Answers.Text: @MikeA.Christensen there is two different frame rates described as 24 fps.  There is 24fps and 23.976fps (otherwise known as 24fps drop frame)  This is an artifact of how color information was encoded in the space that used to be taken up by a frame of video back in the day and still hangs around now.  24fps is an odd one since it wasn't a broadcast spec prior to digital, but it still has a drop frame specification in addition to the non-drop frame that actually has exactly 24 frames per second.
