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 -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.
