ComfyUI Node: CR Cycle Images (Legacy)

CR Cycle Images (Legacy):

The CR Cycle Images node is designed to facilitate the sequential cycling of images within an animation or a series of frames. This node is particularly useful for AI artists who want to create dynamic visual sequences by looping through a set of images in a specified order. By leveraging this node, you can automate the process of switching between images at defined intervals, making it easier to manage and control the flow of your animation. The primary goal of this node is to enhance the creative process by providing a straightforward method to cycle through images, thereby adding variety and movement to your projects.

CR Cycle Images (Legacy) Input Parameters:

mode

The mode parameter determines the cycling method used for the images. Currently, the supported mode is "Sequential," which cycles through the images in the order they are provided. This parameter is crucial as it defines how the images will be displayed over time. The default value is "Sequential."

image_list

The image_list parameter is a list of images that you want to cycle through. Each item in this list should be an image that you wish to include in the sequence. This parameter is essential as it provides the content that will be cycled through during the animation. There is no default value, and it must be provided by the user.

frame_interval

The frame_interval parameter specifies the number of frames to display each image before moving to the next one. This parameter controls the speed of the cycling process. A lower value will result in faster cycling, while a higher value will slow it down. The default value is not specified and should be set according to the desired animation speed.

loops

The loops parameter indicates how many times the entire image list should be repeated. This parameter allows you to extend the duration of the animation by looping through the images multiple times. The default value is not specified and should be set based on the desired length of the animation.

current_frame

The current_frame parameter represents the current frame number in the animation. This parameter is used to calculate which image should be displayed at any given time. It is essential for synchronizing the image cycling with the overall animation timeline. The default value is not specified and should be updated dynamically as the animation progresses.

CR Cycle Images (Legacy) Output Parameters:

current_image_item

The current_image_item output parameter is the image that should be displayed at the current frame. This parameter provides the actual image content that will be shown in the animation, based on the cycling logic defined by the input parameters. It is crucial for rendering the correct image at the right time.

show_help

The show_help output parameter is a URL link to the documentation or help page for the CR Cycle Images node. This parameter is useful for users who need additional information or guidance on how to use the node effectively. It provides a quick reference to the official documentation.

CR Cycle Images (Legacy) Usage Tips:

• To create a smooth animation, ensure that the frame_interval is set appropriately based on the frame rate of your project.
• Use the loops parameter to extend the duration of your animation without having to manually duplicate the image list.
• Keep the current_frame parameter updated in real-time to ensure that the correct image is displayed at each frame.

CR Cycle Images (Legacy) Common Errors and Solutions:

IndexError: list index out of range

• Explanation: This error occurs when the current_frame and frame_interval combination results in an index that exceeds the length of the image_params list.
• Solution: Ensure that the frame_interval and loops parameters are set correctly so that the calculated index stays within the bounds of the image_params list.

TypeError: 'NoneType' object is not iterable

• Explanation: This error occurs when the image_list parameter is not provided or is set to None.
• Solution: Make sure to provide a valid list of images in the image_list parameter.

ValueError: mode not supported

• Explanation: This error occurs when an unsupported value is provided for the mode parameter.
• Solution: Ensure that the mode parameter is set to "Sequential," as it is the currently supported mode.
