There is a way, right?
I have found out, that allmost all of my clips have those little triangles at the end - that is suppose to mean, "last frame". But those are no subclips! How could that happen? I looked in an earlier version - their the clips a just the way they are suppose to be (no triangles; audiotrans crossfades in the middle, when the two clips lie head-to-head.)
PS: As I think of it, the version without the triangles was the first cut. I took the project along and worked on it on my Labtop. Then I came back to the office and reconnected the project to the (original) Clips. Does the clips lose their Masterclip-status when you reconnect them?
Sorry, for the monologue, but I now understand what has happended:
PPr has extracted all the audiotracks from the video, they are all wavs now! No wonder, that there is now space for a crossfade.
But: how could that have happened?
PS: audiotracks ar all green, not blue anymore.
