VOB in sintesi
VOB
Convert to VOB when preserving DVD-video structure, maintaining authored disc compatibility, or recovering content from DVD-based collections.
It is useful for archival and disc-focused workflows where the DVD container family still matters.
For file-based viewing and sharing, MP4 is usually the better target.
AC3 in sintesi
AC3
Convert to AC3 when the output is intended for surround-capable consumer playback, especially DVD, broadcast, legacy streaming hardware, or home-theater distribution.
It is a strong target for 5.1-compatible delivery where broad device support matters more than lossless fidelity.
For mastering or archival preservation, lossless formats are usually better.
