AVCHD - onjani format? Advanced Isiqophi Ikhodekhi High Definition - Advanced Isiqophi Ikhodekhi High Definition

abalandeli abaningi ebukela high video quality kanye nesinqumo kaningi sibhekene ifomethi AVCHD. Kuyini lokhu format futhi ukuthi lihluke kanjani konke okudalwe phambi manje futhi kuzoxoxwa. Ngaphezu kwalokho, ukunakekelwa okukhethekile izokhokhwa ubuchwepheshe kanye nezinhlelo, okuvumela ukusebenza entsha AVCHD ejwayelekile.

AVCHD: onjani format?

Nakuba ngaleso sikhathi kuziwa ividiyo, umsindo kunendima okuyifezayo. Wona ukubethelwa kwaleli ukunciphisa likhuluma ngokuqondile eziphambili Isiqophi Ikhodekhi High Definition (Advanced-Video Ikhodekhi High Definition).

Le ndinganiso ubuchwepheshe empeleni esasisesisha futhi isebenzisa isiqophi kokucindezelwa esekelwe kokucindezelwa MPEG4 AVC / H.264.

Okunye ukurekhoda ividiyo nezakhiwo, isibonelo, MPEG2 standard entsha kokulahlekelwa ngokucacile, ngoba AVCHD ediliva nqampuna umhlabeleli ezingeni 720p, 1080p, futhi 1080p, kuye kwanciphisa ukufunwa isitoreji idatha.

Umlando ezahlukeneyo

Uma ubheka umlando ukuthuthukiswa, AVCHD ukuqoshwa format ekuqaleni umuntu wadalwa njengendlela uhlobo elinye ithuba HDV ejwayelekile futhi DV, kuze kube muva nje elanqoba ngayo umthengi professional camcorders.

Ngokokuqala ngqá indinganiso entsha yasungulwa ngo 2006 corporation Matsushita Electric Industrial Co. Ltd., ngaleso sikhathi ngenkuthalo wabambisana omunye wabaholi emkhakheni isithombe, video kanye alalelwayo - the Panasonic abaziwa umhlaba wonke. Bese sebenzisa ngefomethi entsha lancipha kuphela ukuba amakhamera.

Kwakungenxa nje ngo-2008, ngokubambisana neNhlangano-Sony Corporation umemezele okurekhodiwe ubuchwepheshe okuqinile-state, okwaholela ukubonakala camcorders lochwepheshe kuqala.

ifomethi kokuqala ngokwayo ngokuhamba kwesikhathi usebhekene izinguquko ezithile (sekube izinguqulo eziningana ngayo nemingcele ezahlukene kanye ngokwezifiso). Kuze kube manje, wenza umahluko phakathi kwalokhu okulandelayo:

• AVCHD Lite - format lite isinqumo imigqa 720 kuphela futhi imvamisa ukwakheka kwendaba 24, 50 noma 60 FPS;
• AVCCAM - format professional isiqophi amakhamera esekelwe 3--matrix be-CCD-inzwa ngokuvumela ngesilinganiso kancane ukurekhoda 24 Mbit / s, exhunywe yonkana XLR umbhobho okokufaka kanye nokugcina amavidyo ku SSDs;
• NXCAM - «ahlanzekile» format Sony, uyakwazi ukurekhoda ividiyo ngekhwalithi 720p, 1080p, futhi 1080i, kodwa ayisebenzi nge izinga lozimele 24, 25 no-30 FPS;
• AVCHD 3D / Progressive - format 2011 yisibuyekezo inguqulo 2.0, isekela isiqophi stereoscopic ukuqopha nge 1080p / imingcele 50-60fps).

ukusetshenziswa video codecs

Nokho, njengoba zevidiyo, wasebenzisa amakhodekhi futhi decoders ingxenye enkulu zisekelwe-MPEG-4 kokucindezelwa ubuchwepheshe, ube ambalwa nezinye izinketho.

Fakela afanayo wevidiyo awazange ukusebenzela XP. Ukuze wenze lokhu, kudingeka nje wena ukuthola inguqulo yakamuva ye iphakethe ethandwa K-Lite. Kodwa inqubo yokufaka esikhundleni isethi esezingeni okuhlongozwayo "Isethaphu" screen, ukhethe Advanced futhi uphawu kuzo zonke izingxenye okwethulwa ohlwini.

Ngaphezu kwalokho, iyafakeka isiqophi amakhodekhi ngoba XP noma ngaphezu isikhundla kohlelo zingahlukaniswa izigaba ezimbili - AVCHD-SD (ukucaca okujwayelekile) kanye AVCHD-HD (Ukucaca). Ngokusekelwe lokhu, singanciphisa izici ngokuqhathanisa kokubili amazinga.

decoders alalelwayo

Nge ibhizinisi umsindo kunjalo elula cha. Ngesisekelo ukuguqulwa isignali ukubeka ubuchwepheshe ezimbili eziyinhloko - Linear PCM futhi Dolby Digital. Nokho, njengoba i-umsindo, abantu abaningi ngokucacile abaqondi umehluko phakathi izinga nokusatshalaliswa umsindo.

Ngakho, ngenxa yezizathu ezithile, abanye abasebenzisi shayela izinga ekurekhodeni format 5.1, 7.1 noma 8.1. Khumbula: akusiyo izinga, kodwa kuphela ukuthi kungenzeka isignali ukusatshalaliswa endaweni mayelana indawo engezansi.

Ungasondela isifaniso namadivayisi ngokuthi crossovers. Bangakwazi ukwabelana imvamisa futhi awaqondise kuya izikhulumi ezifanele. Uma umuntu uyakhumbula, ezikhathini Soviet ekhiqizwa ikholomu Radiotehnika S Series nge iphaneli evulekile ngaphandle, lapho phansi ephansi imvamisa Isigaxa ekhona phakathi - Midrange futhi phezulu - tweeter.

Ixhunyiwe kwi-crossover amplifier eyithumela ethile imvamisa uhla elihambisana umsindo izici isikhulumi.

Kodwa ngokuya ukusatshalaliswa ozungezayo-umsindo esetshenziswa isici engezansi. A izinga umsindo kunqunywa bit futhi izibonelo zalokho imvamisa. Kulokhu, umsindo ingadlalwa enesivumelwano izici ezingeni 320 kbit / s no 96 kHz (umsindo professional, imingcele efana ifomethi lossless).

sphere kwesicelo

Manje, esinye isici endinganisweni AVCHD. Hlobo luni ifomethi kancane kuyaqondakala. Ake sibheke ezindaweni athandwa kakhulu uhlelo lwayo lokusebenza.

Ingasaphathwa kungenzeka ngokusebenzisa le ndinganiso mayelana nokudubula movie noma ngokuya ukucubungula ividiyo noma isignali alalelwayo, kungase kuqashelwe ukuthi isiqondiso main sokuthuthuka, ukuguqulwa kanye nokusetshenziswa ithelevishini digital isibe, ngokukhethekile, HDTV abamukelayo, iziteshi pay digital.

By the way, e-Brazil esifanayo, le ndinganiso isetshenziswa emhlabeni wonke amasevisi we-TV digital. ESouth Korea, ke lishumekwe uhlelo Digital Multimedia Sokusakaza, futhi inkonzo Japanese Fuji Ithelevishini NHK le ndinganiso elihlobene ne-ingxenye mobile emakethe.

iziphathi

Njengoba ojwayelekile, ukugcina ulwazi indlela ezinjalo kokucindezelwa ka ividyo ne-odiyo wekhodi usebenzisa ngemoto esiqinile isimo. Uma ekuqaleni kakhulu ekuthuthukeni kwale ejwayelekile isetshenziswa kuphela Blu-ray akwazi ukugcina noma abezindaba ezikhethekile AVCHD (8 cm), kodwa manje amafayela lokhu format kungenziwa kalula egcinwe hard drive noma nememori khadi, i-Memory Stick Pro ne-SD.

Umbuzo uwukuthi: kanjani kukhiqize noma uhlele izinto? Kukhona izindlela eziningana.

AVCHD: uvula?

Uma uhlelo isofthiwe ngokuya play, ekutholakaleni kwe amakhodekhi futhi decoders noma yisiphi isicelo ngesimo umdlali noma uhlelo ukubona ukwakheka isiqophi kalula.

In the version eyisisekelo, ungasebenzisa efanayo-Windows Media Player, noma okungenani umkhiqizo ezithakazelisayo ngokuthi VLC Media Player. Isimiso esinjalo ezivamile yevidiyo ngenhlanhla sinesikhundla okukhulu kunalokhu okujwayelekile Windows amathuluzi.

Njengoba ukwelashwa, kukhona ubunzima obuthile. Okokuqala, inkinga eyinhloko ukukopisha impahla ngekhamera efanayo noma AVCHD disc. uhlelo nefayela UDF 2.5 «ekspishkoy" ayisekelwe. Isixazululo elula ukulungisa inkinga ukufaka isofthiwe iphakethe ezengeziwe uNero InCD.

Ngaphezu kwalokho, amafayela ngokwabo ethumba ikhamera zingafakwa lwemibhalo STREAM, okuyinto kufihlwe lwemibhalo impande kudivayisi noma amafolda.

Ukuvulwa ngosizo amathuluzi professional efana Sony Vegas Pro noma enye into okuxoxwa.

Ngenisa video kule format Ungakwazi isikhombi ngisho like izicelo ukucutshungulwa komsindo ezifana Sony Sound Forge noma Adobe Audition CS.

Guqula AVCHD komunye format

AVCHD ukuze uthumele abanye nezakhiwo efundekayo, ngokuvamile besebenzisa converters isofthiwe ekhethekile, engatholwa namuhla, kakhulu ngendlela kunesidingo.

Isimiso jikelele kuyehla kuphela yokuthi, ukukhetha izinto ukuba ukuguqulela, futhi ucacise uhlobo uya khona idatha. In the izilungiselelo ungakwazi futhi usethe ukukhethwa kwevidiyo ezifanele futhi umsindo ukucutshungulwa amathuluzi.

esikhundleni umphumela

Lapha, empeleni, futhi konke ukwenzani AVCHD isiqophi ejwayelekile. Kuyini lokhu format futhi siyini izinga layo, kungcono ukuhlola ngqo lapho nokubheka izinto ezibonakalayo ku okufanayo flat-panel namathelevishini. Uma uqhathaniswa nezinye nezakhiwo ezikhona njengamanje, lokhu eliphezulu kakhulu, ngaphezu, it is hhayi Resource amakhamera ngenkani, amathelevishini, amakhompyutha noma amadivayisi eselula. By the way, indlela isiqophi kokucindezelwa upaka okokusebenza ukuze kunoma iyiphi ezigcina isikhala esiningi, njengoba Icebo laliwukuthi fanele none. Ngokuvamile - izinzuzo.
