AVCHD - luni format? Advanced Video codec High Definition - Advanced Video codec High Definition

abalandeli ukubukela umgangatho ophezulu ividiyo kunye nesisombululo kakhulu esoloko ijongana nefomathi AVCHD. Yintoni na le fomati nendlela iyahluka ukusuka wadala zonke phambi ngoku kwaye ziza kuqwalaselwa. Ukongeza apho, ingqwalasela eyodwa iya kunikwa ubuchwepheshe ngokwayo kunye program ivumela ukuba ukusebenza kunye nomgangatho AVCHD entsha.

AVCHD: olunjani format?

Nangona ngelo xesha kuza yevidiyo, isandi lidlala indima. Wona ukuwufunda lo unciphiso kongoma leswaku phambili Video codec High Definition (i-Advanced Video codec High Definition).

Lo mgangatho iteknoloji entsha kwaye usebenzisa ividiyo ucinezelo esekelwe ucinezelo MPEG4 aVc / H.264.

Ezinye iindlela nokurekhodwa kwevidiyo, umzekelo, MPEG2 umgangatho omtsha ulahlekelwa ngokucacileyo, ngokuba AVCHD Mhlanguli arcade games kwinqanaba 720p, 1080p, kunye 1080p, kwaye kunciphise nemfuno ukugcinwa data.

History ezahlukeneyo

Ukuba ujonga kwimbali yophuhliso, AVCHD ukurekhodwa ifomati ekuqaleni wadala nje uhlobo olunye ukuya HDV umgangatho ivuma, apho de kutshanje elaye loyisa ngayo abathengi kunye nobungcali khamera.

Kuba okokuqala umgangatho entsha yaphuhliswa ngo-2006 corporation Matsushita Electric Industrial Co. Ltd., nto leyo ke ngenkuthalo ubambisene enye yeenkokheli kummandla photo, ividiyo kunye odiyo - ihlabathi-owaziwayo Panasonic. Emva koko sebenzisa ngefomathi entsha lancitshiswa kuphela ukuya iikhamera.

Kwaba kuphela ngo-2008, ngentsebenziswano Sony Corporation ubhengeze into eqinileyo-karhulumente ukurekhodwa nobuchwepheshe, nto leyo eyakhokelela ekubeni imbonakalo khamera yokuqala professional.

ifomati sokuqala ngokwawo phezu ixesha unenzondelelo utshintsho (ziye iinguqulelo eziliqela kulo ngeparameters ezahlukeneyo kunye nokwenziwa khona). Ukuza kuthi ga ngoku, umahluko phakathi kulandelayo:

• AVCHD Lite - format lite enesisombululo lemiqolo 720 kuphela kunye rhoqo lomdlalo-24, 50 okanye 60 fps;
• AVCCAM - format video yobungcali esekelwe kwi-3 matrix-CCD-isivamvo wokuba isantya sebhithi ukurekhoda 24 Mbit / s, enxulumene ngaphesheya XLR umbhobho igalelo kunye ivenkile kuzimele phezu SSDs;
• NXCAM - format «acocekileyo» Sony, ekwaziyo zokurekhodisha kwevidiyo umgangatho 720p, 1080p, kunye 1080i, kodwa ukusebenza ngezinga isakhelo ka 24, 25 no-30 fps;
• AVCHD 3D / Progressive - format 2011 uhlaziyo kwinguqulelo 2.0, ixhasa ividiyo eyodwa ukurekhoda kunye 1080p / 50-60fps iparameters).

codecs ividiyo wasebenzisa

Yona le vidiyo, wasebenzisa codecs kunye STB ukuze becala zisekelwe MPEG-4 technology ucinezelo, nangona kunjalo, ezimbalwa ezinye iinketho.

Faka ividiyo afanayo zaye awasebenzi XP. Ukuze wenze oku, wena kudingeka nje ukuba ufumane uguqulelo yempahla ezithandwayo K-Lite zakutshanje. Kodwa inkqubo ufakelo endaweni yeseti komgangatho ocetywayo "Setup" ikhusi, khetha Advanced kwaye ujonge izinto ezininzi thaca kuluhlu.

Ukongeza, codecs yokuzonwabisa installable Windows XP okanye ngaphezulu kwesikhundla kwenkqubo zingahlulwa ngokweendidi ezimbini - AVCHD-SD (inkcazelo standard) kunye AVCHD-HD (High Definition). Ngokusekelwe kule, singakwazi ukunciphisa iimpawu othelekiso zombini migangatho.

STB audio

Namashishini audio akukho ilula kakhulu. Isiseko Ukuguqulwa uphawu wazibeka iiteknoloji ezimbini eziphambili - eqondile PCM kunye Dolby Digital. Noko ke, isandi, abantu abaninzi ngokucacileyo musa ukuqonda umahluko phakathi umgangatho kunye nokusasazwa odiyo.

Ngoko ke, ngenxa yezizathu ezithile, abanye abasebenzisi kubiza umgangatho ifomati isandi recording 5.1, 7.1 okanye 8.1. Khumbula: akukhona umgangatho, kodwa kuphela ithuba lonikezelo uphawu kulo mba othe.

U nga tshinela isifaniso izixhobo ebizwa crossovers. Basenokwabelana rhoqo uze ubabuze ukuba izithethi ezifanelekileyo. Ukuba nabani ukhumbula, kumaxesha Soviet zavelisa ikholam Radiotehnika S Series kunye lenjongo evulekileyo umphandle, apho ezantsi cone ephantsi-rhoqo ekhoyo phakathi - midrange kunye top - tweeter.

Siqhagamshelwe crossover wokukhulisa eyithumela ethile uluhlu frequency elihambisana iimpawu isithethi ixilongo.

Kodwa ke ngokwalo ukwabiwa bayawarhawula-isandi esetyenziswayo isici engezansi. Umgangatho emanyelwayo kumiselwa isantya sebhithi kunye novavanyo rhoqo. Kulo mzekelo, i-odiyo unako idlalwe umva kunye iimpawu kwinqanaba 320 kbit / s kunye 96 kHz (isandi yobungcali, imida ezifanayo lossless format).

enkulu isicelo

Ngoku, nomnye umgangatho AVCHD. Loluphi uhlobo format siyaqondakala kancinci. Makhe sijonge iinkalo uthandwayo isicelo sayo.

Singasathethi amathuba usebenzisa lo mgangatho ngokubhekiselele iimovie zokudubula okanye ngokwemiqathango yokujongwa yevidiyo okanye umqondiso audio, ukuze kuqwalaselwe ukuba kwicala ephambili yophuhliso yayo, ukulungiswa kunye nokusetyenziswa umabonakude wedijithali iye, ingakumbi, balwamkele HDTV, digital channels pay.

Hi ndlela leyi, ku Brazil enye, lo mgangatho isetyenziselwa ehlabathini lonke iinkonzo TV zedijithali. EMzantsi Korea, oko elungiselwe inkqubo Digital Multimedia Broadcast, kunye nenkonzo Japanese Fuji umabonakude NHK le nemigangatho enxulumene abangakwaziyo yemobile emarikeni.

zenethiwekhi

Njengomthetho jikelele, ukugcina ulwazi indlela enjalo ucinezelo ividiyo kunye audio khowudi usebenzisa eqinileyo-state drives. Ukuba ekuqaleni kuphuhliso lo mgangatho isetyenziswa kuphela idiski Blu-ray okanye AVCHD akhethekileyo kumajelo eendaba (8 cm), kodwa ngoku iifayile le fomati ukuba lula egcinwe kwi-hard drive okanye nememori khadi, Memory Stick Pro kunye SD.

Umbuzo: ukuzala okanye ukuhlela izinto njani? Kukho iindlela ezininzi.

AVCHD: uvula?

Ukuba inkqubo software ngokwemiqathango umdlalo, kuxhomekeke ekufumanekeni codecs kunye STB nasiphi na isicelo ngohlobo umdlali okanye inkqubo ukuqaphela ifomati wevidiyo lula.

In kwinguqulelo ezininzi ezingundoqo, ungasebenzisa i efanayo Windows Media Player, okanye ubuncinane yimveliso umdla ekuthiwa VLC Media Player. Loo inkqubo eqhelekileyo yevidiyo, ngokuzenzekelayo, kukho umthamo omkhulu kakhulu izixhobo Windows eqhelekileyo.

Ke ukuba unyango, kukho ezinye iingxaki. Okokuqala, le ngxaki iphambili ukukopa izinto ngekhamera efanayo okanye AVCHD idiskhi. inkqubo ifayile yemidiya UDF 2.5 «ekspishkoy 'ayixhaswanga. Isisombululo lula ukulungisa ingxaki ukufaka iphakheji software eyongezelelweyo uNero InCD.

Ukongeza, iifayile ngokwabo zifakwe kwi camera nga zifakwe kuvimba weefayili komlambo, nto leyo lufihlwe ingcambu lawulo isixhobo okanye sub-eneenkcukacha.

Ukuvulwa ngoncedo izixhobo afana Pro Sony Vegas okanye into enye into azixoxwa.

Ngenisa ividiyo kule fomati Unga nakwiprogram ngathi izicelo processing odiyo ezifana Sony Sound Ukuqhubekela okanye Adobe nokuhlola CS.

Guqulela AVCHD kwenye ifomati

AVCHD batshintshelwe kwezinye iifomati ayifundeki, ngokuqhelekileyo kusetyenziswa converters software eyodwa, lexi kumekaka namhlanje, kangangoko kuyimfuneko.

Umgaqo ngokubanzi yehliswe kuphela kukuba, ukukhetha izinto ukuba lokuguqula, uze ucacise uhlobo data kuyo. In the izilungiselelo nawe Ungakwazi nokuseta kukhethwe ividiyo efanelekileyo kunye nezixhobo processing odiyo.

kunokuba nesiphumo

Apha, okunene, yaye yonke into yokwenza nomgangatho AVCHD yevidiyo. Yintoni na le fomati kwaye yintoni na umgangatho walo, kungcono ukuba ukuhlola ngqo xa ujonga izinto ezikwi-shini ezimcaba-panel efanayo. Xa kuthelekiswa nezinye iifomathi ezikhoyo ngoku, oku umgangatho ophezulu, ukongeza, noko izinto eziluncedo, iikhamera ngenkani, umabonwakude, ikhompyutha okanye izixhobo mobile. Hi ndlela leyi, indlela ividiyo ucinezelo Imiqulu umbandela ukuze ukuba nawuphi na izinto ezigcina up isithuba kakhulu, njengoko ingcamango yayikukuba namnye. Ngokubanzi - ezinye iingenelo.
