# Hard-Subtitle OCR

> Pull burned-in on-screen captions from the Learn panel with OCR, without speech-to-text. Best for interviews and courses (Beta).

## Overview

Some interviews and courses already have captions burned into the picture. Open Hard-subtitle OCR (Beta) in the Learn panel, pick the caption language, and tap Start. You get a timestamped list without running speech-to-text.

## Pain Point

The picture already has clear captions, but speech-to-text trips on accents and background noise. I want the words that are already on screen.

## Key Features

* Hard-subtitle OCR (Beta) tab at the top of the Learn panel
* Chinese, English, Japanese, French, German, and Spanish
* Timestamped caption list on the right after recognition, for review and seeking
* Reads on-screen text only; no speech required

## Highlights

When captions are already in the frame, reading them is faster and steadier than listening.

## Use Cases

* Interviews and courses with a clean lower-third caption area
* Heavy accents or noisy rooms where speech-to-text fails
* Quick checks of on-screen wording against timestamps

## Tips

* Extra text near the captions lowers accuracy. Stylized or title-heavy videos do worse
* This is still Beta. If results are messy, fall back to speech-to-text or a cleaner source
