Model overview
视频延长是指对文生/图生视频结果进行时间上的延长，单次可延长4~5s，使用的模型和模式不可选择、与源视频相同；价格与原视频模式有关，std 1倍，pro 3.5倍
The summary below is compiled from sources by an AI model, not our own testing. Verify selection decisions against original sources and your workload.
Key features
- 支持对文生视频或图生视频结果进行时间维度延长，单次延长时长为4~5秒
- 延长过程自动复用源视频所用的模型和生成模式，无需用户手动选择
- 任务以异步方式执行，适用于视频类长周期处理场景
Limitations & considerations
- 不支持自定义延长所用的模型或生成模式
- 单次延长时长固定为4~5秒，不可调节
- 价格与原始视频生成模式强绑定（std为1倍、pro为3.5倍），无独立定价选项

视频延长是否支持更改模型或生成参数？
不支持。延长过程强制复用源视频的模型和模式，无法更改。
单次延长能超过5秒吗？
不能。单次延长严格限定在4~5秒范围内，不可调整。
延长任务的计费规则是怎样的？
计费与原始视频生成模式挂钩：std模式下延长费用为原价1倍，pro模式下为原价3.5倍。
Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
