# Turning a Keyframe into a Breakdown

Katana supports a special kind of keyframe known as a breakdown. Breakdowns help you describe the motion between two keyframes by providing an intermediate value. Breakdowns maintain the same relative time with the keyframes either side, this helps maintain timing. For instance, with keyframes on frames 0 and 60 and a breakdown on frame 20, moving the keyframe on frame 60 to frame 30 would automatically move the breakdown to frame 10, thereby maintaining the 1:2 ratio of frames before and after. If a breakdown falls at the beginning or end of a curve, then moving the keyframe next to it moves the breakdown.

When the keyframe on frame 60 is moved to frame 30, the breakdown on frame 20 automatically moves to frame 10.

To convert a keyframe into a breakdown:

| 1. | Select the keyframe(s) to convert.

| 2. | Right-click and select Keyframe > Breakdown.

Tip: To change a breakdown back to a keyframe, repeat the steps above.

Note: Breakdowns are only different to keyframes while within the Curve Editor. Elsewhere, such as within the Dope Sheet, breakdowns are treated as normal keyframes.
