FAQs

Everything you need to know about AI subtitle generation

What are subtitles and why do I need them?
Subtitles are text overlays that display spoken dialogue in a video. They improve accessibility for deaf/hard-of-hearing viewers, boost engagement on social media (85% of videos are watched muted), and help non-native speakers understand your content.
How accurate is the AI subtitle generation?
Our AI achieves 98% accuracy across 20+ languages. It uses advanced speech recognition with word-level timing, automatic punctuation, and speaker detection. You can always edit any generated subtitle for perfection.
How do I add subtitles to my video?
Simply upload your video, click "Generate Subtitles," choose your language, and our AI does the rest in seconds. You can then customize styles, translate to other languages, and export with burned-in or separate subtitle files.
Can I extract subtitles from an existing video?
Yes. Upload any video and our AI will transcribe the audio into subtitle text. You can export as SRT, VTT, ASS, or plain text formats for use in any video editor.
How do I embed subtitles permanently into my video?
After generating and styling your subtitles, choose "Burn-in" export option. This permanently renders the subtitles onto your video frames, ensuring they display on any player without needing a separate subtitle file.
What video formats are supported?
We support MP4, MOV, AVI, MKV, WebM, FLV, and most common video formats.
