- Ikhwalithi yangempela yekhamera yewebhu incike ku-OBS kanye nezilungiselelo zesistimu kanye nekhamera uqobo.
- Ukulungiswa okuhle ngesandla (ukugxila, ukuvezwa, ukukhuphuka) kanye nokukhanya okwanele kwenza umehluko omkhulu kunesinqumo ngokwaso.
- Izintambo, imbobo ye-USB, kanye ne-bitrate yokurekhoda noma yokusakaza kuthinta ngqo ubukhali kanye nokuzinza kwesithombe.
- Ukuhlela indawo kanye nokuhlelwa kabusha kwevidiyo kubalulekile ekuqinisekiseni ukuthi umbhalo kanye nemininingwane emincane kucacile ekuqopheni nasekusakazweni bukhoma.
Uma unekhamera yewebhu efanelekile, njenge-Logitech C920 noma ikhamera ye-4K, futhi isithombe sisabonakala sifiphele, singathandeki, noma singekho kulokho obukulindele, kuyinto evamile ukuzibuza ukuthi yini engalungile. Ngokuvamile, akuyona ikhamera ngokwayo eyinkinga, kodwa kunalokho ukusetha, ukuxhumanisa amakhebula, ukukhanya, kanye nesofthiwe oyisebenzisayo ukuthwebula ividiyo, njenge-OBS (noma i-"OBA" uma uyithayiphe ngokushesha), kanye nokuxazulula izinkinga ze-PC peripherals.
Ezimweni ezivamile, njengokufuna ukufunda umbhalo ongezansi kwesikrini, ukuqopha ividiyo ye-YouTube yesikrini esigcwele, noma ukusakaza bukhoma ngenkathi ubonisa okwenzekayo kusikrini, ikhamera yewebhu ibonakala inganele. Kodwa-ke, ngokulungiswa okucatshangelwe kahle, ungathuthukisa kakhulu ikhwalithi ebonakalayo ngaphandle kokushintsha ikhamera yakho noma ukuchitha imali eningi emishinini emisha.
Kungani ikhamera yakho yewebhu engu-1080p noma engu-4K ingabukeki kahle njengoba kufanele
Into yokuqala okufanele uyiqonde ukuthi i-resolution (1080p, 4K, njll.) akuyona yonke into. I-Logitech C920 ku-1080p, exhunywe ngekhebula le-USB extension futhi isebenza ku-Windows 10, inganikeza isithombe esihle kakhulu, kodwa uma kukhona okungahambi kahle ku-chain, ikhwalithi yehla kakhulu. Ezimweni eziningi, inkinga isekuhlanganisweni kwe-resolution, i-bitrate, i-compression, kanye nokukhanya.
Uma abasebenzisi bekhononda ngokuthi ingxenye engezansi yevidiyo ayifundeki, noma ukuthi umbhalo osesikrinini awuhlukaniseki, kunezici ezimbili ezihilelekile cishe njalo: okokuqala, isofthiwe (njenge-OBS) ikhulisa noma icindezela isithombe ngokweqile, kanti okwesibili, ukugxila nokubukhali kwekhamera yewebhu akulungisiwe kahle . Ngisho noma inzwa inesisombululo esingaphezu kokwanele, imininingwane emincane iyalahleka.
Esimweni esithile sokusebenzisa ikhebula le-USB elisezingeni eliphezulu , kukhona okunye okungaba yimbangela: ikhwalithi yekhebula uqobo. Uma kuyikhebula elide kakhulu, elishibhile noma elingenawo amandla engeziwe, kungenzeka ukuthi kulahleke isignali. Lolu hlobo lwezinkinga lungabangela ukuyeka ukusebenza, izinto ezidaliwe, ukwehla okuzenzakalelayo kwesisombululo noma izinga lozimele , okuholela esithombeni esibi.
Uhlobo lwembobo kanye nenguqulo ye-USB oyisebenzisayo nakho kunomthelela omkhulu . Uma uxhuma ikhamera yewebhu kuhabhu namanye amadivayisi asebenzisa i-bandwidth, noma kumbobo ye-USB 2.0 egcwele kakhulu, uhlelo lungaphoqa ikhamera ukuthi isebenze ngezilungiselelo ezilondolozayo: ukulungiswa okuphansi kwangempela, ukucindezela okwengeziwe, kanye nokushelela okuncane.
Elinye iphuzu elivame ukunganakwa ukuthi i-Windows 10 kanye nezinhlelo zokusebenza ezifana ne-OBS zabelana ngezilungiselelo zekhamera. Kungenzeka ukuthi olunye uhlelo lushiye amapharamitha okuzenzakalelayo ehlelwe ngendlela engafanele (inzuzo ephezulu kakhulu, ukuvezwa okungalungile, i-twitchy autofocus, njll.), okungathinta kabi ikhwalithi yesithombe sokugcina ngaphandle kokuthi uqaphele. Uma ungaqiniseki, hlola futhi izibuyekezo kuma-peripherals kanye nezesekeli ezingase zithinte amadivayisi akho.
Isixazululo se-OBS kanye nezilungiselelo ze-FPS ukuze uthole okuningi ku-webcam yakho
Uma ufake i-OBS namuhla futhi wathola ukuthi ikhwalithi yekhamera yewebhu imbi kakhulu, enye yezinto zokuqala okufanele uzihlole izilungiselelo zevidiyo ngaphakathi kohlelo ngokwalo. Ngokuzenzakalelayo, i-OBS ingase yehlise isignali yakho noma isebenzise i-aggressive upscaling ukuze yonge izinsiza; ukuze uqhathanise ezinye izindlela, hlola ukuqhathaniswa kwethuluzi lethu lokuthwebula.
Kuzilungiselelo zomthombo wevidiyo wekhamera yewebhu, khetha inketho yokusetha idivayisi futhi uqiniseke ukuthi ukhetha isixazululo esiphezulu esisekelwa yikhamera yakho (isibonelo, 1920×1080 esimweni seLogitech C920). Uma ikhamera yakho ingu-4K, qinisekisa ukuthi imodi ekhethiwe ihambelana no-3840×2160 noma u-4096×2160, kuye ngemodeli; futhi cabanga ngendlela lokhu okuthinta ngayo uhlobo lwesikrini osithwebula kuso kanye nokukhetha kwakho imonitha yokusebenza.
Ngaphandle kwesisombululo, ozimele ngomzuzwana (i-FPS) bathinta kakhulu ikhwalithi ebonakalayo. I-webcam esebenza ku-30 FPS eqinile ivame ukubukeka ibukhali kuneyo eshintshashintshayo phakathi kwe-15 ne-25 FPS. Ku-OBS, funa inketho ye-FPS yomthombo bese usetha inani elihambisana nalokho okusekelwa yidivayisi yakho, ugweme izindlela ezizenzakalelayo ezishintshayo ngokwezimo zokukhanya.
Hlola futhi izilungiselelo zevidiyo ezijwayelekile ze-OBS (Izilungiselelo > Ividiyo). Lapho uzobona isisekelo (ikhanvasi) kanye nezixazululo zokukhipha. Uma usebenzisa ikhamera yakho ku-1080p, kodwa isisekelo noma isixazululo sokukhipha sisethwe ku-720p, uhlelo luzonciphisa futhi lushintshe usayizi wesithombe , okungenza kube nzima ukufunda umbhalo omncane phansi kwesikrini.
Ekugcineni, hlola isihlungi sokukhulisa izinga. Izilungiselelo ze-OBS zinikeza izinketho ezahlukahlukene (i-Bilinear, i-Bicubic, i-Lanczos, njll.). Ukuze ugcine imininingwane lapho wehlisa izinga lesithombe, ngokuvamile kunconywa ukusebenzisa i-Lanczos noma enye indlela esezingeni eliphezulu , ebushelelezi kancane futhi ilondoloze kangcono imiphetho emincane, efanelekile ekwenzeni umbhalo ubonakale.
Izilungiselelo ezenziwe ngesandla ze-Logitech C920 (kanye nama-webcam afanayo)
I-Logitech C920 iyi-webcam ethandwa kakhulu engenza kahle kakhulu, kodwa izilungiselelo zayo ezizenzakalelayo ngezinye izikhathi zilimaza kakhulu kunokuba zisize. Kuvamile ukuthi i-autofocus ihlale ilungisa, ukuvezwa kungalungiseki kahle endaweni yesehlakalo, noma inzuzo ibe phezulu kakhulu, okudala umsindo kanye nokuntuleka kokucaca.
Ukuze uthole okuningi kukho, kunconywa ukuthi ukhubaze izindlela ezizenzakalelayo ngangokunokwenzeka, kungaba kusuka kuphaneli yokulawula ye-Logitech noma ngezinketho ezithuthukisiwe ku-OBS. Ukulungisa ngesandla amapharamitha afana nokuchayeka, inzuzo, isinxephezelo sokukhanya, kanye nokugxila kungenza umehluko omkhulu ekucaceni okubonakalayo, ikakhulukazi uma umgomo wakho ukukwazi ukufunda umbhalo esikrinini.
Ezinhlelweni eziningi, kungcono ukusetha ukugxila kube ngesandla uma ungeke ushintshe ibanga ukusuka kukhamera. Lokhu kuvimbela ikhamera yewebhu ukuthi "iphefumule" njalo noma ifune ukugxila, okubangela ukufiphala okungazelelwe okonakalisa ubukhali bemininingwane emihle kakhulu.
Ukuvezwa nakho kudinga ukucatshangelwa ngokucophelela. Ukuvezwa okuncane kakhulu kuholela esithombeni esimnyama kakhulu, okuphoqa ikhamera ukuthi isebenzise inzuzo eyengeziwe futhi kubangele umsindo. Ukuvezwa okuningi kakhulu kuphazamisa ama-glances futhi kwenza isofthiwe yokucindezela isebenze kanzima, okuholela ekulahlekelweni kwemininingwane ezindaweni lapho ufuna umbhalo ubonakale khona.
Uma isofthiwe yakho ikuvumela, londoloza iphrofayili enalezi zilungiselelo ezenziwe ngesandla ze-Logitech C920 yakho (noma ikhamera yewebhu oyisebenzisayo), ukuze njalo uma uvula i-OBS noma uhlelo lwekholi yevidiyo, ukwazi ukuthola ukucushwa okuzinzile nokulungiselelwe kahle futhi uvimbele amanani azenzakalelayo ukuthi angasheshi.
Indima yokukhanyisa ekhwalithini yesithombe
Ukukhanya kuyisici esithathwa kancane kakhulu uma kukhulunywa ngokuthuthukisa ikhwalithi ye-webcam, ngisho nasemamodelini e-4K. Ikhamera enenzwa enhle ingakhiqiza isithombe esingesihle uma indawo ingakhanyiswanga kahle. Ukuze ifunde ngokucacile lokho okubonakala phansi kwesikrini, ikhamera idinga ukuthola ukukhanya okufanayo nokwanele.
Ezindaweni ezimnyama, uhlelo luvame ukuvala isikhala ngokwandisa inzuzo. Lokhu kuphumela emsindweni obonakalayo, ukuthungwa okunezinhlayiya, kanye nokulahlekelwa ukucaca okuphelele. Umphumela uba ukuthi umbhalo ubonakala ungacacile futhi imininingwane emincane iyanyamalala. Ngakho-ke, ngaphambi kokusola isinqumo, kufanelekile ukwengeza umthombo wokukhanya othambile wangaphambili (isibani esiyindilinga, isibani esisabalele, njll.) esikhanyisa kahle ubuso bakho nendawo okuzungezile; ezimweni eziningi, izesekeli ezifanele zenza umehluko omkhulu.
Gwema ukukhanya okunamandla okuvela endaweni eyodwa, ikakhulukazi kusuka phezulu noma ngemuva kwakho. Lolu hlobo lokukhanya ludala izithunzi eziqinile kanye nokugqama okweqile, okwenza kube nzima ngekhamera yewebhu kanye nekhodi yokucindezela ukubona ngokunembile imiphetho. Esikhundleni salokho, ukukhanya kwangaphambili, futhi uma kungenzeka, ukukhanya okuthambile eceleni, kusiza inzwa ukuthi ibambe imininingwane enembile kakhulu.
Kunconywa futhi ukusebenzisa isikrini sokuqapha njengomthombo wokukhanya, kodwa hhayi njengowokuqala. Ukukhanya kwesibonisi kungasiza ekukhanyiseni ubuso, kodwa uma kuwukuphela komthombo wokukhanya, ibhalansi emhlophe ingaba yimbi, futhi ikhamera ingase ilungise ukuvezwa kwayo ngendlela engathembekile, okubangela ukushintshashintsha kwesithombe okuzogcina kuphazamise ukufunda kahle.
Ekugcineni, ukutshala imali encane ekukhanyeni (ngisho nangezixazululo ze-DIY eziklanywe kahle) kuvame ukunikeza intuthuko yekhwalithi engcono kunokuzama ukuthola okuningi ngekhamera engenalo ukukhanya. Ikhamera yewebhu engu-1080p ekhanyiswe kahle ivame ukubukeka ingcono kunekhamera okuthiwa i-4K egumbini elimnyama.
Ukubaluleka kwekhebula kanye ne-USB port ekhwalithini
Uma usebenzisa ikhebula le-USB extension, njengoba kuchaziwe, cabanga ngesignali njengamanzi ageleza ngepayipi: uma ikhebula lide futhi libi kakhulu, kulapho amathuba okuthi isignali izokonakala noma incishiswe khona . Ama-webcam amaningi, lapho ethola izinkinga zokuxhumana, anciphisa ikhwalithi noma i-FPS ukuze agweme ukuphazamiseka.
Uma ikhamera yakho yewebhu ikude ne-PC yakho futhi udinga ikhebula lesandiso, qiniseka ukuthi liyikhebula lekhwalithi enhle, okungcono kube elisebenzayo (elinokukhulisa isignali). Amakhebula amade kakhulu ngaphandle kokukhulisa angabangela uhlelo ukuthi lukhawulele ukulungiswa, i-bitrate, noma ngisho nokuzinza kokuxhumeka , futhi lokhu kuzobonakala esithombeni.
Hlola futhi ukuthi iyiphi imbobo kukhompyutha yakho oyixhuma kuyo. Noma nini lapho kungenzeka, sebenzisa imbobo ye-USB eqondile kubhodi lomama (amambobo angemuva ku-PC yedeskithophu, isibonelo) futhi ugweme ama-hub abiwe namanye amadivayisi anamandla amakhulu, njenge-hard drive yangaphandle; futhi ubuyekeze ukuthi yiziphi izinto eziyisisekelo zedeskithophu ozixhume nokuthi zithinta kanjani i-bandwidth.
Uma ungaqiniseki ukuthi ikhebula lesandiso libangela inkinga yini, zama ukuxhuma ikhamera ngqo, ngaphandle kwesandiso, bese uqhathanisa ikhwalithi ku-OBS noma kuhlelo lokusebenza lwekhamera. Uma ubona intuthuko, ikhebula cishe liyingxenye yenkinga. Kuleso simo, shintshela kukhebula elingcono noma uthuthe ikhompyutha noma ikhamera yakho ukuze unciphise ibanga kanye nobunzima bekhebula.
Abanye abasebenzisi bathola nokuthi ama-port angaphambili embhoshongweni wekhompyutha yabo noma ama-port athile e-laptop awanikezi ukusebenza okufanayo nabanye. Unganqikazi ukuzama izixhumi ezahlukene kukhompyutha yakho uze uthole leyo lapho ikhamera yewebhu ihlala izinzile futhi inikeza ikhwalithi enhle.
Lungiselela ukuthwebula kwedeskithophu kanye nekhamera yewebhu ngasikhathi sinye
Uma umgomo wakho uwukuqopha ividiyo ye-YouTube ebonisa lokho okwenzayo esikrinini ngenkathi uvela ngekhamera ngesikhathi esifanayo nekhamera yakho yewebhu, kunezinto eziningana ezidingekayo. Akuyona nje ikhwalithi yewebhu yewebhu ebalulekile, kodwa futhi nendlela ohlanganisa ngayo imithombo yevidiyo ngaphakathi kwe-OBS noma kunoma iyiphi isofthiwe oyisebenzisayo.
Uma ufuna ukuqinisekisa ukuthi ulwazi oluncane olungezansi kwesikrini, njengombhalo ovela ohlelweni, iwebhusayithi, noma umdlalo, luyafundeka, udinga ukuqaphela ngesinqumo othwebula ngaso ideskithophu yakho. Uma i-monitor yakho ikhipha i-1080p bese unciphisa isinqumo sevidiyo yokugcina ukuze wonge isikhala, uzobe ubeka engcupheni ukufundeka kwalezo zinto ezincane . Futhi, khumbula umehluko wobuchwepheshe phakathi kokuxhumana uma usebenzisa izibonisi zangaphandle.
Umkhuba omuhle ukunquma kusukela ekuqaleni ukuthi uzosebenzisa siphi isinqumo kuvidiyo yokugcina (isibonelo, i-1080p) bese uqinisekisa ukuthi kokubili isithombe-skrini kanye nokuphakelwa kwewebhu kuthathwa kuleso sinqumo sendabuko. Ngale ndlela, ugwema ukukala kabili okungadingekile okuphetha ngokwenza umbhalo ube bushelelezi ngokweqile.
Ngaphezu kwalokho, ungalungisa usayizi wefasitela le-webcam. Uma ikhamera ithatha indawo enkulu kakhulu esikrinini, ungase ufihle olunye ulwazi ofuna umbukeli alubone. Uma ulwenza lube luncane kakhulu, noma ngabe isignali isezingeni eliphezulu, luzocindezelwa uma lufakwa ku-canvas , okunciphisa kakhulu imininingwane ebonwayo.
Hlela ukwakheka kwesigcawu sakho: cabanga ngokuthi uzosibeka kuphi isithombe sakho, ukuthi yiziphi izingxenye zesikrini ezibalulekile ukuzifunda, bese ulungisa ubukhulu ukuze konke kucace. Futhi, vele, sebenzisa i-bitrate yokuqopha ephezulu ngokwanele (noma i-bitrate yokusakaza, uma ubukhoma); uma ucindezela ividiyo kakhulu, ukucindezela kwe-YouTube noma amanye amapulatifomu kuzolimaza kakhulu ubukhali bombhalo omncane.
Amapharamitha okucindezela kanye ne-bitrate uma uqopha noma usakaza
I-codec kanye ne-bitrate oyikhethayo yokurekhoda noma ukusakaza kungashintsha isithombe esihlanzekile sibe yinto egcwele izinto zakudala. Ngisho noma konke kubukeka kuphelele kukhamera, uma i-bitrate iphansi kakhulu, imininingwane emincane, njengombhalo ongezansi kwevidiyo, izobonakala ifiphele futhi ivimbekile.
Ku-OBS, uma uhlela umphumela (ukurekhoda noma ukusakaza), qiniseka ukuthi ukhetha i-bitrate efanelekile yesisombululo osisebenzisayo. Ku-1080p, ngokuvamile kuyalulekwa ukusebenzisa i-bitrate ephezulu uma ufuna umbhalo ufundeke kalula, ikakhulukazi lapho kunokunyakaza okuningi esikrinini noma izinguquko zesimo esisheshayo.
Uhlobo lokufaka ikhodi (x264, NVENC, njll.) nalo lubalulekile. Akuwona wonke ama-encoding asebenza kahle ngokulinganayo kuma-bitrate aphansi. Uma i-PC yakho ivumela lokho, beka phambili ikhwalithi kunokunciphisa usayizi wefayela ngokweqile, okungenani lapho ukukhulisa ukufundwa nokucaca kwesithombe kuyinto eza kuqala kuwe.
Ungakhohlwa ukuthi uma ulayisha ividiyo ku-YouTube, ipulatifomu izosebenzisa ukucindezela kwayo. Lokhu kusho ukuthi udinga ifayela lomthombo olilayishayo libe sezingeni eliphezulu kakhulu, ukuze ukucindezela kokugcina kungalimazi ngokuphelele imininingwane emincane. Ngamafuphi, i-bitrate ephansi kakhulu kufayela lomthombo isho ukulahlekelwa okuphindwe kabili uma i-YouTube iyicindezela kabusha . Ukuze uhlele futhi ulungise okokugcina, ungabheka izinketho zesofthiwe nabahleli abagcina ikhwalithi.
Amaphutha avamile awonakalisa ikhwalithi yewebhu
Kunezinkinga eziningi ezivamile, lapho zihlanganiswa, ezichaza ukuthi kungani ikhamera enhle ngokwemfundiso, njengeLogitech C920, igcina iletha ikhwalithi edumazayo. Ukuzibona kusiza ukugwema ukukhungatheka nokuchitha isikhathi ulungisa izilungiselelo ngokungadingekile.
Elinye lamaphutha avame kakhulu ukuthembela ngokungazi lutho kuzilungiselelo ezizenzakalelayo ze-webcam. Lezi zindlela zizama ukuzivumelanisa nazo zonke izinhlobo zezindawo, kodwa azivamile ukwenza kahle ezimweni ezithile zokuqopha i-YouTube, ukusakaza, noma ukuthwebula ideskithophu. Phela, ikhamera ayazi ukuthi yini ebalulekile endaweni yakho noma ukuthi yini okudingeka uyibone ibukhali.
Elinye iphutha elivamile ukwehluleka ukuhlola isinqumo sangempela sekhamera ngaphakathi kohlelo lokusebenza. Ngezinye izikhathi, noma ngabe ikhamera isekela i-1080p noma i-4K, uhlelo luyisebenzisa ku-720p noma ngaphansi, kungaba ngenxa yokulungiselelwa okungalungile noma imikhawulo ye-bandwidth. Lokhu kunciphisa kakhulu ikhono lokufunda imininingwane emincane kuvidiyo.
Ukubaluleka kokuhlola inhlanganisela ehlukene ye-USB port, ikhebula, kanye nokucushwa nakho kuvame ukunganakwa. Abasebenzisi abaningi banamathela ekucushweni kokuqala okusebenzayo, noma ngabe akwanele, futhi abazami, isibonelo, ukuxhuma i-webcam ngqo kwi-PC ngaphandle kwekhebula lokunweba ukuze babone ukuthi intuthuko yekhwalithi iyabonakala yini.
Okokugcina, kulula ukukhohlwa ukuthi ushintsho ngalunye olwenzayo endaweni yesehlakalo (ukwengeza ama-overlays, ama-animation, izihlungi, njll.) lungenza kube nzima ukucindezelwa kwamavidiyo, kokubili ku-OBS kanye nakamuva ku-YouTube noma kwamanye amapulatifomu. Uma okuqukethwe kuyinkimbinkimbi kakhulu, imininingwane iyahlupheka kakhulu. Ngezinye izikhathi, ukwenza lula indawo yesehlakalo nokubeka phambili umklamo ohlanzekile onokufundeka kahle kuyindlela engcono kakhulu yokuthuthukisa ikhwalithi ebonakalayo.
Uma kukhulunywa ngokuthola okuningi ku-webcam yakho ye-1080p noma ye-4K, konke kuncike ekuqondeni ukuthi ikhamera, izintambo, i-USB port, i-Windows 10, i-OBS, kanye nokukhanya kusebenzelana kanjani. Ukulungisa amapharamitha ayisihluthulelo e-Logitech C920 ngesandla, ukuqinisekisa ukukhanya okufanele, ukusebenzisa izintambo nama-port athembekile, ukulungisa kahle isixazululo kanye ne-FPS kusofthiwe, nokukhetha i-bitrate yokuqopha efanele yizinyathelo ezenza umehluko ngempela. Njengoba lezi zinto zilawulwa, ikhwalithi isuka ekubeni "embi" iye kwenele ukuqopha amavidiyo e-YouTube esikrinini esigcwele, ukukhombisa lokho okwenzayo kusikrini sakho, futhi, okubaluleke kakhulu, ukuqinisekisa ukuthi ulwazi oluboniswe phansi kwevidiyo lufundeka kahle ngaphandle kokushintsha amakhamera.
