ComfyUI Node: Image Compare Transition

Image Compare Transition:

The ImageCompareTransition node is designed to create a smooth transition between two images by generating a series of intermediate frames. This node is particularly useful for creating animations or visual effects where a gradual change from one image to another is desired. By specifying the number of frames and the frames per second (fps), you can control the smoothness and speed of the transition. This node is beneficial for artists looking to add dynamic visual elements to their projects, as it automates the process of blending two images over a specified duration, resulting in a seamless visual transformation.

Image Compare Transition Input Parameters:

image1

image1 is the first image in the transition sequence. It serves as the starting point of the transition. The node will gradually blend this image into the second image, image2, over the specified number of frames. This parameter is crucial as it defines the initial visual state of the transition.

image2

image2 is the second image in the transition sequence. It represents the final state of the transition. The node will blend the first image, image1, into this image, creating a smooth transition effect. This parameter is essential as it determines the end visual state of the transition.

frames

The frames parameter specifies the number of intermediate frames to generate between image1 and image2. It controls the smoothness of the transition; more frames result in a smoother transition. The default value is 30, with a minimum of 2 and a maximum of 120. Adjusting this parameter allows you to fine-tune the transition's visual fluidity.

fps

The fps (frames per second) parameter determines the playback speed of the transition. It affects how quickly the transition appears to occur when played back. The default value is 8.0, with a minimum of 1.0 and a maximum of 60.0. This parameter is important for synchronizing the transition with other elements in your project or achieving the desired visual pacing.

Image Compare Transition Output Parameters:

output_frames

The output_frames parameter is a tensor containing all the generated frames of the transition. Each frame represents a step in the transition from image1 to image2. This output is crucial for creating animations or visual effects, as it provides the complete sequence of images needed to visualize the transition. The frames are clamped to ensure they remain within the correct visual range, maintaining image quality.

Image Compare Transition Usage Tips:

• To achieve a smoother transition, increase the frames parameter to generate more intermediate frames, which will create a more gradual blend between the two images.
• Adjust the fps parameter to control the speed of the transition. A higher fps will result in a faster transition, while a lower fps will slow it down, allowing for more detailed observation of the transition process.

Image Compare Transition Common Errors and Solutions:

Video file not found

• Explanation: This error occurs when the specified video file for previewing the transition is not found in the given path.
• Solution: Ensure that the video file path is correct and that the file exists in the specified location. Double-check the file name and extension for any typos.

Unsupported blend mode

• Explanation: This error arises when an invalid blend mode is specified during the transition process.
• Solution: Verify that the blend mode used is supported by the node. Refer to the documentation for a list of valid blend modes and ensure that the correct one is selected.
