Frequently Asked Questions

What is OCR subtitle recognition?

OCR (Optical Character Recognition) subtitle recognition uses AI to detect and read text directly from video frames, converting visual text into editable subtitle files.

How does it handle multiple languages?

Our OCR system can automatically detect and recognize multiple languages in the same video. For mixed language content (like English on top, Chinese below), it can process each region separately.

What languages are supported?

We support English, Chinese (Simplified and Traditional), Japanese, Korean, and automatic language detection for mixed content.

How accurate is OCR recognition?

Accuracy depends on video quality and text clarity. High-quality videos with clear text typically achieve 70-90% accuracy. You can adjust the confidence threshold to filter results.

Can it handle videos with both English and Chinese subtitles?

Yes! Our system can detect and process mixed language content. It can recognize English text in the upper portion and Chinese text in the lower portion of the video frame.

How long does OCR processing take?

Processing time depends on video length and frame rate. A 1-minute video typically takes 2-5 minutes to process. Longer videos will take proportionally more time.
