Kwadalwa ngo 11.04
Cabanga ukuthi uphakathi kokuxhumana ividiyo neklayenti noma uphila umcimbi, bese ikhamera yakho ye-USB iyama ngokungazelelwe—ama-frame ayashoda, ukuhamba kwakho kuba neziphithiphithi, futhi ababukeli bakho bahluleka ukuhambisana. Ukushoda kwe-frame kuUSB camera modulesis one of the most frustrating issues for remote workers, content creators, and hobbyists alike. The good news? It’s rarely a hardware death sentence. Most cases stem from fixable problems with connections, drivers, or system settings. In this guide, we’ll break down the root causes and walk you through step-by-step solutions to restore smooth, consistent video.
1. Yini empeleni edala ukuwa kweframe kumakhamera e-USB?
Ngaphambi kokungena ezixazululweni, ake sichaze ukuthi kungani amakhamera e-USB ehla amafreyimu. Ngokungafani nezithombe zangaphakathi, ama-modules e-USB axhomeke ezixhumanisweni zangaphandle nasezinsizakweni zesistimu ezabelwe—noma yikuphi ukuphazamiseka kulezi zixhumanisi kungaphula ukuhamba kwevidiyo. Izimbangela ezivamile zifaka:
• Izixhumi ze-USB ezinamandla aphansi: Amakhebuli aphukile, izikhala ezinamandla aphansi, noma ama-hub angahambelani.
• Abashayeli abaphukile noma abaphukile: Isofthiwe exhumanisa ikhamera yakho nesistimu yokusebenza.
• Ukuncintisana kwe-USB bandwidth: Imishini eminingi idlalela ububanzi obulinganiselwe be-USB controller.
• Izinsiza zesistimu ezithwele kakhulu: Ukusetshenziswa kwe-CPU, i-RAM, noma idiski kukhuphuka ngenxa kwezinhlelo ezisemva.
• Izilungiselelo ze-camera/software ezingalungile: Isixazululo noma izinga le-frame limisiwe phezulu kunalokho i-camera engakwazi ukukhandlela.
Ukuqonda lezi zikhuthazo kuzokusiza ukuthi uqonde kahle izixazululo—akusekho okungazami-nokungazami.
2. Isinyathelo 1: Qala ngokuqinisekisa Izinsiza eziyisisekelo (Izixazululo zeMizuzu Emihlanu!)
Iningi lezinkinga zokulahleka kweframe linenkqubo ezilula zehardware. Qala lapha ngaphambi kokuhamba ezixazululweni eziyinkimbinkimbi:
Bheka i-USB Cable
Izikhebhe ze-USB ziyizimbangela ezivame ukungabhekwa. Izikhebhe ezishibhile, ezindala, noma ezisezingeni eliphansi zihluleka ukudlulisa idatha ngokungaguquguquki.
• Shintsha izintambo ezindala: Bheka ukuhuzuka, ama-connectors akhinyayo, noma ukushintsha kwemibala—lezi zibonakaliso zokulimala.
• Sebenzisa izintambo ze-USB 3.0 (noma phezulu): Uma ikhamera yakho isekela i-USB 3.0 (eboniswa ngephothi eliluhlaza), intambo ye-USB 2.0 izobangela ukuvinjelwa kokudluliswa kwedatha. I-USB 3.0 inikeza i-5Gbps bandwidth, uma kuqhathaniswa ne-480Mbps ye-USB 2.0—okubalulekile ku-1080p/4K ividiyo.
• Gcina izintambo zifushane: Izintambo ezinde kunezingu-3 (10 feet) ziba nezinkinga zokwehla kwesignali. Sebenzisa intambo ye-USB yokwandisa esebenzayo uma udinga ubude obengeziwe—ukwandiswa okungasebenzi kahle kubi kakhulu.
Testa Iziphumo Ezingafani ze-USB
Ayikho yonke imikhono ye-USB efana.
• Gwema izimbobo ze-USB 2.0 zamakhompyutha aphezulu: Uma ikhamera yakho ikhipha i-1080p/60fps noma i-4K, i-USB 2.0 ayikwazi ukuhamba. Xhuma kwi-port eluhlaza (USB 3.0), ebomvu (USB 3.1), noma eyellow (ihlala ivuliwe).
• Phuma ezikhungweni ze-USB (okwesikhashana): Izikhungo eziphumayo zihlukanisa ibhendi phakathi kwezinsiza futhi ngokuvamile azinawo amandla anele. Xhuma ikhamera ngqo kukhompyutha yakho kuqala—uma amafreyimu ehluleka ukuwa, isikhungo siyinkinga.
• Zama i-hub ye-USB enegesi: Uma udinga amadivayisi amaningi, sebenzisa i-hub enesixhumi sokuphakelayo sangaphandle (i-hub esebenzayo). Iphakela amandla aqinile futhi yehlisa umthwalo we-bandwidth ku-USB controller ye-PC yakho.
Bheka Ikhamera Ngokwayo
Ngokuvamile, imishini yekhamera ayisebenzi kahle—kodwa ukuhlola okusheshayo kungakhipha lokhu:
• Hlanza i-USB connector kukhamera ngensipho eyomile (ukwakheka kwedust kuholela ekuxhumaneni okungapheli).
• Hlola ikhamera kwenye ikhompyutha: Uma iphonsa amafreyimu lapho futhi, ikhamera ingase ibe nephutha. Uma isebenza, inkinga ikwisistimu yakho yokuqala.
3. Isinyathelo 2: Vuselela noma Faka Kabusha Abashayeli BeKhamera
Abashayeli benza njengabahlaziyi phakathi kwekhamera yakho ne-OS. Abashayeli abaphumelelayo noma abaphukile bangabangela ukungaqondi kahle—futhi ukwehla kwamafreyimu. Nansi indlela yokubaphatha ku-Windows nase-macOS:
Ngokwe-Windows 10/11
1. Press Win + X and select Umphakathi Wamadivayisi.
2. Khulisa ingxenye yeZithombe noma Amadivayisi Okuthwebula.

2. Chofoza kwesokudla ku-USB Root Hub (USB 3.0) futhi ukhethe Izakhiwo.
3. Iya kuthebhu yePower—lapha uzobona zonke izinsiza ezixhunywe kulowo hub.
4. Uma ubona amadivayisi amaningi anebhendi ephezulu (isb. SSD + ikhamera ye-4K), aphikisana ngebhendi.
Izixazululo Zezinkinga Zokuxhumana
• Susa amadivayisi e-USB angabalulekile: Khulula ama-hard drive angaphandle, amaphrinta, noma ama-USB hubs uma usebenzisa ikhamera. Ngisho ne-USB mouse/keyboard isebenzisa ibhendi encane, kodwa yonke ingxenye iyasiza.
• Ph spread devices phakathi kwabaphathi be-USB: I-PC eziningi zine-2–4 abaphathi be-USB. Xhuma ikhamera kwi-port exhunywe kumphathi ohlukile (hlola imanuwali ye-PC yakho ukuze uhlole amapoti kumaphathi).
• Nciphisa isixazululo sekhamera / izinga lokukhuphuka okwamanje: Uma ungakwazi ukuhoxisa amadivayisi, yehlisa ukukhipha kwekhamera (isb., kusuka ku-1080p/60fps kuya ku-720p/30fps). Lokhu kunciphisa ukusetshenziswa kwe-bandwidth ngama-75%.
5. Isinyathelo 4: Thuthukisa Isofthiwe Nezinhlelo Zokusebenza
Izinhlelo ezisebenza ngemuva kanye nesofthiwe engalungile ivamise ukuthatha izinsiza ezidingekayo ukuze kuqhutshwe ividiyo kahle. Nansi indlela yokwenza kube lula uhlelo lwakho:
Vala Izinhlelo Ezidla Izinsiza
• Windows: Vula i-Task Manager (Ctrl + Shift + Esc), uye kuthebhu ye-Details, bese uhlele nge-CPU noma i-Memory. Vala izinhlelo ezisebenzisa >10% ye-CPU (isb., abahleli bevidiyo, imidlalo, amathuluzi wokuhlanganisa amafayela).
• macOS: Vula i-Activity Monitor (Finder > Utilities), hlunga nge-CPU noma i-Memory, bese uphonsa izinhlelo zokusebenza ezisebenzisa kakhulu.
Critical note: Ukuhlolwa kwe-antivirus kanye nezibuyekezo ze-Windows/macOS kungakhuphula ukusetshenziswa kwe-CPU. Misa lokhu okwesikhashana ngesikhathi sokuqhafaza/ukugeleza okubalulekile.
Lungisa Izilungiselelo Zekhamera Ne-App
Iningi lezinhlelo zokusebenza zevidiyo (Zoom, OBS, Teams) likuvumela ukuthi ushintshe izilungiselelo zekhamera—sebenzisa lezi ukuze unciphise umthwalo:
• Ukunciphisa isixazululo / isivinini sokuhamba: Ku-Zoom, iya ku-Zilungiselelo > Ividiyo bese usetha “Isixazululo seKhamera” sibe ngu-720p. Ku-OBS, ngaphansi kwe-Device Yokuthwebula Ividiyo, setha “Isixazululo” sibe ngu-1280x720 kanye “ne-FPS” sibe ngu-30.
• Vala izici ezingadingekile: Vala “Ukubuyiselwa Kokukhanya Okuphansi” (kudonsa i-CPU) noma “Ukukhulisa Kwedijithali” (kwengeza umthwalo wokucubungula) ohlelweni lwekhamera yakho.
• Vula ukuhamba phambili kwehardware: Ku-apps ezifana ne-Chrome (Izilungiselelo > Uhlelo) noma i-OBS (Izilungiselelo > Ukuphuma), vula “Ukuhlela ividiyo okuhamba phambili kwehardware.” Lokhu kudlulisa umsebenzi ku-CPU yakho kuya ku-GPU yakho, kunciphisa ukulibaziseka.
Lungisa Izilungiselelo Zamandla (Windows)
Imodi yokonga amandla ye-Windows iyanciphisa amandla e-USB kanye nokusebenza kwe-CPU—kubuhlungu kumakhamera.
1. Iya ku-Control Panel > Izinketho Zamandla.
2. Khetha Ukusebenza Okuphezulu (noma “Ukusebenza Okungcono” ku-Windows 11).
3. Chofoza Shintsha izilungiselelo zephakheji > Shintsha izilungiselelo zamandla ezithuthukisiwe.
4. Vula izilungiselelo ze-USB > Izilungiselelo zokumisa okukhethwayo kwe-USB futhi uzibeke ku-Disabled.
6. Isinyathelo 5: Xazulula Izinselelo Zomshini
Uma uzame konke okukhuluma ngenhla futhi usenokwehla kweframe, uhlelo lwakho noma ikhamera yakho ingase ibe nemikhawulo ye-hardware:
Amakhompyutha Amadala noma Angasebenzi Kahle
• Izithiyo ze-CPU: Ama-CPU amabili (ajwayelekile kumalaptop endala) abhekana nezithombe ze-1080p/60fps. Thuthukisa ube ne-CPU emine uma kungenzeka, noma gcina ku-720p/30fps.
• I-RAM enganele: I-RAM engaphansi kwe-8GB ibangela ukuthi izinhlelo zishintshe idatha kudiski, okuholela ekubambezelekeni. Thuthukisa ube ne-16GB ukuze uthole ividiyo esheshayo.
Izing限制 zeKhamera
Izithombe ze-USB ezibiza kancane (ngaphansi kwe-$50) ngokuvamile zine-sensors yezithombe noma ama-processors anokwehla. Uma eyakho ingakwazi ukuphatha i-1080p ngaphandle kokwehla kwamafreyimu, cabanga ngokuthuthukisa uye kumodeli ephakathi (isb., Logitech C922, Razer Kiyo) enokuhlanganiswa kwe-hardware okungcono.
Pro tip: Bheka amakhamera anokuthi “H.264 hardware encoding”—lokhu kushintsha ukuhlanganiswa kwevidiyo kusuka kwi-PC yakho kuya kukhamera, kunciphisa umthwalo we-CPU.
7. Izinyathelo Zokuvikela: Gwema Ukuwa Kweframe Okwejwayelekile
Uma usulungile inkinga, qinisekisa ukuthi ayibuyele emuva ngalezi zindlela:
• Vuselela abadlali njalo ngenyanga: Beka izikhumbuzo zokuhlola iwebhusayithi yomkhiqizi ukuze uthole izibuyekezo ze-drivers zekhamera.
• Sebenzisa amaphoyinti e-USB akhethekile: Gcina iphoyinti le-USB 3.0 elikhethekile lenkanyezi yakho—ungafaki ezinye izinsiza kulo.
• Hlanza ikhamera yakho njalo: Uthuli ku-sensor noma ku-USB connector kubangela izinkinga eziphindaphindiwe. Sula i-lens nge-microfiber cloth kanye ne-USB port nge-compressed air.
• Testa ngaphambi kwezikhathi ezibalulekile: Yenza ucingo lokuhlola lwezimizuzu ezi-5 emizuzwini engama-30 ngaphambi kwemihlangano/ukuhambisa ukuze ubambe ukuwa kweframu kusenesikhathi.
8. Izeluleko Zokugcina Zokuxazulula Izinselelo
Uma usaqhubeka:
• Zama enye i-app yekhamera: Sebenzisa i-Windows Camera (Windows) noma i-Photo Booth (macOS) ukuze uhlole ikhamera. Uma isebenza lapha kodwa ingasebenzi ku-Zoom/OBS, inkinga ikwi-app (faka kabusha).
• Vuselela i-OS yakho: Izingxenye ezindala ze-Windows/macOS zineziphazamiso ze-USB controller. Faka izibuyekezo zakamuva.
• Xhumana nosizo lomkhiqizi: Uma ikhamera isesikhathini sokwaziswa, chaza izinyathelo zakho—bangase bayishintshe uma ibhujiswa.
Isiphetho
Ukwehla kwamafreyimu kumamojula we-USB camera kuyinkinga, kodwa cishe njalo kuxazululwa. Qala ngokuqinisekisa izinto ezisheshayo (amakhabe, izikhala) ngaphambi kokuhamba kumadrayivu nokuphathwa kwe-bandwidth—lezi zinyathelo zilungisa u-80% wezinkinga. Ngemva kwezinkinga eziqhubekayo, lungisa izilungiselelo zohlelo lwakho noma uthuthukise imishini engaphansi kwamandla. Ngokulandela le mhlahlandlela, uzobuyela ezikhathini ezithokozisayo zokuxhumana ngevidiyo, ukuhamba, nokurekhoda ngaphandle kwesikhathi.
