Iisetingi ezingcono zoFakelo lweYouTube

Ukuqonda iiMfuno zoFakelo lweVidiyo zeYouTube

I-YouTube ixhasa iindidi ngeendidi zeefomati zevidiyo, kodwa ayizizo zonke iifomati ezenziwe zilingana xa kuziwa ekulayisheni umgangatho kunye nesantya sokucubungula. Iqonga licebisa ngokusemthethweni iifayile zeMP4 kunye ne-codec yevidiyo ye-H.264 kunye ne-codec yomsindo we-AAC ukuze ufumane iziphumo ezilungileyo. Olu luhlu lubonelela ngeyona ndlela ilungileyo yobungakanani befayile, umgangatho, kunye nokuhambelana kuzo zonke izixhobo kunye nezikhangeli. Ngelixa uYouTube esamkela iifomati ezifana ne-MOV, AVI, WMV, FLV, kunye neWebM, ukufakwa kwezi fomati kuhlala kukhokelela kumaxesha amade okuqhuba kunye nokuthotywa komgangatho ngexesha lenkqubo yokuguqula kaYouTube. Iqonga lidibanisa ngokuzenzekelayo zonke iividiyo ezilayishiweyo kwizisombululo ezininzi kunye neefomathi zokusasazwa, kodwa ukuqala ngefomathi ecetyiswayo kuqinisekisa isiphumo esihle kakhulu. Ukuqonda ezi mfuno zobugcisa kubalulekile kubadali bomxholo abafuna iividiyo zabo zibukeke zinobuchule kwaye zilayishe ngokukhawuleza kubabukeli.

• IMP4 enekhowudi ye-H.264 yifomati ekhethwa nguYouTube
• Ubukhulu bobungakanani bobungakanani befayile bungama-256GB okanye iiyure ezili-12 ubude
• Iireyithi zesakhelo ezixhaswayo ziquka i-24, 25, 30, 48, 50, kunye ne-60 FPS.

Isisombululo seVidiyo esiLungileyo kunye noSeto lweBitrate

Isisombululo sevidiyo kunye nomsebenzi we-bitrate ngesandla-ngesandla ukumisela umgangatho wokubonwayo wokulayisha kwakho kunye nobukhulu befayile. Kuluhlu lwe-1080p, i-YouTube icebisa ibitrate phakathi kwe-8-12 Mbps kumazinga asezantsi efreyimu kunye ne-12-18 Mbps kumxholo wefreyimu ephezulu (50/60fps). I-bitrate ephezulu igcina iinkcukacha ezithe kratya kwaye inciphisa ubugcisa bezinto zakudala, kodwa ikwakhokelela kubungakanani beefayile ezinkulu kunye namaxesha okulayisha amade. Xa ukhetha isisombululo, qwalasela umthombo wakho womxholo kunye nabaphulaphuli. Ngelixa i-4K (2160p) inika ukucaca okumangalisayo, ifuna i-bitrate ephezulu kakhulu (35-45 Mbps) kunye namaxesha okucubungula amade. Abadali abaninzi bafumanisa ukuba i-1080p inika indawo emnandi phakathi komgangatho kunye nokusebenza. Kukwabalulekile ukuthelekisa isisombululo sakho sokulayisha kwisisombululo sakho sokurekhodwa-ukunyusa umgangatho wevidiyo esezantsi ayiphuculi umgangatho kwaye ihlala ingenisa izinto zakudala ezingafunwayo. Ukufumana ezona ziphumo, sebenzisa i-variable bitrate (VBR) encoding kune-bitrate engaguqukiyo (CBR). I-VBR yabela amasuntswana amaninzi kwimiboniso entsonkothileyo enentshukumo eninzi okanye iinkcukacha ngelixa usebenzisa amasuntswana ambalwa kwimiboniso elula, ekhokelela kumgangatho ongcono xa uwonke kwiisayizi zefayile ezincinci.

Uqwalaselo lweAudiyo kwiziphumo zobuNgcali

Umgangatho womsindo uhlala ungahoywa kodwa udlala indima ebalulekileyo ekuzibandakanyeni nasekugcinweni kombukeli. UYouTube ucebisa ikhowudi yomsindo ye-AAC enesampulu yesampulu ye-48kHz kunye nebitrate ye-384 kbps yomsindo westereo. Ezi zicwangciso zibonelela ngokuveliswa komsindo ngekristale ngelixa ugcina ubungakanani beefayile ezifanelekileyo. Kuphephe ukusebenzisa ii-bitrate ezisezantsi njenge-128 kbps, njengoko zinokuzisa ucinezelo olubonakalayo olwenziwayo oluphazamisa amava okubukela. Kubenzi bomxholo abasebenzisa iingoma ezininzi zeaudiyo, ezinjengomculo owahlukileyo kunye nokurekhodwa kwelizwi, kubalulekile ukulungelelanisa ngokufanelekileyo amanqanaba phambi kokulayisha. Ukusetyenzwa kweaudio yeYouTube ngamanye amaxesha kunokukhulisa ukungalingani okukhoyo, ukwenza ukuxubana okungalunganga kubonakale ngakumbi. Qinisekisa ukuba amanqanaba eaudio akho aphezulu malunga ne-6dB ukuya kwi-3dB, ushiya i-headroom kwi-YouTube ngelixa uphepha ukugqwetheka. Amanqanaba eaudio angaguqukiyo kuyo yonke ividiyo yakho nawo aphucula amava ababukeli kwaye anciphise ukubakho kwababukeli ukulungelelanisa umthamo wabo rhoqo.

Isantya seSakhelo kunye noSeto lweMotion

Ireyithi yesakhelo ichaphazela kakhulu amava okubukela kunye nobukhulu befayile yokulayishwa kwakho kuYouTube. Umxholo oqhelekileyo ngokuqhelekileyo usebenzisa i-24fps (i-cinematic), i-25fps (imimandla ye-PAL), okanye i-30fps (umgangatho wokusasazwa), ngelixa umdlalo kunye nomxholo ohambayo ophezulu uhlala uzuza kwi-60fps ukuze udlale kakuhle. Umgaqo ongundoqo kukutshatisa ireyithi yesakhelo sokulayisha kwisixhobo sakho somthombo – kunqande ukuguqulwa kwesantya sesakhelo xa kunokwenzeka njengoko kunokwazisa ukuthintitha okanye ukufiphala kwentshukumo. Ngomxholo wezinga eliphezulu lesakhelo, qinisekisa ukuba ibitrate yakho iphezulu ngokwaneleyo ukuze ulawule ulwazi olongezelelekileyo lwexeshana. Ividiyo ye-60fps ifuna malunga ne-1.5x yebitrate yomxholo olinganayo we-30fps ukugcina umgangatho ofanayo. Ukongezelela, qwalasela imikhwa nezixhobo zokubukela zabaphulaphuli bakho. Ngelixa i-60fps ibonelela ngentshukumo egudileyo, ifuna i-bandwidth ethe kratya kunye namandla okusebenza, asenokungalungelanga ababukeli kunxibelelwano olucothayo okanye izixhobo ezindala. Xa ufaka ikhowudi yesiqulatho esishukumayo esinzima njengeevidiyo zokudlala okanye umfanekiso oshukumayo wezemidlalo, sebenzisa useto olufanelekileyo loqikelelo lwentshukumo kwi-encoder yakho. Ii-algorithms zoqikelelo oluphezulu lwentshukumo zinokuphucula kakhulu inkangeleko yezinto ezihamba ngokukhawuleza kunye nokunciphisa izinto zakudala, nangona zinyusa ixesha lokufaka iikhowudi.

Isithuba soMbala kunye neNgqwalaselo yoLuhlu oluDynamic

Indawo yombala kunye nesetingi zoluhlu oluguquguqukayo luchaphazela indlela iividiyo zakho ezibonakala ngayo kwizixhobo ezahlukeneyo kunye neziboniso. I-YouTube iyayixhasa yomibini imigangatho yomgangatho oguquguqukayo (SDR) kunye noluhlu oluphezulu lokuguquguquka (HDR), kodwa uninzi lwababukeli basabukele kwimiboniso ye-SDR. Ngomxholo we-SDR, sebenzisa iRec. 709 indawo yombala (ekwaziwa ngokuba yi-sRGB) enoluhlu olulinganiselweyo (16-235) kwimibala ekhuselekileyo yosasazo eboniswa rhoqo kuzo zonke izixhobo. Umxholo we-HDR unikezela ngombala owandisiweyo we-gamut kunye noluhlu lokuqaqamba kodwa lufuna iiparamitha ezithile zekhowudi kunye nezixhobo zokujonga ezihambelanayo. Ukuba ulayisha umxholo we-HDR, sebenzisa iRec. Indawo yombala we-2020 kunye ne-PQ (i-Perceptual Quantizer) okanye i-HLG (i-Hybrid Log-Gamma) imisebenzi yokudlulisa. Nangona kunjalo, qinisekisa ukuba umxholo wakho ubanjiwe okanye wenziwa kwi-HDR – ukuphawula nje umxholo we-SDR njengoko i-HDR iya kubangela imibala ehlanjiweyo kunye namava okujonga kakubi. Ukuchaneka kombala, hlala usebenza kwindawo elungelelanisiweyo kwaye uthumele ngaphandle usebenzisa indawo yombala efanayo neprojekthi yakho. Kuphephe ukuguqulwa kwendawo yombala ngokuzenzekelayo, njengoko inokutshintsha imibala ngokungalindelekanga. Ukuba awuqinisekanga malunga noseto lombala, namathela kuRec. I-709 / sRGB, eqinisekisa ukudlala ngokuqhubekayo kulo lonke uluhlu olubanzi lwezixhobo kunye neemeko zokubukela.

ULungiselelo lweFayile kunye nokuPhunyezwa kokuLayishwa

Ukulungiswa kwefayile ngokufanelekileyo kunokunciphisa kakhulu amaxesha okulayisha kunye nokulibaziseka kokucubungula. Ngaphambi kokulayisha, qinisekisa ukuba ifayile yakho yevidiyo ifomathiwe ngokufanelekileyo kwaye yenziwe kakuhle. Sebenzisa iskena esiqhubekayo kunevidiyo edityanisiweyo, njengoko umxholo odityanisiweyo unokubangela ukuhlanganisa izinto zakudala kwimiboniso yanamhlanje. Ukongeza, beka i-atom ye-moov ekuqaleni kweefayile zeMP4 (ekwabizwa ngokuba ‘yi-web optimization’ okanye ‘isiqalo esikhawulezayo’) ukuvumela ukhuphelo oluqhubela phambili kunye nokudlala kwakhona okukhawulezileyo. Qwalasela uqhagamshelo lwakho lwe-intanethi kunye neshedyuli yokulayisha xa ulungiselela iifayile. Iifayile ezinkulu ze-4K zinokuthatha iiyure ukulayishwa kunxibelelwano olucothayo, kwaye umgca wokusetyenzwa kweYouTube unokongeza ulibaziseko olongezelelekileyo ngamaxesha aphakamileyo. Ngomxholo obuthathaka ngexesha, ukulayisha ngexesha leeyure ezingasebenziyo (ngokuqhelekileyo ebusuku kakhulu okanye ekuseni kakhulu kwingingqi yakho) zihlala zikhokelela ekusebenzeni ngokukhawuleza. Ungaphinda ulayishe iividiyo ezingadweliswanga okanye zabucala kuqala ukuze ugqibezele ukusetyenzwa phambi kokuba uzenze esidlangalaleni. Ukubizwa kwefayile kunye nentlangano yemethadatha ihlala ingahoywa kodwa imiba ebalulekileyo yenkqubo yokulayisha. Sebenzisa amagama eefayile ezichazayo kwaye uqinisekise ukuba umhleli wakho wevidiyo uthumela ngaphandle imethadatha ecocekileyo. Enye isoftware yokuhlela ibandakanya imethadatha engeyomfuneko enokunyusa ubungakanani beefayile okanye ibangele imiba yokusetyenzwa. Ukuba ne-thumbnail yakho, isihloko, inkcazo, kunye neethegi zilungile ngaphambi kokuba ulayishe kwakhona kulungelelanisa inkqubo yokupapasha.
