Adjusting the Speed or Velocity graph border


    When you drag an ease handle beyond the top or bottom of the graph area, After Effects calculates a new minimum or maximum value based on how far you dragged outside the graph, and it redraws the graph so that all the values you specified for that layer property are visible in the graph by default. You can manually adjust the size of the Speed or Velocity graph border when you want to make greater changes to the speed.

To adjust the Speed or Velocity graph border:

    Position the pointer tool on the graph border and, when the pointer becomes a double-arrow cursor, drag up or down.

    If you do not want the graph to be resized automatically when you drag a handle beyond the top or bottom of the graph area, deselect the icon (the Graphline icon) to the right of the property values. Deselecting this icon lets you zoom in on a portion of the graph resized beyond the graph area, but note that part of the graph may not be displayed.

To change the default graph area size:

  1. Choose Edit > Preferences > Display.
  2. For Default Height of Timeline Graphs, specify the number of cells (one cell equals 14 pixels).
