After Effects Interface Options
Switches:

Make Shy
      Click the little guy icon on the layers you want to hide
      Click the bigger little guy icon to hide all shy layers
Collapse Transformations
      For Illustrator files (vectors)
Quality
      Faster at low quality
Effects
      On or off
Frame Blending
      Used to speed up or slow down a video (must turn on the Frame blending icon above)
Motion Blur
      Used to blur between frames (must turn on the M icon above)

Compostion Window Features:
On bottom:
      Comp windows can be set smaller or larger
      See Safe Action and Credit Zones
      Change to New time
      Take Snapshot and Show snapshot
      Can check the R G B or alpha of a comp by clicking the RGBA buttons in the window
      Region of Interest
      Comp windows can be set to Full, Half, Third or Quarter Resolution
On Right side:
      Show Timeline
      Show Hierarchy (click + top open the nodes)
Layers
      Layer - New - Solid
            Apply an Effect - Try some of the Render effects:
            Audio Spectrum, Audio Waveform, Cell Pattern, Checkerboard, Grid, Lightning,
Radio Waves (Wave Motion & Stroke),
      Layer - New - Text
            Use the Character floating menu to change the parameters

Edit - Duplicate to make a copy of a layer (Will take the effects with it)
      
Can cut a footage item in two (or more)
            Move time slider to the correct spot
             Edit - Split Layer

To stretch a video (make it slower or faster):
            Select the layer and Layer menu - Time Stetch (adjust the %)
Keyframes
To Effect Keyframes
      Select the keyframes first
      Animation menu - Keyframe Assistant - Ease In, Ease Out
      Also try Time Reverse Keyframes

To do fine tune adjustments on the timing of the motion (interpolation):
Doubleclick on the name Position, Scale, Rotate, etc.
A set of curves will appear - move them slightly
Animation menu - Keyframe interpolation - select Bezier
Masking
      You can use the Pen tool (in the tool palette) to draw a mask
      Layer - Mask menu items (Mask Shape, Feather, Opacity, Reset, Remove)
Animating a Mask - Open the arrow under the layer and open the Mask arrow
      Set keys on shape, opacity, etc.
Making a Nested Comp (sometimes called a PreComp)
Uses:
      To allow you to put one effect or transform on lots of layers
      Can apply multiple transforms to the same image
      Can reuse the animation (and update it easily)
      Make it easier to work when you have lots of layers

Make an animation in a Comp using as many layers as seems appropriate
Composition Settings: Name the Comp
Composition Menu: New Composition
      Name it FullPiece

Notice the Tabs in the Comp window (you can jump between comps)

You can drag the original Comp icon from the Project window to the new comp or timeline

You can make as many comps as you like (it will speed up rendering time)

Tip: It starts by processing layers on the bottom and works its way up when rendering

PreComposing exisiting layers

Select Layers in the original comp
Layer - Pre-compose

Leave All Attributes - leaves the keyframes and effects in the original Comp
Move All Attributes into New Composition - used when you want to add a new effect or change the render order

Prerendering a Nested Comp

Will speed up the viewing and rendering of a complex nesting of Comps

Create a Comp
Render it using the settings specified in class
Import this new movie

To Render a final Movie

      Save the Project before making a movie
      Quit all other Applications

      Composition menu - Make Movie
      Name it - name.mov

Save it to the same place you saved your files (it will take up lots of space)
      Don't worry about the Save as Type box we will change this later

Click Current Settings (blue)
      Quality = Best
      Resolution = Full
      * Time Span - Length of Comp (make sure Composition Settings is correct)
      Frame Rate - 29.97
      
Click Output Module - Lossless (blue)
      Format - Quicktime Movie
      Video Output
            Compressor
                  Select Animation
            Make sure it is millions of colors OK

To make a small movie to bring over to Audition

      Save the Project before making a movie
      Quit all other Applications

      Composition menu - Make Movie
      Name it - name.mov

Save it to the same place you saved your files (it will take up lots of space)
      Don't worry about the Save as Type box we will change this later

Click Current Settings (blue)
      Quality = Best
      Resolution = Full
      * Time Span - Length of Comp (make sure Composition Settings is correct)
      Frame Rate - 30

Change the settings to Medium
Click Stretch
Set to 360 x 240
      
Click Output Module - Lossless (blue)
      Format - Quicktime Movie
      Video Output
            Compressor
                  Select Sorenson Video 3
            Make sure it is millions of colors OK
            Channels RGB (NO alpha)
            Depth (millions) OK
