You can drop varied framerates into a timeline (sequence), but it becomes a compromise for all but the clips that match the sequence’s settings. That’s very important with FCP. FCP works best when the sequence settings (codec, size, framerate) match those of the clip. In fact, when you place the first clip into a sequence, FCP will ask if you want it to set the sequence to match the clip’s settings. FCP does not scale or change framerates well on-the-fly so the video will play roughly. The most recommended workflow is to convert all clips in an edit to a common codec like ProRes. Usually Compressor is used to do that. Then, you’ll have a smooth-running edit with minimal rendering needed.
