Existují filtry pro předzpracování (pre-kompilace), používané k vstupním datům před zahájením kódování, filtry pro postprocesing, které se vztahují k výstupním datům po dokončení dekódování, stejně jako in-loop filtry a loop filtry, integrované v procesu kódování. Filtry pre-zpracování a post-zpracování jsou obvykle nenormativní a nebudou zahrnuté do kodeku (jsou externí do kodeku). Loop filtry jsou normativní. Je to součást kodeku. Používají se v procesu optimalizace kódování a aplikují se na uložené referenční rámce nebo pro inter-frame kódování. </p><p>AV1 používá tři normativní korekční filtry.   </p> <div class="mw-heading mw-heading3"><h3 id="Deblocking_filtr">Deblocking filtr</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=AV1&veaction=edit&section=2" title="Editace sekce: Deblocking filtr" class="mw-editsection-visualeditor"><span>editovat</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=AV1&action=edit&section=2" title="Editovat zdrojový kód sekce Deblocking filtr"><span>editovat zdroj</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Tento filtr je pro odstranění zřejmých artefaktů na okrajích kódovaných bloků.
