I-CD yedokhumenti yevidyo (futhi iyazi i-VCD) yadalwa ngo-1993, eminyakeni embalwa ngaphambi kwe-DVD-video (lokho esikushayela manje i-DVD). I-VCD ayitholanga ngempela indlela ama-DVD enza ngayo, noma kunjalo. Naphezu kokubili amafomethi adlala ngevidiyo, kukhona ukungafani kobuchwepheshe phakathi kwabo.
Ukuhlola ukuhluka
Yilungele, sizokuthola i-nerdy littler lapha. Ividiyo ye-VCD yedijithali icindezelwe usebenzisa i-codec ye-MPEG-1. Ividiyo ye-MPEG-1 ingadlaliswa emuva kunoma iyiphi i-DVD player noma isofthiwe yokudlala i-DVD ekwazi ukuxilisa ividiyo ye-MPEG-1. Ama-VCD angathiwa ngekhwalithi yevidiyo yeVHS, futhi angabamba cishe ihora elilodwa levidiyo ye-digital.
Ividiyo ye-digital digital icindezelwe usebenzisa i-MPEG-2 codec. Ukucindezelwa kwevidiyo ye-MPEG-2 kufaniswa nevidiyo yekhwalithi yeDVD futhi ingadlalwa kuzo zonke abadlali beDVD noma isofthiwe yokudlala i-DVD. Ama-DVD angabamba amahora amabili wevidiyo yedijithali (noma ngaphezulu, bheka isihloko, ama- DVD Usayizi, Kuyini i-DVD-5, DVD-10, DVD-9, DVD-18 neDVD Layer DVDs? Ngaphandle kokuthola ubuchwepheshe obukhulu, ukucindezelwa kwe-MPEG-2 kungukucindezelwa kwekhwalithi ephezulu kune-MPEG-1 kanye nemiphumela ekhwalithi ephezulu yesithombe yamaDVD kunamavidiyo wevidiyo.
Okubalulekile kuma-DVDs vs. VCDs ukuthi ama-DVD angabamba okungenani kabili inani levidiyo yedijithali njenge-VCDs, futhi lirekhodi eliphakeme leqophelo. Ama-VCD amnandi uma ufuna ukwenza amakhophi amaningi evidiyo ethile ongayabelana ngayo, futhi ikhwalithi ayiyona inkinga. Ngokubanzi, uzofuna ukunamathela kuma-DVD wokuqopha okuningi kwevidiyo yakho.
Ingabe Kufanele Usasebenzise VCD?
Ngokuvamile, akusadingeki ukusebenzisa ifomethi ye-VCD. Akuyona nje ubude bevidiyo emfishane ku-VCD kunamanye amafomethi, isinqumo singaphansi kwalokho esikujwayele sonke. Kude kangakanani ngaphasi? Isinqumo se-High-definition singaphezu kwamaphikseli angaphezu kwezigidi ezimbili kanti i-VCD ingaphansi kwama-pixel angu-85,000.
Ngenxa yokusheshisa okusheshayo nokuxhumeka kwamasayithi okwabelana nge-intanethi (okungukuthi i- Youtube noma i- Vimeo phakathi kwabanye), abantu abashise ama-VCD noma i-DVD. Kulula kakhulu ukwenza ividiyo yakho futhi uyilayishe kusayithi lokuhlanganyela.
