I have a serious problem with the clone tool. I have a render from Cinema 4D (it's a fly through clouds). It has a flaw, there is on many frames a horizontal rift, which I have to clone away. The cloning works fine in the beginning, but now that I'm done I see that the cloning got sort of copied and spread onto subsequent frames, so the farther into the clip, the more destroyed the clip is. It is as if the clone tool was not affecting only the current frame, but it somehow affected all subsequent frames and destroyed everything.
Can someone help me with this clone tool behaviour? I need to start all over, but how to affect only the current frame?
