ComfyUI Node: AnimateDiff Keyframe 🎭🅐🅓

AnimateDiff Keyframe 🎭🅐🅓:

The ADE_AnimateDiffKeyframe node is designed to facilitate the creation and management of keyframes within the AnimateDiff framework. This node allows you to define specific points in your animation where certain parameters, such as scale, effects, and camera controls, can be adjusted to achieve desired visual outcomes. By leveraging keyframes, you can create smooth transitions and dynamic changes in your animations, enhancing the overall visual appeal and storytelling. The node is particularly useful for AI artists looking to add intricate details and control to their animations without delving into complex coding. It ensures that the specified parameters are applied at the right moments during the animation, providing a high level of precision and customization.

AnimateDiff Keyframe 🎭🅐🅓 Input Parameters:

start_percent

This parameter defines the starting point of the keyframe as a percentage of the total animation duration. It determines when the keyframe's effects will begin to take place. The value ranges from 0.0 to 1.0, with a default of 0.0, allowing you to specify the exact moment in the animation timeline for the keyframe to activate.

prev_ad_keyframes

This optional parameter allows you to input a group of previously defined keyframes. It helps in maintaining continuity and ensuring that the new keyframe integrates seamlessly with the existing ones. If not provided, a new keyframe group will be created.

scale_multival

This optional parameter allows you to specify a scaling factor for the animation. It can be a single float value or a tensor, providing flexibility in how the scaling is applied. This parameter is useful for creating zoom-in or zoom-out effects at specific points in the animation.

effect_multival

This optional parameter lets you define additional effects to be applied at the keyframe. Similar to scale_multival, it can be a float or a tensor, enabling a wide range of visual effects to enhance the animation.

cameractrl_multival

This optional parameter is used to control camera movements or adjustments at the keyframe. It can be a float or a tensor, allowing for precise camera control to create dynamic and engaging animations.

pia_input

This optional parameter allows you to input specific PIA (Pose Interpolation Algorithm) settings for the keyframe. It provides advanced control over pose transitions, making it easier to achieve smooth and natural movements in the animation.

inherit_missing

This boolean parameter determines whether the keyframe should inherit missing parameters from previous keyframes. The default value is True, ensuring that the keyframe maintains continuity with the preceding ones unless explicitly overridden.

guarantee_steps

This integer parameter specifies the number of steps for which the keyframe's effects are guaranteed to be applied. It ensures that the keyframe's impact is sustained for a certain duration, with a default value of 1 and a minimum value of 0.

AnimateDiff Keyframe 🎭🅐🅓 Output Parameters:

AD_KEYFRAMES

The output of this node is a group of keyframes (AD_KEYFRAMES) that includes the newly added keyframe. This output can be used in subsequent nodes to apply the defined keyframes to the animation, ensuring that the specified parameters are executed at the right moments.

AnimateDiff Keyframe 🎭🅐🅓 Usage Tips:

• To create smooth transitions, carefully plan the start_percent values of your keyframes to ensure they are evenly distributed across the animation timeline.
• Utilize the scale_multival and effect_multival parameters to add dynamic visual effects at specific points, enhancing the overall impact of your animation.
• Use the cameractrl_multival parameter to introduce camera movements, making your animations more engaging and visually appealing.
• Leverage the inherit_missing parameter to maintain continuity between keyframes, ensuring a seamless flow in your animation.

AnimateDiff Keyframe 🎭🅐🅓 Common Errors and Solutions:

"IndexError: list index out of range"

• Explanation: This error occurs when trying to access a keyframe index that does not exist in the keyframe group.
• Solution: Ensure that the index you are trying to access is within the range of the existing keyframes. Use the has_index method to check if the index is valid before accessing it.

"TypeError: unsupported operand type(s) for +: 'NoneType' and 'float'"

• Explanation: This error occurs when a parameter expected to be a float or tensor is None.
• Solution: Ensure that all required parameters are provided and are of the correct type. Check for any None values and replace them with appropriate float or tensor values.

"ValueError: start_percent must be between 0.0 and 1.0"

• Explanation: This error occurs when the start_percent value is outside the valid range.
• Solution: Ensure that the start_percent value is within the range of 0.0 to 1.0. Adjust the value accordingly to fit within this range.
