Topaz Labs Video Upscale Serverless API

Topaz Video AI upscales, enhances, denoises, stabilizes, and increases frame rates in video footage, transforming low-quality or standard-definition videos into ultra-sharp, high-resolution cinematic outputs up to 4k and 120FPS.

API Endpoint

Parameters

videorequired
string (uri)

Video to upscale in mp4

target_fpsoptional
integer

Target FPS (15fps to 120fps)

Default: 60Range: 15 - 120
target_resolutionoptional
string

Target Resolution

Default: "1080p"
Allowed values :
"720p""1080p""4k"

Response Type

Returns: Video

Asynchronous requests (v2)

Use Async for video, long-running (>~60s), or high-concurrency workloads; Sync is simplest for fast image & LLM calls. Async submits a request and you poll it to completion.

  1. 1
    POST /v2/topaz-video-upscale

    Submitreturns request_id, status_url, response_url

  2. 2
    GET /v2/requests/{id}/status

    Polluntil COMPLETED or FAILED

  3. 3
    GET /v2/requests/{id}

Status states

QUEUEDAccepted, waiting for a worker
PROCESSINGRunning on a worker
COMPLETEDDone — result body is ready
FAILEDErrored (incl. content/RAI blocks)
  • A FAILED request is served as HTTP 422 — the body still carries the error detail.
  • An unknown or expired request_id returns HTTP 404.
  • Results are retained for 1 hour, then expire.
  • Content / RAI blocks surface as FAILED, not a separate state.
  • Track completion by polling the status endpoint.
