AVCHD - ichi chimiro chei? Yakawedzerwa Vhidhiyo Codec High Definition - Yakagadziriswa High Definition Video Codec

Vavhidhiki vakawanda vanotarisa vhidhiyo yepamusoro-soro nekugadzirisa kazhinji vanosangana nemafomu eAVCHD. Iyo yakarongeka sei uye yakasiyana sei nezvose zvakasikwa kare, zvino zvichataridzirwa. Mukuwedzera, kunyatsotarisa kuchabhadhara kune teknolojia iyo pachavo uye zvirongwa zvinobvumira kushanda nehutano hweVARCHD itsva.

AVCHD: ichi chimiro chei?

Kunyangwe panguva yatinenge tichitaura pamusoro pevhidhiyo, inzwi iri pano rinotora basa rinokosha. Izvozvinyorwa zvakafanana zvekuderedzwa uku zvinoreva zvakananga kune video yakakurumbira codec yepamusoro kusarudza (Advanced Video Codec High Definition).

Iyi mitemo inenge ichitsva uye inoshandisa vhidhiyo compression teknolojia inobva pa MPEG4 AVC / H.264 kudzvinyirira.

Zvimwe mavhidhiyo ekurekodha kwevhidhiyo, somuenzaniso, MPEG2 kusvika kumutambo mutsva inorasikirwa nekujeka, nokuti AVCHD inopa unhu hwakanakisisa pa 720p, 1080p uye 1080p, uyewo yakaderedza zvido zvekuchengetedza deta.

Nhoroondo yezvinoitika uye zvakasiyana-siyana

Kana iwe ukatarisa nhoroondo yekufambisa, mafomu ekurekodha aAVCHD aive akaumbwa seimwe nzira yeHVV neDV, izvo zvakasvika munguva pfupi yapfuura mumusha nemakambani emakhamera mavhidhiyo.

Mamiriro matsva aya akatanga kutanga muna 2006 naMatsushita Electric Industrial Co., Ltd. Ltd., iyo panguva iyoyo yakashanda pamwe chete nemumwe wevatungamiri mumunda wemufananidzo, video uye audio - nyika inozivikanwa nekambani Panasonic. Zvadaro kushandiswa kwemutauro mutsva kwakanga kwakagadzirirwa chete kumavhidhiyo makamera.

Uye mugore ra2008 pamwe chete nekambani Sony yakatanga kuzivikanwa teknolojia yekusimudzira-nyika kutumira, izvo zvakaita kuti kuve kwekutanga kwekamberi makcorders.

Izvo zvakafanana maitiro akave nekugadziriswa kwemashure (nguva dzakasiyana-siyana dzacho dzakaratidzwa nemararamiro akasiyana uye zvirongwa). Kusvika iye zvino, zvinotevera zvinoratidzika:

• AVCHD Lite - miviri isinganzwisisiki nechisarudzo chemigwagwa 720 chete uye chiyero chemupfigiro we 24, 50 kana 60 fps;
• AVCCAM - maitiro ekugadzirwa kwevhidhiyo makamera zvichienderana ne-3-matrix CCD sensor, achibvumira kutora ne bitrate ye 24 Mbit / s, kubatanidza maikrofoni kuburikidza nekupinda kweXLR nekuchengetera mavhidhiyo pamagetsi akaoma;
• NXCAM inoratidzika "yakachena" yakabva kuna Sony, iyo inokubvumira kuti utore mavhidhiyo ehupamhi 720p, 1080p uye 1080i, asi usingashandisi nepurogiramu ye 24, 25 ne30 fps;
• AVCHD 3D / Progressive - inoshandura mararamiro e 2011 kuenda ku version 2.0, inotsigira kupfura kwevhidhiyo yakagadziriswa nemaparamendi 1080p / 50-60fps).

Vhidhiyo yevhidhiyo codecs

Kana iri vhidhiyo, ma codecs uye mabodhadhi anoshandiswa zvinowanzovakirwa paIndaneti-MPEG-4, asi vane mamwe mashoma.

Isai iyo yemavhidhiyo codec ye XP basa haisi. Kuti uite izvi, iwe unongoda kuwana shanduro yemazuva ehurukuro yakakurumbira yeK-Lite. Asi pakugadziriswa kwekuisa, pane nzvimbo yakagadzirirwa ne "Setup Wizard", unofanirwa kusarudza yakasimudza uye kuisa zvinhu zvose muurongwa.

Pamusoro pezvo, mavhidhiyo akaiswa mavhidhiyo eXP kana maitiro epamusoro-soro anogona kugoverwa muzvikamu zviviri - AVCHD-SD (kusagadziriswa kwakakwana) uye AVCHD-HD (yakasarudzwa). Kufambira mberi kubva pane izvi, zvinokwanisika kugovera kuenzanisa kwezvinhu zvose zviri zviviri.

Vodhidhiyumu audio

Nehurukuro, mamiriro ezvinhu haasi nyore. Nheyo yechiratidzo chekushandura inobva pamichina mbiri huru - Linear PCM neDolby Digital. Zvisinei, maererano nezveshoko, vazhinji vashandisi havanyatsonzwisisi musiyano pakati pehupenyu nehuwandu.

Saka, nokuda kwechimwe chikonzero vamwe vashandisi vanoshevedza hutano hwetsika yekurekodha mafaira 5.1, 7.1 kana kunyange 8.1. Yeuka: iyi haisi yehutsika, asi inokwanisa chete kuparadzira chiratidzo munzira ye panoramic.

Iwe unogona kupa mhizha kumagetsi anonzi crossovers. Vanogona kuparadzanisa mararamiro ezvo ndokuvatungamirira kune zvakakodzera simba. Kana mumwe munhu achiyeuka, munguva dzeSoviet Radiotehnika mutsara S s series dzakabudiswa nebhokisi rakasununguka panze, iyo iyo yakaderera yakawandisa yakave iripo, pakati pepakati-pakati yakapararira yaiva pakati, uye tweeter yakanga iri pamusoro.

Nhamba yakabatanidzwa kumugadziridzo inogona kutungamira imwe nguva yekutarisa kusvika kune zvakakwikwidzirwa zvipikisi.

Asi maererano nekuparidzirwa kweruzhinji rwakapoteredza rinoshandiswa pane panoramic characteristic. Uye hutano hwehutori hwakatsanangurwa nehuwandu hwekuita uye sampuli yezinga. Mune mhaka yedu, audio inogona kudzokororwa nemafungiro pa 320 Kbps uye 96 kHz (unyanzvi hwehupfumi, hwakafanana nehupenyu husina kurasikirwa).

Chikamu chekushandiswa

Iye zvino chimwe chimwe chinhu, maererano neAVCHD yakazara. Iko rudzi rwemhando dzakatove zvishoma zvakajeka. Ngatitarise pane nzvimbo dzinonyanya kuzivikanwa zvekushandiswa kwayo.

Tisingatauri mukana wekushandisa chiyero ichi chevhidhiyo kana maererano nemavhidhiyo kana mazwi ekugadziriswa kwemashoko, zvinogona kuonekwa kuti nhungamiro huru mukurudzirwa kwayo, kuchinjwa uye kushandiswa kwave kwakava terevhizheni yemudhidhiyo, kunyanya, HDTV-vanogamuchira makirasi e digital.

Nenzira, muBrazil imwecheteyo muyero uyu unoshandiswa zvachose kune yese yese yeTV. MuSouth Korea, yakaiswa muhurongwa hweDynamic Multimedia Broadcast, uye basa reJapan reFiji Television neHNK chiyero ichi chinobatanidzwa nechikamu chemafoni chemusika.

Media

Kazhinji, kuti uchengetedze ruzivo nenzira iyi yevideo compression uye audio encoding, zvakasimba zvinotya zvinoshandiswa. Kana pakutanga kwekuvandudzwa kwemuenzaniso uyu Blu-ray discs chete kana mavhidhiyo akasiyana eAVCHD (8 masentimita) akashandiswa, mazuva ano mafaira akadaro anogona kuchengetedzwa nyore nyore kuDynamic drive kana kubviswa Memory Stick Pro kana SD makadhi mememori.

Mubvunzo ndewokuti: sei kubereka kana kuchinja zvinhu zvakadaro? Kune nzira dzakawanda dzeizvi.

AVCHD: chii chokuzarura?

Kana isu tichitaura pamusoro pee software maererano nekutamba, zvakapiwa apo pane codecs uye mazadziro akaiswa, chero sarudzo iri mufananidzo wemuteereri kana purogiramu yemavhidhiyo ichaona fomu pasina dambudziko.

Muchikamu chepakutanga, iwe unogona kushandisa imwecheteyo Windows Media Player kana chimwe chinhu chinonakidza chinonzi VLC Media Player. Purogiramu yakafanana yakadai yevhidhiyo, nenzira, ine hukuru hukuru hunoenzaniswa nehuwandu hweWindows tool.

Nekugadzirisa, pane zvimwe zvinetso. Chokutanga, dambudziko guru nderekunyora mashoko acho kubva kumera imwechete kana disc disc AVCHD. Ifaira system ye UDF 2.5 mhizha haisi kutsigirwa ne "kupera". Nzira yakanakisisa yekugadzirisa dambudziko iri ichange iri kuiswa imwe Nero InCD yeprojekti.

Mukuwedzera, mahwendefa akabatwa pane khamera anogona kuwanikwa mumutauro we STREAM, uyo wakavanzwa mumutsetse wemudziyo wekushandisa kana zviduku.

Uye kuvhura nebatsiro rwezvigadzirwa zvehupfumi seSy Ve Ve Pro kana chimwe chinhu hachina kukurukurwa zvachose.

Itai vhidhiyo yeiyo fomu inogona kunyange purogiramu yakafanana nekushandiswa kwekutamburwa kwemazwi akadai saSon Sound Forge kana Adobe Audition CS.

Shandura AVCHD kune imwe maitiro

Kushandura AVCHD kune mamwe mavara akaoneka, sekutonga, mapurogiramu anokosha ekushandura anoshandiswa, izvo zvaunogona kuwana nhasi, zvose zvaunoda.

Izwi guru rinongoda kusarudza zvinhu zvinoshandurudzwa uye kutsanangura iyo yekupedzisira yedhipei. Muchigadziriro, unogonawo kusarudza yakakodzera video neyodhidhi yekugadzira.

Panzvimbo yehuwandu

Pano, chaizvoizvo, uye zvose zvine chokuita nevhidhiyo yeVideo AVCHD. Rudzi rwemhando yei uye huri hupi huri nani, zviri nani kuti uongorore zvakananga kana uchitarisa mashoko pane imwe chete yepaTV-panel. Kuenzaniswa nemamwe maitiro akange aripo, ichi ndicho chinonyanya kukoshesa, uyezve, hachisi kuomesa zvakanyanya pfuma yekamera, maTV, makombiyuta kana kunyange zvigadzirwa zvefoni. Nenzira, iyo vhidhiyo inoshandiswa purogiramu inotakura zvinhu kuitira kuti ive nzvimbo yakawanda pane chero sarudzo yekuchengetedza , sezvaifanirwa, haina kubata. Pakati pese, pane zvimwe zvinobatsira.
