AVI ukuba MKV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani ikhowudi i AVI ibe yi MKV ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho AVI kwaye umguquli uqhuba i-CRF-esekelwe kwakhona-ukukopela ukujolisa kwi-visually-lossless MKV imveliso (CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne MKV isiqulathi seefayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 ye-newer pipelines. Iifayili ze-AVI zingaphambili kunee-codecs ezitsha: lindele i-MPEG-4 Inxalenye ye-2 (DivX/Xvid), i-Motion JPEG okanye iifayili ezingenakucothayo ezingenakucothayo kunokuba i-H.264. I-MKV ayisebenzisi i-codec: H.264, HEVC, VP9 ne-AV1 ividiyo ihlala ikhululekile ecaleni kwe-AAC, FLAC, Opus, DTS okanye i-Dolby audio kwifayili enye.

I-AVI yevidiyo yam ibonisa imigca ye-comb kwi-movement - iya kuthatha into kwi-MKV?

Iya kwenza ukuba awuyi-deinterlace, kwaye AVI imixholo ihlala i-interlaced ngenxa yokuba ifomati ivela kwixesha le-broadcast ne DVD. Iiframes ezi-interlaced zigcina iindawo ezimbini eziphakathi-ubukhulu eziqhotyoshelwe kwishumi elinesihlanu sesibini; kwifowuni eqhubekayo-yokukhangela okanye imboniselo efunda njenge-horizontal combing nantoni na ehambayo. Yenza ukhetho lwe-deinterlace kwaye i-encoder igubungela iindawo kwi-frames ezipheleleyo eziqhubekayo phambi kokubhala i MKV. AVI yiMicrosoft's Audio Video Interleave, enikezelwe ngowe-1992 phezulu kwe RIFF chunk format - enye yezinto ezidala ezigcinwe zihlala zijikeleza.

I-AVI yam yokurekhoda ihlukaniswe ibe ziinxalenye ezilinganisayo - ngaba i-MKV inemida efanayo?

Hayi, kwaye le yenye yezona zizathu zilungileyo zokushenxisa. I AVI isiqulathi siqulethe ifayile enye esebenzayo ethe tyaba eyenza ushicilelo olude okanye oluphezulu-bitrate luqhube ngokuthe ngqo, oko kukuthi, kutheni ushicilelo oludala lufika njengenxalenye1, ingxenye2, ingxenye3. MKV ayinalo umda ofanayo, ngoko ke iinxalenye zinokudityaniswa kwakhona kwifayile enye eqhubekayo. I-AVI ayinakuxhaswa kwe-codecs ekutsha, i-frame rate etshintshayo, izihloko ezimfutshane ezimdaka okanye iifayile ezingaphezulu kwe-4 GB ngaphandle kwe-hacks, kwaye i-chunk nganye i-overhead ikhupha ifayili.

Ndingazifaka njani izihloko ezingaphantsi ezikhethiweyo xa ifayili ikwi MKV?

Ewe. AVI ayinayo i-soft-subtitle track esetyenziswayo, ngoko ke i-subtitles ye-AVI iqulethe into ekufuneka ikhutshwe kumfanekiso okanye ithunyelwe njengefayili ye-sidecar eyahlukileyo. MKV ithatha i-subtitles njenge-stream yabo ekhethiweyo, ngoko ke emva kokuguqula ungadibanisa i-SRT track imboniso ingatshintshwa, itshintshwe okanye iphinde iguqulwe.

Ingaba i MKV inkxaso yamachaphaza ophawu anjengoko AVI ayizange ikwenze?

Iyenza. MKV igcina izihloko njenge metadata yesiqulathi seefayili, ngoko ushicilelo olude lunokuqhubela phambili ngecandelo endaweni yokucoca ibar yokuqhubekeka. AVI ayinanto yokubeka loo nkcukacha, ngoko ukuba umthombo uthunyelwe ngoluhlu lwesihloko yayikwifayile ye sidecar - inikezele kuguquleli kwaye ibhalwe kwi MKV. I-MKV yindawo yokugcina ekhethiweyo kuba igcina iingoma zesandi ezingaphelelanga, izihloko eziphantsi ezicocekileyo, abaphawuli besiqendu kunye nobugcisa bokuqhobosha kwifayili enye.

Ingaba kufanelekile ukutshintsha i AVI yoshicilelo oludala ukuya kwi MKV?

Ukuba ufuna ukugcina into, ewe. AVI ibhekisa kuhlobo oludlulileyo lwezixhobo zevidiyo kwaye isoftware efunda i-video ihlala iphela kwifowuni, iziphene kunye nenkqubo yokusebenza. Ukushenxisa imifanekiso kwi MKV ngoku, ngelixa i-decoder ecocekileyo ikhona, kuhlukile phakathi kovimba onokuthi uvule kwiminyaka elishumi kunye noyena awukwazi.

Yeyiphi i-codec yevidiyo esetyenziswa yi-MKV yemveliso?

Ixhomekeke kwi MKV isiqulathi seefayili. I-MP4 imiselwe ukuba i-H.264 ukuze ixhase ukudlala okubanzi phakathi kweefowuni, iibrowser, kunye neSmart TVs. I-MKV imiselwe ukuba i-H.265 / HEVC ukuze ijikeleze i-half of the file size at equivalent quality. I-WebM imiselwe ukuba i-VP9. Iinketho eziphambili zibonisa ukhetho olucacileyo lwe-codec ukuba ufuna ukucima. MKV yi Matroska, isiqulathi esivuliweyo esidweliswe ngowe-2002 ngaphandle kokungasebenzisi ilayisensi okanye uthintelo oluphezulu olunokunqumla.

Ingaba umculo wam wesandi uya kuqhubeka uguquka AVI ukuya MKV?

Yes. When AVI and MKV share an audio codec (e.g. both carry AAC), audio is re-muxed with no re-encode — bit-identical. When the codecs differ, audio is transcoded to AAC / Opus / Vorbis depending on what the MKV container supports. Multi-track audio (commentary, alternate languages) is preserved.

Ndingagcina i-framerate yokuqala xa ndiguqula i-AVI iye kwi-MKV?

Ngokungagqibekanga ewe — i-24fps AVI ihlala i-24fps kwi-MKV; i-60fps AVI ihlala i-60fps. Ukuba ufuna ukuguqula umyinge (umzekelo, i-interlaced 29.97 → i-progressive 30, okanye i-60 → 30 yokukhuphela umda), ukhetho lobungakanani be-frame luphatha 3:2 ukutsala ezantsi, ukususa uthungelwano, kunye nokuqhekeka kwe-frame kwindlela efanayo yokukopela.

Ingaba ubungakanani befayili butshintsha njani ukusuka kwi AVI ukuya kwi MKV?

I-codec efanayo yoku-mux (AVI H.264 → MKV H.264 itshintsha kuphela isiqulathi seefayili): ubungakanani obufanayo. Utshintsho lwe-codec lunokutshintsha ngokumangalisayo: H.264 → H.265 luya kuquka ifayile kwinqanaba elifanayo lomgangatho obonakalayo; VP9 imalunga nokuthelekiswa; AV1 iquka enye i-20-30% kodwa ihamba phantsi ukukopela.

Ingaba ifayili MKV iyadlala kwi-iPhone, Android, kunye neSmart TVs?

MP4 / H.264 idlala ngokusemthethweni kwisixhobo ngasinye esitsha. MOV / H.264 idlala kwizixhobo zeApple kunye neTV ezininzi kodwa hayi rhoqo kwi-Android edala. MKV ifuna i-VLC kwi-iOS. WebM ikwi-browser-first. Iinketho eziphambili ziquka "ukulungelelanisa isixhobo" esimiselweyo esikhetha i-MKV codec / isiqulathi seefayili esikhuselekileyo so target yakho. I-MKV ayinaso nasiphi na isibonelelo sehardware esisemthethweni - iifowuni, iziphene kunye neeTV zihlala zifuna i-VLC okanye i-remux phambi kokuba zidlale.

Ithatha ixesha elingakanani ukutshintsha i-AVI yevidiyo yeyure enye ibe yi MKV?

I-Same-codec re-mux ikwindawo efutshane-imizuzu engama-30 ukuya kwengama-60 yefayili yeyure enye. I-codec epheleleyo iqhuba ngokuthe ngqo kwi-0.3-0.7x yobude bomthombo kwi-GPU yethu, ngoko ke i-1-hour AVI → MKV igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.
