ComfyUI Node: Prompt Travel Helper

Prompt Travel Helper:

The PromptTravelHelper node is designed to assist in the creation and manipulation of text prompts for animation workflows. This node is particularly useful for generating sequences of prompts that can be used to create smooth transitions and hold frames in animations. By processing bulk text input, it allows you to define how long each prompt should be held and the duration of transitions between prompts. This functionality is essential for creating dynamic and engaging animations where text prompts change over time, providing a seamless and professional look to your projects.

Prompt Travel Helper Input Parameters:

bulk_text_input

This parameter accepts a multiline string input where each line represents a different prompt. The node processes these prompts to create a sequence for animation. If the input is empty or only contains whitespace, the node will return an empty result. This parameter is crucial as it defines the content that will be animated. The default value is an empty string.

hold_length

This integer parameter specifies the number of frames each prompt should be held before transitioning to the next prompt. A higher value means the prompt will stay on the screen longer, while a lower value will make the animation faster. The default value is 5, with a minimum value of 0.

transition_length

This integer parameter determines the number of frames used for transitioning between prompts. A higher value will create a slower, smoother transition, while a lower value will make the transition quicker. The default value is 5, with a minimum value of 0.

end_padding_frames

This integer parameter adds extra frames at the end of the animation sequence, ensuring that the final prompt has a bit of extra time before the loop restarts. This can be useful for giving the viewer a moment to absorb the final prompt. The default value is 10, with a minimum value of 0.

Prompt Travel Helper Output Parameters:

formatted_prompts

This output parameter returns a formatted string that represents the sequence of prompts along with their corresponding frame numbers. The output is structured in a way that can be easily used in animation tools to create the desired effect. Each frame number is associated with one or more prompts, ensuring that the animation follows the specified hold and transition lengths.

Prompt Travel Helper Usage Tips:

• Ensure that your bulk_text_input is well-structured with each prompt on a new line to avoid any formatting issues.
• Adjust the hold_length and transition_length parameters to fine-tune the pacing of your animation. For a slower, more dramatic effect, increase these values.
• Use the end_padding_frames parameter to add a natural pause at the end of your animation loop, giving viewers time to read the final prompt.

Prompt Travel Helper Common Errors and Solutions:

Empty input string

• Explanation: The bulk_text_input parameter is empty or contains only whitespace.
• Solution: Ensure that you provide a valid multiline string with each prompt on a new line.

Invalid hold_length or transition_length

• Explanation: The hold_length or transition_length parameters are set to negative values.
• Solution: Set these parameters to non-negative integers. The minimum value allowed is 0.

Unexpected formatting in output

• Explanation: The bulk_text_input contains unescaped special characters like quotes.
• Solution: Ensure that all special characters in your prompts are properly escaped. For example, use \\" to escape double quotes.
