ComfyUI Node: Keyframed Condition

Keyframed Condition:

The KfKeyframedCondition node is designed to attach a condition to a keyframe within your animation or visual project. This node allows you to specify a condition that will be evaluated at a particular time, enabling you to create dynamic and responsive animations. By using keyframes, you can interpolate between different states or values over time, providing smooth transitions and complex animations. This node is particularly useful for AI artists who want to add conditional logic to their animations, making them more interactive and engaging.

Keyframed Condition Input Parameters:

conditioning

This parameter accepts a conditioning input, which is a tuple containing a tensor and a dictionary. The tensor represents the condition's value, while the dictionary contains additional metadata or pooled outputs. This input is crucial for defining the initial state of the condition that will be attached to the keyframe.

time

This parameter specifies the time at which the condition should be evaluated. It is a floating-point value with a default of 0 and a step of 1. The time parameter allows you to place the keyframe at a specific point in your animation timeline, ensuring that the condition is applied precisely when needed.

interpolation_method

This parameter determines the method used to interpolate between keyframes. It accepts a list of available easing methods, with "linear" as the default option. The interpolation method defines how the transition between keyframes will occur, allowing you to create smooth or custom transitions based on your animation needs.

Keyframed Condition Output Parameters:

KEYFRAMED_CONDITION

This output parameter returns the keyframed condition, which includes the keyframe tensor and any associated metadata. The keyframed condition is essential for further processing or integration into your animation schedule, enabling you to create complex and dynamic animations.

Keyframed Condition Usage Tips:

• Use the time parameter to precisely control when the condition should be evaluated in your animation timeline.
• Experiment with different interpolation_method options to achieve the desired transition effects between keyframes.
• Combine multiple KfKeyframedCondition nodes to create intricate animations with various conditional logic.

Keyframed Condition Common Errors and Solutions:

"Invalid conditioning input"

• Explanation: This error occurs when the conditioning input is not in the expected format (a tuple containing a tensor and a dictionary).
• Solution: Ensure that the conditioning input is correctly formatted and contains both a tensor and a dictionary.

"Time value out of range"

• Explanation: This error occurs when the specified time value is outside the acceptable range for the animation timeline.
• Solution: Verify that the time value is within the valid range and adjust it accordingly.

"Unsupported interpolation method"

• Explanation: This error occurs when an invalid interpolation method is specified.
• Solution: Check the list of available interpolation methods and select a valid option.
