ComfyUI Node: Fade Between Batches | Akatz

Fade Between Batches | Akatz:

The AK_FadeBetweenBatches node is designed to seamlessly blend two batches of images by creating a smooth transition between them. This node is particularly useful for AI artists who want to create animations or visual effects that require a gradual change from one image sequence to another. By specifying a number of overlapping frames, the node generates a series of transition frames that fade from the first image batch to the second. This process ensures a fluid and visually appealing transition, enhancing the overall aesthetic of your project. The node automatically handles differences in image dimensions by resizing the second batch to match the first, ensuring consistency across the transition. This capability makes it an essential tool for creating dynamic and engaging visual content without requiring extensive technical knowledge.

Fade Between Batches | Akatz Input Parameters:

image1

image1 is the first batch of images that will be used as the starting point for the transition. This parameter is crucial as it defines the initial visual content from which the transition begins. The images in this batch should be consistent in terms of dimensions and channels to ensure a smooth transition. There are no specific minimum or maximum values for this parameter, but it should not be None or empty.

image2

image2 is the second batch of images that will be used as the endpoint for the transition. This parameter is essential as it defines the final visual content to which the transition will lead. Like image1, the images in this batch should be consistent in terms of dimensions and channels. If the dimensions differ from image1, the node will automatically resize image2 to match. This parameter should also not be None or empty.

overlap_frames

overlap_frames determines the number of frames over which the transition will occur. This parameter directly impacts the smoothness and duration of the transition. A higher number of overlap frames results in a more gradual and smoother transition, while a lower number creates a quicker change. The default value is 10, with a minimum of 1. There is no specified maximum, but it should not exceed the batch sizes of the input images.

Fade Between Batches | Akatz Output Parameters:

IMAGE

The output is a single batch of images that includes the initial frames from image1, the transition frames, and the final frames from image2. This output represents the complete sequence of images with a smooth transition between the two input batches. The resulting batch maintains the dimensions and channels of the input images, providing a cohesive and visually appealing sequence that can be used in various creative projects.

Fade Between Batches | Akatz Usage Tips:

• Ensure that both image1 and image2 have the same dimensions and channels to avoid unexpected resizing and maintain visual consistency.
• Experiment with different values for overlap_frames to achieve the desired transition effect. A higher number of overlap frames will create a smoother transition.
• Use this node to create engaging animations or visual effects by blending different image sequences seamlessly.

Fade Between Batches | Akatz Common Errors and Solutions:

Both image1 and image2 are None or empty.

• Explanation: This error occurs when both input image batches are either not provided or are empty.
• Solution: Ensure that both image1 and image2 are valid image batches with content before executing the node.

Overlap frames exceed the batch sizes of the input images.

• Explanation: This error happens when the specified number of overlap frames is greater than the number of frames in either image1 or image2.
• Solution: Adjust the overlap_frames parameter to be less than or equal to the number of frames in the smaller batch to avoid this error.
