Okay! So my pendulum got smacked by someone which is why it’s so exaggerated within it’s movements.
My first video is of just the key frames
My second video is the smooth version
My third video is me moving scale keys and rotate keys to try and fix it, on Graph Editor.
My fourth video is me doing more messing around.
This is what my graph editor looks like;
This is the top base of the pendulum
This is the middle
This is the bottom.
