ComfyUI Node: Latent Keyframe 🛂🅐🅒🅝

Latent Keyframe 🛂🅐🅒🅝:

The LatentKeyframe node is designed to manage and manipulate keyframes within a latent space, which is particularly useful in advanced control scenarios for AI-generated art. This node allows you to create, modify, and interpolate keyframes, enabling smooth transitions and precise control over the latent variables that influence the generated output. By leveraging keyframes, you can achieve more dynamic and controlled results in your AI art projects, making it easier to fine-tune and experiment with different latent configurations. The primary goal of this node is to provide a flexible and powerful tool for managing latent keyframes, enhancing your ability to create complex and visually appealing AI-generated art.

Latent Keyframe 🛂🅐🅒🅝 Input Parameters:

batch_index

The batch_index parameter specifies the index of the batch to which the keyframe belongs. This integer value helps in organizing and managing keyframes within different batches, ensuring that each keyframe is correctly associated with its respective batch. The default value is 0, with a minimum value of BIGMIN and a maximum value of BIGMAX, allowing for a wide range of batch indices.

strength

The strength parameter determines the influence or weight of the keyframe within the latent space. This floating-point value controls how strongly the keyframe affects the generated output, with higher values indicating a greater influence. The default value is 1.0, with a minimum value of 0.0 and a maximum value of 10.0, providing flexibility in adjusting the keyframe's impact.

prev_latent_kf

The prev_latent_kf parameter allows you to pass in a previous LatentKeyframeGroup object. This optional parameter is useful for building upon existing keyframes, enabling you to add new keyframes to an already established group. If not provided, a new LatentKeyframeGroup will be created.

Latent Keyframe 🛂🅐🅒🅝 Output Parameters:

LATENT_KF

The LATENT_KF output parameter returns a LatentKeyframeGroup object. This object contains the updated set of keyframes, including any new keyframes added during the node's execution. The LatentKeyframeGroup is essential for managing and accessing the collection of keyframes, allowing you to further manipulate or utilize them in subsequent nodes or processes.

Latent Keyframe 🛂🅐🅒🅝 Usage Tips:

• To achieve smooth transitions between different latent states, carefully adjust the strength parameter for each keyframe, ensuring gradual changes in influence.
• Utilize the prev_latent_kf parameter to build upon existing keyframes, allowing for more complex and layered control over the latent space.
• Experiment with different batch_index values to organize and manage keyframes within different batches, making it easier to handle multiple sets of keyframes in your projects.

Latent Keyframe 🛂🅐🅒🅝 Common Errors and Solutions:

Expected strengths to be an iterable input, but was <type>

• Explanation: This error occurs when the strength parameter is not provided as an iterable (e.g., list or tuple) when expected.
• Solution: Ensure that the strength parameter is passed as an iterable if multiple strengths are required. For a single strength value, pass it as a float or integer.

index '<raw_index>' must be an integer.

• Explanation: This error occurs when the batch_index parameter is not a valid integer.
• Solution: Verify that the batch_index parameter is an integer and within the acceptable range defined by BIGMIN and BIGMAX.

No batched float_strengths passed into Latent Keyframe Batch Group node; will not create any new keyframes.

• Explanation: This warning indicates that no batched strengths were provided, and therefore, no new keyframes will be created.
• Solution: Ensure that the strength parameter is provided as a batched input if you intend to create multiple keyframes. If only a single keyframe is needed, this warning can be safely ignored.
