Koliko vam traje kompletno kompresovanje DVD (4.7GB) u DviX (700MB)?

Pa sad nisam siguran da li je mnogo, to je manje-više realna vrednost za Celeron 2.66, mada možda je moglo sve to da završi i za 1 sat manje.

Koliko tačno traje taj film, mora da ima bar 2 sata kad je toliko dugo kompresovao?

Zavisi od podešavanja u xvid-u.Verovatno je nešto podešeno za bolji kvalitet zarad utrošenog vremena.

Evo ovako DVD koji sam ripovao je lošeg kvaliteta, nešto kao snimak sa kasete, možda je to jedan od razloga da je ceo proces trajao tako dugo, a i nisam dirao podešavanja XviD-a.

S obzirom da si film radio u dva prelaza i da ti je procesor Celleron to je za ocekivati. Zavisi duzina kompresije i od jos nekih parametara ali dva koja si naveo navise uticu na duzinu trajanja enkodovanja...

AutoGK 2.25, XviD 1.0.3, Harry Potter 3 za 05:03. Sada brže skoro 30 minuta ista podešavanja, originalni DVD.

Athlon 64 3000+ venice na 1800Gh (još nije klokovan), 1Gb rama AutoGK čini mi se 2.4 (pišem iz Viste a to mi je sve na XP-u), Xvid kompresija, bez subtitla, audio po postavkama.

Obrada traje u proseku oko 3 i po sata (uradila nekoliko DVD-a), snimci skoro savršeni.

Veoma sam zadovoljna autoGK programom i neću ga menjati.

Kompjuter:
Athlon 2500+ sa 512 MB rama (single channel 200 mhz)

ulazni fajl:
.VOB fajl od 4,12 GB dobijen DVD decrypterom
rezolucija 720x576
trajanje filma 87 minuta

program:
VirtualDubMod

kompresija:
DivX 6.4 codec - balanced (default) encoding mod
video bitrate= 980 kbps
izlazna rezolucija 512x384

dobijeni fajl velicine:
681 MB (zajedno sa zvukom MP3 na 96 kbps)

kompresija u dva prolaza trajala skoro 6 sati.
sa pripremom, dekriptovanjem, konvertovanjem audia itd trajalo oko 6 sati i 20 minuta.
i u prvom i drugom prolazu kompresija se vrsila oko 10 do 13 fps


***kod mene trajanje kompresije dosta zavisi od rezolucije koju trazim. veca rezolucija duze traje iako je bitrate isti.
Ako u podesavanjima divx kodeka izaberem Better Quality onda kompresija traje do 30% duže ali postiže malo bolji kvalitet slike.

radi usporedbe...

kompjuter 2:
DELL Dimension C521
intel procesor na oko 2 ghz
oko 480 MB rama

Pri video kompresiji sa istim parametrima kao u prethodnom primeru obavlja posao oko 30% brže.
u svakodnevnom koriscenju je daleko neprijatniji za rad od prethodno pomenutog athlona. sve se dugo ucitava i preterano radi sa hard diskom... ocigledno da ga guši nedostatak ram memorije ali to za divx kompresiju izgleda nije bitno.
