Okudingeka Ukwazi Ngama-High Definition Camcorders Ngaphambi Kokuthenga
Ama-camcorders encazelo ephakeme (HD) ayinhlangano yemvelo yenani elikhulayo lama-HDTV emakamelweni ethu okuhlala. Amanani kuma-camcorders e-HD aqhubeka ewa, kuyilapho abaningi abakhiqizi be-camcorder banda inani lezinhlobo ze-HD ezithwalayo.
Ngezansi umhlahlandlela omfushane kuma-camcorders we-HD, umahluko phakathi kwamakhamera wekhwalithi ejwayelekile nephezulu ephezulu, izinqumo zevidiyo ezisekelwe ngamakhamera, nokuningi.
I-SD vs HD Camcorders
Njengoba kufana nethelevishini, umehluko phakathi kwencazelo ejwayelekile kanye nekhamera yezincazelo eziphezulu ukulungiswa kwevidiyo.
Ividiyo oyibonayo ku-TV yakho noma kwikhompyutha yakho yenziwe ngamakhulu emigqa ehlukile. I-definition definition ye-standard inezingqikithi ezingu-480 ezizungezile zokuxazulula kodwa ividiyo ephakeme kakhulu ingaba ngu-1,080. Imigqa yokuxazulula okuningi onayo, ividiyo yakho ebukhali iyobukeka.
Kunezinqumo ezintathu ezinkulu zevidiyo ze-HD ezitholakalayo: 1080p, 1080i, no-720p. Ama-camcorders amaningi e-HD emkhokheni wemakethe nganoma yisiphi isinqumo se-720p noma se-1080i.
I-1080i vs 1080p vs 720p Video
Umehluko omkhulu phakathi kwalezi zindlela ezintathu ukurekhoda ividiyo. I "p" ekupheleni kuka-1080p no-720p imelela "ukuskena okuqhubekayo." I "i" elandela i-1080i imele ihambe phakathi.
I-Interlaced Video: Ividiyo evamile yokuchaza ejwayelekile ividiyo ephakathi, njengama-1080i. Kuvidiyo elandelanayo, i-camcorder yakho izorekhoda zonke izigaba zokuxazulula. Iqala ngokubonisa imigqa eyodwa, emithathu, neyesihlanu bese kamuva ilandela imigqa emibili, emine, neyisithupha.
I-Scan Scan ye-Progressive: Amarekhodi we-scan aqhubekayo elayini ngalinye levidiyo ngokulandelana ngaphandle kokudlula noma yimaphi imigqa. Ngakho-ke, kuzoqala kuqala ngomugqa owodwa bese usebenza ngendlela yonke eya ku-line 1080. Ividiyo yokuskena eqhubekayo ibonakala ibhetele kunomlingani wayo ohlangene uma kuziwa kwividiyo esheshayo (njengezemidlalo).
Iyini i-HD egcwele ne-AVCHD?
I-HD egcwele yisikhathi sokumaketha esibhekisela kumakhamera aqoshiwe ku-1920x1080 isinqumo. Ngokuvamile, uzothola ividiyo ebukhali kusuka kumakhamera aqoshiwe kulesi sinqumo kunokuba ungayisebenzisa nge-model model ye-720p.
I-AVCHD (i-Advanced Advanced Codec High Definition) ibhekisela kwifomethi ephezulu yevidiyo esetshenziswe ngu-Sony, i-Panasonic ne-Canon, phakathi kwabanye. Yindlela yokucindezela futhi ulondoloze ividiyo ecacile ephezulu kwimidiya yesitoreji sedijithali njengezinkinobho zediski eyinkimbinkimbi namakhadi omemori e- flash. Ukuze uthole ulwazi oluningi ngefomethi ye-AVCHD, sicela ubheke lokhu kulo mhlahlandlela kufomethi ye-AVCHD.
Yiziphi izinhlobo zama-Camcorders we-HD atholakalayo?
Amakhamera we-HD afika kuzo zonke izinhlobo, ubukhulu, namaphuzu wamanani kuzo zonke izikhiqizi ezinkulu ze-camcorder. Ungathola izindleko eziphansi, amamodeli "ephaketheni" angaphansi kuka-$ 200 futhi agcwele, afakwe ngamakhamera angaphezulu kwe $ 1,500, nakho konke okuphakathi.
Empeleni, eziningi ze-Smartphones zanamuhla ziqoshwa ngo-1080p. Lokhu kuqeda isidingo sokuba ngisho ne-camcorder ezinikezele, ikakhulu uma ungadingeki ukurekhoda ividiyo nganoma yini enye ngaphandle kwalokhu noma lowo mcimbi, noma kumnandi.
Njengamanje kunamakhamera ephezulu-definition yamaklayenti atholakalayo ukuthi athole ividiyo irekhodi kumathonta we-MiniDV, ama-DVD ama-DVD, ama-drive asebenzayo, imemori ye-flash kanye ne-Blu-ray discs.
Ihlehliselwa kuma-Camcorders we-HD
Ngenkathi ividiyo yekhwalithi ephezulu impela ibe ne-plus, ibuye iveze izinselelo ezimbalwa. Okukhulu kakhulu ukuyigcina.
Amafayela wevidiyo we-HD angaphezulu kakhulu kunamafayela echaza incazelo ejwayelekile. Lokhu kusho ukuthi imidiya yakho ye-camcorder ( ikhadi le-SDHC, i- HDD, iTape, i-DVD, nezinye izakhiwo zememori ) zizogcwalisa ngokushesha nge-camcorder ye-HD.
Ngenxa yokuthi ubhekene namasayizi amafayela amakhulu amakhulu wevidiyo, ividiyo ye-HD izobeka futhi izidingo ezinkulu kukhompyutha yakho. Ezinye izinhlelo ezindala ezinamandla okucubungula angeke zikwazi ukubonisa ividiyo ye-HD. Abanye bazoyidlala, kodwa kancane kancane futhi banokuningi okuphazamisayo.
