Working with clips shot in slow motion on a phone

[media kat]

I'm going to be working with a bunch of footage shot from different cameras, including phones in a 24fps sequence. Some of the clips will be shot at 60fps and 120fps while other clips will be shot and slowed down on the phone. I understand the concept of interpreting the clips that are shot at a HFR.

1. Do the clips that are shot and automatically put into slow motion need to have anything done to them in Premiere OR will they just play back in slow motion in my 24fps sequence?

Thanks.
