Hi,
all you need to do is to reconnect the master-clips, then the subclips follow automatically…
When you open the project, a window appears telling you that media-files are offline. Select “reconnect”. Another window opens up listing all the offline files. Select “search” if the file- and reelnames are identical on both computers. Otherwise you need to connect your media manually with the “locate” function. (but again, you only need to do the masterclips, so it should not be too time-consuming)
