I have 2 tracks of video (2 camera angles) I am trying to edit it using multcam wizard in excalubur.  I did some practice edits laying my markers and naming the tracks.  Ran multicam and it did the 14 edits.  So now I delete the markers and the master track and start over again putting in markers.  I control A to select all run excalibur with multcam and it gives me an error :object required.  How come it won't work with multicam now.  Need help.. just a rookie.
