# Recursive Ops

Use Recursive Ops to perform a wide range of recursive, animation-based blending effects.

You can access the Recursive Ops Effect in the following ways:

- As a Batch node.
- From the EditDesk. Select Flame FX2 from the A/V Tools box and then click Recursive Ops.

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 will constrain the accumulation effect within that selection. Additionally, it accepts an external matte input which will also condition the way in which the internal blending occurs.

Repeat Mode Settings

Repeat Mode options box
  Select an option to fill the empty portions of the frame.

Range Settings

Range from field
  This field displays the beginning of the range of frames that will be impacted by the accumulation effect.
Range to field
  This field displays the beginning and end of the range of frames that will be impacted by the accumulation effect.
Range before button
  Select between bypass and cycle. Bypass eliminates the recursive ops effect. Cycle repeats the accumulation effect. This is applied before the set frame range.
Range after button
  Select between bypass and cycle. Bypass eliminates the accumulation effect. Cycle repeats the recursive ops effect. Applied after the set frame range.
