Using the Parameter Graph with paths

---

In Director, you can draw a path (i.e. a curve) to set the values of certain columns and/or column groups - such as a camera's E/W and N/S moves. For such columns, the parameter graph shows the distance along the path for each keyframe.

• When the path is first created, a distance of zero represents the first knot created, and distance increases in the order that knots were added to the path.

• Later editing of the path can change this; for example, the first knot may be deleted or moved.

If you edit the path, the parameter graph is automatically updated to reflect any changes in the distances.

Using the Parameter Graph with ratios

In Director, you can also set keyframe and inbetween changes in part or all of one column to be calculated as a ratio of the changes in another column. The values in one column are derived directly from those in another column. (See Using ratios).

For those parts of a column that are ratioed, you cannot edit their values in the Parameter Graph. This means that any ratioed sections of a column do not appear in the graph, and you cannot move the keyframe at the start of the ratioed section.
