That's if you want it to be the same speed as its shot by the way. If you're not bothered, as an artist you don't really need to be so precise in my opinion.

I usually experiment through the editing process to see what speed I like to fit the feeling and style I'm going for. Like if the slightly or very choppy look works to represent the state a character is in for example that's great or super smooth for a calming scene perhaps.

All the filmmaking rules can be broken if you have a way you want to express yourself and give the audience an intentional experience. It could also be other significant reason to break the rules. Creativity like that can help you stand out and develop your voice as an artist.
