Informazioni sui file EPUBConfronto dei punti di forza
ASS Punti di forza

- Precise timing (millisecond) with advanced animation effects.
- Multi-font, multi-layer, gradient, rotation, 3D transform.
- Mature tooling via Aegisub.
- Supported by VLC, mpv, MPC, and every major desktop player.
EPUB Punti di forza

- Reflowable text — adapts to any screen size, font size, or orientation.
- Rich typography via CSS, embedded fonts, and SVG.
- Accessibility-first: native support for screen readers, adjustable text, and alt-text.

Limitazioni
ASS Limitazioni
- No formal standard — conventions only.
- Web video (HTML5 <video>) cannot render ASS natively.
- Complex effects require manual authoring — no WYSIWYG in most tools.
- Steep learning curve compared to SRT.
EPUB Limitazioni
- Kindle does not support EPUB natively (Amazon wants you to convert to AZW3).
- Fixed-layout EPUBs (for children's books, comics) are awkward to author.
- Rendering quality varies between apps — some CSS works everywhere, some does not.
- Adobe DRM (ADEPT) or Apple FairPlay are optional layers that complicate portability.

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 ASS (frames, legacy macros) may flatten to static content in the target format.
