MiniMax H3 Keyframe Plan / 中间关键帧计划 (Advanced):
The MiniMaxH3KeyframePlanT8Advanced node is designed to facilitate the creation of a sophisticated keyframe plan for visual projects, particularly in the context of AI-driven animation or video generation. This node allows you to chain a middle timeline image with a specific frame, second, or percentage position, along with a raw per-frame H3 visual noise-augmentation value. By doing so, it provides a high degree of control over the timing and visual effects applied to keyframes, enabling more precise and creative manipulation of visual sequences. The node is particularly beneficial for artists looking to integrate complex visual noise patterns and timing into their projects, offering a structured approach to managing multiple keyframes within a timeline.
MiniMax H3 Keyframe Plan / 中间关键帧计划 (Advanced) Input Parameters:
previous_plan
This optional parameter allows you to connect a previously created Advanced Keyframe Plan to build upon an existing timeline. It helps in maintaining continuity and coherence across multiple keyframes, ensuring that the new keyframe integrates seamlessly with the existing plan.
image
This parameter represents the middle timeline keyframe image. It is crucial as it defines the visual content that will be placed at the specified position in the timeline. The node uses batch item 0 of the image input, which means the first image in a batch is considered for processing.
position_mode
This parameter determines how the position of the keyframe is specified. It offers three options: "frame," "seconds," and "percent." The default is "frame." Choosing "percent" uses an explicit 0 to 100 scale, avoiding any ambiguity that might arise from using a 0 to 1 scale. This flexibility allows you to specify the keyframe's position in a way that best suits your project's needs.
position
This parameter specifies the exact position of the keyframe within the timeline. It can be defined in terms of absolute 24fps frames, seconds, or a percentage, depending on the position_mode selected. The default value is 62.0, with a range from 0.0 to 3600.0. It is important that this value resolves strictly between the first and last keyframes to ensure proper sequencing.
visual_noise_aug
This parameter allows you to specify a raw per-frame H3 visual noise-augmentation value. It is used to apply visual noise effects to the keyframe, enhancing the visual complexity and artistic expression of the sequence.
resize_mode
This parameter determines how the image should be resized to fit the timeline or other constraints. It ensures that the keyframe image is appropriately scaled, maintaining the desired visual quality and aspect ratio.
enabled
This boolean parameter indicates whether the keyframe should be active in the timeline. It allows you to toggle the inclusion of the keyframe without removing it from the plan, providing flexibility in managing the timeline's content.
MiniMax H3 Keyframe Plan / 中间关键帧计划 (Advanced) Output Parameters:
keyframe_plan
The output parameter keyframe_plan represents the constructed keyframe plan, which includes the newly added keyframe along with any previous ones. This plan is essential for defining the sequence and timing of keyframes in your project, serving as a blueprint for the visual timeline.
MiniMax H3 Keyframe Plan / 中间关键帧计划 (Advanced) Usage Tips:
- Ensure that the
positionparameter is set within the valid range and resolves between the first and last keyframes to maintain a coherent timeline. - Utilize the
visual_noise_augparameter to experiment with different noise patterns, adding unique visual effects to your keyframes. - Use the
previous_planinput to build upon existing timelines, allowing for complex and layered visual sequences.
MiniMax H3 Keyframe Plan / 中间关键帧计划 (Advanced) Common Errors and Solutions:
"keyframe_plan must be an H3 T8 keyframe plan"
- Explanation: This error occurs when the provided keyframe plan is not of the expected type or format.
- Solution: Ensure that the input plan is a valid H3 T8 keyframe plan and not a string or bytes object.
"MiniMax H3 Advanced supports at most {MAX_MIDDLE_KEYFRAMES} middle keyframes"
- Explanation: This error indicates that the number of middle keyframes exceeds the maximum allowed limit.
- Solution: Reduce the number of middle keyframes in your plan to comply with the maximum limit specified by the node.
