Flash - Motion Tweening

Flash - Motion Tweening

• Creating a movie frame by frame would be very
  time consuming
• It would also be very jerky unless you were to
  draw each frame of the bouncing ball in a
  slightly different position sort of like going
  from top to bottom in baby steps.
• Flash will do this for you automatically
• First lets start a new file and draw a blue ball
  just like we did last lesson

  frame choose a frame on the timeline further down
  the line say frame 10.
• Right click and choose Insert Keyframe
