Umgangatho wokusasazwa: Kuthetha ukuthini ukuThunyelwa koNxibelelwano olungabonakaliyo


2017 NAB Bonisa Ukungeniswa koHlelo
NguRush Beesley, uMongameli uRUSHWORKS

"I-Quality Distribution", bam bahlobo, lixesha elifanelekileyo. Ngenxa yezizathu eziza kubonakala kule ntetho, ndihlala ndichaze "umgangatho wokusasaza" njengokuba "umgangatho wento oyifakayo". Le ngcamango iyakwanelisekile ukuba isiphaluka esifutshane sibe nengxoxo emibini kunye nokuvumela ukuba uqalise incoko yababini.

Ngoko njani nina Ichaza umgangatho wokusasazwa? Ukubonisa ukuba kufuna into engqiqo ngakumbi kunomgangatho wento esasazwayo, makhe sihlolisise iinguqu ezininzi ezifakayo kule ngcamango ephepheni. Akukho myalelo othile.

  1. Ifilimu kunye neVidiyo

Ngaba ucinga ukuba ifilimu ingumgangatho ophezulu kunevidiyo? Abantu abaninzi benza. Okanye ngaba. Iminyaka emininzi edlulileyo uluvo oluninzi luyathanda ifilimu, icacisa ividiyo ngokungalokwazi ukusingatha uluhlu olushukumisayo lwe-exposure kunye nombala okhoyo ngokufumana ifilimu. Kwaye zichanekile. Isisombululo sevidiyo ye-analog yayinganiselwe kakhulu, kunye ne-525 "imigqa" yevidiyo ukusuka phezulu kwesikrini ukuya ngasezantsi, kungakhathaliseki ukuba ubukhulu bunjani isikrini. Okukhudlwana kwesikrini, okanye ngokusondela kwakho, unokuqalisa ukubala loo miqolo.

Abantu bathelela kwiivenkile zee-movie ukuze babone ukuveliswa kwe-Big Screen, abangagqithwanga ngamandla angalinganiswanga iteknoloji yethelevishini. Ziziphi iimeko eziye zatshintsha. Ngokuveliswa kwevidiyo yedijithali, kunye nokuqhubela phambili kokunyuka kwama-pixel ukunyaniseka, into obukeleyo kwi-Big Screen inokuthi idutshulwa kwividiyo kwaye ihanjiswe kwibala Sathelethi.

Kwaye abantu benza amashishini kunye neefilimu kunye nee-smartphone. Ndicela umngeni kumntu ukuba abukele isiqwenga se "Halai" ezintlanu-O "kwaye angafungi ukuba uphendulelwe kwifilimu. Gosh. Ngokuqinisekileyo Bukeka Ngathi ifilimu, akunjalo? Heck ... ke kufuneka ukuba. Kunene? Uluhlu oluninzi ngokuphambene, imibala enamandla. Ayikho into yokuba ndikhulile kunye kwaye ndiyabona njengevidiyo. Ayikho isilumkiso se-spoiler apha. Yithi nje, "Kulungile, Google".

  1. Umgangatho wefreyimu

Khumbula, sithetha "ngomgangatho wokusasazwa". Ireyithi yesreyithi yevidiyo kwi-US iminyaka engaphezu kwamashumi asixhenxe anesihlanu i-29.97 ifowuni ngesibini. Yini i? Apho ayenze khona ukuba Inombolo evela? TMI kule ngxoxo. Ukufaneleka ukutsho ukuba yi-NTSC standard (apho abanye bethu bahlonela inja endala bathi akukho Mbala Ofanayo). Ukongezelela ukuba iifowuni "zithengiswa", nto leyo ithetha ukuba kukho ngokwenene ii-60 kummandla ngamnye oqukethe isakhelo esisodwa.

Ngoko ngexesha lokudlala umdlalo uhamba kakuhle. Okuthakazelisayo, xa abantu beyibona bayayibona njengevidiyo kwaye bengabikho ifilimu. Kutheni oko? Kungenxa yokuba ifilimu ayinakujongana ne-hocus ye-eleksi ye-field interlacing field. I-shutter ivula i-1 / 24th Lwesibini kwaye uthabatha isakhelo esipheleleyo sento. Ngoko isreyimu yentlawulo yi-24 ozimele ngesibini, kungekhona i-30. Oko kuthetha ukuba i-20% engaphantsi "isenzo" esibhalwe kwisakhelo ngasinye.

Xa ubona i-24 fps yokudlala, ubuchopho bakho bubona ukuba u-stutter omncinane phakathi kwamafowuni. Awucingi ngako, kodwa kwenzeka. Kwaye ke, bahlobo bam, kutheni bekuqhele ukuba kulula ukubona phakathi kwefilimu nevidiyo.

Kodwa sithetha ngomgangatho wokusasazwa apha. Ukusasaza umxholo okwenziwe kwiphephancwadi, kufuneka udlulise ifilimu usebenzisa ikhamera ekhethekileyo yekhamera ene-shutter eyenza i-hocus yangasese yangoku, enezela iifayile eziphindaphindiweyo zonke ezinye iisakhelo ukuvumelanisa ukungafani kwexesha.

Ekubeni awukwazi "ukusasaza" ifilimu, yilokho ubonayo. Ukuveliswa kwevidiyo yefayile. Kwaye ulahlekelwa luhlu olukhulu lwefilimu kunye nobuqhetseba balobugcisa kwiinkqubo.

Kodwa le nto ikhutshwe ngeteknoloji yevidiyo (empeleni iteknoloji yekhompyutha) kwiikhamera ezivumela ukuba imifanekiso ibhalwe phantsi malunga naluphi na uhlaka lwesitimu, ukukhupha i-physics yokuthwebula ifilimu. Ngokuphawulekayo, "ukubukeka kwefrimu" ngoku kuyafumaneka ngokusebenzisa i-24fps kwimodi "yokuqhubekayo", oku kuthetha isakhelo esipheleleyo kwaye singabandakanyeki.

  1. Umgangatho wokusasazwa ngoonjiniyela beTV

Kwiminyaka emininzi edlulileyo ndavelisa iirhwebo ezibiza ngexabiso eliphantsi kwesikhululo seTV, kwaye ndithatha enye yeekopi kwisikhululo esilungiselelwe ukuba senze indawo. Esi sikhululo sasisisitabane somnatha omkhulu (apho kukho ezintathu kwixesha).

Ndathatha i-2 "tape kwi-injini 'yokulawula umgangatho' ngoko kunokuba kuthathwa njengento efanelekile yokusasazwa. Ufake itekisi kwi-VTR ye-Volkswagen-size VTR, wathintela iqhosha lokudlala, kwaye wayejonge ngokubhekiselele kwizinto zakhe zobugcisa. Emva koko wamisa itheyipu, waphendukela kum kwaye wathi, "Asikwazi ukuwamkela le tape. Akusasazisi umgangatho. "Ndandiziqhenya ngokwenene into endiyibethe kuyo, kwaye yayibukeka imangalisa kwi-intanethi ye-high quality quality monitor, idlala ngokungafaniyo.

Ndathi, "Uh ... uthetha ukuthini ... ungasasazeli umgangatho? Kubukeka bukhulu kum! "Wandula ke wachaza ngolwimi ndiyakwazi ukubiza kuphela i-jabberwoky. Into ethile malunga "nentonga yokuvumelanisa kunye nebhantshi langaphambili". Walahla iteksi. Kwaye akazange akhangele iliso.

  1. Imiba yohlobo. Kuxhomekeka.

Ukukhawuleza. Abantu ngoku baqhutyelwa ukuvelisa umxholo kwi-4K ... kunye nangaphezulu. Nangona ndiqonda ukuba amanye amaphikiseli "angcono", cinga ngawo. Ngokuqinisekileyo, ukuba ubukele isikrini esikhulu kwi-movie okanye kwikhaya lasekhaya. Abaxhasi be-4K basikisela ukuba sisondele kakhulu kumboniso othobekileyo we-4K ukuze "siqonde" umehluko. Kwenene? Ngubani ofuna ukuhlala kufuphi neTV enkulu ukuyixabisa?

Kwaye nantsi ingqwalasela ebaluleke kakhulu, kunikwa ukuba "ukusasazwa" kwendabuko njengoko siyazi ukuba kususwa ngokukhawuleza ngokufudukela kwezinye iindlela zokuhambisa umxholo. Ixesha elitsha "I-OTT", ndiyakholwa, into endiyitshelileyo ibonisa "I-Top Top". Ukuzonwabisa ukuba izinto ezingenanto zinganamathela njani. Naluphi na umgangatho, le nkonzo ye-subscription njenge-Netflix, i-Hulu kunye namanye amaninzi asebenzisa iibhokisi ze-intanethi ezingabizi njengeRoku 'yokumkela', ukususa iindonga zokusasaza kunye neenkqubo eziqhelekileyo ezivela kwi-equation viewer.

Ngoko ke kucetyiswa ukuba igama elithi "umgangatho wokupapashwa" litshintshwe. LALA KAKUHLE. Umgangatho we-OTT, mhlawumbi? Apho izibonakaliso zinyanzelisiwe kwaye izigqibo ziyancipha ukwenzela ukuba izigidi zabantu zithintele kwaye zihlale zifuna ukuhamba kwee-bandwidth kunye nethemba lokumisa amancinci, ukubetha kwevidiyo kunye nekhwalithi yevidiyo ehlekisiwe xa ihlabelela, "Akuyikho iTheknoloji enkulu ???"

Musa ukufumana i-TOO kufuphi ne-monitor yakho enkulu. Unesibopho sokubona isiqwenga sezikwere ezincinane esithombeni xa into ethile ihamba ngokukhawuleza. Umgangatho uhlala ulungiswa ngokufanelekileyo ekunikezeni ngaphantsi ukuya ngaphezulu.

Kwaye ekugqibeleni, ubungakanani obubalulekileyo xa uphakathi kweempiliya eziphendulele 'kwii-smart devices' zazo ukuba zibukele umxholo xa zifuna, apho zifuna khona. Ungathatha i-4K kwaye uyiqhube kwi-Topeka xa ifika kumgangatho wesithombe kwiikrini ezincinci. Ngokuqinisekileyo izikrini zinokusombululo esikhulu. Kodwa yenza oku kum. Bamba umxholo othile wekhontrakthi yevidiyo kwaye uqale ukubukela. Unayo 'ifowuni' malunga ne-12 "ebusweni bakho, kunjalo? Khangela ubungakanani baloo ngxande, uze ucinge ukuba udibene kumqolo wokugqibela we-Admiral Twin Drive-Inatre kunye nokubukela umfanekiso wefilimu ovela kwi-300 'away. Loo mfanekiso ungayisisombululo sesinye kwisisombululo kwaye iya kukhangelelana nawe kwisihlalo somqhubi. Okanye naphi na.

Yaye yile ngongoma. Ukuba umfanekiso usemncinci ... okanye ude ude ... awufunanga zonke izigqibo ukuze ujonge umboniso. Ngoko ngokuza ulande into yokubukela, qiniseka kwaye uhlolisise ukhetho lwekhwalithi olukhoyo. Ukuba omnye wabo "Usasazo" ... nceda ufunde kwakhona eli nqaku ngaphambi kokuthenga.
