Real-world quality depends on three factors: source file quality, format capabilities, and encoder settings. Xonvert optimizes the third factor automatically, but starting with the best possible SRT Subtitle source always yields the best AsciiDoc Document output.

Subtitle files typically contain movie subtitles, while Document files are used for O'Reilly books. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.
