Ifomathi yeCD yeVidiyo (nayo iyaziwa i-VCD) yenziwa ngo-1993, kwiminyaka embalwa ngaphambi kwevidiyo ye-DVD (esiyibiza ngokuba yiDVD). I-VCD ayizange ibanjwe ngendlela yokwenza i-DVD format, nangona kunjalo. Nangona zombini ifomathi idlala ividiyo, kukho ukungafani kobugcisa phakathi kwabo.
Ukuqwalasela ukuhluka
Yilungele, siza ku fumana i-nerdy elinelapha apha. Ividiyo yeDVD yedijithali icindezelwe isebenzisa i-MPEG-1 codec. Ividiyo ye -MPEG-1 ingadlaliswa emva kwayo nayiphi na umdlali weDVD okanye isofthiwe yokudlala i-DVD enokukwazi ukudibanisa ividiyo ye-MPEG-1. Ii-VCD zingathiwa malunga nomgangatho wevidiyo yeVHS, kwaye inokubamba malunga neyure enye yevidiyo yedijithali.
Ividiyo yeDVD yedijithali icindezelwe isebenzisa i-MPEG-2 codec. I-MPEG-2 ye-video compression ifana nevidiyo yevidiyo yeDVD kwaye inokudlala kuyo yonke i-DVD abadlali okanye i-DVD yokudlala. IiDVD ziyakwazi ukugcina iiyure ezimbini zevidiyo (okanye ngaphezulu, khangela i-article, ii- DVD Size, Yintoni i-DVD-5, iDVD-10, iDVD-9, iDVD-18 neDVD Layer DVDs ) ngolwazi olungaphezulu). Ngaphandle kokufumana ubuchwepheshe obuninzi, ukunyanzeliswa kwe-MPEG-2 kukugqithiswa kwezinga eliphezulu ngaphezu kwe-MPEG-1 kunye neziphumo kumgangatho ophezulu kakhulu wesithombe kwiiDVD kuneCD cV.
Umgca ophezulu kwiiDVD kunye neeVCD kukuba iiDVD zingabamba ubuncinci inani levidiyo yedijithali njengeVCDs, kunye nokurekhodwa kwekhwalithi ephezulu. Ii-VCD zikhulu xa ufuna ukwenza iikopi ezininzi zevidiyo ethile ukuze wabelane, kwaye umgangatho awukho umba. Ngokubanzi, uya kufuna ukunamathela kumaDVD kwiinkcukacha ezininzi zokurekhoda kwevidiyo.
Ngaba kufuneka usasebenzise iVCD?
Ngokuqhelekileyo, asisayikusebenzisa ifomathi yeVCD. Hayi kuphela ubude bevidiyo efutshane kwiVCD kunamanye amafomathi, isisombululo singaphantsi kwezinto esizijwayele ngazo zonke. Ngaphantsi ngaphantsi? Isisombululo esiphezulu siphepha ngaphezu kweepilikisi ze-2 million kanti i-VCD ingaphantsi kwama-pixels angama-85,000.
Ndiyabulela ngokukhawuleza kwintsebenziswano kunye nobuninzi beendawo zokwabelana nge-inthanethi (okt Youtube okanye iVimeo phakathi kwabanye), abantu abayitshisi iVCD okanye iDVD ngaphezulu. Kulula kakhulu ukwenza ividiyo yakho kwaye uyilayishe kwisiza sokwabelana.
