ComfyUI Node: 📑 CR Text Scheduler

📑 CR Text Scheduler:

The CR Text Scheduler is a versatile node designed to manage and automate the scheduling of text outputs based on specific frames in an animation sequence. This node is particularly useful for AI artists who need to dynamically change text content at different points in their animations. By leveraging keyframe scheduling, the CR Text Scheduler allows you to define text changes at precise frames, ensuring that your animations are synchronized with the desired textual content. This node can handle both default text and scheduled text changes, providing flexibility and control over your animation projects. The primary goal of the CR Text Scheduler is to streamline the process of text management in animations, making it easier to create complex and engaging visual narratives.

📑 CR Text Scheduler Input Parameters:

mode

The mode parameter determines the operational mode of the scheduler. It can be set to "Default Text" or "Keyframe List". When set to "Default Text", the scheduler is disabled, and the default text is used throughout the animation. When set to "Keyframe List", the scheduler uses the provided keyframe list to change the text at specified frames. This parameter is crucial for defining how the text changes are managed during the animation.

current_frame

The current_frame parameter specifies the current frame of the animation. This parameter is used to determine which text should be displayed based on the keyframe schedule. It is essential for synchronizing text changes with the animation frames.

schedule_alias

The schedule_alias parameter is a unique identifier for the schedule. It helps in managing and referencing different schedules within the animation project. This alias is used internally to track and apply the correct text changes at the specified frames.

default_text

The default_text parameter provides the default text to be used when the scheduler is in "Default Text" mode or when no specific text is scheduled for a frame. This ensures that there is always a fallback text available, preventing any gaps in the animation.

schedule_format

The schedule_format parameter defines the format of the keyframe list. It can be set to different formats, such as "Deforum", to accommodate various scheduling styles. This parameter ensures that the keyframe list is correctly interpreted and applied.

schedule

The schedule parameter contains the keyframe list that defines the text changes at specific frames. This list is parsed and used to determine the text output for each frame. It is a critical input for enabling dynamic text changes in the animation.

📑 CR Text Scheduler Output Parameters:

text_out

The text_out parameter is the resulting text output based on the current frame and the keyframe schedule. It provides the text that should be displayed at the specified frame, ensuring that the animation is synchronized with the desired textual content.

show_help

The show_help parameter provides a URL to the documentation or help page for the CR Text Scheduler. This is useful for users who need additional information or guidance on how to use the node effectively.

📑 CR Text Scheduler Usage Tips:

• To ensure smooth text transitions in your animation, carefully plan and define your keyframe list, specifying the exact frames where text changes should occur.
• Use the default_text parameter to provide a fallback text that will be displayed when no specific text is scheduled for a frame, preventing any gaps in your animation.
• Experiment with different schedule_format options to find the one that best suits your scheduling style and project requirements.

📑 CR Text Scheduler Common Errors and Solutions:

No frame 0 found in schedule

• Explanation: This warning indicates that there is no keyframe defined for frame 0 in the schedule.
• Solution: Ensure that your keyframe list includes a definition for frame 0 to avoid starting the animation without an initial text value.

Invalid params: <params>

• Explanation: This warning occurs when the parameters provided in the keyframe list are invalid or cannot be parsed.
• Solution: Check the keyframe list for any syntax errors or incorrect formatting and correct them to ensure the parameters are valid.

Scheduler <schedule_alias> is disabled

• Explanation: This information message indicates that the scheduler is in "Default Text" mode and is not using the keyframe list.
• Solution: If you want to use the keyframe list, change the mode parameter to "Keyframe List".
