VEED Lipsync V2 generates production-quality lip-synced video from a source video and replacement audio track. Upload a video with a visible speaker, provide the new audio, and the model produces a video where the mouth movement follows the supplied audio.
Production-quality lipsync Generate natural mouth movement that follows the replacement audio track.
Simple video-to-video workflow Provide one source video and one audio file without extra tuning parameters.
Audio-driven duration The output video follows the uploaded audio duration.
Standard video output The generated video is returned as a URL in the standard WaveSpeed prediction response.
| Parameter | Required | Description |
|---|---|---|
| video | Yes | Source video containing the face to be lip-synced. |
| audio | Yes | Audio track that drives the mouth movement. |
Pricing is $0.075 per second of uploaded audio duration, rounded up to the next full second.
| Audio Duration | Price |
|---|---|
| 5s | $0.375 |
| 10s | $0.75 |
| 30s | $2.25 |
| 60s | $4.50 |
Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/veed/lipsync-v2 with your input as JSON. The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read output values from data.outputs. Examples for Lipsync v2 below.

time.sleep(2)Lipsync v2 is a Veed model for talking-avatar generation, exposed as a REST API on WaveSpeedAI. VEED Lipsync V2 generates production-quality lip-synced videos from a source video and a replacement audio track, matching mouth movements to the new audio for dubbing, localization, creator content, and talking-video workflows. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID. Poll the result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates production-oriented Python, JavaScript, and cURL examples with timeouts, transient-error handling, and safe GET retries. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/veed/veed-lipsync-v2.
Lipsync v2 starts at $0.075 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
Key inputs: `video`, `audio`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/veed/veed-lipsync-v2.
Median end-to-end generation time on WaveSpeedAI is around 47 seconds per request, based on recent successful runs. Queue time varies with global demand; live status is visible in the prediction record.
Commercial usage rights depend on the model's license, set by its provider (Veed). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
