Video Super-Resolution API (Real-ESRGAN)

Run Real-ESRGAN video super-resolution without hosting a GPU. POST a video URL and BetterVideo increases resolution and reconstructs detail frame-by-frame, then hands back the enhanced result.

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

Real-ESRGAN, as a hosted endpoint

Real-ESRGAN (x2plus) is excellent but heavy to host and run at scale. BetterVideo runs it for you on L4/L40S GPUs, batches frames in parallel, reassembles the video, and returns a download link — you just call the API.

Super-resolution + face restoration together

Super-resolution alone can leave faces soft. BetterVideo pairs Real-ESRGAN with GFPGAN so faces stay sharp and natural — a combination that's tedious to wire up yourself.

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.

Frequently Asked Questions

Real-ESRGAN x2plus for super-resolution, paired with GFPGAN v1.4 for face restoration.

You can run Real-ESRGAN yourself, but you'd manage GPUs, batching, and privacy. The API removes all of that.
