Maya - pendulum

 There was a file for me to download and open up the scene in maya. 

 I then had to adjust the frame rate to 48, and at frame 1 and 48 I rotated the top sphere to -80 and at frame 24 rotated it to positive 80. 

 At first it swung too fast but this was because the frame rate wasn't set to 24 frames per seconds.

 I then had to batch render the files so I would have jpeg files to put into a sequence in after effects later.
