Indlela yokulungisa ikhwalithi yevidiyo uma uthumela izethulo ze-PowerPoint

Lapho kufika isikhathi Dala isethulo sevidiyo se-PowerPointKulula ukudideka ngezinqumo, i-1080p, i-4K, i-bitrate, amafomethi, kanye namanye amagama obuchwepheshe. Ngaphezu kwalokho, i-PowerPoint inemikhawulo yayo kanye nezilungiselelo ezifihliwe ezingathinta kakhulu ubukhali bomphumela wokugcina, kungakhathaliseki ukuthi uthumela isethulo njengevidiyo noma ulondoloza amaslayidi ngamanye njengezithombe.

Uma ufuna isethulo sakho sibukeke kuhlanzeke ngangokunokwenzeka ezikrinini ezinkulu, kumaphrojektha noma ezinkundleni zokuxhumanaUdinga ukuqonda ukuthi i-PowerPoint yenzani ngempela lapho ithumela kwamanye amazwe, ukuthi ungayikhulisa kanjani kusukela ku-720p kuya ku-1080p noma ku-4K, ukuthi i-bitrate iyini indima edlalwa yiyo, nokuthi ungayilungisa kanjani irejista ye-Windows ukuze uthole izithombe zesilayidi ngesisombululo esiphezulu ngaphandle kokulahlekelwa ikhwalithi endleleni.

Izinketho zokuthumela ividiyo ze-PowerPoint: 4K, 1080p, 720p, kanye ne-480p

Ezinguqulweni zesimanje ze-PowerPoint (2016, 2019, 2021 kanye I-Microsoft 365) kungaba Guqula isethulo sakho ngqo sibe ifayela levidiyo ngaphandle kokusebenzisa izinhlelo zangaphandle, yize kunezinhlelo zokuthuthukisa ikhwalithi yevidiyookuyinto elula kakhulu uma usuvele unazo zonke izinto eziqukethwe kanye nezithombe ezinyakazayo ezilungisiwe.

Ukuze wenze lokhu, udinga nje ukuya Ifayela > Thumela > Dala ividiyoKusukela kulelo phaneli, i-PowerPoint ikuvumela ukuthi ukhethe phakathi kwezimfanelo eziningana ezichazwe ngaphambilini ezithinta kokubili isinqumo kanye nosayizi wefayela lokugcina.

Izinketho ezine eziyinhloko Izinketho zekhwalithi yevidiyo ku-PowerPoint zimi kanje, ngayinye inesisombululo sayo esilinganiselwe kanye nomphumela kusayizi wefayela:

• I-Ultra HD (4K): ikhiqiza ividiyo ye Amaphikseli we-3840 x 2160, enosayizi wefayela omkhulu kakhulu kanye nekhwalithi ephezulu kakhulu, ilungele amaphrojektha angu-4K noma izikrini ezinkulu.
• I-HD ephelele (1080p): kudala ifayela Amaphikseli we-1920 x 1080, enosayizi omkhulu wamafayela kanye nekhwalithi ephezulu, ilungele amaphrojektha amaningi esimanje kanye nokulayisha kumapulatifomu aku-inthanethi.
• I-HD (720p): khiqiza ividiyo Amaphikseli we-1280 x 720Njengoba inosayizi ophakathi kanye nekhwalithi eyamukelekayo, iwusizo uma ufuna ukonga isikhala noma lapho imishini ilinganiselwe kakhulu.
• Okujwayelekile (480p): yehlisa isinqumo sibe Amaphikseli we-852 x 480, ikhiqiza ifayela elilula kakhulu elinekhwalithi ephansi kakhulu, elinconywa kuphela ukusetshenziswa okulula kakhulu noma izikrini ezincane.

Uma usukhethe ikhwalithi, i-PowerPoint ikuvumela nquma ukuthi uzosebenzisa izikhawu eziqoshiwe kanye nokulandisa noma cha. Ungafaka el tiempo lokho okuchazile kuslayidi ngasinye, amanothi okulandisa noma ukuqoshwa kwesikrini uma uke wakudala ngaphakathi kohlelo ngokwalo.

Ebhokisini lika Ubude ngemizuzwana yesilayidi ngasinye Ungasetha isikhathi esinqunyiwe samaslayidi angenazo izikhawu ezichaziwe. Leli nani lizosetshenziswa njengobude obujwayelekile bokuqhubekela phambili ngokuzenzakalelayo kusilayidi esilandelayo ngesikhathi sokudalwa kwevidiyo.

Uma konke sekumi ngomumo, cindezela Dala ividiyoUkhetha ifolda, uthayiphe igama lefayela, bese ukhetha ifomethi yokuphuma, okuvame ukuba yi-PowerPoint MPEG-4 (.mp4) o IWindows Media Video (.wmv)Zombili ziyahambisana nabadlali abaningi, futhi uma udinga ukuguqula lawo mafayela ungasebenzisa I-VLC yokuguqula nokuhlela amavidiyo.

Ngemva kokuqinisekisa nge GcinaI-PowerPoint iqala uku dala ividiyo ngemuvaUsengabona ibha yokuqhubeka phansi kwewindi le-PowerPoint, futhi kuye ngobude besethulo, inani lezithombe ezinyakazayo, kanye nekhwalithi ekhethiwe (ikakhulukazi ku-4K), inqubo ingathatha noma yikuphi kusukela kumasekhondi ambalwa kuya kwemizuzu embalwa.

Usayizi wesilayidi uthinta kanjani ukucaca kwevidiyo?

Umbuzo ovame kakhulu ukuthi, kufanele yini ividiyo itholakale ku- 1920 x 1080 Kuhle kakhulu, sidinga ukudala amaslayidi anosayizi okhethekile ngamasentimitha, isibonelo ngokushintsha usayizi ojwayelekile ongu-13,33 x 7,5 ube ngelinye inani elifana namasentimitha angu-20 x 11,25.

I-PowerPoint, ngokuzenzakalelayo, idala izethulo ezintsha nge Amaslayidi e-panoramic angu-13,33 x 7,5 intshiLokhu kuvame ukuhlotshaniswa nesinqumo samaphikseli angu-1280 x 720 (720p) uma kuthunyelwa njengesithombe, kodwa lobo buhlobo abusebenzi ngendlela efanayo uma sikhuluma ngevidiyo noma ihluzo zevektha.

Isihluthulelo lapha ukuqonda ukuthi iningi lezinto ozidweba ku-PowerPoint (izimo, amabhokisi ombhalo, amashadi, njll.) izinto ze-vectorNgamanye amazwi, azigcinwa njenge-bitmap engaguquki, kodwa njengemigqa nama-curve angalinganiswa abe yizinqumo eziphakeme ngaphandle kokulahlekelwa ubukhali. Ngakho-ke, noma usayizi wesilayidi ozenzakalelayo ubonakala "ungu-720p", empeleni ungathunyelwa ku-1080p noma ku-4K ngaphandle kokuqukethwe kwe-vector okubonakala kufiphele.

Lokhu kusho ukuthi uma ikhompyutha yevidiyo noma iphrojektha ikhipha isignali ku- 1920 x 1080, I-Power Point shintsha isilayidi sibe yileso sinqumoOkuqukethwe kwevektha kwenziwa ngokushesha ngobukhali obukhulu ngangokunokwenzeka, futhi uzobona kuphela ukulahleka kwekhwalithi ezithombeni ezi-raster (izithombe, ama-logo anesinqumo esiphansi, njll.), ezincike kumaphikseli okuqala.

Ngamanye amazwi, ngesethulo esijwayelekile esinobunjwa nombhalo, Akubalulekile ukushintsha ubukhulu besilayidi Ukuze ibukeke kahle ku-1080p. Okubalulekile ukuthi izithombe ozifakayo zinesisombululo esanele sokumelana nalolo sayizi ngaphandle kokushintshashintsha kwamaphikseli.

Thumela amaslayidi njengezithombe ezinesinqumo esiphezulu ngokushintsha iRegistry

Uma esikhundleni sokuthumela isethulo njengevidiyo oyifunayo londoloza islayidi esithile njengesithombe (ukuze isetshenziswe kumanethiwekhi, ekuklanyweni kwezithombe noma njengohlaka olunganyakazi), i-PowerPoint isebenzisa isixazululo esizenzakalelayo, ezimweni eziningi, esingaphumeleli.

Ngokuzenzakalelayo, isinqumo sokuthumela isilayidi esilondolozwe njengesithombe sivame ukuba 96 dpi (amachashazi nge-intshi ngayinye)Lokhu kuphumela kumafayela angaba amaphikseli angu-960 x 720 noma angu-1280 x 720, kuye ngokuhlelwa kwesilayidi (okujwayelekile noma isikrini esibanzi). Ngomsebenzi wobungcweti noma ukuphrinta, leli khwalithi lingase linganele ngokusobala.

Ku-Windows, kukhona ithuba lokuthi phoqelela i-PowerPoint ukuthi ithumele ngesisombululo esiphezulu ngokushintsha okufakiwe kweRegistry okubizwa ngokuthi i-ExportBitmapResolution. Kuyilungiselelo elithuthukisiwe, kodwa liwusizo kakhulu uma udinga izithombe zesilayidi ezinesisombululo esiphezulu kakhulu.

Ngaphambi kokuthinta iRejista, kuyalulekwa Vala zonke izinhlelo ezisekelwe ku-Windows Futhi, kungcono, wenze ikhophi yasenqolobaneni yeRegistry uqobo noma okungenani ukhiye ozowuhlela, ngoba noma yiziphi izinguquko ezingalungile zingabangela ukuziphatha okungajwayelekile ohlelweni.

Izinyathelo zokwandisa isinqumo sokuthumela amaslayidi zimi kanje:

1. Vala zonke izinhlelo zokusebenza ivulekile, ikakhulukazi i-PowerPoint nezinye izinhlelo ze-Office.
2. Chofoza ngakwesokudla inkinobho Inicio bese ukhetha Gijima (e Windows 7Iya ku-Qala bese u-Run).
3. Kuhlaka Vula, kubhala regedit bese uchofoza ku ukwamukela ukuvula i-Registry Editor.
4. Zulazula esihlahleni uze uthole ukhiye we-PowerPoint ohambisana nenguqulo yakho. Izindlela ezivame kakhulu yilezi:
   HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\PowerPoint\Options (I-PowerPoint 2016, 2019, i-Microsoft 365)
   HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\PowerPoint\Options (I-PowerPoint 2013)

   HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\PowerPoint\Options (I-PowerPoint 2003)
5. Ngaphakathi kwaleso sihluthulelo, chofoza ku- Izinketho nakwimenyu Hlela, Khetha Inani elisha> le-DWORD (ama-32 bits).
6. Bhala igama lenani elisha I-ExportBitmapResolution bese ucindezela u-Enter ukuze uqinisekise.
7. Bheka lokho I-ExportBitmapResolution Kugqanyisiwe, bese uchofoza kukho. Shintsha kumenyu ethi Hlela.
8. Ewindini le Hlela inani le-DWORD, hlola inketho I-Decimal ukufaka inani kumodi yedesimali hhayi ku-hexadecimal.
9. Ensimini Idatha yenaniFaka inombolo emele isixazululo ofuna ukusisebenzisa, isibonelo 300 Ku-300 dpi. I-Microsoft inikeza ithebula lesiqondiso elinokulingana kwamaphikseli okulinganiselwa:

Ngemva kokufaka inani olifunayo, cindezela ukwamukela Ukuze ulondoloze izilungiselelo, vala i-Registry Editor kusuka kumenyu. Ifayela > Phuma bese uvula kabusha i-PowerPoint ukuze ushintsho luqale ukusebenza.

Londoloza islayidi njengesithombe ngesisombululo esisha

Uma inani leRegistry selishintshiwe, njalo uma ulondoloza islayidi njengesithombe, i-PowerPoint izosebenzisa isinqumo esisha osichazile, ikhiqiza amafayela amakhulu kakhulu futhi abukhali kunangenani elizenzakalelayo.

Ukuze uthumele isilayidi esithile, vula isethulo sakho se-PowerPoint bese uya ku- islayidi ofuna ukusiguqula sibe isithombeKungakhathaliseki ukuthi kuyikhava, isithombe esiyinkimbinkimbi, noma ukwakheka ozokusebenzisa kabusha kwamanye amaphrojekthi.

Ukusuka lapho, hamba uye Ifayela> Gcina Njenge bese ukhetha ifolda lapho ufuna ukugcina khona ifayela. Kumenyu eyehlayo ye- Londoloza njengohlobo Khetha ifomethi yesithombe efanelana kahle nenhloso yakho.

I-PowerPoint inikeza amafomethi amaningana avamile, ngalinye linezinzuzo nezinkinga zalo. Ngokuvamile, lawa afaneleka kakhulu ngokwekhwalithi kanye nokuhambisana:

• I-JPEG (.jpg)Ukucindezela okulahlekelwayo, okulungele izithombe nama-slideshows anezithombe, kuthatha isikhala esincane kakhulu, kodwa akulungile uma udinga ubukhali obukhulu bombhalo.
• I-PNG (.png): ukucindezela okungenakulahlekelwa, kunconywa kakhulu ihluzo ezinombhalo nezizinda eziyisicabangoba igcina imiphetho ihlanzekile futhi ivumela ukucaca.
• I-GIF (.gif): yenzelwe ihluzo ezilula ezinemibala embalwa, ayisetshenziswa kakhulu namuhla ukuthumela amaslayidi asezingeni eliphezulu kwamanye amazwe.
• I-TIFF (.tif): ifomethi enzima kakhulu kodwa enekhwalithi ephezulu, ewusizo emisebenzini ehilela ukuphrinta kobungcweti.
• I-BMP (.bmp): i-bitmap engacindezelwanga, amafayela amakhulu futhi angasebenzi ngaphandle kwasezimweni ezithile kakhulu.
• I-WMF/EMFAmafomethi e-metafile e-Windows, afaneleka uma ufuna ukugcina ikhono elithile le-vector kwezinye izinhlelo ku-ecosystem ye-Windows.

Uma ucindezela GcinaI-PowerPoint izokubuza ukuthi ufuna yini ukuthumela ngaphandle wonke amaslayidi noma amanje njeKhetha inketho ethi "Isilayidi Samanje Kuphela" uma ufuna isithombe esisodwa, esizogcinwa endaweni ecacisiwe kusetshenziswa isixazululo esenziwe ngokwezifiso osichazile nge-ExportBitmapResolution. Uma kamuva ufuna ukuhlanganisa izithombe eziningi ukudala ividiyo, ungakwenza Dala amavidiyo avela ezithombeni nge-FFmpeg.

Uma ufuna ukuhlola ukuthi ikhwalithi entsha isetshenzisiwe ngempela, ungachofoza kwesokudla kufayela lesithombe ku-Explorer, ukhethe Ama-propiedades bese uhlola isixazululo sephikseli namachashazi nge-intshi ngayinye akhiqizwa ngesikhathi sokuthumela kuthebhu yemininingwane.

Imikhawulo yesisombululo esiphezulu uma uthumela kusuka ku-PowerPoint

Nakuba icebo le-Registry linamandla kakhulu, kubalulekile ukukhumbula ukuthi I-PowerPoint ayinamkhawulo ngokwezinga lokuxazululwa.Kunemingcele yangaphakathi, ikakhulukazi ezinguqulweni ezindala, okufanele uyiqaphele ukuze ugweme ukumangala lapho uzama amanani aphezulu kakhulu.

Ezinguqulweni zanamuhla ezifana I-PowerPoint 2013, 2016, 2019 kanye ne-Microsoft 365Akukho mkhawulo oqinile wamachashazi nge-intshi ngayinye, kodwa kunomkhawulo ku- inani lamaphikseli ukuthi i-bitmap ethunyelwe ingaba nalokhu: kuze kufike ku- Amaphikseli ayizigidi eziyi-100.000.000 (ububanzi x ukuphakama).

Lokhu kusho ukuthi, nge-slide ejwayelekile ye-panoramic 13,3 x 7,5 amayintshiInani eliphezulu le-dpi elisebenzisekayo liseduze awu 1000dpiNgoba uma ungayandisa kakhulu, umkhiqizo wobubanzi nokuphakama ngamaphikseli uzodlula umkhawulo wezigidi eziyi-100, futhi i-PowerPoint ngeke isakwazi ukukhiqiza ifayela ngendlela efanele.

Ngokuphambene nalokho, kumaslayidi efomethi yangaphambilini (10 x 7,5 amayintshi, isilinganiso se-aspect esingu-4:3) indawo ephezulu kakhulu esebenzayo inkulu kancane, cishe awu 1155dpiNjengoba indawo ngamasentimitha ihlukile futhi ukubalwa kwamaphikseli aphelele kuyashintsha, umkhawulo womhlaba wonke obekwe uhlelo uhlala ugcinwa.

Ezinguqulweni ezindala, njenge I-PowerPoint 2010 nangaphambilini, umkhawulo uqinile: isinqumo esiphezulu sokuthumela ngaphandle sisethwe ku- Amaphikseli angu-3072 ohlangothini olude kakhulu lwesilayidiLokhu kusho ukuthi, kungakhathaliseki ukuthi ukhulisa kangakanani inani le-ExportBitmapResolution, uma udlula lowo mkhawulo, i-PowerPoint izoyinciphisa ngokuzenzakalelayo ibe usayizi osekelwayo ophezulu.

Isibonelo, ngesilayidi sendabuko se- 10 x 7,5 amayintshi, inani eliphezulu le-ppp elisebenzisekayo licishe libe awu 307dpiUma uphinda ama-intshi ayi-10 ngo-307, uthola amaphikseli angu-3070, angena ngaphakathi komkhawulo we-3072. Noma yikuphi ukulungiselelwa kwe-DPI okuphezulu kuzoncishiswa kube yilobo bude bephikseli engu-3072 ekusebenzeni.

Lo mkhawulo usebenza nalapho ulondoloza amaslayidi usebenzisa ikhodi ye-VBA noma ezinye izindlela zokwenza ngokuzenzakalelayo. Ngisho noma uzama ukuthumela izithombe ngobukhulu obukhulu, i-PowerPoint kuzonciphisa zibe yizinga eliphezulu langaphakathiIsibonelo, amaphikseli angu-3072 x 2304 esilayidi esingu-4:3.

I-Bitrate: esinye isici esibalulekile sekhwalithi yevidiyo

Ngale kwesisombululo (720p, 1080p, noma 4K), ikhwalithi yevidiyo ethunyelwe kusuka kuthuluzi lokuhlela (noma eguqulwe kusuka ku-PowerPoint ukuze ixutshwe ibe yi-montage enkulu) incike kakhulu ku- i-bitrate noma i-bit rateOkusho ukuthi, mangaki amaphuzu edatha ngomzuzwana asetshenziswa ukufaka ikhodi esithombeni.

Ngokwendlela engokoqobo, i-bitrate ephezulu isho ukuthi i-codec inayo Ulwazi olwengeziwe luyatholakala ngohlaka ngalunye ukumela imininingwane, ukugwema izinto zokucindezela nokugcina ubukhali obuhle, ikakhulukazi ezigcawini ezinokunyakaza okuningi noma ukuthungwa okuncane (amaqabunga, amanzi, ezemidlalo, njll.).

Kumakhamera e-DSLR amanje noma angenazibuko ungathola amanani e-bitrate ahlukahlukene kakhuluLokhu kusuka cishe ku-25 Mbps kuya ku-1000 Mbps kuma-codec ochwepheshe noma kuma-ProRes. Lokhu kusebenza futhi lapho uthumela kusuka ezinhlelweni ezifana ne-Premiere noma i-DaVinci Resolve, lapho ukhetha khona i-bitrate eqondiwe ngesandla.

Njengereferensi ewusizo, ngomsebenzi ojwayelekile kubhekwa ukuthi ku I-HD ephelele (1920 x 1080) i-bitrate yokuzungeza I-10-15 Mbps Ingavele inikeze ikhwalithi enhle yokusetshenziswa okuningi okuyisisekelo, inqobo nje uma okuqukethwe kungeyona inkimbinkimbi kakhulu; futhi uma udinga ukunciphisa usayizi ngaphandle kokulahlekelwa kakhulu, ungakwazi sebenzisa i-HandBrake ukucindezela ividiyo.

Esikhundleni salokho 4K Okungenani cishe I-60 Mbps Uma ufuna ukugcina ikhwalithi engaphezulu kweyanele, yize amakhamera amaningi ochwepheshe kanye nemisebenzi yokusebenza iya ku-100 Mbps noma ngaphezulu, ikakhulukazi uma usebenzisa ukucindezela kwe-All-I noma ama-codec aphakathi njenge-ProRes, lapho izinga ledatha lingakhuphuka khona liye kumanani afana no-400, 600 noma ngisho no-1900 Mbps.

Ingabe kufanelekile ukusebenzisa i-bitrate ephezulu kunesilinganiso esincane esinconyiwe?

Impendulo emfushane ukuthi Yebo, uma nje umsebenzi wakho ukuvumelaUkukhetha i-bitrate ephezulu kancane kunesilinganiso esinconywayo ngokuvamile kuletha izinzuzo ezicacile kuvidiyo, ngezindleko zokwandisa usayizi wefayela.

Nge-bitrate ephezulu uzothola Ukucaca okwengeziwe, ukubopha okuncane, amabhlogo okucindezela ambalwa Futhi, ngokuvamile, isithombe esihlala isikhathi eside ngaphambi kokukhiqizwa, ikakhulukazi uma uzokwenza ukulungisa imibala okunamandla, ukuhlela imibala ngendlela enamandla, noma imijikelezo eminingana yokucindezela nokucindezela.

Umehluko ubonakala kakhulu ezigcawini ezine- ukunyakaza okuningi noma imininingwane eminingi emincaneEzemidlalo, izithombe ezinezitshalo eziminyene, izimpophoma, intuthu, imvula, ithrafikhi esheshayo, njll. Ngaphansi kwalezi zimo, i-bitrate esheshayo iholela kuma-pixels okudansa, izindawo ezifiphele, noma amabhlogo "ayisikwele" asusa isithombe.

Ngokuphambene nalokho, ezithombeni ezicishe zingashintshi, ezinezizinda ezifanayo kanye nezinguquko ezimbalwa phakathi kwamafreyimu, i-bitrate ephezulu kakhulu ingaba ukuchitha isikhala, ngoba i-codec ayidingi idatha eningi kangaka ukuze imele into ehluka kancane kusukela kumzuzwana owodwa kuya kolandelayo.

Ngakho-ke, uma okubaluleke kakhulu kuwe kuyikhwalithi kanye isitoreji Akuyona inkinga; ungakhetha ama-bitrate amakhulu (ngaphezu kuka-15 Mbps ku-1080p kanye no-60 Mbps ku-4K) bese ulondoloza isikhala esengeziwe sokulungisa kanye nokugcina imininingwane ezigcawini eziyinkimbinkimbi.

I-bitrate ehlala njalo (CBR) vs i-bitrate eguquguqukayo (VBR) uma ithunyelwa kwamanye amazwe

Uma uthumela kusuka kubahleli bamavidiyo njengePremiere Pro noma iDaVinci Resolve, uzobona ukuthi, ngaphezu kokukhetha ukuthi ufuna ama-Mbps amangaki, ungakhetha futhi uhlobo lokufaka ikhodi yesilinganiso sebhithi: CBR noma VBR, futhi esimweni sokugcina, kudlula okukodwa noma okubili.

Ukukhetha kwe Isilinganiso sebhithi esihlala njalo (i-CBR) Kubangela ukuthi ividiyo ifakwe ikhodi ngenkathi kugcinwa izinga elifanayo le-bit kuyo yonke ividiyo, kungakhathaliseki ukuthi isithombe ngasinye silula noma siyinkimbinkimbi kangakanani.

Lokhu kunenzuzo yokuthi ukugeleza kwedatha kuyabikezelwa kakhulu, okuwusizo ekusakazweni okuthile noma ezingqalasizinda ezihleliwe, kodwa kusho ukuthi Izinsiza ziyachithwa ezigcawini ezilula futhi zingase zingaphumeleli ezigcawini eziyinkimbinkimbi kakhulu uma inani elibekiwe lingekho phezulu ngokwanele.

Ezimweni lapho iziqongo eziphakeme kakhulu zokunyakazaKuzinhlelo zokusebenza ezifana nama-drone e-FPV, ezemidlalo ezisheshayo, noma ukujaha izimoto, ukusebenzisa i-CBR ephansi kakhulu kungabangela ukweqa, ukuvimba okukhulu, kanye nokulahlekelwa okusobala kwemininingwane, ngoba i-codec ayinawo amandla okunikeza ama-bits amaningi ngokuguquguqukayo nangokufunwa.

Ngokwengxenye yayo, i Isilinganiso se-bit esiguquguqukayo (i-VBR) Ivumela i-codec ukuthi yabelane ngamabhithi amaningi noma ambalwa kuye ngokuthi kwenzekani ngesikhathi ngasinye sevidiyo, ikhuphule i-bitrate uma kunokunyakaza okuningi noma imininingwane emincane futhi iyinciphise lapho isithombe singashintshi kangako futhi kungadingeki idatha eningi.

Ngaphezu kwalokho, ku-VBR ungakhetha ukufaka ikhodi ku- Ukudlula okukodwa noma ukudlula okubiliKokunye, uhlelo luhlaziya futhi lufaka ikhodi ngokushesha, kanti kokunye kabili luqala ngokuhlaziya okuqukethwe kusukela ekuqaleni kuze kube sekugcineni, bese kuthi kokwesibili, lunqume ngokuhlakanipha ukuthi luzosebenzisa kuphi i-bitrate eningi nokuthi luzolondoloza kuphi.

Sebenzisa i-VBR ukuze Ukudlula okungama-2 Ngokuvamile kunikeza ibhalansi enhle kakhulu phakathi izinga lefayela nosayiziLokhu kuvumela ukulungiswa okunembe kakhudlwana kokusatshalaliswa kwama-bit, yize ngesikhathi sokuthumela kukhuphuka, into okufanele uyikhumbule kumaphrojekthi amade.

Yikuphi i-bitrate okufanele isetshenziswe kuye ngesisombululo kanye nohlobo lokusetshenziswa

Uma ulungiselela amavidiyo azodlalwa ku-inthanethi (i-YouTube, Facebook(ezinye izinkundla zokuxhumana) noma ezindaweni zokubikezela, kuyalulekwa ukuthi isinqumo kanye ne-bitrate kuyahambisana, ukuhlonipha ububanzi obunconywayo ukuze ukudlala kube bushelelezi ngaphandle kokulahlekelwa imininingwane eminingi kakhulu.

Amapulatifomu afana ne-YouTube ashicilela amashadi nge Amanani e-bit aphakanyisiwe emithwalo ye-SDR (standard dynamic range) kanye nokuqukethwe HDRFuthi i-algorithm yabo izogcina ifaka kabusha ividiyo yakho kwifomethi yangaphakathi abayisebenzisayo, kodwa uma usuvele uqala ngefayela eline-bitrate eqinile, umphumela ngemuva kokucindezelwa okwengeziwe uvame ukuba ngcono.

Isibonelo, kuma-1080p ku-25-30 fps anokuqukethwe "okuvamile", ukusakaza okuningi kusebenzisa ama-target bitrate aphakathi kwalawa 10 futhi 20 Mbpskuyilapho izincomo ze-4K zivame ukuqala cishe I-35-45 Mbps futhi uthuthukele kalula ku-60 Mbps noma ngaphezulu uma ufuna ikhwalithi engcono.

Ku-Premiere, lezi zinguquko zenziwa ku- iwindi lokuthumela ngaphandle, ngaphakathi kwesigaba se- Izilungiselelo ezisheshayo noma okufanayo, lapho ukhetha i-CBR noma i-VBR, inani lamaphasi, kanye ne-bitrate eqondiwe (futhi, esimweni se-VBR, kanye ne-bitrate ephezulu evunyelwe). Ku-DaVinci Resolve, izilungiselelo zitholakala ngaphakathi kwe- Ithebhu yokulethwa, esigabeni se- Izilungiselelo zokubonisaUngasebenzisa futhi amathuluzi aqondile ukuze Hlela futhi uguqule nge-FFmpeg Uma usebenza kusukela kumugqa we- imiyalo.

Khumbula ukuthi noma ulayisha ividiyo yakho ngekhwalithi ephezulu kakhulu, amapulatifomu afana ne-YouTube Bazoyicindezela futhi Futhi bazosebenzisa imikhawulo yabo ye-bitrate, ikakhulukazi uma ungafinyeleli iphrofayili yekhwalithi ephezulu (isibonelo, ama-VP9 noma ama-codec e-AV1). Noma kunjalo, ukuqala ku-master ene-bitrate ephezulu kuvame ukusiza ukuqinisekisa ukuthi ukufaka kabusha ikhodi kunezinto eziningi "ezibalulekile" zokusebenza ngazo.

Amathiphu awusizo okuphrojektha isethulo ku-1080p

Uma ulungiselela isethulo noma idokhumentari ozoyilungiselela iphrojekthi kuphrojektha ye-Full HD (1920 x 1080), njenge-BenQ HT2050A esikrinini esingamasentimitha angaba ngu-10 (noma ngaphezulu) futhi uzoyidlala usebenzisa i-laptop enamandla nge-HDMI, ungalungisa imininingwane ethile ukuze wandise ikhwalithi.

Esimweni esivamile lapho uhlanganisa khona izinto ezivela I-1080p kanye ne-4K zikhuphukele ku-1080pOkungcono kakhulu, ifayela lakho lokugcina kufanele libe ku-1080p, ligcine izinga le-bit elihle (isibonelo, phakathi kuka-20-30 Mbps uma usebenza ku-H.264) ukuze iphrojektha ibe nesignali ehlanzekile nezinzile.

Uma ividiyo yokugcina ikhiqizwe nge-PowerPoint, kungcono ukusebenzisa inketho ethi Dala ividiyo nge-Full HD (1080p) Bese kuthi-ke, uma uzoyihlanganisa ibe ukuhlela okuyinkimbinkimbi kakhulu, yifake ohlelweni lwakho oluthandayo ngokuphathelene naleso sinqumo ukuze ungaphindi uyicindezele ngokungadingekile.

Nge-laptop efana ne- I-Dell XPS 17 ene-RAM engu-16 GBAkufanele ube nezinkinga zokudlala okuqukethwe kwe-1080p nge-HDMI nge-bitrate ephezulu ngokulingene. Kodwa-ke, kufanelekile ukwenza izivivinyo zokuqala ngephrojektha yangempela egumbini lapho uzobe uhlela khona ukulungisa ukukhanya nokuqhathanisa futhi uqiniseke ukuthi akukho ukugxuma noma ezinye izinkinga. izinkinga zokuvumelanisa.

Kungumkhuba omuhle futhi ukuphatha nawe. ikhophi yokuphepha kusuka kufayela eliku-USB drive noma i-hard drive yangaphandle, futhi, uma kungenzeka, inguqulo ecindezelwe kancane uma kwenzeka ukuthi enye imishini yokudlala ingaphathi kahle ama-bitrate aphezulu kakhulu.

Ukuqonda indlela i-PowerPoint ephatha ngayo i-PowerPoint ukuthekelisa ividiyo (1080p, 4K) kanye nokuthekelisa isithombe seslayidiUkuqonda imikhawulo yesisombululo ngokwenguqulo ye-Office nokudlala ngohlobo lwe-bitrate kanye ne-encoding (CBR/VBR) kumathuluzi akho okuhlela kukuvumela ukuthi uthole okuningi kwezethulo zakho, kungakhathaliseki ukuthi uzibonisa ekamelweni elikhulu, uzabelane ngazo ku-inthanethi, noma uzihlanganise nemikhiqizo eyinkimbinkimbi kakhulu ye-audiovisual enekhwalithi ebonakalayo eqinile.

I-athikili ehlobene:

Ungasiguqula kanjani isethulo se-PowerPoint sibe yividiyo ngaphandle kokulahlekelwa yikhwalithi
