Ukuqonda i-Lossy ne-Lossless Without Compression
IiVideos zithatha indawo eninzi-nje ukuba zinjani ngokubanzi ngokuxhomekeke kwifomathi yevidiyo, isisombululo kunye nenani lamafowuni ngesibini okhethayo. Ukunganyanzelwanga 1080 Ividiyo yevidiyo ye-HD ithatha malunga ne-10.5 GB yeendawo ngomzuzu wevidiyo. Ukuba usebenzisa i-smartphone ukudubula ividiyo yakho, iphepha le-1080p lithatha u-130 MB ngomzuzu weevidiyo, ngelixa ividiyo ye-4K ithatha i-375 MB yendawo yefilimu nganye yamzuzu. Ngenxa yokuba ithatha indawo eninzi kangaka, ividyo kufuneka icinezelwe phambi kokufakwa kwiwebhu. "Ugxininiswe" uthetha ukuba ulwazi lupakishwe kwisithuba esincinci. Kukho iintlobo ezimbini zoxinzelelo: ukulahleka kunye nokungaphumeleli.
Ukunyanzeliswa kokulahlekelwa
Ukunyanzeliswa kwelahleko kuthetha ukuba ifayile exinyiweyo ineenkcukacha ezimbalwa kuyo ngaphandle kwefayile yangaphambili. Kwezinye iimeko, oku kuguqulela iifayile eziphantsi, kuba ulwazi "lulahlekile," ke igama. Nangona kunjalo, unokulahlekelwa ngumlinganiselo omkhulu wedatha ngaphambi kokuba uqale uqaphele umahluko. Ukunciphisa ukulahleka kubangela ukulahlekelwa ngumgangatho ngokuvelisa iifayile ezincinci. Ngokomzekelo, iiDVD zixinyizwe ngokusebenzisa ifomathi ye-MPEG-2 , engenza iifayile ezili-15 ukuya kuma-30 amancinci, kodwa ababukeli basoloko befuna ukubona iiDVD njengemifanekiso ephezulu.
Uninzi lwevidiyo elayishiwe kwi-intanethi isebenzisa ukunyanzeliswa kwelahleko ukugcina ubungakanani befayili ngelixa lihambisa umkhiqizo ophezulu.
Ukunyanzeliswa okungenasiphelo
Ukunyanzeliswa kokulahlekelwa yinto efana nokuthi, ukunyanzeliswa apho kungekho nto yolwazi elahlekileyo. Oku akukona nje kuncedo njengenkcitho yokulahleka ngenxa yokuba iifayile zihlala ziphela zifana nobukhulu obufanayo njengoko zazikho ngaphambi kokuncintisana. Oku kungabonakala kungenanto, njengokunciphisa ubukhulu befayile yinjongo ephambili yokuxinzelela. Nangona kunjalo, ukuba ubungakanani befayile abuyiyo ingxaki, ukusebenzisa ukunyanzelisa ukungaphumeleli kubangela umfanekiso ophezulu. Umzekelo, umhleli wevidiyo ohambisa iifayile ezivela kwikhompyutha enye ukuya kwelinye usebenzisa i-hard drive angakhetha ukusebenzisa ukunyanzeliswa kokulahlekelwa ukugcina umgangatho ngelixa esebenza.
