ComfyUI Node: CR Prompt List Keyframes (Legacy)

CR Prompt List Keyframes (Legacy):

The CR Prompt List Keyframes node is designed to help you create a sequence of keyframes from a list of prompts, which can be used in animation workflows. This node is particularly useful for generating smooth transitions between different prompts over a series of frames, making it ideal for creating dynamic and evolving visual content. By specifying a list of prompts and defining keyframe intervals, you can automate the process of keyframe generation, ensuring that your animations are both consistent and visually appealing. This node simplifies the task of managing complex prompt sequences, allowing you to focus on the creative aspects of your project.

CR Prompt List Keyframes (Legacy) Input Parameters:

prompt_list

This parameter accepts a list of prompts that you want to use for generating keyframes. Each prompt in the list should be a string describing the visual elements you want to include at a specific keyframe. The prompts will be used sequentially to create the keyframes, ensuring a smooth transition between different visual elements. There is no strict limit on the number of prompts you can include, but more prompts will result in a more complex and detailed animation.

keyframe_format

This parameter specifies the format of the keyframes to be generated. The available options are Deforum and CR. The Deforum format is commonly used in certain animation tools, while the CR format is specific to the Comfyroll framework. Choosing the appropriate format ensures compatibility with your animation pipeline and tools. The default value is Deforum.

keyframe_interval

This parameter defines the interval between keyframes in terms of the number of frames. A smaller interval will result in more frequent keyframes, leading to smoother transitions but potentially increasing the complexity and rendering time of the animation. The default value is typically set to a reasonable number to balance smoothness and performance.

loops

This parameter determines the number of times the entire prompt list should be looped to generate keyframes. Looping can be useful for creating repetitive or cyclic animations. The default value is usually set to 1, meaning the prompt list will be used once without repetition.

transition_type

This parameter specifies the type of transition to be used between keyframes. Different transition types can create various visual effects, such as linear, ease-in, or ease-out transitions. The choice of transition type can significantly impact the look and feel of your animation.

transition_speed

This parameter controls the speed of the transition between keyframes. A higher value will result in faster transitions, while a lower value will create slower, more gradual changes. Adjusting the transition speed allows you to fine-tune the pacing of your animation.

transition_profile

This parameter defines the profile of the transition, which can include additional settings or curves that influence how the transition progresses over time. The transition profile can add more complexity and nuance to your animations, making them more visually interesting.

CR Prompt List Keyframes (Legacy) Output Parameters:

keyframe_list

This output parameter provides the generated list of keyframes as a string. Each keyframe is represented by a frame number and the corresponding prompt, formatted according to the specified keyframe format. This list can be used directly in your animation tools to create the desired visual sequence.

show_help

This output parameter provides a URL to the documentation or help page for the CR Prompt List Keyframes node. This link can be useful if you need additional information or guidance on how to use the node effectively.

CR Prompt List Keyframes (Legacy) Usage Tips:

• To create smooth and visually appealing animations, experiment with different transition types and speeds to find the best combination for your project.
• Use the loops parameter to create repetitive animations without manually duplicating the prompt list.
• Ensure that your prompt list is well-organized and descriptive to achieve the desired visual effects in your keyframes.

CR Prompt List Keyframes (Legacy) Common Errors and Solutions:

[Error] CR Simple Prompt Scheduler. No lines in keyframe list

• Explanation: This error occurs when the keyframe list is empty or not provided.
• Solution: Ensure that you have specified a valid list of prompts in the prompt_list parameter.

[Warning] CR Simple Prompt Scheduler. Skipped blank line at line {i}

• Explanation: This warning indicates that a blank line was found in the keyframe list and was skipped.
• Solution: Check your prompt list for any unintended blank lines and remove them to avoid this warning.

[Warning] CR Simple Prompt Scheduler. No prompt found for frame. Simple schedules must start at frame 0.

• Explanation: This warning occurs when no prompt is found for the current frame, and the schedule does not start at frame 0.
• Solution: Ensure that your prompt list includes a prompt for frame 0 to avoid this warning.

[Warning] CR Simple Text Scheduler. Invalid keyframe at frame {current_frame}

• Explanation: This warning indicates that an invalid keyframe was found at the specified frame.
• Solution: Check your keyframe list for any formatting errors or invalid entries and correct them.
