MKV ukuba MPG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-MKV ibe yi-MPG ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho ye MKV kwaye umguquli uqhube i-CRF-esekelwe kwi-encoding ephindayo ebhekisa kwi-visually-lossless MPG imveliso (i-CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne MPG isiqulathi-zifayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 yee-pipelines ezintsha. MKV yi-codec-agnostic: H.264, HEVC, VP9 ne-AV1 ividiyo ihlala ikhululekile ecaleni kwe-AAC, FLAC, Opus, DTS okanye i-Dolby audio kwifayili enye. Okuqulethwe yi-MPEG-1 okanye i-MPEG-2 ividiyo ene-MP2 umsindo; ukudibanisa nokwakhiwa kwe-GOP kufana ne-.mpeg ifayili.

Yintoni eyenza i-subtitle tracks kwifayili yam MKV?

Ayikwazi ukuhlala ikhethiwe, kuba MPG ayinayo i-soft-subtitle stream ukubeka i-subtitles. Zikhona iindlela ezimbini zokuphuma: ukutshabalalisa kwividiyo ngexesha lokuguqula, okwenza ukuba zihlala zihlala kwaye zingatshintshwa, okanye urhweba ngaphandle njenge.srt eyahlukileyo ecaleni kwe MPG ukuze umdlali alayishe. Umguquli uthetha ukuba yintoni eyayenza kunokuba ikhuphe ngokucokisekileyo. MPG ifumana yonke i MPEG-2 imida - i-bitrate enzima, uthungelwano, akukho sihloko esicocekileyo - kunye nokungaqhelekanga kweendawo ezimbini zokukhupha ifomati enye.

Kutheni ndiyiguqula i MKV ibe yifomati edala njenge MPG?

Kuba isixhobo esininzi sekhompyutha asizange sifunde nantoni na entsha kwaye asizukufunda. Abadlali be DVD, iiyunithi zemoto eziphambili, iimo zokubukela i-camcorder, imboniselo yeshishini kunye nezixhobo ezininzi zosasazo lweemveliso zixhasa MPG kwaye akukho nto enye. Uguqulelo luya kugqiba inqanaba ezantsi kwimpumelelo, ithengiswe ukutshintshela ukusebenza kwisixhobo esingakho enye indlela yokukhetha. MPG yi DVD yoshicilelo lwesoftware yolubanzi, i-camcorders edala kunye nezixhobo zokusasaza ukutya ziyazi, ngoko ihlala isetyenziswa kwezi ntambo.

Yeyiphi i-codec yevidiyo esetyenziswa yi-MPG?

Ixhomekeke kwi MPG isiqulathi seefayili. I-MP4 imiselwe ukuba ibe yi-H.264 ukuze ixhase ukudlala okubanzi phakathi kweefowuni, ii-browser, kunye ne-Smart TVs. I-MKV imiselwe ukuba ibe yi-H.265 / HEVC ukuze ilinganise nengxenye yobungakanani befayili kwinqanaba elifanayo lomgangatho. I-WebM imiselwe ukuba ibe yi-VP9. Iinketho eziphambili zibonisa ukhetho olucacileyo lwe-codec ukuba ufuna ukucima. I-MPG ifana nenkqubo ye-MPEG ejikelezayo njenge-.mpeg — uluhlu lweeleta ezintathu luyi-DOS-era truncation, hayi ifomati eyahlukileyo.

Ingaba umculo wam wesandi uya kuqhubeka uguquka ukusuka kwi MKV ukuya kwi MPG?

Ewe. Xa MKV ne MPG zibelana nge-codec yesandi (umzekelo, zombini zithabatha i-AAC), isandi siphinda sixutywe ngaphandle kokubuyisela ukukhowuda - i-bit-identical. Xa ii-codecs zihlukile, isandi siguqulwa kwi-AAC / Opus / Vorbis kuxhomekeke ekubeni i-MPG ixhasa ntoni. I-audio enezithotho ezininzi (iingxelo, iilwimi ezitshintshiweyo) igcinwa.

Ndingagcina i-framerate yokuqala xa ndiguqula i-MKV ibe yi-MPG?

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

Ubungakanani befayili butshintsha njani ukusuka kwi MKV ukuya kwi MPG?

I-codec efanayo yokuphinda-phinda (MKV H.264 → MPG H.264 itshintsha kuphela isiqulathi seefayili): ubungakanani obufanayo. Utshintsho lwe-codec lunokutshintsha ngokumangalisayo: H.264 → H.265 luya kuquka ifayili kwinqanaba elifanayo lomgangatho wokubona; VP9 imalunga nokuthelekiswa; AV1 icima enye i-20-30% kodwa ihamba phantsi ukukopela.

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

MP4 / H.264 idlala ngokusemthethweni kwisixhobo ngasinye esitsha. MOV / H.264 idlala kwizixhobo ze-Apple 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-MPG codec / isiqulathi esikhuselekileyo senjongo yakho.

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

I-Same-codec re-mux ikwindawo efutshane-imizuzu engama-30 ukuya kwengama-60 yefayili yeyure enye. I-codec epheleleyo ephinda-ikhowudi iqhuba malunga nexesha lomthombo we-0.3-0.7x kwi-GPU yethu, ngoko ke i-1-iyure MKV → MPG igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.

Yintoni ubukhulu bomfanekiso oxhaswayo kwi MKV ukuya kwi MPG?

Ukuza kuthi ga kwi-8K (7680×4320) kwi-premium plans. Ukuguqulwa simahla kugqityiwe kwi-4K (3840×2160) ngumda wobungakanani befayili nganye. I-HDR metadata (HDR10, HDR10+, Dolby Vision xa ikhona) iqhutywa apho zombini i MKV ne MPG iinqanawa zixhasa khona.

Ingaba i-MKV yevidiyo yam ifihlakeleyo ngexesha liguqulwa libe li MPG?

Ewe. Iifayili zevidiyo ezilayishwe phezulu ziqhubekekiswa kubasebenzi abakhethekileyo, azisoloko zijongwa ngumntu, azisoloko zidweliswe kwisikhombisi, kwaye zicinywa kwimizuzu embalwa emva kokuphela. Ifestile yokugcina ibhalwe kwi /privacy/ kwaye asipapashi naziphi na iziqu zesifundo ezivela kubasebenzisi abalayishwe phezulu.

Ndingatywina, ndiyimise, okanye ndiyijikelezise ngexesha lokuguqulwa kwe MKV ukuya kwi MPG?

Ayikumgangatho ofanayo — sebenzisa /video-trim/ okanye /video-cutter/ ukucima kuqala, emva koko qhuba uguqulelo MKV → MPG. Ukudibanisa ukusika nokutshintsha kukhawulezayo kunekubuyisela kwakhona ikhowudi yonke i MKV ukushiya kuphela imifanekiso engasebenziyo.
