ComfyUI Node: VizMotionBrush

VizMotionBrush:

The VizMotionBrush node is designed to visualize motion brush data, which is typically used in the context of optical flow and motion analysis. This node takes motion brush data, which represents the motion between frames in a sequence, and converts it into a visual format that can be easily interpreted. The primary benefit of this node is that it allows you to see the motion patterns and flow within your data, making it easier to analyze and understand the dynamics of the motion. By transforming the motion brush data into an image format, you can leverage visual inspection to identify patterns, anomalies, or specific areas of interest in your motion data.

VizMotionBrush Input Parameters:

motion_brush

The motion_brush parameter is the core input for this node. It represents the motion brush data, which is a tensor containing the motion information between frames. This data is typically generated by an optical flow model and is used to visualize the motion patterns. The motion_brush parameter must be of the type MotionBrush, which ensures that the data is in the correct format for processing. This parameter is crucial as it directly impacts the visualization output, providing the necessary data to generate the visual representation of the motion.

VizMotionBrush Output Parameters:

IMAGE

The IMAGE output parameter is the result of the visualization process. It represents the visualized motion brush data in an image format. This output allows you to see the motion patterns and flow within your data, making it easier to analyze and understand the dynamics of the motion. The IMAGE output is a tensor that can be further processed or displayed using image visualization tools, providing a clear and interpretable representation of the motion data.

VizMotionBrush Usage Tips:

• Ensure that the motion_brush input is correctly formatted and represents valid motion data to achieve accurate visualizations.
• Use the visualized output to identify patterns, anomalies, or specific areas of interest in your motion data, which can be useful for further analysis or processing.

VizMotionBrush Common Errors and Solutions:

Invalid motion_brush input

• Explanation: This error occurs when the motion_brush input is not in the correct format or does not contain valid motion data.
• Solution: Verify that the motion_brush input is of the type MotionBrush and contains valid motion data. Ensure that the data is correctly generated and formatted before passing it to the node.

RuntimeError: shape mismatch

• Explanation: This error occurs when there is a mismatch in the expected shape of the motion_brush data during the visualization process.
• Solution: Check the dimensions of the motion_brush input to ensure they match the expected format. The data should be a tensor with the appropriate dimensions for processing. Adjust the input data if necessary to match the expected shape.
