https://api.segmind.com/v1/kandinsky-6-vsrParameters
videorequiredstring (uri)Video to upscale. Up to 121 frames at 24 fps (about 5 seconds); longer clips are rejected, so trim first.
modeoptionalstringpro restores the most detail (5 steps by default). lite is faster and about 16% cheaper (2 steps by default).
"pro""pro""lite"num_inference_stepsoptionalintegerDenoising steps per tile. Leave empty for the mode's default (pro 5, lite 2). More steps add detail and cost (about +5% per step).
seedoptionalintegerRandom seed for reproducible results. -1 picks one at random.
-1Range: -1 - 999999999999999upscale_factoroptionalnumberTotal upscale applied to the input resolution. 2.25 takes 480p to 1080p and accepts any size; 2 and 4 need the video's width and height to be multiples of 16.

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
POST /v2/kandinsky-6-vsrSubmit — returns request_id, status_url, response_url
- 2
GET /v2/requests/{id}/statusPoll — until COMPLETED or FAILED
- 3
GET /v2/requests/{id}Result — final response body
Status states
- 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.
