Keyframe problem

hello there!

I want to copy pencil lines into another key frame, to make it look more natural, but if i change them, they will be changed in any other keyframe too
What can i do that if i paste a keyframe into another and change them in the new one without touching all the others?

If I understood correctly your problem, what you need is to duplicate your drawing, from the Timeline or from the X-Sheet.

i want to copy a single frame into another and then change the positions to not make it look edgy, like i dont want to redraw it every single frame, but if i do that and change some vectors in the pasted frame the vectors and points also change in the frame and all the other frames which i dont want cuz i only have a picture then instead of a movement
sorry about my crap english and thanks for the reply already
