幂等性
为每次修改操作在 requestId 或 Idempotency-Key HTTP 请求头中提供 UUID v4。网络故障后，请使用相同标识符和完全相同的参数重试。如果同时提供这两个值，它们必须一致。重放已保存的请求不会重复执行操作，也不会再次扣除月度调用次数。失败或中断的请求不会自动重新执行。 对于每次修改操作，如果重试时发现同一请求仍在运行，即使首次执行通常为同步操作，也可能返回 HTTP 202。如果执行已完成但 resultStored 为 false，重试会返回 HTTP 200 和已保存的请求状态，而非原始结果。请通过对应领域的历史记录、结果或下载操作获取输出。请求示例
请将示例资源标识符和媒体键替换为账户返回的值。重试同一次修改操作时，请保持请求标识符不变。curl --request POST 'https://api.voicecheap.ai/v1/actions/subtitles_dynamic_create' \

操作说明
- templateName 为受支持的模板名称。videoSource 默认为 translated；lip-synced 选择最新已完成且已存储的口型同步视频。不接受调用者提供的媒体 URL。
- 所选版本必须已完成，且所选视频必须可用。支持 MP4 和 MOV；已存储的项目时长不得超过 2 小时，存储字节大小不得超过 2 GiB。
- magicZooms 和 magicBrolls 默认为 false；magicBrollsPercentage 默认为 0。可选的 removeSilencePace 接受 natural、fast 或 extra-fast；removeBadTakes 为布尔值。
- 语言取自已获授权的语言内容。仍需进行常规套餐限额和媒体额度检查；每个翻译版本只能重新生成一次动态字幕。
- 这是一个长时间运行的操作。先轮询 action_request_get 等待处理完成，再查看 projects_get.translations[].dynamicSubtitles 中的 inProgress、videoUrl 和 errorMessage。projects_status 不公开此动态字幕状态。
