User Manual Vol2 р 246
“When you create a multiclip, Final Cut Pro sorts the clips you selected by the values in
their Angle properties. If a clip’s Angle property is empty, Final Cut Pro looks at the clip
name, reel name, and finally the media filename to derive angle information. Final Cut Pro
assumes the first number in the reel name or filename is an angle number. ”
