WebVTT (Web Video Text Tracks) is a modern subtitle format designed for web video players. It supports advanced features like styling, positioning, and metadata.

The paragraphs below describe what you can expect when converting your subtitles to WebVTT.
SubRip (SRT) is the most common subtitle format. Converting SRT to WebVTT is straightforward as both formats share similar basic structure. The main difference is that WebVTT files start with a "WEBVTT" header and use slightly different timestamp formatting. All timing and text content will be preserved during conversion.
Advanced Substation Alpha (ASS) and Substation Alpha (SSA) formats support many advanced features like custom fonts, colors, positioning, and effects. While WebVTT supports some styling capabilities, many advanced ASS/SSA features will be simplified or removed during conversion. Basic text content and timing will be preserved, but complex animations and positioning may be lost.
