Iikhamera zedijithali ziguqula imifanekiso ehambayo kwi data yedijithali. Le datha yevidiyo, ebizwa ngokuba yiibits , igcinwa kwimidiya yokugcina njengememori khadi, iDVD, okanye i- disk drive .
Isixa solwazi esibhalwe phantsi nawuphi na wesibini obizwa ngokuba yi- bit rate okanye i- bitrate , kunye neenkcorder, kulinganiswa kwimigabits (isigidi esisodwa) kwisibini (Mbps).
Kutheni Ufanele Uzinakekele?
Ukulawula umlinganiselo wenkcitho kungekhona nje kuphela ocacisa umgangatho wevidiyo orekhodayo, kodwa nokuba uza kuba nexesha elingakanani ukurekhoda ngaphambi kokuphuma kwimemori. Nangona kunjalo, kukho urhwebo-off-quality / high-bit rate rate ithetha ixesha elifutshane lokurekhoda.
Unokukhetha okubaluleke kakhulu ixesha lokurekhoda okanye ikhwalithi yevidiyo-ngokulawula isantya se-camcorder. Oku kwenziwa ngeendlela zokurekhoda zekhamera. Ezi modes zibizwa ngokuba ngumgangatho ophezulu, umgangatho, kunye nerekhodi ende .
Imodi yekhwalithi ephakamileyo inomlinganiselo omncinci kakhulu, ukufumana inani elikhulu lemali. Iimodeli ezide zerekhodi ziya kuba neerhafu eziphantsi, ukunciphisa inani leedatha ukululalisa amaxesha okurekhoda.
Ngayiphi i-Bit Bit Matter?
Njengomgaqo jikelele, akudingeki ukuba uqaphele umlinganiselo wenkcitho yakho ngelixa usebenzisa i-camcorder. Khangela nje imo yokurekhoda ehambelana neemfuno zakho kwaye zonke zihleliwe. Xa kuthengwa i-camcorder, nangona kunjalo, ixabiso lokuqonda lingafumaneka ngokufanelekileyo, ngokukodwa xa uvavanya i -camcorders ephezulu-definition .
Iikhompyutha ezininzi ze-HD zizenzele ngokwazo njenge "HD epheleleyo" kwaye zenze i-1920x1080 yokurhumela isisombululo. Nangona kunjalo, akubona zonke ii-camcorders ezipheleleyo ze-HD ezirekhodiweyo kwi-bitrate ephezulu.
Cinga i-Camcorder A ne-Camcorder B. I-Camcorder Iirekhodi ze-1920x1080 ividiyo kwi-15 Mbps. I-Camcorder B irekhoda i-1920x1080 ividiyo kwi-24 Mbps. Bobabini banesisombululo esifanayo sevidiyo, kodwa i-Camcorder B inezinga eliphezulu lokuhamba. Zonke izinto zilingana, i-Camcorder B izakuvelisa ividiyo ephezulu.
Ukulinganisa iMemori
Isantya esincinci sinokubaluleka ukuba unayo i-memory card-based based camcorder. Amakhadi eememori anenani lawo lokutshintshwa kwedatha, elilinganiselwe kwi-megabytes ngesibini okanye i-MBps (1 megabyte = i-megabits 8).
Ezinye iimemori zeememori ziphuza kakhulu kwiikhampasi zezinga eliphezulu, kwaye ezinye zikhawuleza. Baya kubhala kwakhona, kodwa uya kuhlawula ngokukhawuleza ngekhawuleza awunayo.
Ngaba Uya kubona Ubomi?
Ewe, uya kubona umdahluko, ngokukodwa kwimida ekude yebala, phakathi kwezinga elona liphezulu kunye neyona ephantsi. Kwimeko ephantsi kweyona mgangatho, unokubona ubuninzi be-digital artifacts, okanye ukuphazamiseka, kwividiyo. Njengoko uhamba ukusuka kwinqanaba elilodwa ukuya kwelinye elilandelayo, utshintsho lubuqili.
Yiyiphi Imilinganiselo Okufuneka Ubhalise Ngayo?
Qinisekisa kwizinga elona nani liphezulu kunye nesimo sokumgangatho onokukwenza, xa unememori eyaneleyo. Unokuhlala uthabatha ifayile yevidiyo ephakamileyo (oko kukuthi, ifayile enkulu yedatha) kwaye uyayinciphisa nge software software. Nangona kunjalo, ukuthatha iifayile ezisezantsi kunye nokuphucula umgangatho walo ngokungongeza idatha engenakwenzeka.
