Yog li, peb tuaj yeem hais nrog kev ntseeg siab tias lub koob yees duab no tso cai rau koj los qhia meej txog kev muaj tswv yimcov neeg siv muaj peev xwm hais txog kev kaw video.
Cov ntaub ntawv khaws cia
Ob hom ntawv cim xeeb ceev, XQD thiab CompactFlash, yog siv los khaws cov duab thiab yeeb yaj kiab. Nws yuav tsum raug sau tseg tias thaum siv thawj zaug ntawm cov kev xaiv no, qhov ntev ntawm kev txhaj tshuaj tas li yog kwv yees li 20% siab dua. Qhov no tseem ceeb heev thaum siv Nikon D4S ua lub koob yees duab reporter. Cov slots tuaj yeem tuav peb txoj hauv kev. Nrog rau thawj ntawm lawv, cov ntaubntawv povthawj siv yog alternated nyob rau hauv xov xwm kom txog rau thaum nws yog tag nrho, nrog rau qhov thib ob - ib txhij ntawm ob lub drives, thiab nrog rau qhov thib peb, cov ntaub ntawv video thiab cov duab yog khaws cia nyias. Tag nrho cov no tuaj yeem kho tau los ntawm tus neeg siv. Cov ntaub ntawv yees duab muab faib ua xya nplooj ntawv. Ntxiv nrog rau cov ntaub ntawv tseem ceeb, nws muaj cov ntaub ntawv ntxiv (kev ci ntsa iab histogram, cov ntaub ntawv GPS, nrog rau lwm yam kev tua phom).
Data transfer
Tus qauv siv thev naus laus zis ntawm kev hloov pauv cov ntaub ntawv nrawm, uas yog qhov tseem ceeb tshwj xeeb thaum ua cov ntawv ceeb toom duab. Txhawm rau kom muaj peev xwm txuas tau sai rau cov khoom siv txuas ntxiv, qhov niaj zaus HDMI thiab USB 2, 0 interfaces, nrog rau qhov tshwj xeeb Gigabit 100/1000TX Ethernet chaw nres nkoj, tau muab ntawm no. Koj tuaj yeem txuas tau yooj yim txuas cov hlua txuas rau Nikon D4S lub koob yees duab, nrog rau lub router siv cov software tshwj xeeb (qhov no tso cai rau koj los tswj txhua lub koob yees duab lub peev xwm los ntawm lub computer).
