I have not selected scene detection anywhere. I thought that would only kick in if the camera was paused during recording, otherwise I would get a continous clip. That was what happened with my HDV camera. When recording a football match it spit the clips into the first and second half.
Come to think of it, scene detection might be selected in the importer which I am not using to load these clips. Wouold that make a difference? Yes, by loading I mean bringing them into Pinnacle.
