ComfyUI Node: 🎨 MI2V Motion Painter

🎨 MI2V Motion Painter:

MotionPainter is a versatile node designed to facilitate the creation of motion effects in images by allowing you to draw arrows that describe the desired motion paths. This node is particularly beneficial for artists looking to add dynamic elements to their static images, providing an intuitive interface to specify motion vectors directly on the image canvas. The primary goal of MotionPainter is to enable you to visually communicate motion intentions, which are then processed to create animations or motion effects. By using simple drag-and-drop actions, you can place or remove arrows, making it easy to experiment with different motion paths and achieve the desired visual outcome. The node handles the image processing on the client side, ensuring a seamless and interactive experience.

🎨 MI2V Motion Painter Input Parameters:

image

The image parameter is a required input that represents the image you wish to apply motion effects to. This parameter accepts image data, which is processed and displayed on the canvas for you to draw motion arrows. The quality and resolution of the input image can significantly impact the final output, so it is advisable to use high-quality images for the best results.

arrows

The arrows parameter is a required input that takes a string representation of the motion vectors you wish to apply to the image. This parameter allows you to specify the direction and magnitude of motion through a series of coordinates. The input should be formatted as a multiline string, where each line represents a separate motion vector. Properly defining these vectors is crucial for achieving the desired motion effect.

unique_id

The unique_id is a hidden parameter that uniquely identifies each instance of the MotionPainter node. This parameter is used internally to manage the state and settings of the node, ensuring that each image and its associated motion vectors are processed correctly. You do not need to modify this parameter, as it is automatically handled by the system.

🎨 MI2V Motion Painter Output Parameters:

IMAGE

The IMAGE output parameter provides the processed image with the applied motion effects. This output is the result of the motion vectors being applied to the input image, creating a dynamic visual effect. The processed image can be used for further editing or as a final product, depending on your artistic goals.

STRING

The STRING output parameter returns the motion vectors in string format, reflecting any changes or adjustments made during the processing. This output is useful for reviewing or reusing the motion paths in future projects, allowing you to maintain consistency across different works.

🎨 MI2V Motion Painter Usage Tips:

• To achieve the best results, ensure that your input image is of high quality and resolution, as this will directly affect the clarity and effectiveness of the motion effects.
• Experiment with different arrow placements and directions to find the most visually appealing motion paths. Use the left drag to place arrows and right-click to remove them, allowing for easy adjustments.

🎨 MI2V Motion Painter Common Errors and Solutions:

🎨 MI2V Motion Painter_<unique_id>: Failed to get image!

• Explanation: This error occurs when the node fails to receive the processed image from the client side, possibly due to connectivity issues or incorrect image data.
• Solution: Ensure that your client-server connection is stable and that the input image data is correctly formatted. Try reloading the image and executing the node again.

🎨 MI2V Motion Painter_<unique_id>: Image received, canvas changed!

• Explanation: This message indicates that the image has been successfully received and the canvas has been updated with the new motion vectors.
• Solution: No action is needed as this is a confirmation message. You can proceed with further processing or adjustments as needed.
