Best AI video enhancement APIs in 2026

What to evaluate

• Quality — does it use modern models (Real-ESRGAN, GFPGAN) for real super-resolution and face restoration?
• Privacy — does it train on your uploads, sell data, or keep files indefinitely?
• Integration — submit-by-URL, webhooks, idempotency, a free sandbox?
• Pricing — predictable, usage-based, no surprises?

Where BetterVideo fits

BetterVideo is the privacy-first option: Real-ESRGAN + GFPGAN quality, a clean REST API with webhooks and a free sandbox, simple per-second pricing — and a guarantee most APIs won't make: never trained on, never sold, auto-deleted, with signed deletion certificates on the Secure tier. If footage sensitivity matters, that's the differentiator.

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":"1080p"}'

import requests
r = requests.post("https://api.bettervideo.io/v1/jobs",
    headers={"Authorization": "Bearer YOUR_KEY"},
    json={"video_url": "https://.../clip.mp4", "resolution": "1080p"})
job = r.json()  # poll GET /v1/jobs/{job['id']} until status == "done"

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: "1080p" })
});
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.
