You can have the camera set with a high FPS.
The files need to be processed/rendered using applications like Adobe Premiere.

The simplest answer is that high frame rates allow for slowing footage down for slow motion effects. You need an editor that allows you to reduce the playback speed of your videos to obtain slow motion. You can also do this with the GoPro mobile app by selecting the speed option and choosing SLOW.
Now, to really go into detail and answer your question, a little history about movies and videos is required. Originally, movies were recorded in 16fps. These old black and white movies didn't have live sound recorded to them and instead had subtitle cards displayed and would have music played over the entirety of the film. Latter, an analog sound-on-disc system called Vitaphone was developed to allow for syncing of the actors voices to the movie. To be able to sync properly, the film had to be recorded in 24fps. As technology developed, the cinema standard became recording at 24fps and is still considered more, "Cinematic" looking to many people.
TV and video changed the standard to 30fps. This is because of the US power standard, which uses Alternating Current cycles as 60 sine waves per second. Because of this, TVs were designed for screen updating every 30 frames or two fields of 15 frames each second. To get the best video image, video created for TV traditionally is recorded at 30fps.
Now, with typical computer monitors having a refresh rate of 60Hz, and the latest gaming displays reaching all the way to 240Hz, higher frame rates can be used for even crisper and cleaner looking video. For this reason, many videos that are uploaded to online sources like YouTube use 60fps.
Taking the above into account, you need to decide what playback frame rate you want to use as your sequence setting in your editor. To achieve 50% slow motion playback, you need to double the frame rate setting you plan to use for your sequence. In other words, if you plan on making a 30fps video, then to be able to obtain 50% slow motion, you need to record in 60fps. If you want super slow motion at 25% playback speed, you need to record in 120fps.
In general, you'll want to select a sequence setting for playback speed somewhere in the 24fps-30fps range. If you need to know how slow you can safely reduce playback speed too by percentage, these are safe slow motion settings.
240fps slowed by 25% - 10%
120fps slowed by 50% - 20%
60fps slowed by 50% - 40%
48fps slowed by 62.5% - 50%

Bottom line is what and how you like it.
1. you need an editor goprostudio was the editor for slo mo using flux.. you can use powerdirector ditor and the speed. you can slow down to a speed that will not cause stuttering or frames. 25-50 is ideal for any fps. good luck. there is no long story to this but videos on youtube to watch.
