Common Questions

Everything you need to know about
automated subtitles

How do automated subtitles work?

Upload your video to Sonix and our AI automatically transcribes the audio with word-level timestamps. The transcription is formatted into subtitles with proper timing. Edit if needed, then export in your preferred format—SRT, VTT, or others.

What subtitle formats does Sonix support?

Sonix exports subtitles in SRT (SubRip), VTT (WebVTT), SCC (Scenarist), TTML, STL, DFXP, CAP, and more. We also support professional video editor formats—FCPXML for Final Cut Pro, XML for Adobe Premiere Pro, EDL for AVID Media Composer, and compatible formats for DaVinci Resolve.

How accurate are automated subtitles?

Sonix delivers 99% accuracy on clear audio—comparable to professional human transcription. Audio quality, background noise, and accents can affect accuracy. Our editor makes corrections quick and easy.

Can I add subtitles directly to my video?

Yes. Sonix's burn-in feature permanently embeds subtitles into your video file. Customize fonts, colors, size, and position. Download a video file with hardcoded captions ready to share anywhere.

How do I add subtitles to YouTube videos?

Export your subtitles as SRT or VTT, then upload them to YouTube Studio. YouTube accepts both formats. You can also use auto-sync if your timing needs adjustment. Sonix's timing is usually precise enough for direct upload.

Can I edit the subtitles before exporting?

Absolutely. Sonix includes a powerful online editor for reviewing and correcting subtitles. Edit text, adjust timing, split or merge subtitle blocks, and preview your changes before export.
