ComfyUI Node: Schedule Exponential Fade

Schedule Exponential Fade:

The SaltScheduleListExponentialFade node is designed to apply an exponential fade effect to a list of values, which can be particularly useful in audio visualization and other creative AI applications. This node allows you to smoothly transition the values in your schedule list, either fading in, fading out, or both, based on a specified strength. By adjusting the fade type and strength, you can create dynamic and visually appealing effects that enhance the overall presentation of your data. The node ensures that the transition is smooth and gradual, providing a professional touch to your projects.

Schedule Exponential Fade Input Parameters:

schedule_list

The schedule_list parameter is a list of values that you want to apply the exponential fade effect to. This list represents the data points that will be transformed by the node. The values in this list can be any numeric data that you wish to manipulate.

fade_type

The fade_type parameter determines the direction and style of the fade effect. It accepts three options: in, out, and in-and-out. Choosing in will apply a fade-in effect, where values gradually increase in intensity. Selecting out will apply a fade-out effect, where values gradually decrease. The in-and-out option applies both effects, creating a fade-in followed by a fade-out. This parameter allows you to control the overall behavior of the fade effect.

strength

The strength parameter controls the intensity of the exponential fade effect. It is a floating-point value that ranges from 0.01 to 10.0, with a default value of 1.0. A higher strength value will result in a more pronounced fade effect, while a lower value will create a subtler transition. This parameter allows you to fine-tune the fade effect to match your desired outcome.

start_index

The start_index parameter is an optional integer that specifies the starting point in the schedule_list from which the fade effect should begin. It has a minimum value of 0 and a default value of 0. This parameter is useful if you want to apply the fade effect to only a portion of the list, leaving the initial values unchanged.

Schedule Exponential Fade Output Parameters:

schedule_list

The output schedule_list is the transformed list of values after applying the exponential fade effect. This list retains the same length as the input schedule_list, but the values have been adjusted according to the specified fade type and strength. The output list provides the final, faded values that can be used in subsequent nodes or visualizations.

Schedule Exponential Fade Usage Tips:

• To create a smooth fade-in effect, set the fade_type to in and adjust the strength parameter to control the intensity of the fade.
• For a gradual fade-out effect, choose the out option for the fade_type and experiment with different strength values to achieve the desired result.
• Use the in-and-out fade type to create a dynamic effect that starts with a fade-in and transitions to a fade-out, adding visual interest to your data.
• If you only want to apply the fade effect to a specific portion of your list, use the start_index parameter to define the starting point of the fade.

Schedule Exponential Fade Common Errors and Solutions:

"Schedule lists must have the same length."

• Explanation: This error occurs when the input schedule_list does not have the same length as expected.
• Solution: Ensure that the input schedule_list is correctly formatted and contains the expected number of values.

"Invalid fade type."

• Explanation: This error occurs when an invalid value is provided for the fade_type parameter.
• Solution: Check that the fade_type parameter is set to one of the valid options: in, out, or in-and-out.

"Strength value out of range."

• Explanation: This error occurs when the strength parameter is set to a value outside the allowed range of 0.01 to 10.0.
• Solution: Adjust the strength parameter to a value within the specified range to avoid this error.
