What frame rate to use when shooting videos
It depends on the shoot and the purpose of the shoot I can share my experience as I do video portfolios.
Depending on sound
If you're going to use a piece of background music then you don't need to worry about the framerate you can shoot in 24 frames for a cinematic cinematic look you can shoot in 60 frames and slow it down to 24 frames or 30 frames depending on the shot and depending on the way you wanted to look.
If there is a human wise in the world in the picture I would prefer to shoot in 24 frames per second as that is the standard and it gives you the Cinematic look after you colour grade it.
24 FPS
30 FPS
60 FPS
120 FPS
This gives you the freedom in the post-production to play either in 30 frames per second or 60 frames per second or 90 FPS as you decide and depending on the content or the way you want it to be played.
Remember most of the cameras do not record audio you in 120 frames per second so you need to add the audio in all the 120 FPS footage you shoot and please remember to speed the audio according to the playing speed of the the the footage.
There are new professional cameras from Sony, Panasonic and Canon which can shoot 240 frames per second, of course, it comes with an additional cost and memory consumption and more computing power in the post-production or editing table.
There are two disadvantages if you shoot in 4k
1. it takes more memory or space in the memory card when you shoot in 4K so you need 4K so you need need to plan accordingly for an extra memory card
2. In the post-production or in the Edit table do you need a powerful computer to edit the 4K footage you need a processor with at least 8 cores and 16 threads, I would recommend at least using Ryzen 7 2700.
I would advise you to have a shooting plan with the proper frames per second second second for every shot.
