关于 MiniMax H3 First Last Frame LoRA Trainer
根据 `training_data_url` 中的视频片段 zip 文件训练 LoRA,使生成过程可以从一张图像开始并在另一张图像结束。首帧、末帧和双帧的条件概率分别设置。可调参数包括 `rank`(8 到 128)、`number_of_steps`(1 到 15000)、`learning_rate`、`number_of_frames`(22 到 124)和 `aspect_ratio`。返回 LoRA 权重和配置文件。
参数
名称类型
默认值允许值
描述
training_data_url必填
类型string
包含 .mp4、.mov、.avi 或 .mkv 格式训练视频的 ZIP URL;建议至少提供 10 个片段,较大的集合更佳。图像不能作为训练媒体:纯图像数据集,以及将训练图像与视频混合的压缩包都会被拒绝,但某些端点允许图像作为条件侧载资源。片段可以附带可选的说明文件,每个文本文件与其视频共享基本名称。
rank可选
类型enum
默认值32
8163264128
LoRA 适配秩;该值越高,容量越大,但内存消耗也越高。
number_of_steps可选
类型integer
默认值2000
1 – 15,000
训练步数总数。
learning_rate可选
类型number
默认值0.0002
0.000001 – 1
优化学习率,在训练速度可能提升与增大后过拟合风险之间进行权衡。
number_of_frames可选
类型integer
默认值73
22 – 124
每个训练样本的帧数;将其除以 17 后余数必须为 5。示例包括 22、39、56、73、90、107 和 124。
frame_rate可选
类型integer
默认值24
8 – 60
目标视频帧率,以每秒帧数表示。
resolution可选
类型enum
默认值medium
lowmediumhigh
训练分辨率。提高分辨率会增加内存需求。
aspect_ratio可选
类型enum
默认值16:9
21:916:94:31:13:49:16
从 MiniMax H3 API 提供的同一组选项中选择训练宽高比。
trigger_phrase可选
类型string
默认值
LoRA 样式激活短语,训练期间插入字幕开头。
first_frame_conditioning_p可选
类型number
默认值0.2
0 – 1
条件输入仅使用初始帧的概率。
auto_scale_input可选
类型boolean
默认值false
是否通过自动视频缩放匹配目标 fps 和帧数;true 表示启用此调整。
split_input_into_scenes可选
类型boolean
默认值true
超过时长阈值的视频场景拆分;为 true 时启用。
split_input_duration_threshold可选
类型number
默认值30
1 – 60
以秒数表示的场景拆分触发阈值:只有超过该时长的视频才会被拆分。
debug_dataset可选
类型boolean
默认值false
用于在完整训练运行前检查视频、图像和字幕的预处理检查模式。启用后,训练器会将处理后的训练数据集返回为可下载存档,以便手动检查。
strict_dataset可选
类型boolean
默认值false
严格处理预处理问题,否则这些问题会被记录并使用文档所述的回退方案解决。启用后,如果说明需要空提示词、缺少侧载关键帧或视频音频无法读取,请求会被拒绝,而不是分别替换为空提示词、片段帧或静音。
last_frame_conditioning_p可选
类型number
默认值0.2
0 – 1
条件输入仅使用末帧的概率。
first_last_frame_conditioning_p可选
类型number
默认值0.4
0 – 1
训练模式选择概率:其余比例用于无条件文本生成视频音频,指定比例用于 API 中的首帧到末帧关键帧模式,同时以开头帧和结束帧作为联合条件。
