How this service works
Attaches **`audio_url`** to **`video_url`**. **`attach_mode`:** `MatchVideo`, `PadAudio`, `MatchAudio`, `SpeedAdjust`, `Strict`
Output
A processed video file with the specified audio track attached, returned either synchronously as a result URL or asynchronously as a job ID that can be polled for completion. The response includes the output video URL once processing finishes.
Example use cases
Background music for a promo video
“I have a product promo video at https://cdn.example.com/promo.mp4 and a music file at https://cdn.example.com/bgmusic.mp3 — can you attach the music to the video using MatchVideo mode so it fits the video perfectly?”
Voiceover narration on a slideshow
“Please attach my recorded narration at https://storage.example.com/narration.wav to the slideshow video at https://storage.example.com/slides.mp4 using Strict mode — both are exactly 60 seconds.”
Speed-adjust audio to match video
“I've got a 90-second video at https://media.example.com/clip.mp4 and a 75-second song at https://media.example.com/song.mp3. Attach the audio to the video using SpeedAdjust mode so the song stretches to fill the full video.”
Technical details
Endpoint
POSThttps://agents.vimmerse.net/v2/video/audio?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to combine a separate audio file (music, voiceover, sound effects) with a video and require precise control over how duration mismatches are handled — choose from five attach modes (MatchVideo trims/loops audio, PadAudio pads audio with silence, MatchAudio trims video, SpeedAdjust changes playback speed, Strict enforces exact duration match). Prefer this over manual video editing tools when automating media pipelines or when the audio and video durations may differ.
Side effects
- Invalid or inaccessible video_url or audio_url (404 or permission errors)
- Unsupported media format for video or audio input
- Strict mode failure when durations do not match exactly
- Timeout on large files in synchronous mode
- Webhook delivery failure in async mode
- Insufficient credits to process the request
