On animate CC, when you make a new frame, the last frames drawing stays, is there a way to make that not a thing that's not erasing it everytime?
Use F7 (Blank Keyframe). This will create a new keyframe and remove any axisting assets from the previous frame.
F5: Insert Frames
F6: Inster Keyframe (creates a new keyframe containing contents of previous frame)
F7 (as stated above)
F8: Convert to Symbol
Those are the most uses keyboard shortcuts for years using this application.
