How high of a frame rate do you need to shoot the bullets? Take the most common bullet, at the speed of sound 340m/s, the shooting range is about 1 meter, it takes 0.0029 seconds for the bullet to complete this 1 meter, if you can shoot 1000 pictures per second, then you can shoot 2.9 pictures of the bullet, that is to say, if the frame rate is below 1000FPS, it is basically useless to shoot the bullet, you can't even find the ghost shadow of the bullet.
But with AI, maybe you'll be able to shoot cool slow-motion videos, too.
Recently, NVIDIA (the one that sells graphics cards) showed the public an amazing AI they developed with MIT and Aalto University in Finland, an AI that can take low frame rate video and turn it into high frame rate video out of thin air.
The following motion picture was taken with a 30FPS camera, and after slowing down 8x, it looks like this.
