Cel mai bun grup de RAW-uri?


Cei mai mulți cunosc grupurile Leopard-Raws, Ohys-Raws și eventual Anime Land. Totuși cum știm ce alegem?

Bun, avem 3 participanți: Leo, Ohys și Land.

Mai întâi începem cu Leo, setări folosite la encode:

Singurele chestii deranjate mi se par a fi acel crf cam mare și aq-mode-ul care este setat la 1. Vizual, episodul se prezintă binișor, deși tind să cred că s-a folosit un preset slow sau medium. Zic asta pentru că în zonele complexe își face apariția blocking-ul.

Filtrare? Nu pare să se fi filtrat.


Dacă vă uitați în zona cerului, se poate observa banding-ul și o tentă de blocking.

Notă: 7.

Acum, trecem la Ohys. Setările folosite la encode:

Nu e bine deloc... setările sunt aproximativ cele care vin ”la pachet” cu preset-ul medium, exact așa cum au fost gândite de dezvoltatorii x264. Cam totul este deranjant la encode-ul celor de la Ohys. De la crf până la rc_lookahead. Pentru animații trebuie un rc_lookahead cam până-n 60. Personal, recomand 48, 54 și 60. Nu am să explic acum de ce, va exista un articol special pentru această setare.

Vizual, episodul se prezintă... la fel ca la Leopard. Banding și o tentativă de blocking


Notă: 5, cu indulgență.

Rândul celor de la Anime Land, setările de encode:

Eh, ăsta da encode. Hi444PP, 10-bit, setări ca lumea de encode. Nimic de reproșat.

Vizual, episodul se prezintă cu o lipsă de filtrare.


Nota: 8

Recomandare: 

Mereu căutați transport stream-uri pentru a vă face propriile RAW-uri, nu vă băzați mereu pe cele din străinătate pentru că nu sunt cea mai bună alegere. Nu întotdeauna.

Presupun că articolul este destul de clar și e de la sine înțeles că cele mai bune grupuri sunt Leopard și Anime Land. Pentru data viitoare, voi compara două grupuri românești de fansubbing și voi alege cea mai bună traducere, verificare, cel mai bun typeset, encode, ș.a.m.d.
