Czy warto enkodować w XviD'zie (vs. DivX 5.0 Pro) ? , pachura 17/01/03 21:43
Cześć,
Mam jakiśtam materiał video który chcę puścić w świat... ostatnio obserwuję że dużo filmów encoduje się codekiem XviD a nie standardowym DivX'em. Czy rzeczywiście ma on jakieś lepsze osiągi (szybsza kompresja, mniej obciążająca procesor dekompresja, może lepszy stosunek rozmiar pliku/jakość?).
Czy nie jest to tylko bunt młodych fanów idei opensource wobec wprowadzenia opłat za wersję Pro codeka DivX?
Dzięki!- Eeeee tam... , DJopek 17/01/03 21:47
Koduj nawet w divx 3.11 obyś tylko kodował poprawnie, tzn. ustawił odpowiednią rozdzielczość, bitrate, odpowiedni dźwięk do tego i parę innych rzeczy... Mnie aż trafia jak większość produkcji kodowana jest tak że pożal się boże...- bardzo dobrze piszesz! , Tummi 17/01/03 22:32
Mnie najbardziej wkurza, jak widze, ze ktos nie przycial dokladnie filmu i zostaly 2-pixelowe paski po bokach/na gorze/na dole - ile bitratu na to idzie!
Co do XviDa - jest dokladnie tak, jak mowisz - nie w porzadku jest to, ze z darmowego projektu (divx 3.11) open source zrobilo sie cos, za co trzeba placic. A XviD jest open-source, mozna zawsze napisac do tworcy (Koepi i inni), albo samemu naprawic buga i wypuscic swoja kompilacje ;-))))
Information wants to be free ;-)))))))
T.www.skocz.pl/uptime :D - Piszesz bzdury, Tummi. , pachura 17/01/03 23:02
Piszesz bzdury, Tummi. Divx 3.11 był spiraconą wersją codeka Microsoftu - był nielegalny i to dopiero było nie w porządku.
Za DivX-a nikt Ci nie każe płacić - wersja 5.0 standard jest kompletnie za darmo, pozwala odtwarzać wszystkie DivX-y stworzone do tej pory (również te w wersji Pro) i encodować z jakością DivX 4.1.2.
Co mi po tym że XviD jest opensource skoro jest gorszy?- jestes pewien? , Tummi 18/01/03 01:43
spiracony? no cos TY!? NAPRAWDE????? ;>>>>>>>>
To nie zmienia faktu, ze byl open-source ;-) Jak ktos chial, to mogl sobie skompilowac w domciu ;-)))))
DivX 5 jest darmowy, tak? To sciagnij sobie kodeki ze strony divx'a, poczytaj umowe i powiedz mi, co maja biedne firmy zrobic?
Odrebna kwestia to podejscie BSA do tego kodeka jako calosci ;-)))
Co do tego, ze XviD jest gorszy - mozesz mi przedstawic suche fakty? Jak narazie widze, ze Koepi dwoi sie i troi nad swoimi bulidami, a divxnetworks cieplym moczem wszystko traktuje...
T.www.skocz.pl/uptime :D
- Bum srata tata , pachura 17/01/03 22:10
Encodowałem w DivX-ie 3.11, 4.0.2 i 5.0 Pro. Wiem jak to się robi, pytam tylko o to czy XviD ma jakąś przewagę nad tym ostatnim. Prawdopodobnie oleję XviD-a bo nie wszyscy mają do niego codeki. - nie ma , zylka 17/01/03 22:18
żadnej przewagi a nawet jest słabszy niż Divx 5.0 ale jest za free a pozatym jest to pewnien rodzaj znobizmu w śród grup rippujących. Ja radził bym ci Divx 5.0 lub SBC - enkoduj dobrze , tebe 17/01/03 23:34
tzn. enkoduj dwu-przebiegowo
a czy Xvid jest lepszy ? moze juz jest a moze dopiero bedzie, w koncu jest wciaz rozwijany.
kiedys byly testy porownujace rozne kodeki na www.divx.pl, moze znajdziesz tam cos o Xvid, ale z tego co ja pamietam to DivX 5 miał byc bardziej obciazajacym CPU.
A dlaczego grupy wypuszczaja ripy zakodowane w ten a nie inny sposob ? Bo maja swoj regulamin, jesli chcesz wejsc do ich swiatka to musisz ich przestrzegac.
