ComfyUI Node: ImageMotionGuider

ImageMotionGuider:

The ImageMotionGuider is a powerful node designed to create dynamic animations by guiding the motion of images across a specified range. This node is particularly useful for AI artists looking to add movement and depth to their static images, transforming them into engaging visual stories. By manipulating parameters such as movement range, frame count, and zoom level, the ImageMotionGuider allows you to simulate panning and zooming effects, creating a sense of motion and perspective. The node works by calculating the necessary steps to move an image horizontally across a canvas, optionally applying a zoom effect to enhance the animation. This capability is ideal for generating smooth transitions and animations in digital art projects, making it an essential tool for artists seeking to bring their creations to life.

ImageMotionGuider Input Parameters:

image

The image parameter is the input image that you want to animate. It serves as the base for the motion guidance process, and the node will apply the specified transformations to this image to create the animation sequence. This parameter is required and should be provided in an appropriate image format.

move_range_x

The move_range_x parameter defines the horizontal range of motion for the image. It determines how far the image will move along the x-axis during the animation. The value can range from -150 to 150, with a default of 0. A positive value moves the image to the right, while a negative value moves it to the left. This parameter is crucial for setting the extent of the image's horizontal movement.

frame_num

The frame_num parameter specifies the number of frames in the animation sequence. It controls the smoothness and duration of the animation, with more frames resulting in a smoother transition. The value can range from 2 to 150, with a default of 10. This parameter is important for defining the animation's temporal resolution.

zoom

The zoom parameter allows you to apply a zoom effect to the image during the animation. It specifies the maximum zoom level, with a range from 0.0 to 0.5 and a default of 0.0. A higher value results in a more pronounced zoom effect, creating a sense of depth and focus in the animation. This parameter is optional but can significantly enhance the visual impact of the animation.

ImageMotionGuider Output Parameters:

IMAGE

The IMAGE output parameter is the result of the motion guidance process. It is a sequence of images that represent the animated transformation of the input image. Each frame in the sequence reflects the specified movement and zoom effects, providing a dynamic visual output that can be used in various creative projects. This output is essential for visualizing the animation and integrating it into your artistic workflow.

ImageMotionGuider Usage Tips:

• Experiment with different move_range_x values to achieve the desired horizontal motion effect, keeping in mind that negative values move the image left and positive values move it right.
• Use the zoom parameter to add depth to your animation, but be cautious with high zoom levels as they can distort the image if not used judiciously.
• Adjust the frame_num to balance between animation smoothness and processing time, as more frames will result in a smoother animation but may require more computational resources.

ImageMotionGuider Common Errors and Solutions:

Image size mismatch

• Explanation: This error occurs when the input image dimensions do not match the expected size for processing.
• Solution: Ensure that the input image is correctly formatted and matches the expected dimensions for the node's operations.

Invalid move_range_x value

• Explanation: This error arises when the move_range_x parameter is set outside the allowed range of -150 to 150.
• Solution: Adjust the move_range_x value to fall within the specified range to avoid this error.

Insufficient frame_num

• Explanation: This error happens when the frame_num is set below the minimum value of 2. - Solution: Increase the frame_num to at least 2 to ensure a valid animation sequence.

Excessive zoom level

• Explanation: This error is triggered when the zoom parameter exceeds the maximum value of 0.5.
• Solution: Reduce the zoom value to 0.5 or below to prevent this error and maintain image integrity.
