It's not good to convert frame rate to a lower one, for example 30fps to 24fps, because you may lose motion information contained on these frame rates you throw away, which will result in video stuttering/jerky playback. We always use frame rate converter to change the lower frame rate to the higher one. If you have to reduce frame rate, make sure that you convert A to B, and A can evenly divide by B, for example, convert 60fps to 30fps, 120fps to 60fps, to avoid jerk/messed video audio or other problems with output videos.
