Frequently Asked Questions
- How accurate are AI-generated subtitles?
- AI produces highly accurate transcriptions for clear speech. The large-v3 model achieves near-human accuracy for English and many other languages. Accuracy depends on audio clarity — clean recordings with minimal background noise yield the best results. You can always edit the SRT file to fix any errors.
- What languages does the auto subtitle generator support?
- AI supports over 90 languages including English, Spanish, French, German, Portuguese, Chinese, Japanese, Korean, Hindi, Arabic, Russian, Turkish, and many more. Language auto-detection is available, or you can specify the language for better accuracy.
- Can I edit the generated subtitles?
- Yes. The tool exports a standard SRT file which you can open in any text editor or subtitle editor. Adjust timing, correct text, or change formatting before using the subtitles. You can also use our burn subtitles tool to permanently add the edited SRT to your video.
- What is the difference between SRT export and burned-in subtitles?
- SRT is a separate subtitle file that video players overlay on top of the video — viewers can toggle it on/off. Burned-in (hardcoded) subtitles are permanently rendered into the video pixels, so they show on every platform including social media where players may not support SRT files.
- Which AI model should I use?
- For quick results, use base or small — they're fast and work well for clear English audio. For maximum accuracy, especially with accents, background noise, or non-English languages, use large-v3. The large-v3-turbo model offers a good balance of speed and accuracy.
- Can I generate subtitles for a YouTube video?
- Yes. Download your YouTube video, upload it here, and the AI generates an SRT file you can upload to YouTube Studio. This is faster and often more accurate than YouTube's built-in auto-captions, especially for non-English content.
