ComfyUI Node: Apply AnimateDiff-PIA Model 🎭🅐🅓②

Apply AnimateDiff-PIA Model 🎭🅐🅓②:

The ADE_ApplyAnimateDiffModelWithPIA node is designed to integrate PIA (Perceptual Image Animation) models into the AnimateDiff framework, enabling advanced motion effects and animations in your AI-generated art. This node ensures that the motion model being applied is compatible with the PIA format, and it handles the necessary preprocessing steps to prepare the model for animation. By leveraging the PIA model, you can achieve more nuanced and perceptually accurate animations, enhancing the visual quality and realism of your creations. This node is particularly useful for artists looking to add sophisticated motion dynamics to their AI-generated images, making the animation process more intuitive and effective.

Apply AnimateDiff-PIA Model 🎭🅐🅓② Input Parameters:

model_name

This parameter specifies the name of the motion model you wish to apply. It is crucial to select a model that is compatible with the PIA format to ensure proper functionality. The available options are determined by the get_available_motion_models function, which lists all the motion models that can be used with this node.

motion_model

This parameter represents the motion model object that will be used for animation. It must be of the type MotionModelPatcher and should contain the necessary PIA components, such as conv_in. This ensures that the model can be properly integrated and utilized within the AnimateDiff framework.

image

This parameter is a tensor representing the image to which the motion model will be applied. The image serves as the base for the animation, and the PIA model will use it to generate the animated output.

vae

This parameter is an instance of the VAE (Variational Autoencoder) used for encoding and decoding the image. The VAE helps in processing the image data, making it suitable for animation by the PIA model.

start_percent

This parameter defines the starting point of the animation as a percentage of the total animation duration. It allows you to control when the animation should begin, providing flexibility in timing. The value ranges from 0.0 to 1.0, with a default of 0.0.

end_percent

This parameter defines the ending point of the animation as a percentage of the total animation duration. It allows you to control when the animation should end, providing flexibility in timing. The value ranges from 0.0 to 1.0, with a default of 1.0.

pia_input

This optional parameter represents the PIA input settings. If not provided, a default InputPIA_Multival with a value of 1.0 will be used. This input helps in fine-tuning the PIA model's behavior during the animation process.

motion_lora

This optional parameter is a list of motion LoRA (Low-Rank Adaptation) settings that can be applied to the motion model. It allows for additional customization and refinement of the animation effects.

ad_keyframes

This optional parameter is a group of AnimateDiff keyframes that define specific points in the animation timeline. These keyframes help in creating more complex and dynamic animations by specifying changes at different points in time.

scale_multival

This optional parameter allows you to apply a scaling factor to the animation. It helps in adjusting the intensity of the motion effects, providing more control over the final output.

effect_multival

This optional parameter allows you to apply an effect multiplier to the animation. It helps in adjusting the strength of the animation effects, providing more control over the final output.

ref_multival

This optional parameter allows you to apply a reference multiplier to the animation. It helps in adjusting the reference values used by the PIA model, providing more control over the final output.

prev_m_models

This optional parameter represents the previously applied motion models. It helps in maintaining continuity and consistency when applying multiple motion models sequentially.

Apply AnimateDiff-PIA Model 🎭🅐🅓② Output Parameters:

MOTION_MODEL

This output parameter represents the motion model that has been applied and processed with the PIA settings. It is ready to be used for generating the animated output, ensuring that all necessary adjustments and integrations have been made.

Apply AnimateDiff-PIA Model 🎭🅐🅓② Usage Tips:

• Ensure that the selected motion model is compatible with the PIA format to avoid errors and ensure proper functionality.
• Use the start_percent and end_percent parameters to control the timing of your animation, allowing for more precise and tailored effects.
• Experiment with the scale_multival and effect_multival parameters to fine-tune the intensity and strength of your animations, achieving the desired visual impact.

Apply AnimateDiff-PIA Model 🎭🅐🅓② Common Errors and Solutions:

Motion model 'X' is not a PIA model; cannot be used with Apply AnimateDiff-PIA Model node.

• Explanation: The selected motion model is not compatible with the PIA format.
• Solution: Ensure that you select a motion model that is specifically designed for PIA. Check the available models using the get_available_motion_models function.

Passed-in motion model was expected to be PIA (contain conv_in), but did not.

• Explanation: The motion model does not contain the necessary PIA components, such as conv_in.
• Solution: Verify that the motion model includes the required PIA components. If not, select a different model that meets the requirements.

ValueError: Expected input tensor to have 4 dimensions, but got X dimensions instead.

• Explanation: The input image tensor does not have the correct dimensions.
• Solution: Ensure that the input image tensor is properly formatted with 4 dimensions (batch size, channels, height, width).

TypeError: 'NoneType' object is not iterable

• Explanation: One of the optional parameters, such as motion_lora or ad_keyframes, is not properly initialized.
• Solution: Check that all optional parameters are correctly initialized and not set to None if they are expected to be iterable.
