LoRA Hook Keyframes Interpolation šŸŽ­šŸ…šŸ…“ Description

Generate smooth keyframe transitions for LoRA hooks in Animate Diff framework using various interpolation methods for dynamic animations.

LoRA Hook Keyframes Interpolation šŸŽ­šŸ…šŸ…“:

The ADE_LoraHookKeyframeInterpolation node is designed to facilitate the creation of interpolated keyframes for LoRA (Low-Rank Adaptation) hooks within the Animate Diff framework. This node allows you to generate a series of keyframes that smoothly transition between specified strength values over a defined percentage range. By leveraging different interpolation methods, you can create nuanced and dynamic animations that enhance the visual quality of your AI-generated art. The primary goal of this node is to provide a flexible and efficient way to schedule LoRA hooks, ensuring that the transitions between keyframes are smooth and visually appealing.

LoRA Hook Keyframes Interpolation šŸŽ­šŸ…šŸ…“ Input Parameters:

start_percent

This parameter defines the starting point of the interpolation range as a percentage of the total animation duration. It determines where the first keyframe will be placed. The value ranges from 0.0 to 1.0, with a default of 0.0. Adjusting this value allows you to control the initial position of the keyframe sequence within the animation timeline.

end_percent

This parameter specifies the ending point of the interpolation range as a percentage of the total animation duration. It determines where the last keyframe will be placed. The value ranges from 0.0 to 1.0, with a default of 1.0. This setting allows you to define the endpoint of the keyframe sequence, ensuring that the interpolation covers the desired portion of the animation.

strength_start

This parameter sets the initial strength value for the first keyframe in the interpolation sequence. The value ranges from 0.0 to 10.0, with a default of 1.0. This value determines the intensity of the LoRA hook at the start of the interpolation, allowing you to control the initial impact of the effect.

strength_end

This parameter defines the final strength value for the last keyframe in the interpolation sequence. The value ranges from 0.0 to 10.0, with a default of 1.0. This setting allows you to control the intensity of the LoRA hook at the end of the interpolation, ensuring a smooth transition to the desired final effect.

interpolation

This parameter specifies the method used to interpolate between the start and end strength values. It allows you to choose from various interpolation methods, such as linear or other predefined methods. This setting determines how the strength values will transition between keyframes, affecting the smoothness and style of the animation.

intervals

This parameter sets the number of intervals or keyframes to be generated between the start and end percentages. The value ranges from 2 to 100, with a default of 5. Increasing the number of intervals results in more keyframes and a smoother transition, while fewer intervals create a more abrupt change.

This boolean parameter, when set to True, enables the printing of keyframe information to the logger. The default value is False. Enabling this option can be useful for debugging and verifying the generated keyframes, providing insights into the interpolation process.

prev_hook_kf

This optional parameter allows you to provide a previous set of LoRA hook keyframes to which the new keyframes will be added. If not provided, a new LoraHookKeyframeGroup will be created. This setting enables the continuation or modification of an existing keyframe sequence, offering flexibility in keyframe management.

LoRA Hook Keyframes Interpolation šŸŽ­šŸ…šŸ…“ Output Parameters:

HOOK_KF

The output parameter HOOK_KF represents the generated or updated set of LoRA hook keyframes. This output is a LoraHookKeyframeGroup object that contains the interpolated keyframes based on the input parameters. It is used to apply the scheduled LoRA hooks to the animation, ensuring smooth transitions and dynamic effects.

LoRA Hook Keyframes Interpolation šŸŽ­šŸ…šŸ…“ Usage Tips:

  • To create a smooth transition between keyframes, increase the number of intervals. This will generate more keyframes and result in a more gradual change in strength values.
  • Experiment with different interpolation methods to achieve various visual effects. Linear interpolation provides a straightforward transition, while other methods can create more complex and interesting animations.
  • Use the print_keyframes option to debug and verify the generated keyframes. This can help you understand how the interpolation is being applied and make necessary adjustments.

LoRA Hook Keyframes Interpolation šŸŽ­šŸ…šŸ…“ Common Errors and Solutions:

strengths_float must be either an iterable input or a float

  • Explanation: This error occurs when the strengths_float parameter is not provided as a float or an iterable (e.g., list or tuple).
  • Solution: Ensure that the strengths_float parameter is either a single float value or an iterable containing multiple float values.

Invalid interpolation method

  • Explanation: This error occurs when an unsupported interpolation method is specified.
  • Solution: Verify that the interpolation method provided is one of the supported methods. Refer to the documentation for a list of valid interpolation methods.

start_percent and end_percent must be between 0.0 and 1.0

  • Explanation: This error occurs when the start_percent or end_percent values are outside the valid range of 0.0 to 1.0.
  • Solution: Adjust the start_percent and end_percent values to be within the range of 0.0 to 1.0.
