Informazioni sui file SUBConfronto dei punti di forza
DOCX Punti di forza
- Much smaller than the legacy .doc format thanks to ZIP compression.
- Human-readable XML inside — automated extraction and manipulation is straightforward.
- Preserves formatting, images, tables, footnotes, comments, and track changes.
- Supported natively by Word, LibreOffice, Pages, Google Docs, and most modern editors.
- ISO/IEC 29500 standardized — not locked to a single vendor.
SUB Punti di forza
- VobSub preserves DVD subtitle appearance exactly.
- MicroDVD is trivially editable text.
- Universal player support (VLC, mpv, MPC).
- Historical format for DVD-era subtitle preservation.
Limitazioni
DOCX Limitazioni
- Subtle formatting drifts when opened in non-Microsoft editors (fonts, line spacing, tab stops).
- Macros and embedded scripts make older .docm variants a common malware vector.
- Complex layouts with floating objects often reflow unpredictably.
- Version compatibility matters — Word 2007 cannot open some Word 2019 features cleanly.
SUB Limitazioni
- Bitmap subtitles (VobSub) cannot be edited as text.
- MicroDVD frame-based timing breaks on framerate changes.
- Two incompatible formats sharing one extension causes confusion.
- Superseded by SRT and ASS for editing and modern streaming.
