I have a single wave file, I drop it in to Sequence view and it show up as exactly two bars (in 4/4) or 8 beats - which is what I expected.
I look at the Soundfile information and it sees the tempo information as 102 BPM. The length is 4.70 seconds which is 8 beats at 102BPM.
I then drop the same file in to Clip view. I go to play the clip and it says it is 12 beats long. It plays the 8 beats and then 4 beats of silence.

What is going on?
