Qala Ukudubula iVidiyo enkulu yeHD ngeeNtshumo eziKhuselweyo
Iikhamera ze-DSLR kunye nezinye iikhamera eziphambili, kwiminyaka yakutshanje, zithole ukukwazi ukudubula nje kuphela imifanekiso kodwa zithatha ividiyo ephezulu (HD). Esi sici sivumela umsebenzisi ukuba atshintshe kwiifoto zokudubula kwiividiyo kunye neflick yeqhosha kwaye kuya kuvuya kakhulu.
Inketho yevidiyo ye-HD ivule ngokuqinisekileyo amathuba okusebenzisa ikhamera yedijithali. Nge-DSLR, uluhlu oluninzi lwama-lens lukhona kwaye lunokusetyenziswa kwimiphumo ebangelisayo kunye nesisombululo se-DSLRs yanamhlanje ivumela ividiyo yekhwalithi.
Kukho, ke, izinto ezimbalwa ofuna ukuba wazi ukuze ufumane uninzi kulo msebenzi.
Ifayile yeFayile
Kukho ifomathi ezininzi zeefayile ezikhoyo zokurekhoda kwevidiyo. I-Canon DSLRs isebenzisa ukuhluka kwefayile yefayile ye-MOV, iikhamera ze-Nikon kunye ne-Olympus zisebenzisa i-AVI ifom, kunye ne-Panasonic kunye ne-Sony basebenzisa ifomethi ye-AVCHD.
Ungakhathazeki kakhulu ngale nto, njengoko zonke iikopi zinokuguqulwa kwiifom ezahlukeneyo kwisigaba sokuhlela kunye nesiphumo.
Umgangatho weVidiyo
Uninzi lwabafundi abasebenzayo be-DSLRs ekugqibeleni bayakwazi ukurekhoda kwiHD epheleleyo (elinganayo nesisombululo sama- pixels angama- 1080x1920) ngesantya sama-24 ukuya kuma-30 ngesakhelo ngesibini (fps).
I-DSLR ye-Entry level ingasoloko ibhala kuphela kwisisombululo esincinane se-720p HD (isisombululo se-1280x720 pixels). Oku kusekho kabini isisombululo se-DVD format, nangona kunjalo, kwaye senza umgangatho obalaseleyo.
Nangona i-DSLR ineeplayseli ezininzi ezifumanekayo kunokuba zii-TV ezimbalwa kuphela - ii-4k okanye i-UHP (inkcazo ephezulu ephezulu) -yakwazi ukudlala ividiyo ephezulu ye-1080p HD.
Ukubukela Live
I-DSLR isebenzisa lo msebenzi ukurekhoda i-HD yevidiyo. Isibuko sekhamera sikhuliswa kwaye isibhengezo asisasetyenziswa. Kunoko, umfanekiso uhlawuleka ngqo kwikrini yekhamera yeLCD.
Gwema Autofocus
Ngenxa yokuba iividiyo zokudubula zidinga ukuba ikhamera ibe yimodi ye-Live View (njengoko ikhankanywe ngasentla), isibuko siya kuphakama kwaye i-autofocus iya kulwa kwaye iphuze kakhulu. Kukulungele ukubeka ingqwalasela ngokwayo xa udlala ividiyo ukuze uqinisekise iziphumo ezichanekileyo.
Indlela Yemiqulu
Xa udlala ividiyo, uluhlu lwakho lokukhethwa kwexesha lokuvota kunye nokuvulwa kuya kubonakala lincinci.
Xa udlala ividyo kwi-25 fps, umzekelo, kuya kufuneka ubeke isivinini sokuvalwa kwe-1/100 yesibini. Nasiphi na isistim esiphezulu kwaye ubeka ingozi ekudaleni "impembelelo" kwinqanaba elihambayo. Ukuze uzinikele ukufikelela kwibala elipheleleyo lokuvula, kukulungele ukudlala nge-ISO kwaye utyalomali kwisihlungi se- ND .
Tripods
Unokufuna ukusebenzisa i- tripod xa uvula ividiyo ye-HD, njengoko uza kusebenzisa i-screen LCD ukuze ulungise ividiyo. Ukubamba ikhamera ebude bomda ukuze ubone i-screen ye-LCD iya kubangela ukuba ulandelelanise.
Microphone zangaphandle
I-DSLR ifike nge-microphone eyakhelwe ngaphakathi, kodwa oku kuphela kubhala umkhondo we-mono. Ukongezelela oku, ukusondela kwemakrofoni kwi-photographer ngokubhekiselele kwisifundo ngokuqhelekileyo kuthetha ukuba iya kubhala ukuphefumla kwakho kunye nayiphi na intetho yekhamera.
Kukulungele ukutshala imali kwimakrofoni yangaphandle, ongayifumana ngokusondeleyo kwenzo njengoko kunokwenzeka. Uninzi lwe-DSLR lunikeza isiseko se-microphone stereo kule njongo.
IiLense
Ungakulibali ukuba unokusebenzisa ubuninzi beelensi ezifumanekayo kubasebenzisi be-DSLR kwaye usebenzise kuzo ukwenza iziphumo ezahlukeneyo kwimisebenzi yakho yevidiyo.
Ngokuqhelekileyo ii-camcorders eziqhelekileyo ziye zakha i-telephoto lens, kodwa ngokuqhelekileyo azikwazi ukukwazi ukufikelela kwiindawo eziphezulu. Unokusebenzisa iintlobo ezahlukeneyo zeelensi, ezifana ne-fisheye (okanye i-angle-wide angle), ukulungiselela indawo enkulu. Okanye unako ukuxhamla ubunzulu obuncitshiswe kwintsimi enikezwe ngeteksi engancinci ye-50mm f / 1.8.
Kukho amathuba amaninzi, ngoko ungesabi ukuzama iindlela ezahlukeneyo!
