Convert SDR to HDR Online — No Software to Install

Why this matters

Local SDR-to-HDR tools need a modern GPU, specific drivers, and a working FFmpeg. For a single clip that setup cost dwarfs the conversion time.

An online API moves the heavy lifting to a GPU cluster. Upload or reference a URL, and the job runs while you do something else.

How it works

The web app wraps the same API used by studios: you provide a file or URL, choose cinema/documentary/sports, and download the HDR10 output.

Submit a job with an input URL (S3, GCS or HTTPS), poll the job URL, and download the rendered output. No GPU, no queues, no ffmpeg builds to babysit.

Code

import requests, time

API = "https://api.mlslabs.io/v1/sdr2hdr/jobs"
headers = {"X-API-Key": "YOUR_API_KEY"}
payload = {"input": "https://cdn.example.com/clip.mp4", "preset": "cinema"}

resp = requests.post(API, json=payload, headers=headers)
job = resp.json()
while job["status"] not in ("succeeded", "failed"):
    time.sleep(3)
    job = requests.get(job["url"], headers=headers).json()

print("Output:", job["output_url"])

Pro tips

• Use the free tier for one-off clips; metered pricing applies beyond it.
• HTTPS URLs work directly — no upload needed if the file is already hosted.
• Check the output on an HDR screen or with an HDR waveform, not a phone in daylight.

Open the SDR2HDR collection — the same job the web app runs.
