Video Upscaling API — upscale to 4K in one call

Upscale video to 1080p or 4K programmatically. POST a video URL with "resolution":"4k", BetterVideo upscales it on GPU with Real-ESRGAN, and you download a sharper, higher-resolution result.

Free sandbox key, no card. Never trained on. Never sold. Auto-deleted.

1080p or 4K from a single parameter

Set resolution to 1080p or 4k on the job. Real-ESRGAN (x2) handles super-resolution; GFPGAN restores faces; adaptive CLAHE and unsharp masking add clarity — all in one pass.

Why an API instead of a desktop tool

Desktop upscalers don't scale to a product. With an API you upscale on demand, in your own backend, with no install and no per-seat license — and your users' footage stays private (never trained on, auto-deleted).

One API call — curl, Python & Node

Submit a video by URL, then poll GET /v1/jobs/{id} until done (or receive a signed webhook), and fetch a time-limited download link:

cURL
curl -X POST https://api.bettervideo.io/v1/jobs \
  -H "Authorization: Bearer YOUR_KEY" -H "Content-Type: application/json" \
  -d '{"video_url":"https://.../clip.mp4","resolution":"4k"}'
Python
import requests
r = requests.post("https://api.bettervideo.io/v1/jobs",
    headers={"Authorization": "Bearer YOUR_KEY"},
    json={"video_url": "https://.../clip.mp4", "resolution": "4k"})
job = r.json()  # poll GET /v1/jobs/{job['id']} until status == "done"
Node.js
const res = await fetch("https://api.bettervideo.io/v1/jobs", {
  method: "POST",
  headers: { "Authorization": "Bearer YOUR_KEY", "Content-Type": "application/json" },
  body: JSON.stringify({ video_url: "https://.../clip.mp4", resolution: "4k" })
});
const job = await res.json();

Privacy is the default, not an upgrade

  • Never trained on. Pre-trained, fixed-weight models — your frames are enhanced and returned, never used to train AI.
  • Never sold or shared. No third parties, no data brokers, no "anonymized" resale.
  • Auto-deleted. Files self-delete (default 30 days), or delete any job instantly with one call.
  • Proof on the Secure tier. Every deletion can return a signed deletion certificate, with a full audit log.
