- No styling beyond basic HTML — no positioning, no colors beyond italic/bold.
- Character encoding ambiguity — some SRTs are Windows-1252, some UTF-8, some UTF-16.
- Cannot represent multiple speakers, sound effects, or precise positioning like SSA/ASS can.
VTT Limitaciones
- Slightly more verbose than SRT.
- Tooling in desktop players lags behind SRT.
- Browser CSS styling of cues varies in subtle ways.

Yes, to a high degree. Standard fonts, headings, lists, tables, images, hyperlinks and page structure transfer cleanly. Custom fonts substitute to the closest match if not embedded; obscure layout features unique to SRT (frames, legacy macros) may flatten to static content in the target format.
