In fact, the number of frames is the abbreviation of the number of generated frames, which can be interpreted as the number of still pictures. That is to say, if the frame rate of an animation is constant at 60 frames per second (fps), then the frame number of one second is 60, and the frame number of two seconds is 120.
Due to oral habits, we usually confuse frame number and frame rate. Every frame is a still image, and the illusion of motion is formed by displaying frames quickly and continuously, so a higher frame rate can get smoother and more realistic animation.
Application of frame number
When you look at a static picture with the naked eye for more than 24 frames per second, it will be considered as a continuous dynamic video, so you can shoot 60 frames per second, and then adjust the number of frames per second to about 24 frames per second through software, then the image you shoot in one second can be played slowly for two seconds, and it will be continuous and will not get stuck.
If you can shoot 90 frames per second, you can slow down by at least one to three seconds in slow motion, and so on. High-speed video can capture many details and wonderful moments that we easily ignore. Playing video in slow motion will also make the video more interesting, which is why more and more manufacturers begin to pay attention to the function of high-speed video.
