Reconnecting and Recapturing Multiclips
When a media file for a multiclip angle is offline, Final Cut Pro indicates that the entire
multiclip is offline (a red slash appears through the icon). When you view a multiclip in
the Viewer, offline angles are indicated by a “Media Offline” frame.
Reconnecting media files for angles in a multiclip is the same as reconnecting media files
for other clips. When you reconnect media files to multiclip angles, you can reconnect
angles that are offline, online, or both.
When you batch capture a multiclip, Final Cut Pro captures the media files for all angles.
