The clock reference is the timecode of the video, or the time address information. The positional reference is how fast it’s going. For example, at 3:21 into a music lyric video, the song is probably fading out and really slow. However, at that same point in an action movie, we may be seeing a fast forward to a more important date.

However, do not take my word for it. I have never studied the Pro Tools post-production system that this particular question is asking about. I did some video work with the Adobe suite, but only a tad bit of work at the tail end of a class. I am in no way an expert on this topic, so do your research.
