Yes.
I have found the problem (I am an idiot, really…)
The sequence-settings are wrong. I think I have selected a wrong settings preset…
So I’ve created a new sequence with 1080p and it works! The rendering is quite fast (it doesn’t takes up so much time).
My only big problem is that I have to copy all cut-settings into the second sequence, if this is not possible I have to cut the complete clip again…
So is it possible to transfer the “cuts” to another sequence? Or even to change the sequence-settings?
Thanks,
Martin
