Goals:
  1. Use dummy objects to animate the logo and camera
  2. Text on a path
  3. Control the visibility of objects
  4. Set up video post to output glow and lens flare effects
Key Points:
  1. Camera Rig
    1. Grouping and centering the logo
    2. Creating the dummy objects
      1. Inner for tilt - use local coordinates
      2. Outer for pan
    3. Linking - Camera to inner, inner to outer
    4. Animate - the benefits of using two dummies
    5. The curve editor
  2. Text on a path
    1. Creating the path and the text
    2. Apply the PathDeform modifier

      2. Path deform axis
      3. Rotation
      4. Percent
        1. Animate
        2. The curve editor
  3. Controlling Visibility with the curve editor
    1. Select object then add a visibility track
    2. Add keys, use zoom extents
    3. Edit the keys for visibility for values 0.0 to 1.0
    4. Edit the curve
  4. Animated lens flares
    1. Set up of the path
      1. Create the path from a segment of a spline. position in front slightly
      2. Create a point and attach to path using Pathdeform
      3. Animate and adjust the curves
    2. Set up Video Post
      1. Scene event
      2. Image filter event
      3. Image output event
    3. Edit the lens Flare
      1. Importance of saving *.lzf file
      2. Setting the node source
      3. Use update, VP que and preview
      4. Animate the size
        1. initial: 0, growth: 45, maintain: 45, drop off: 0
        2. Adjust the curves
      5. Lens flare settings
        1. Preferences- turning on and off
        2. Radial color
        3. Transparency
        4. Play, play, play and save, save, save
