I am working on an HDV project in FCP 7. I'm putting markers on master clips and then creating sub-clips, but there's one particular clip that is giving me trouble. I place markers on it, set the IN and Out around the markers, create the sub-clip, but the markers are not there. I've done a Save As..., trashed preferences and quite and opened the project back up, but to no avail. Does anybody know what might be wrong with this clip or if there are other troubleshooting actions I might try?
