I'm trying out video editing for the first time and basicly I just want to cut a part of my video.
So I take Razor tool and click on these two blue lines I've drawn with MS Paint:
And now my clip is ruined. When playing or going frame by frame it jumps back and forth.
Like here: See that casting bar in video preview? It should be shrinking, but I go few frames ahead and it grows, because video gets back in time:
How did I manage to screw up so easily? How to correctly cut that part so I could move it/delete it without screwing up whole clip?
