HOW SLOW MOTION VIDEO WORKS & HOW TO SHOOT IT
Slow motion video offers the viewer a completely dynamic experience in the sense that visually, the storyteller can play around with the concept of time and add more emphasis on a particular moment which would otherwise be impossible in real life.
Shooting slow motion is relatively simple, but still requires some fundamental filming knowledge and post-production experience.
The first thing to look out for in terms of camera settings and functionality is the frame rate at which you are shooting. In most cases, filmmakers would prefer to shoot at either 24 or 25 frames per second (fps). Slowing down 25fps is not advised as the viewer would identify individual frames.
However, if your camera has the ability to shoot 60fps, you could then slow the footage down to 25fps thus giving the effect of slow motion.
The higher the frame rate at which you shoot, the slower the motion you can achieve. However, be aware that in most cases, the higher the frame rate the lower the resolution, depending on which camera model you are shooting with.
