3GP ukuba MKV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani ikhowudi i 3GP ibe yi MKV ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho 3GP 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. I-3GP igcina i-H.263 okanye i-MPEG-4 Inxalenye ye-2 yevidiyo ene-AMR yesandi sokuthetha esinomqolo omfutshane, zonke zilungelelaniswe kwi-bitrate encinci kunekhwalithi. 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.

Ndingazifaka njani izihloko ezingaphantsi ezikhethiweyo xa ifayili ikwi MKV?

Ewe. 3GP ayinayo i-soft-subtitle track esetyenziswayo, ngoko ke i-subtitles ye-3GP 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 igcina ngaphezulu kwengoma enye yesandi?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe 3GP. MKV iphatha yonke imijelo yesandi njengento ephambili, ngoko udidi lwesivakalisi sokuqala, i-dub kunye nomlawuli wengxelo ingaphila kwifayile enye nomdlali otshintshela phakathi kwabo kwisicelo. I-MKV yindawo yokugcina ekhethiweyo kuba igcina iingoma zesandi ezingaphelelanga, izihloko eziphantsi ezicocekileyo, abaphawuli besiqendu kunye nobugcisa bokuqhobosha kwifayili enye.

Ingaba i MKV inkxaso yamachaphaza ophawu anjengoko 3GP ayizange ikwenze?

Iyenza. MKV igcina izihloko njenge metadata yesiqulathi seefayili, ngoko ushicilelo olude lunokuqhubela phambili ngecandelo endaweni yokucoca ibar yokuqhubekeka. 3GP ayinanto yokubeka loo nkcukacha, ngoko ukuba umthombo uthunyelwe ngoluhlu lwesihloko yayikwifayile ye sidecar - inikezele kuguquleli kwaye ibhalwe kwi MKV.

Ingaba i MKV iyaqhubeka idlala ngokulula kwifowuni okanye kwiTV?

Ingaba ayikwazi. 3GP ikhowudiwe yisilicon ekhethekileyo kwifowuni, iitablethi kunye neeTV, nto leyo eyenza ukuba idlala ngaphandle kokutyibilika kwebhetri. MKV ihlala ibuyela umva kwisoftware yokukhowudi kwihardware efanayo - ubunzima be CPU obuphezulu, isixhobo esishushu, kunye neeframes ezikhuphekayo kwi-4K material. Kwisixhobo esimiselweyo, 3GP yindawo ekhuselekileyo yokugcinwa ehlala kuyo. I-MKV ayinaso nasiphi na isibonelelo sehardware esisemthethweni - iifowuni, iziphene kunye neeTV zihlala zifuna i-VLC okanye i-remux phambi kokuba zidlale.

Zonke ii 3GP ne MKV ziibhokisi ezitsha — yeyiphi endingayenza?

Gcina naziphi na izilinganiso apho ifayile isiya khona, kuba akukho nto ingcono kwingcambu. Enye yazo ezimbini iyenziwe ukudlala uhambelana kunye nenye yokugcina konke ifayile ingaquka, kwaye barhweba nganye nganye ngokuchanekileyo ngaphaya komgca. Impendulo esebenzayo yeelayibrari ezininzi kukugcina kwibhokisi enamandla yomsebenzi kwaye urhwebe ngaphandle kwinye ehambelanayo kwisicelo. Iifayile ze-3GP zincinci kwaye ziyi-decode kwizixhobo zekhompyutha ezibuthathaka kakhulu ezikwaziyo ukucinga, nto leyo eyenza ukuba ifowuni ezinomtsalane kunye nezixhobo zefowuni eziphantsi ziphinde zirekhode.

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 3GP ukuya MKV?

Ewe. Xa i-3GP ne-MKV zibelana nge-codec yesandi (umzekelo, zombini zithabatha i-AAC), isandi siphinda sixutywe ngaphandle kokuphinda sikhowudi - i-bit-identical. Xa ii-codecs zihlukile, isandi siguqulwa kwi-AAC / Opus / Vorbis ngokuxhomekeka kwinto exhaswa ngumgqomo we-MKV. I-audio enee-tracks ezininzi (uphawulo, iilwimi ezitshintshiweyo) igcinwa.

Ndingagcina i-framerate yokuqala xa ndiguqula i-3GP iye kwi-MKV?

Ngokungagqibekanga ewe — i-24fps 3GP ihlala i-24fps kwi-MKV; i-60fps 3GP 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 3GP ukuya kwi MKV?

I-codec efanayo yoku-mux (3GP 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.

Ithatha ixesha elingakanani ukutshintsha i-3GP 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 3GP → MKV igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.
