<title>Riguardo i parameti di codifica e la qualità:</title>
<para>
Just because I recommend <option>mbd=2</option> here does not mean it
should not be used elsewhere. Along with <option>trell</option>,
<option>mbd=2</option> is one of the two
<systemitem class="library">libavcodec</systemitem> options that
increases quality the most, and you should always use at least those
two unless the drop in encoding speed is prohibitive (e.g. realtime
encoding). There are many other options to
<systemitem class="library">libavcodec</systemitem> that increase
encoding quality (and decrease encoding speed) but that is beyond
the scope of this document.
Il fatto che qui venga cosigliata <option>mbd=2</option> non significa che
non si debba usare altrimenti. Insieme con <option>trell</option>,
<option>mbd=2</option> è una delle due opzioni di
<systemitem class="library">libavcodec</systemitem> che ottimizzano al
meglio la qualità e sarebbero sempre da utilizzare entrambe a meno che
l'aumento della velocità di codifica sua proibitivo (ad es. per la codifica
in tempo reale (realtime)). Ci sono molte altre opzioni di
<systemitem class="library">libavcodec</systemitem> che aumentano la
qualità (e rallentano la codifica), ma questo non è l'obiettivo di
questa documentaziione.
