CreateHookKeyframesInterpolated - ComfyUI Built-in Node Documentation

Creates a sequence of hook keyframes with interpolated strength values between a start and end point. The node generates multiple keyframes that smoothly transition the strength parameter across a specified percentage range of the generation process, using various interpolation methods to control the transition curve.

`strength_end`	The ending strength value for the interpolation sequence (default: 1.0)	FLOAT	Yes	0.0 - 10.0
`interpolation`	The interpolation method used to transition between strength values (default: LINEAR)	COMBO	Yes	`LINEAR` `EASE_IN` `EASE_OUT` `EASE_IN_OUT` `EASE_OUT_IN` `SINE` `CUBIC` `QUARTIC` `QUINTIC` `EXPO` `CIRC` `BACK` `BOUNCE` `ELASTIC`
`start_percent`	The starting percentage position in the generation process (default: 0.0)	FLOAT	Yes	0.0 - 1.0
`end_percent`	The ending percentage position in the generation process (default: 1.0)	FLOAT	Yes	0.0 - 1.0
`keyframes_count`	The number of keyframes to generate in the interpolation sequence (default: 5)	INT	Yes	2 - 100
`print_keyframes`	Whether to print generated keyframe information to the log (default: False)	BOOLEAN	Yes	True/False
