Video Sound Effects API 调用参考
按你的视频配上音效和环境声
用一个 PopNow API 密钥，就能在自己的代码里调用 Video Sound Effects。下面列出要填的调用名、这个型号接受的每个输入字段、每次请求花多少积分，以及一段可以直接粘进终端运行的请求。
参数说明直接取自型号的输入 schema，暂时只有英文。

- 0.18 积分 每秒成片 ($0.0018)
1 积分 = 0.01 美元。任务受理时先冻结可能的最高费用，完成后按实际用量结算、向上取整到整积分，多冻的退回；失败的任务不扣积分。想在运行前知道确切数字，先调 POST /api/v1/jobs/quote。

参数
| 字段 | 类型 | 默认值 | 取值范围 | 作用 |
|---|---|---|---|---|
video_url必填 | string | — | — | Clip to add sound to. The picture is kept; the returned clip carries the generated sound as its audio. |
prompt可选 | string | — | 最多 1000 个字符 | The sounds you want, as a short list. If omitted, a general request for sounds that match the on-screen action is used. |
duration_seconds可选 | integer | 8 | 1 到 30 | Seconds of sound to generate, from 1 to 30. The returned clip is cut to this length and these seconds are billed. |
negative_prompt可选 | string | — | 最多 1000 个字符 | Sounds to keep out, such as music or speech. |
ignore_visual_semantics可选 | boolean | false | — | Choose the sounds from the prompt alone instead of from what the picture shows; timing still follows the motion. |
guidance_scale可选 | number | 4.5 | 0 到 20 | How closely the sound follows the description, from 0 to 20. |
steps可选 | integer | 25 | 4 到 50 | Refinement passes, from 4 to 50. More passes take longer. |
请求示例
这段请求原样就能运行，没写的字段都用默认值。运行前先把密钥放进环境变量 POPNOW_API_KEY。
示例里的 video_url 用的是 PopNow 的示例素材，换成你自己的公开 HTTPS 链接、上传文件或已保存的素材即可。
curl -X POST "https://api.popnow.ai/api/v1/jobs/createTask" \
-H "Authorization: Bearer $POPNOW_API_KEY" \
-H "Content-Type: application/json" \
-H "Idempotency-Key: $(uuidgen)" \
-d '{
"model": "popnow/foley-v1/video-to-audio",
"input": {
"prompt": "Soft wind, rustling petals and distant birdsong",
"video_url": "https://media.popnow.ai/effects/flower-bloom-1abd6efb.mp4",
"duration_seconds": 8
}
}'响应里会立刻带回 taskId。之后用 GET /api/v1/jobs/recordInfo 取结果，或者在请求里加上 callBackUrl 等通知。
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=TASK_ID_FROM_CREATE_TASK" \
-H "Authorization: Bearer $POPNOW_API_KEY"
