ComfyUI Node: 🔶 Load Checkpoint +Frame CKPT_PROMPT

🔶 Load Checkpoint +Frame CKPT_PROMPT:

The chaosaiart_CheckpointPrompt_Frame node is designed to streamline the process of loading specific checkpoints and associated prompts based on frame numbers. This node is particularly useful for AI artists who work with animations or sequences, as it allows for dynamic changes in checkpoints and prompts as the frame number progresses. By specifying a starting frame, a checkpoint, and positive and negative prompts, you can ensure that your model uses the appropriate settings for each frame. This node also supports optional LoRA (Low-Rank Adaptation) models, which can further refine the output by adding specialized layers to the model. The primary goal of this node is to provide a flexible and efficient way to manage checkpoints and prompts, enhancing the creative workflow for AI-generated art.

🔶 Load Checkpoint +Frame CKPT_PROMPT Input Parameters:

Start_Frame

This parameter specifies the starting frame number from which the checkpoint and prompts will be applied. It is an integer value with a minimum of 1 and a maximum of 1,000,000,000, with a default value of 1. The Start_Frame parameter is crucial for synchronizing the checkpoint and prompts with the correct frame in your animation or sequence.

Checkpoint

This parameter allows you to select the checkpoint file from a list of available checkpoints. The checkpoint is a pre-trained model that will be loaded and used for generating the output. The selection is made from the filenames available in the "checkpoints" directory. Choosing the right checkpoint is essential for achieving the desired style and quality in your AI-generated art.

Positiv

This parameter is a multiline string where you can input the positive prompts. Positive prompts are phrases or keywords that guide the model towards generating desired features in the output. This parameter allows for detailed and specific instructions to be given to the model, enhancing the creative control you have over the generated art.

Negativ

This parameter is a multiline string for inputting negative prompts. Negative prompts are phrases or keywords that instruct the model to avoid certain features or styles in the output. By providing negative prompts, you can refine the output by excluding unwanted elements, ensuring that the generated art aligns more closely with your vision.

lora

This optional parameter allows you to include LoRA (Low-Rank Adaptation) models. LoRA models are used to add specialized layers to the main model, enabling more refined and targeted adjustments to the output. This parameter accepts an array of LoRA models, providing additional flexibility and control over the generated art.

🔶 Load Checkpoint +Frame CKPT_PROMPT Output Parameters:

CKPT_PROMPT

The output parameter CKPT_PROMPT is a composite object that includes the starting frame, checkpoint, positive prompts, negative prompts, and optional LoRA models. This output is used to configure the model for generating art based on the specified settings. The CKPT_PROMPT ensures that all necessary components are bundled together, making it easier to manage and apply the settings across different frames in your animation or sequence.

🔶 Load Checkpoint +Frame CKPT_PROMPT Usage Tips:

• Ensure that the Start_Frame parameter is set correctly to synchronize the checkpoint and prompts with the appropriate frame in your animation.
• Use detailed and specific positive and negative prompts to guide the model towards generating the desired output.
• Experiment with different checkpoints to find the one that best suits your artistic vision.
• Utilize the optional LoRA parameter to add specialized layers to the model for more refined adjustments.

🔶 Load Checkpoint +Frame CKPT_PROMPT Common Errors and Solutions:

Chaosaiart - CheckpointPrompt_FrameMixer: no checkpoint_prompt_frame with this Activ_Frame. checkpoint_prompt_frame1 will be Used

• Explanation: This error occurs when the specified frame does not have an associated checkpoint and prompt.
• Solution: Ensure that the frame number specified in Start_Frame has a corresponding checkpoint and prompt defined. If not, the default checkpoint and prompt will be used.

Checkpoint file not found

• Explanation: This error occurs when the specified checkpoint file is not available in the "checkpoints" directory.
• Solution: Verify that the checkpoint file exists in the "checkpoints" directory and that the filename is correctly specified in the Checkpoint parameter.

Invalid frame number

• Explanation: This error occurs when the Start_Frame parameter is set to a value outside the allowed range.
• Solution: Ensure that the Start_Frame parameter is set to an integer value between 1 and 1,000,000,000.

LoRA model loading failed

• Explanation: This error occurs when the specified LoRA model cannot be loaded.
• Solution: Verify that the LoRA model files are correctly specified and available in the appropriate directory. Ensure that the model files are not corrupted.
