Frequently Asked Questions
What is WebVTT (Web Video Text Tracks)?
WebVTT (Web Video Text Tracks) is the modern standard for displaying subtitles on the web, designed specifically for use with HTML5 video. It's similar to SRT but includes added features for styling (using CSS), positioning, and metadata. This allows for more dynamic, accessible, and richly formatted captions and subtitles directly in the browser.
How is VTT different from SRT?
The main differences are that VTT supports styling, positioning, and metadata, while SRT does not. VTT also has a slightly different timestamp format (using a period instead of a comma for milliseconds) and requires a 'WEBVTT' header. VTT is the standard for modern web video.
Can I use HTML tags in a VTT file?
You can use certain HTML-like tags within VTT cues for basic formatting, such as <b> for bold, <i> for italic, and <u> for underline. You can also define more complex styles in an external CSS file linked to the video player.
How accurate is the AI transcription?
Our AI transcription service provides highly accurate results, with precise timing and synchronization for VTT files. The system is trained on millions of hours of content to ensure professional-quality output.
Can I edit the subtitles after generation?
Yes, you can easily edit the generated VTT files using any compatible subtitle editor. The files are provided in standard format for maximum flexibility.
