NovaScribe generates subtitle files (SRT and VTT) automatically from audio or video using AI transcription. Upload a file and download subtitles in minutes. Plans start at $2/month with a 30-minute free trial.
What Are SRT and VTT Subtitle Files?
Subtitles are text overlays that display spoken dialogue synchronized to video playback. They make content accessible to deaf and hard-of-hearing viewers, improve engagement on social media (where most videos play muted), and help viewers follow along in noisy environments.
SRT (SubRip) is the most widely used subtitle format. It works with YouTube, Vimeo, TikTok, LinkedIn, Premiere Pro, DaVinci Resolve, Final Cut Pro, and virtually every video platform and editor.
VTT (WebVTT) is the web-native format designed for HTML5 video players. It supports additional styling options like font color and positioning. YouTube and most modern platforms accept both formats.

Subtitle Generator FAQ
How do I generate subtitles from audio?
Upload your audio or video file to NovaScribe using drag-and-drop or the file browser. Our AI transcription engine processes the file, detects spoken words with precise timestamps, and generates a subtitle file. Once complete, export as SRT or VTT format — both are compatible with YouTube, TikTok, LinkedIn, and most video editors. The entire process takes a few minutes for most files.
What subtitle formats does NovaScribe support?
NovaScribe exports subtitles in SRT (SubRip) and VTT (WebVTT) formats. SRT is the most widely supported format and works with YouTube, Premiere Pro, DaVinci Resolve, Final Cut Pro, and most social media platforms. VTT is the web-native format used by HTML5 video players and is also accepted by YouTube and other platforms.
How accurate are AI-generated subtitles?
Accuracy depends on audio quality, background noise, and speaker clarity. For clear recordings with minimal background noise, NovaScribe typically delivers high accuracy suitable for professional use. You can review and edit subtitles in the built-in editor before exporting. For content with heavy accents or technical jargon, a quick review pass is recommended.
Can I generate subtitles in different languages?
Yes, NovaScribe generates subtitles in 99 languages including English, Spanish, French, German, Portuguese, Italian, Chinese, Japanese, Korean, Arabic, Hindi, and many more. The language is detected automatically from the audio, or you can specify it manually for best results.
What is the difference between SRT and VTT subtitle files?
SRT (SubRip) is the most widely used subtitle format — simple, universal, and accepted by virtually every video platform and editor. VTT (WebVTT) is the newer web-native format that supports additional styling like font color and positioning. For most use cases, SRT is the safer choice. Choose VTT if you need web playback or custom styling.
Can I edit subtitles before downloading?
Yes. After transcription, you can review and edit the full transcript in NovaScribe's built-in editor. Fix any words, adjust timing, rename speakers, and then export the corrected version as SRT or VTT. This gives you professional-quality subtitles without manual timing work.
What video and audio formats can I upload?
NovaScribe accepts all common audio formats (MP3, WAV, M4A, FLAC, OGG, AAC) and video formats (MP4, MOV, AVI, MKV, WebM). For video files, we extract the audio track automatically. Files up to 100MB are supported.
How much does subtitle generation cost?
Subtitle generation uses the same pricing as transcription. The free trial includes 30 minutes. Paid plans start at $2/month for 200 minutes (Starter), $5/month for 1,000 minutes (Basic), $10/month for 2,500 minutes (Pro), and $20/month for 6,000 minutes (Studio). A 1-hour video costs approximately $0.30 to subtitle on the Basic plan.
Note: NovaScribe generates subtitles using AI speech recognition. Accuracy may vary based on audio quality, accents, and background noise. We recommend reviewing subtitles before publishing.
