The document discusses cloning in Final Cut Pro X. It notes that cloning allows filming the same person in different areas of the shot to make it appear they are talking to themselves. This can be used to make band music videos look more professional. The key things to consider for cloning are keeping the camera still, properly timing the dialogue, matching eye lines, and keeping lighting consistent between shots. With practice, cloning can be done easily in Final Cut Pro X by placing multiple video clips on the timeline and cropping them together, then adding color matches and filters to make the edit look realistic.
