- Class name: WeightAdjustIndivAttnMultNode
- Category: Animate Diff 🎭🅐🅓
- Output node: False
- Repo Ref: https://github.com/Kosinkadink/ComfyUI-AnimateDiff-Evolved.git
最初设计用于将多个动画帧组合成一个连贯的序列，此节点有助于从单个帧创建复杂的动画。
Input types
Required
-
images
- 一个动画帧集合，组合成单个序列，支持从单个帧创建复杂的动画。
- Comfy dtype: IMAGE
- Python dtype: List[Image.Image]
-
frame_rate
- 指定组合动画序列的播放速度，决定帧的显示速度。
- Comfy dtype: INT
- Python dtype: int
-
loop_count
- 定义动画序列的重复次数，值为0表示无限循环。
- Comfy dtype: INT
- Python dtype: int
-
filename_prefix
- 输出文件名的前缀，有助于组织和识别生成的动画。
- Comfy dtype: STRING
- Python dtype: str
-
format
- 输出动画文件的格式，例如GIF，允许自定义输出类型。
- Comfy dtype: COMBO[STRING]
- Python dtype: str
-
pingpong
- 一个布尔值，指示动画是否应前后播放，创建无缝循环效果。
- Comfy dtype: BOOLEAN
- Python dtype: bool
-
save_image
- 确定是否将组合的动画序列保存为图像文件，提供灵活的输出处理方式。
- Comfy dtype: BOOLEAN
- Python dtype: bool
Output types
- gif
- 生成的动画文件，根据指定参数组合输入帧。
- Comfy dtype: GIF
- Python dtype: str
