How this service works
Adds an AI sound effect to **`video_url`** described by **`prompt`**.
Output
Returns a response containing the processed video or a job ID for async polling, along with status information. In async mode, a webhook URL can be provided to receive the completed result when the sound effect has been applied to the video.
Example use cases
Cinematic ambience for silent footage
“I have a nature clip at https://cdn.example.com/forest.mp4 that has no audio — can you add an AI-generated sound effect described as 'birds chirping and a gentle stream flowing' to bring it to life?”
Horror atmosphere for short film
“Add a creepy sound effect to my video at https://storage.example.com/horror-clip.mp4 — describe it as 'eerie wind howling through a dark corridor with faint footsteps'.”
Action scene audio enhancement
“My action video at https://assets.example.com/chase.mp4 needs punchy sound effects — can you add something like 'car engine roaring and tires screeching on wet asphalt'?”

Endpoint
POSThttps://agents.vimmerse.net/v2/video/sound-effect?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to add AI-generated ambient or thematic sound effects to an existing video clip, driven by a descriptive text prompt. It is ideal for post-production enhancement of silent or audio-poor footage. Use async mode with a webhook for longer videos. Prefer this over a full video generation endpoint when you already have the video and only need audio enhancement.
Side effects
- Invalid or inaccessible video URL returns an error
- Prompt too vague or unsupported may result in poor quality output
- Async job may time out or fail if video is too long or server is busy
- Missing required video_url field returns a 422 validation error
- Payment failure or insufficient credits returns a 402 error
- Webhook URL unreachable may cause silent delivery failure in async mode
