Fasaha aiki tare da firam galibi ana samun su ta hanyar sarrafa adadin wartsakewa na allon LED da firam ɗin siginar shigarwa, ta yadda za a iya nuna allon bidiyo a hankali. A cikin ɓangarorin allo da yawa, fasahar haɗin gwiwar firam ɗin na iya guje wa tsagawar allo da tsagewa da sauran matsaloli.
7.Bayyana Fasahar Jinkiri
Lokacin jinkirin nuni na ƙaramin allo na LED yana da matukar mahimmanci saboda a cikin wasu aikace-aikacen, kamar gasar E-Sports da kide kide da wake-wake, tsayin lokaci mai tsawo na iya haifar da bidiyo da sauti ba tare da daidaitawa ba, wanda ke shafar kwarewar mai amfani. Don haka, masu sarrafa bidiyo suna buƙatar sanye take da fasahar jinkirin nuni don cimma mafi ƙarancin lokacin jinkiri.
8.Multi-signal Technology Input
A wasu lokuta, ya zama dole a nuna hanyoyin sigina da yawa a lokaci guda, kamar kyamarori da yawa, kwamfutoci da yawa da sauransu. Saboda haka, na'ura mai sarrafa bidiyo yana buƙatar samun fasahar shigar da sigina da yawa, wanda zai iya karɓar maɓuɓɓugar sigina da yawa a lokaci guda, kuma ya canza tare da haɗuwa da nuni. A lokaci guda, fasahar shigar da sigina da yawa kuma tana buƙatar magance matsalolin ƙudurin tushen sigina daban-daban da ƙimar firam daban-daban don cimma daidaiton nunin bidiyo mai santsi.
A taƙaice, mabuɗin fasaha na ƙaramin mai sarrafa bidiyo na allo na LED sun haɗa da fasahar canza sarari launi, fasahar haɓaka hoto, fasahar gyara launi, fasahar sarrafa sikelin launin toka, fasahar daidaita firam, fasahar jinkirin nuni da fasahar shigar da sigina da yawa. Aikace-aikacen waɗannan fasahohin na iya inganta ingantaccen tasirin nuni da ƙwarewar mai amfani na ƙaramin allon farar LED. A nan gaba, tare da ci gaba da ci gaban fasaha, mai sarrafa bidiyo za a ci gaba da ingantawa da kuma inganta shi don aikace-aikacen ƙananan allon LED don kawo ƙarin aiki mai ban mamaki.
