Why can't I render an iteration movie?

You cannot render an iteration movie if either of the following is true:

• The fractal is not 100% calculated.

• Iteration data is not available.

This can happen if you open a fractal from disk that was saved without iteration data (that is, the Save iteration data option in the Advanced Settings dialog box wasn't selected). This can also happen if you have just rendered a zoom movie, which may destroy the iteration data.

The most efficient way to recreate the iteration data is to zoom in, and then choose Undo from the Edit menu to force a total recalculation.
