Indlela iFayile Compress ichaphazela ngayo umfanekiso kunye nomgangatho ophezulu
Xa ividyo, ifoto okanye umculo igcinwa kwifomati yedijithali umphumo unokuba ifayile enkulu enzima ukuyifaka kwaye isebenzise imemori eninzi kwikhompyutheni okanye kwi-hard drive eya kugcinwa kuyo. Ngako oko, iifayile zixinyiwe - okanye zenziwe zincinci - ngokususa enye idatha. Oku kubizwa ngokuthi "ukulahlekelwa".
Iimiphumo zoxinzelelo
Ngokuqhelekileyo, ukubala okunzima (i-algorithm) isetyenziswe ukuze imiphumo yedatha elahlekileyo ingabonakali kwiso kwividiyo nakwiifoto, okanye ayikwazi ukuvalelwa kumculo. Ezinye zeenkcukacha ezibonakalayo ezilahlekileyo zixhamla ukuba iso luntu lingakwazi ukwenza ukungafani okuncane kumbala.
Ngamanye amagama, ngeteknoloji yoxinzelelo olufanelekileyo, akufanele ukwazi ukulahleka komfanekiso okanye umgangatho wezwi. Kodwa, ukuba ifayile kufuneka icinezeleke ukuba ibe yincinci kunefomathi yayo yasekuqaleni, isiphumo asikwazi kuphela ukuqonda kodwa sinokwenza umgangatho wezithombe unobungozi kangangokuthi le vidiyo ayinakubonakala okanye umculo uphahla kwaye ungenasiphelo.
Inkcazo ephezulu ye-movie ingathatha imemori emininzi - ngamanye amaxesha i-gigabytes enye. Ukuba ufuna ukudlala le movie kwi-smartphone, kufuneka uyenze ifayile encinane okanye ifumane yonke imemori yefowuni. Ukulahlekelwa kwedata kwiinkcenkceshelo eziphezulu akubonakali kwi-screen intshi yesine.
Kodwa, ukuba ufuna ukusasaza loo fayile kwi- Apple TV, i-Roku Box, okanye ifowuni efanayo , exhunyiwe kwi-TV yesikrini esikhulu, ukuxinwa kuya kuba kungabonakali kuphela, kodwa kuya kwenza ukuba ividiyo ibonakale iyingozi kwaye ibe nzima bukele. Imibala ingabonakala ikhuselekile, ingabonakali. Iingcipheko ziyakwazi ukuphazamiseka kwaye zitshintshwe. Iimfudu zingaphazamisa okanye zenze i-stutter. Le ngxaki ngokusebenzisa i-AirPlay kwi-iPhone okanye kwi-iPad. I-AirPlay ayifuni nje ukusakaza kumthombo. Endaweni yoko, iyakhuphaza ukudlala kwifowuni. Iimvavanyo zokuqala kwi-AirPlay ziye zisoloko zixhoba kwimiphumo ye-compression high.
Izigqibo zokunyanzelisa - I-Quality vs Space Save
Ngelixa ufanele uqwalasele ubukhulu befayili, kufuneka ulinganise ngokugcina umgangatho womculo, iifoto okanye ividyo. I-drive yakho yesigxina okanye isikhala se-imeyile yesiganeko sinokulinganiselwa, kodwa ukuqhutshwa kwangaphandle kwezinto ezikhuni zihla ngexabiso lamandla amakhulu. Ukhetho lunokuba luninzi kunye nomgangatho. Unokufumana amawaka eefayile ezixinzelelweyo kwi-hard drive ye-500 GB , kodwa unokukhetha ukuba nekhulu kuphela zeefayili eziphezulu.
Uyakwazi ukusetha iinqununu malunga nokuba ungakanani uxwebhu olufakwe ngaphakathi okanye olugcinweyo oluciniweyo. Kukho rhoqo izicwangciso kwiimpawu zomculo ezifana neTunes ezivumela ukuba ubeke izinga lokunyanzeliswa kweengoma ozifakayo. Umculo uncoma ukuba uphezulu kakhulu ukuze ungalahlekelwa nantoni yeengoma - ii-256 kbps ze-stereo ubuncinci kwiifom ze-HiRes zomsindo ukuvumela amanqanaba athile aphezulu. Iifayile zeJpeg zimele zibekwe kwisayizi esiphezulu ukugcina umgangatho wezithombe. Iifrimu zeenkcazo eziphakamileyo kufuneka zihlanjululwe kwifomathi yazo yokugcina yedatha njengeH.264, okanye i-MPEG-4.
Injongo yokuxinwa kukufumana ifayile encinci ngaphandle kokulahlekelwa komfanekiso kunye / okanye idatha yezwi ebonakalayo. Awukwazi ukungahambi kakuhle ngeefayile ezinkulu kunye nokuncinci ngaphantsi ngaphandle kokuba uphumelele kwithuba.
