Kuyini: HEVC? imphawu letibalulekile ngekhodekhi entsha

Njengoba wazi, sonke abathanda ukubukela amabhayisikobho, ama-video noma ukudlulisa ngekhwalithi ezinhle. Kodwa ngokuya isitoreji isiqophi kukhompyutha izinkinga eziningi ngokuvamile ezihlobene nokuntula banal isikhala. Esanda kutholakala indinganiso entsha, kanye nabasebenzisi abaningi wasuka masinyane umbuzo yemvelo: "Kuyini lokhu - HEVC»?. Cabangela izici eziyisisekelo ezimbalwa ezihlobene ukuqaliswa kanye ngokoqobo ngekhodekhi entsha.

Kuyini: HEVC

Uma sikhuluma movie ezilotshwe abezindaba esikhiphekayo, ngokuvamile nenkundla disk kuthinta kukhethwa indlela isiqophi kokucindezelwa. Kungokufanayo Blu-ray-akwazi ukugcina ingagcina movie kwencazelo eliphezulu ivolumu ezingaphezu kuka-25 GB. Kodwa, niyabo, ukugcina ifilimu kwi-hard drive yakho, ikakhulukazi uma ikwazi ngokucacile kungagcini, kusukela iphuzu eliwusizo umbono ngokuphelele okungalungile.

Ngenxa yale njongo, lo esephepheni omfisha, ukuvumela ngisho ngaphandle kokuyekethisa ku izinga ukunqinda wefayela yokugcina ngokusebenzisa izindlela ezikhethekile kokucindezelwa. Kodwa umkhuba, kuyini na? HEVC iyona ngekhodekhi eziphambili kakhulu, kungashiwo, ngisho revolution emkhakheni vidiyo. Kodwa lokho akusho ivumelane abathandi ubudala eliphezulu yevidiyo H.264?

Ukuphumelela High Coding Isiqophi: okungumsu esephepheni

Ukuze wenze lokhu, ubheke ukuqonda ayisisekelo isignali esephepheni. Iqiniso lokuthi kukhona omunye izindima eziyinhloko udlalwa ngokusebenzisa block ngobukhulu. Ukuze H.264, kuyinto 16 x 16, noma ingqikithi 256 pixels.

Ukuze H.265 entsha esezingeni block enjalo kungaba ngaphezulu izikhathi 16! Futhi uma sithatha ku-akhawunti ubuchwepheshe amabhlogo iyashintsha lapho ubukhulu block amuncwa umzimba ngokuqondile algorithm enqubeni kokucindezelwa, kulula ukubona ukuthi ngekhodekhi entsha okungukuthi, kakhulu "ukubekezela isithwathwa" kuya isinqumo eliphezulu futhi kuze kube manje isekela ngisho 8K (8192 x 4320 Amaphikseli ). Ungakwazi ukwengeza lapha ibuye zifana esephepheni umsebenzi. Ngakho, HEVC ngekhodekhi nge high quality umfanekiso kunganciphisa izinga kancane, futhi ngokufanelekile, usayizi wefayela. Isikhala kulondolozwa ngokuziqhathanisa ejwayelekile H.264 ongafinyelela 25-50%!

Ukusekela 4k futhi 8K: ngempumelelo kangakanani

Njengoba for ukusebenza kwe-codec ezinjalo, ekuqaleni ukubukeka kwakhe, engazange wawina udumo ekhethekile. Kwakuhlangene yokuthi asekele indinganiso entsha anganikeza kuphela ihluzo ezinamandla kakhulu futhi zanamuhla chips GeForce 970 noma 980.

Empeleni, izinga langempela le-wekhodi inqubo kwamanye amadivayisi kangako Kuthatha amahola angu 10-12. Ngakho, kusukela iphuzu eliwusizo umbono, indinganiso entsha bekulokhu ezingenanzuzo.

Ngokuhamba kwesikhathi, isimo sesishintshile, futhi manje ngesisekelo H.265 ubuchwepheshe isiqala zisetshenziswe emhlabeni. Ngokuya isikhala ekulondolozeni uma ziqhathaniswa H.264 zingancishiswa Ngokwesibonelo ngokwanele umlomo. Ngezinye isinqumo 720p inkomba ekulondolozeni imayelana 25%, kanye ne-4k izinga mbandela - ezingaphezu kuka-50%. By endleleni, uma usebenzisa sidabukile Blu-ray-disc, usayizi ividiyo yoqobo zingancishiswa cishe 10 izikhathi (uyokwenza "esingaphezudlwana ezingaphezu kwezingu-3 GB)!

ezintsha Okukhulu

Uma ubheka ezinye ezintsha, ezihlanganisa konke uvezwa izimfuneko ngekhodekhi entsha yilezi ezilandelayo:

• amaphrofayli Main ukwesekwa 8 no-10 izingcezu (esikhathini esizayo - 12 izingcezu);
• khona mgudumbili separable, nolimi futhi iqondiswa ASF yengetiwe izihlungi;
• ezinyakazayo isinxephezelo iwukuba ngaphakathi 1/8 of ngephikseli;
• Ukusebenzisa lesi simiso oluhambelana ukuqagela amaphutha kanye matrices ngokukhetha enqubeni esephepheni;
• Ngokuqhathanisa khona ukunyakaza Vector esephepheni wesifunda;
• umbuso ancike Uhlaka naphakathi-esephepheni.

Yiqiniso, ungaqhubeka uhlu esikhathini esizayo. Nokho, ngisho nalezi zibalo iyiphi professional sibhekene isiqophi ukuqonda, ungasho eziningi.

Ingabe iliphi isofthiwe isetshenziswa ukubukela amabhayisikobho ngefomethi entsha

Ngakho, ngo-ngekhodekhi waqonda. Kuyini (HEVC), Ngicabanga ukuthi okuncane kuyaqondakala. Manje phenya nezindaba kunazo ukuphokophela surely nentshisekelo iningi abasebenzisi. Yini esetshenziswa ukubuka ividiyo ifakwe algorithm entsha?

Ngomqondo onabile, injalo elula, ungasebenzisa abadlali isofthiwe. Omunye yezinto ezithakazelisa kakhulu, mayelana nokuthi zinengi, kuyinto ethize esinda isicelo ebhekiwe Daum PotPlayer. Uma ungathanda ukungatholi, ungasebenzisa ethandwa VLC Media Player, kuphela kubalulekile ufake inguqulo yakamuva, njengoba nje it has a esakhelwe ukwesekwa HEVC.

Nokho, naphezu kwakho konke lokhu kunobuhle obuthile, kungenzeka ukuba uqaphele eziningi izinkinga. Ngokwengxenye enkulu libhekisela kuphela yokuthi manje ungathola ku-inthanethi akuyona kangaka ibhayisikobho noma ividiyo ikhodi kusetshenziswa i-algorithm entsha. Uyini ezicindezelayo nakakhulu iba ukungabi khona ukwesekwa kusuka nomthengisi. Uma izinkinga isofthiwe ngandlela-thile ziye ixazululwe, kodwa leyo ndawo yeshashalazi ekhaya noma abakhiqizi TV Smart kukhona ekujaheni ukuze balukhulume okukhipha nge H.265 ukwesekwa. Yebo, futhi ngekhodekhi, nakuba kubhekwa wamavukelambuso, namanje ukusatshalaliswa ekhethekile ongakabi wathola. Kodwa Ngithemba ukuthi lokhu ngumkhuba yesikhashana.

esikhundleni umphumela

Nasi emfushane futhi konke kuhlobene indinganiso entsha e wekhodi wevidiyo. Yiqiniso, lapho abantu abathintekile, akuzona zonke izici lobuchwepheshe we ubuchwepheshe obusha, kodwa ngisho lokhu kwaziswa emfushane kuzosiza yimuphi umsebenzisi bafinyelele esiphethweni mayelana ezintsha ezinkulu, sekufanele awushiye kokusebenza kanye ngokoqobo evumela lobu buchwepheshe. Kodwa bebonke, bengathola zonke imibono yethu mayelana izinga nokucutshungulwa kolwazi vidiyo. Futhi, ngokusobala, ngokushesha ephelelwe yisikhathi H.264 ejwayelekile kuzoya lokulibala, ngoba ubuchwepheshe akemi namanje. Uma uthatha dogosrochnuyu ngombono, kwakungase kahle ukuthi esikhundleni HEVC ngekhodekhi ozokhula into ibe namandla nakakhulu.
