Yintoni na: HEVC? Iimpawu eziphambili codec entsha

Njengoko usazi, sonke thina bathanda ukubukela imifanekiso eshukumayo, iividiyo okanye zokusiwa esemgangathweni. Kodwa ngokwemiqathango yokugcina ividiyo kwikhompyutha iingxaki ezininzi ezinxulumene ngokuqhelekileyo ngokunqongophala banal indawo. Kakhulu kutshanje njengentsha esezantsi, kwaye abasebenzisi abaninzi nangoko kwavela umbuzo yendalo: "Yintoni na le - HEVC»?. Cinga nje izinto ezimbalwa esisiseko enxulumene ukuphunyezwa ngokoqobo codec entsha.

Yintoni na: HEVC

Ukuba sithetha movie ebhalwe kwi kumajelo elisusekayo, ngokokuqhelekileyo ubukhulu idiski kuchaphazela ukukhetha indlela yokuzonwabisa ucinezelo. Efanayo Blu-ray-Recordable zinokugcina bhanyabhanya definition etsholo phezulu abangaphezu kwama-25 GB. Kodwa, uyabona, ukuba ugcine ifilim kwi hard drive yakho, ingakumbi xa umthamo wayo umda ngokucacileyo, ukusuka kwindawo ezenziwayo kungafanelekanga ngokupheleleyo.

Ukulungiselela le njongo, i ikhowudi umboniso, evumela ngaphandle kokuqhatha kubulunga ukunciphisa ubungakanani ifayile lokugqibela ngokusebenzisa iindlela ezizodwa ucinezelo. Kodwa practice, yintoni na? HEVC yeyona codec eziphuhlileyo, kunokuthiwa, nkqu revolution kwinkalo ye vidiyo. Kodwa yintoni na zilungele abathandi endala ezikumgangatho ophezulu codec H.264?

Bongeka High Video Coding: izisekelo ikhowudi

Ukuze wenze oku, jonga ukuqonda iziseko umqondiso ikhowudi. Into yokuba kukho enye lweendima eziphambili udlalwa ngokusebenzisa block inkulu. Kuba H.264, i-16 x 16, okanye abangama-256 pixels.

Kuba H.265 omtsha standard ibhloko onjalo kuba amaxesha 16 ngaphezulu! Kwaye ukuba uthathe ingqalelo thina iteknoloji iibhloko ziyatshintsheka xa ubukhulu block ako ngqo algorithm kwinkqubo ucinezelo, kulula ukubona ukuba codec omtsha kukuthi, inkoliso "ukumelana" lizakuya kusombululo eliphezulu kwaye ukuza kuthi ga ngoku uxhasa noba 8k (8192 x 4320 pixels ). Ungadibanisa apha ibuye zifana ikhowudi function. Ngenxa yoko, HEVC codec nge high quality umfanekiso nga ukunciphisa izinga bit, kwaye ngokufanelekileyo, ubukhulu ifayile. Space ukugcina xa kuthelekiswa nomgangatho H.264 unako ukufikelela 25-50%!

Inkxaso 4k no 8k: kakuhle kangakanani

Ke ukusebenza codec enjalo, ekuqaleni ngenkangeleko yakhe, yena akazange yaphumelela ithandwa okhethekileyo. Kwakunxibelelene kukuba inkxaso asemgangathweni entsha ukubonelela kuphela chips yemizobo zinamandla kwaye mihla GeForce 970 okanye 980.

Eneneni, inkqubo enkhowudingi yokwenene kwezinye izixhobo ezinamandla kangako kuthatha malunga 10-12 iiyure. Ngoko ke, ukususela ngamehlo izinto ezenziwayo, umgangatho omtsha iye bebonke.

Ekuhambeni kwexesha, le meko iye itshintshile, kwaye ngoku ngokusekelwe lobuchwepheshe H.265 luyaqala ukuba kusetyenziswa jikelele. Ngokwemiqathango ogcino isithuba xa kuthelekiswa ne-H.264 kungancitshiswa umzekelo ngokwaneleyo umlomo. Xa isigqibo ogcino Isalathisi 720p yi malunga ne-25%, kunye 4k umgangatho kunciphiso - ngaphezu kwe-50%. Ngendlela, ukuba usebenzisa i lwengoma Blu-ray-idiskhi, ubukhulu ividiyo yoqobo kungancitshiswa phantse 10 amaxesha (uya 'nobunzima kancinane ngaphezu 3 GB)!

ezintsha eziphambili

Ukuba ujonga ezinye ezintsha, kuquka yonke into inikwa yeemfuno codec ezintsha zezi zilandelayo:

• inkxaso iinkangeleko Main 8 amasuntswana 10 (kwixesha elizayo - amasuntswana 12);
• ubukho ezikumila kumacala mabini separable, engenakususwa kunye wayalela ASF zelwe amacebo;
• imbuyekezo motion ukuba kwisithuba 1/8 we pixel;
• Ukusetyenziswa kwenkqubo iimpazamo ukuqikelela olwenziwayo kunye matrices kukhethwa kwinkqubo ikhowudi;
• yesekethe phambi motion yomzobo ikhowudi athelekisekayo;
• ulawulo-oxhomekeke intra-isakhelo ikhowudi.

Kakade ke, uyakwazi ukuqhubeka uluhlu kwixesha elizayo. Kodwa, nkqu ezi zibalo na senze yobuchule kunye nevidiyo encoding, uthi lukhulu.

Yintoni software lisetyenziswa ukubukela iimovie ngefomathi entsha

Ngoko ke, ngenxa codec yakuqonda. Yintoni na (HEVC), ndicinga ukuba iyaqondakala kancinci. Ngoku vula kwimiba njengezona nkalo zitshisa ibunzi ukuba uza kuba nomdla ngokuqinisekileyo inkoliso abasebenzisi. Yintoni kusetyenziswa ukujonga ividiyo ezinonxulumano ubuchule ezintsha?

Enyanisweni, ekwimo yakhe kwecacileyo, ungasebenzisa abadlali software. Enye yezona umdla, njengoko amaninzi, Daum PotPlayer ezizodwa wasinda isicelo okungqalileyo. Ukuba ngaba ukhetha ukuba, ungasebenzisa i ethandwa VLC Media Player, kuphela kuyimfuneko ukufaka uguqulelo oludlulileyo, njengokuba kuphela has eyakhelwe-ngaphakathi inkxaso HEVC.

Noko ke, nakuba zonke izinto, kusenokwenzeka ukuba uqaphele ezininzi iingxaki. Ubukhulu becala libhekisela kuphela kukuba ngoku ungafumana kwi Internet ayikho kangako movie okanye ividiyo enkhowudwa usebenzisa i algorithm entsha. Yintoni eyona iyabenzakalisa ngakumbi kukunqongophala kwenkxaso evela umthengisi. Ukuba imiba software thile ziye isonjululwe, le nkundla ekhaya okanye abavelisi TV Smart Musa ukungxama kukaZwilakhe imveliso kunye H.265 inkxaso. Ewe, kwaye codec, nangona kucingwa mbuso, kusekho unikezelo ezizodwa alukayifumani. Kodwa ndiyathemba ukuba lo mba okwethutyana.

kunokuba nesiphumo

Nantsi i emfutshane bonke enokuthanani umgangatho entsha yevidiyo encoding. Kakade ke, kukho uxhelekile, asizizo zonke kwiinkalo zobugcisa ubuchwepheshe obutsha, kodwa le ngcaciso emfutshane iya kunceda nawuphi na umsebenzisi bazobe kwisigqibo malunga ezintsha eziphambili, awushiye ukuphunyezwa kunye nokusetyenziswa ngendlela ebonakalayo yezi teknoloji. Kodwa becala, ziphucule zonke iingcinga zethu malunga umgangatho kunye processing of ulwazi lwevidiyo. Kwaye, kuyabonakala ukuba, kungekudala lixesha standard H.264 uya kungena zisabonakala, ngokuba obu bugcisa na ukuma. Ukuba uthatha dogosrochnuyu imbono, kusenokwenzeka kakuhle kakhulu ukuba endaweni HEVC codec iza kuphuhlisa into enamandla ngakumbi.
