CreateHookKeyframesInterpolated - ComfyUI Built-in Node Documentation

This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! Edit on GitHub

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.

Inputs

Parameter	Data Type	Required	Range	Description
`strength_start`	FLOAT	Yes	0.0 - 10.0	The starting strength value for the interpolation sequence (default: 1.0)
`strength_end`	FLOAT	Yes	0.0 - 10.0	The ending strength value for the interpolation sequence (default: 1.0)
`interpolation`	COMBO	Yes	Multiple options available	The interpolation method used to transition between strength values
`start_percent`	FLOAT	Yes	0.0 - 1.0	The starting percentage position in the generation process (default: 0.0)
`end_percent`	FLOAT	Yes	0.0 - 1.0	The ending percentage position in the generation process (default: 1.0)
`keyframes_count`	INT	Yes	2 - 100	The number of keyframes to generate in the interpolation sequence (default: 5)
`print_keyframes`	BOOLEAN	Yes	True/False	Whether to print generated keyframe information to the log (default: False)
`prev_hook_kf`	HOOK_KEYFRAMES	No	-	Optional previous hook keyframes group to append to

Outputs
