ComfyUI Node: SSsnap Apply Pose Diff ✂️

SSsnap Apply Pose Diff ✂️:

The ApplyPoseDiff node is designed to facilitate the application of pose differences to a sequence of frames, allowing for smooth transitions and adjustments in pose animations. This node is particularly useful in scenarios where you need to apply calculated pose differences to an original frame pose, taking into account previous frame data and optional scaling factors. By leveraging this node, you can achieve more natural and fluid pose transitions, which is essential in animation and motion capture applications. The node's primary goal is to ensure that pose adjustments are applied accurately and efficiently, enhancing the overall quality of the animation process.

SSsnap Apply Pose Diff ✂️ Input Parameters:

pose_diff

The pose_diff parameter represents the difference in pose keypoints between two frames. It is crucial for determining how much adjustment is needed to transition from one pose to another. This parameter is essential for the node's execution as it directly influences the resulting pose adjustments. There are no specific minimum or maximum values, but it should be a valid pose keypoint data structure.

original_frame_pose

The original_frame_pose parameter is the pose keypoints data of the current frame before any adjustments. It serves as the baseline for applying the pose differences. This parameter is vital as it provides the initial pose data that will be modified based on the pose_diff.

prev_original_frame_pose

The prev_original_frame_pose parameter contains the pose keypoints data of the previous frame. It is used to calculate the ratio of movement and ensure consistency in pose transitions. This parameter helps in maintaining smoothness across frames.

canvas_width

The canvas_width parameter specifies the width of the canvas on which the pose is applied. It is an integer value with a default of 1440. This parameter is important for scaling the pose data correctly to fit the canvas dimensions.

canvas_height

The canvas_height parameter specifies the height of the canvas on which the pose is applied. It is an integer value with a default of 1440. Similar to canvas_width, this parameter ensures that the pose data is scaled appropriately for the canvas.

neck, right_elbow, right_wrist, left_elbow, left_wrist, right_knee, right_ankle, left_knee, left_ankle

These parameters are boolean toggles that determine whether specific body parts should be adjusted based on the pose difference. By default, right_wrist and left_wrist are set to True, while others are False. These toggles allow for selective application of pose differences, providing flexibility in animation.

scaled_pose_diff

The scaled_pose_diff parameter is an optional pose keypoint data that represents additional scaling adjustments to be applied over time. It is used to create more gradual transitions in pose adjustments. This parameter is optional and can be omitted if not needed.

current_step

The current_step parameter is an optional integer that indicates the current step in a sequence of pose adjustments. It is used in conjunction with total_steps to calculate the progression of the pose transition. This parameter is optional and can be omitted if not needed.

total_steps

The total_steps parameter is an optional integer that defines the total number of steps in the pose transition sequence. It works with current_step to determine the interpolation factor for gradual pose adjustments. This parameter is optional and can be omitted if not needed.

SSsnap Apply Pose Diff ✂️ Output Parameters:

adjusted_frame_pose

The adjusted_frame_pose output parameter provides the pose keypoints data after applying the pose differences and any optional scaling adjustments. This output is crucial as it represents the final pose that can be used for rendering or further processing. The adjusted pose ensures that the animation transitions smoothly and accurately reflect the intended movements.

SSsnap Apply Pose Diff ✂️ Usage Tips:

• Ensure that the pose_diff and original_frame_pose data are correctly formatted and contain valid keypoints to avoid errors during processing.
• Utilize the boolean toggles to selectively apply pose differences to specific body parts, allowing for more controlled and targeted adjustments.
• When using scaled_pose_diff, current_step, and total_steps, ensure that these parameters are set appropriately to achieve smooth and gradual pose transitions over time.

SSsnap Apply Pose Diff ✂️ Common Errors and Solutions:

Pose size mismatch.

• Explanation: This error occurs when the shapes of the current, previous, or delta pose data do not match, indicating a discrepancy in the number of keypoints.
• Solution: Verify that all input pose data have the same number of keypoints and are correctly formatted before processing.

Pose shapes mismatch.

• Explanation: This error indicates that the shapes of the adjusted and scaled poses do not match, which is necessary for calculating the difference.
• Solution: Ensure that both the adjusted and scaled pose data have the same structure and number of keypoints.

Input pose data is invalid or malformed.

• Explanation: This error suggests that the input pose data is either empty or incorrectly structured, preventing successful extraction of keypoints.
• Solution: Check the input data for completeness and correct formatting, ensuring that it contains valid pose keypoints.
