# Recursive Ops

Use Recursive Ops to perform a wide range of recursive, animation-based blending effects. Recursive Ops uses the processed result of the previous frame and blends it with the current frame using a selected blending mode. It features a built-in colour selection, which constrains the accumulation effect within that selection. Additionally, it accepts an external matte input which also conditions the way in which the internal blending occurs.

To access the Recursive Ops menu, use:

- Timeline, then use ConnectFX (See Creating ConnectFX).

- Tools, then select from the menu.

This node accepts front and matte clips, and outputs a result and outmatte.
