ComfyUI Node: Weight Schedule Extend

Weight Schedule Extend:

The WeightScheduleExtend node is designed to help you manage and manipulate weight schedules in your AI art projects. This node allows you to extend or modify the weight schedules, which are crucial for controlling various parameters over time or frames. By using this node, you can ensure that your weight schedules are accurately scaled and adjusted to fit different frame counts, providing you with greater flexibility and control over your creative process. This is particularly useful when working with animations or sequences where the timing and weight of certain effects need to be precisely managed.

Weight Schedule Extend Input Parameters:

input_str

This parameter takes a string that represents the initial weight schedule. The string should be formatted as a series of frame numbers and their corresponding weights, for example, 0:(0.0),\n7:(1.0),\n15:(0.0)\n. This input is crucial as it defines the original schedule that you want to extend or modify. The default value is 0:(0.0),\n7:(1.0),\n15:(0.0)\n.

old_frame_count

This parameter specifies the original number of frames in the weight schedule. It is an integer value that helps the node understand the scale of the initial schedule. The minimum value is 1, the maximum value is 4096, and the default value is 1. This parameter is essential for calculating the scaling factor needed to extend the schedule.

new_frame_count

This parameter defines the new number of frames to which you want to extend the weight schedule. Similar to old_frame_count, it is an integer value with a minimum of 1, a maximum of 4096, and a default value of 1. This parameter allows you to scale the weight schedule to fit a different frame count, providing flexibility in your project.

Weight Schedule Extend Output Parameters:

STRING

The output of this node is a string that represents the extended or modified weight schedule. This string will be formatted similarly to the input string but adjusted to fit the new frame count specified. The output is crucial for applying the new weight schedule to your project, ensuring that the weights are correctly scaled and timed.

Weight Schedule Extend Usage Tips:

• Ensure that your input_str is correctly formatted to avoid errors in processing the weight schedule.
• Use old_frame_count and new_frame_count to accurately scale your weight schedule, especially when working with animations that require precise timing.
• Experiment with different frame counts to see how the weight schedule affects your project, allowing you to fine-tune the results.

Weight Schedule Extend Common Errors and Solutions:

"Invalid input string format"

• Explanation: This error occurs when the input_str is not correctly formatted.
• Solution: Ensure that your input_str follows the required format, such as 0:(0.0),\n7:(1.0),\n15:(0.0)\n.

"Frame count out of range"

• Explanation: This error happens when the old_frame_count or new_frame_count is outside the allowed range of 1 to 4096. - Solution: Adjust the frame counts to be within the valid range of 1 to 4096.

"Scaling factor calculation error"

• Explanation: This error can occur if there is an issue with calculating the scaling factor based on the provided frame counts.
• Solution: Double-check the values of old_frame_count and new_frame_count to ensure they are correct and logical for your project.
