Final Cut Pro: Avoid creating multiclips that contain both drop frame and non-drop frame clips

NTSC video is recorded with either drop frame or non-drop frame timecode. The differences between these two timecode methods are detailed in the Final Cut Pro User Manual (available under the Final Cut Pro Help menu). You should avoid making multiclips which contain both drop frame timecode clips and non-drop frame timecode clips. You may encounter unexpected results if you use multiclips which contain source clips of both timecode methods. While shooting, set all cameras and decks to record the same way — all using drop frame or all using non-drop frame. If you need to make multiclips from clips which were recorded using both drop frame and non-drop frame timecode, you should choose Modify > Timecode to change clips as necessary so that all the clips which constitute any given multiclip all use the same timecode method.
