mafani ambiri akuonera apamwamba kanema ndi kusamvana zambiri anakumana ndi mtundu AVCHD. Kodi mtundu umenewu ndiponso mmene kumasiyana ndi zonse zinalengedwa pamaso tsopano ndi tidzakambirana. Komanso mwapadera ilipiridwa kwa sayansi ndi mapulogalamu, amene amalola kuti ntchito watsopano AVCHD muyezo.

AVCHD: wotani mtundu?

Ngakhale pa nthawi zifika video, phokoso amachita mbali. Lokha decrypt kuchepetsa umenewu akunena makamaka patsogolo Video Codec Mkulu Tanthauzo (a mwaukadauloZida ndi Video Codec Mkulu Tanthauzo).

Muyezo ndi luso watsopano ndi amagwiritsa psinjika kanema zochokera psinjika MPEG4 AVC / H.264.

Other kujambula ndi vidiyo akamagwiritsa Mwachitsanzo, MPEG2 latsopano muyezo momveka bwino kutaya, chifukwa AVCHD akukamba wabwino pa mlingo wa 720P, 1080p, ndi 1080p, ndi kuchepetsa kufunika kwa kusunga deta.

History ndi mitundu

Ngati inu mukuyang'ana pa mbiri chitukuko, mtundu AVCHD kujambula pachiyambi analengedwa monga ngati njira kwa HDV muyezo komanso nkhanza za m'banja, zomwe mpaka posachedwapa zinkachitika mu ogula ndi akatswiri camcorders.

Kwa nthawi yoyamba muyezo atsopano anayamba kupanga mu 2006 bungwe Matsushita Zamagetsi Industrial Co. Ltd., zomwe mwachangu anathandizana ndi mmodzi wa atsogoleri m'munda wa chithunzi, video ndi Audio - dziko otchuka Panasonic. Ndiye ntchito mtundu watsopano anachepetsedwa yekha makamera lapansi.

Izo zinali kokha mu 2008, mogwirizana ndi Sony Corporation waneneratu olimba boma kujambula luso, zimene zinachititsa kuti maonekedwe a camcorders woyamba akatswiri.

mtundu woyambirira yokha nthawi kakusintha zina (pakhala Mabaibulo angapo ndi magawo osiyana ndi mwamakonda). Pakali pano, akusiyanitsa zotsatirazi:

• AVCHD Lite - Lite mtundu ndi chikalata cha mizere 720 okha ndi pafupipafupi kujambula 24, 50 kapena 60 FPS;
• AVCCAM - mtundu akatswiri makamera kanema zochokera 3-masanjidwewo CCD-kachipangizo kulola mlingo pang'ono kulemba 24 Mbit / s, chikugwirizana kudutsa XLR maikolofoni athandizira ndi sitolo kanema pa SSDs;
• NXCAM - «woyera» mtundu kuchokera Sony, amatha kujambula kanema pa khalidwe 720P, 1080p, ndi 1080i, koma osati ntchito ndi mlingo chimango 24, 25 ndi 30 FPS;
• AVCHD 3D / Progressive - mtundu 2011 pomwe kuti Baibulo 2.0, amathandiza stereoscopic kanema kujambula ndi 1080p / magawo 50-60fps).

ntchito codecs kanema

Koma kanema, ntchito codecs ndi decoders kwakukulukulu zochokera MPEG-4 luso psinjika Komabe, ndi ochepa asadziphe.

Ikani pa kanema codecs sanali kugwira ntchito kwa XP. Kuti tichite zimenezi, muyenera kokha kupeza Baibulo atsopano a otchuka phukusi K-Lite. Koma mu ndondomeko ya unsembe mmalo mwa muyezo ya akufuna "dongosolo" chophimba, sankhani mwaukadauloZida ndi bango zinthu zonse kuperekedwa mu mndandanda.

Komanso, installable kanema codecs kwa XP kapena pamwamba Mulingo wa dongosolo akhoza kugawidwa m'magulu awiri - AVCHD-Sd (muyezo tanthauzo) ndi AVCHD-HD (High Tanthauzo). Kuchokera pa ichi, ife tikhoza kusintha makhalidwe poyerekeza miyezo onse.

decoders zomvetsera

Ndi malonda zomvetsera si mophweka. Maziko a kutembenuka chizindikiro kuika umisiri ziwiri zikuluzikulu - liniya PCM ndi Dolby Intaneti. Komabe, ngati phokoso, anthu ambiri bwino sindikumvetsa kusiyana khalidwe ndi kugawa audio.

Choncho, pazifukwa zina, anthu ena amene adzaitana khalidwe kujambula phokoso mtundu 5.1, 7.1 kapena 8.1. Kumbukirani: si quality, koma n'zotheka yogawa chizindikiro mu nkhani panolamiki.

Mungamuyandikile ndi fanizo zipangizo otchedwa crossovers. Angagaŵire pafupipafupi ndi kuwatsogolera kwa okamba yoyenera. Ngati aliyense amakumbukira, mu nthawi Soviet opangidwa ndime Radiotehnika S Series ndi lotseguka kunja gululi, amene pansi pa otsika-pafupipafupi phirilo pano pakati - ndi midrange ndi pamwamba - tweeter.

Olumikizidwa kwa mkuzamawu kusinthanitsidwa akhoza kufika yeniyeni pafupipafupi osiyanasiyana lolingana ndi makhalidwe a wolankhulayo awombe.

Koma mu mfundo za kufalitsidwa kwa akuzinga-phokoso ntchito bokosi panolamiki. A khalidwe zomvetsera anatsimikiza ndi mlingo pang'ono ndi zochepa chabe pamalangizo pafupipafupi. Mu nkhani iyi, zomvetsera akhoza idzaseweredwe kumbuyo ndi makhalidwe pa mlingo wa 320 kbit / s ndipo 96 kHz (akatswiri phokoso, magawo ofanana ndi mtundu lossless).

dera ntchito

Tsopano, ina ya AVCHD muyezo. Kodi mtundu wa mtundu ndi pang'ono zomveka. Tiyeni tiyang'ane pa malo otchuka kwambiri tanthauzo lake.

Osanenapo n'zotheka ntchito mfundo imeneyi ponena mafilimu kuwombera kapena mwa mawu a processing kanema kapena zomvetsera chizindikiro, mwina kudziŵika kuti malangizo waukulu wa chitukuko, kusinthidwa ndi ntchito ya kanema digito wakhala, makamaka HDTV amalandira, digito njira malipiro.

Mwa njira, mu Brazil chomwecho, muyezo umenewu ntchito dziko lonse la ntchito digito TV. Ku South Korea, ndi ophatikizidwa mu dongosolo Intaneti Multimedia Kuwulutsa, ndi Japanese utumiki Fuji TV ndi NHK mfundo imeneyi kugwirizana ndi gawo la mafoni a msika.

zonyamulira

Tinganene, kusunga malangizo mu njira yotero ya psinjika za kanema ndi Audio kabisidwe ntchito abulusa olimba boma. Ngati pachiyambi cha kukula kwa muyezo umenewu ntchito kokha Blu re zimbale kapena TV wapadera AVCHD (8 cm), lero mtundu file, inu mosavuta kupulumutsa pa galimoto zolimba kapena zochotseka khadi kukumbukira, Memory Ndodo ovomereza ndi Sd.

funso ili: kodi kubereka kapena kusintha zinthu? Pali njira zingapo.

AVCHD: mumatsegula?

Ngati ndi dongosolo mapulogalamu mwa mawu a play, nkhani kuti kupezeka kwa codecs ndi decoders ntchito iliyonse mu mawonekedwe a player kapena pulogalamu kuzindikira mtundu kanema mosavuta.

Mu Baibulo ofunika kwambiri, mungathe kugwiritsa ntchito yomweyo Windows Media Player, kapena chidwi mankhwala otchedwa VLC Media Player. Chotero pulogalamu ambiri video, poyamba, ali ndi mphamvu kwambiri kuposa muyezo Windows zikutanthauza.

Monga mankhwala, pali mavuto ena. Choyamba, vuto lalikulu ndi kutengera zinthu ndi kamera kapena AVCHD chimbale. dongosolo wapamwamba TV UDF 2.5 «ekspishkoy" sagwirizana. The njira yosavuta vutolo ndi kukhazikitsa zina mapulogalamu phukusi Nero InCD.

Komanso owona eni anagwidwa pa kamera akhoza adzaikidwa mu mtsinje Directory, amene zobisika Directory muzu wa chipangizo kapena boma mumafooda.

Kutsegula mothandizidwa ndi zipangizo akatswiri monga Sony Vegas ovomereza kapena chinachake si takambirana.

Tengani kanema mu mtundu uwu ngakhale pulogalamu monga ofunsira processing zomvetsera monga Sony Sound Forge kapena Adobe mayeso CS.

Sinthani AVCHD kwa mtundu wina

AVCHD kusamutsa kuti akamagwiritsa ena angathe kuwaŵerenga, kawirikawiri ntchito converters wapadera mapulogalamu, amene angapezeke lero, monga mmene kutero.

Mfundo ambiri yafupika chokha chakuti, kusankha zinthu kukhala akatembenuka, ndipo mwachindunji mtundu kopita deta. Mu zoikamo inu akhoza ku- kusankha kanema zoyenera ndi zipangizo zomvetsera processing.

m'malo zotsatira

Apa, kwenikweni, ndi chirichonse chochita ndi muyezo AVCHD kanema. Kodi mtundu uwu ndi chiyani ubwino wake, ndi bwino kupenda mwachindunji pamene kuonera zinthu mofanana matelevizioni lathyathyathya-gululi. Poyerekeza akamagwiritsa ena panopa alipo, ichi ndi wapamwamba kwambiri, kuwonjezera, si zinthu zogwirira makamera opondereza TV, kompyuta kapena zipangizo ngakhale yam'manja. Mwa njira, njira kanema psinjika wanyamula chuma moti aliyense TV yosungirako malo kwambiri, monga lingaliro anali kuti palibe. Ambiri - ubwino.
