Convert Video to SRT

Why this matters

SRT is the lingua franca of subtitles — every platform, editor, and translation vendor accepts it. Getting video into SRT is the recurring first step of localization.

For soft-subtitle sources, embedded tracks extract losslessly; for hardcoded sources, OCR does the job.

How it works

Pass the video URL; the API detects the best path (embedded track or OCR) and returns SRT, VTT, or ASS.

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/subtitle-extractor/jobs"
headers = {"X-API-Key": "YOUR_API_KEY"}
payload = {"input": "s3://bucket/video.mp4", "output_format": "srt"}

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

• Set output_format=srt unless you need styling (ASS) or web captions (VTT).
• For embedded tracks, extraction is instant and lossless.
• Re-run OCR on a cleaned master if accuracy is critical.
