ComfyUI Node: CR Simple Prompt List Keyframes (Legacy)

CR Simple Prompt List Keyframes (Legacy):

The CR Simple Prompt List Keyframes node is designed to facilitate the creation of keyframes from a list of simple prompts for animation purposes. This node is particularly useful for AI artists who want to generate smooth transitions between different prompts over a series of frames. By specifying a list of prompts and defining keyframe intervals, loops, and transition types, you can create a sequence of keyframes that can be used to animate your AI-generated art. The node simplifies the process of keyframe generation, making it accessible even to those without a deep technical background, and provides a link to detailed documentation for further assistance.

CR Simple Prompt List Keyframes (Legacy) Input Parameters:

simple_prompt_list

This parameter accepts a list of prompts that you want to use for generating keyframes. Each prompt in the list represents a specific frame in the animation sequence. The prompts should be provided as strings, and the list can be as long as needed to cover the desired animation duration. The quality and coherence of the animation depend on the creativity and relevance of the prompts provided.

keyframe_interval

This parameter defines the interval between consecutive keyframes. It determines how many frames will be skipped before the next keyframe is generated. A smaller interval results in more frequent keyframes, leading to smoother transitions, while a larger interval creates more abrupt changes. The value should be a positive integer, with a default value typically set to ensure a balance between smoothness and performance.

loops

This parameter specifies the number of times the entire prompt list should be looped to create the keyframes. It allows you to repeat the sequence of prompts multiple times, which can be useful for creating longer animations without manually extending the prompt list. The value should be a positive integer, with a default value that ensures at least one complete loop.

transition_type

This parameter defines 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 available options are usually predefined and can be selected based on the desired animation style.

transition_speed

This parameter controls the speed of the transition between keyframes. It affects how quickly the animation moves from one prompt to the next. A higher speed results in faster transitions, while a lower speed creates slower, more gradual changes. The value should be a positive number, with a default value that provides a balanced transition speed.

transition_profile

This parameter allows you to specify a profile for the transition, which can include additional settings or curves that define the transition behavior. The profile can be used to fine-tune the animation and achieve specific visual effects. The available profiles are usually predefined and can be selected based on the desired outcome.

keyframe_format

This parameter specifies the format of the keyframes to be generated. The available options typically include formats like "Deforum" and "CR," which define how the keyframes are structured and interpreted by the animation system. The default format is usually set to ensure compatibility with common animation tools.

CR Simple Prompt List Keyframes (Legacy) Output Parameters:

keyframes_out

This output parameter provides the generated keyframes as a string. The keyframes are formatted according to the specified keyframe format and can be used directly in animation tools or further processed for custom applications. The output string includes all the keyframes created based on the input parameters, ensuring a seamless animation sequence.

show_help

This output parameter provides a URL link to the detailed documentation for the CR Simple Prompt List Keyframes node. The documentation includes additional information, examples, and troubleshooting tips to help you make the most of the node's capabilities. It is a valuable resource for understanding the node's functionality and resolving any issues that may arise.

CR Simple Prompt List Keyframes (Legacy) Usage Tips:

• Experiment with different keyframe intervals to find the right balance between smooth transitions and performance.
• Use the loops parameter to extend the animation duration without manually duplicating the prompt list.
• Select appropriate transition types and profiles to achieve the desired visual effects in your animation.
• Refer to the provided documentation link for detailed examples and advanced usage scenarios.

CR Simple 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, meaning no prompts were provided for generating keyframes.
• Solution: Ensure that the simple_prompt_list parameter contains at least one prompt.

[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 during processing.
• Solution: Check the simple_prompt_list for any 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, which can happen if the schedule does not start at frame 0.
• Solution: Ensure that the keyframe list starts with a prompt at frame 0 to avoid this issue.

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

• Explanation: This warning indicates that an invalid keyframe was encountered at the specified frame, possibly due to incorrect formatting.
• Solution: Verify the format of the keyframes and ensure they are correctly structured according to the specified keyframe format.
