refers to the number of image frames that are updated per second, which can also be understood as the graphics processor can update multiple times per second. The more frames per second (FPS), the smoother the motion is displayed. When capturing dynamic video content, the higher the number, the better.
If the frame rate exceeds the refresh rate of the screen, it only wastes graphics processing power, because the monitor cannot refresh as fast, so the frame rate that exceeds the refresh rate is wasted.
For games, in general, first person shooters pay more attention to the FPS level, if FPS is <30, the game will seem inconsistent. So, there is an interesting saying: “FPS (referring to FPS games) focuses on FPS (referring to frame rate).
The frame rate is not as high as possible. Most common mobile phone recording frame rates on the market are 30fps, TV 25/30 (common use) 50/60fps, etc. (sports shots), high-speed cameras 120/240 fps (slow motion)

Resolution
Resolution, also known as resolution and resolution, can be classified into two directions: screen resolution and image resolution.
Screen resolution (screen resolution) is the accuracy of the screen image and refers to how many pixels a monitor can display.
