MPG ukuba MP4 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-MPG ibe yi-MP4 ngaphandle kokubuyisela umbhalo ofihlakeleyo wevidiyo?

Xa i MPG ne MP4 iziqulatho zingathatha zombini i-codec efanayo (H.264, H.265, VP9, AV1), umguquli ubuyela umva kwi-remux: imijelo ephambili ikhopiwe i-byte-nge-byte kwi MP4 isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB MPG kwi MP4 ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. Okuqulethwe yi-MPEG-1 okanye i-MPEG-2 ividiyo ene-MP2 umsindo; ukudibanisa nokwakhiwa kwe-GOP kufana ne-.mpeg ifayili. I-MP4 eninzi eluhlaza yi-H.264 yevidiyo enesandi se-AAC; isiqulathi sigcina ngokusemthethweni i-HEVC, i-AV1 ne-VP9.

I-MPG yevidiyo yam ibonisa imigca ye-comb kwi-movement - iya kuthatha into kwi-MP4?

Iya kwenza ukuba awuyi-deinterlace, kwaye MPG 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 MP4. I-MPG ifana nenkqubo ye-MPEG ejikelezayo njenge-.mpeg — uluhlu lweeleta ezintathu luyi-DOS-era truncation, hayi ifomati eyahlukileyo.

Ndingazifaka njani izihloko ezingaphantsi ezikhethiweyo xa ifayili ikwi MP4?

Ewe. MPG ayinayo i-soft-subtitle track esetyenziswayo, ngoko ke i-subtitles ye-MPG iqulethe into ekufuneka ikhutshwe kumfanekiso okanye ithunyelwe njengefayili ye-sidecar eyahlukileyo. MP4 ithatha i-subtitles njenge-stream yabo ekhethiweyo, ngoko ke emva kokuguqula ungadibanisa i-SRT track imboniso ingatshintshwa, itshintshwe okanye iphinde iguqulwe.

I MPG yam inezinto ezininzi ezidlala umculo - ngaba zonke ziya kuhlala zikhona kwi MP4?

Ayithembekanga. MPG igcina imijelo emininzi yesandi njengemizila yohlobo lokuqala, kodwa MP4 uxhaso lokudlala ngaphezulu kwemizila yokuqala ayihambelani, ngoko abadlali abaninzi baya kutyhila kuphela enye. Khetha imizila oyifunayo phambi kokuguqula; abanye bangcono ukutywina kwifayile zabo ezikhethekileyo kunokuba bashiye kwisiqulathi seefayili esifihlayo. MPG yi DVD yoshicilelo lwesoftware yolubanzi, i-camcorders edala kunye nezixhobo zokusasaza ukutya ziyazi, ngoko ihlala isetyenziswa kwezi ntambo. I-MP4 ixhasa kuphela ifomati enye ethandwayo yesihloko esingaphantsi (mov_text), kwaye i-multi-track audio ayithembeki ngaphandle kwee-desktop players.

Ingaba i MP4 iyadlala kwisikhangeli xa i MPG ayiyidlala?

Ewe, kwaye oko kuqhelekileyo isizathu esipheleleyo sokuguqula. A MPG efakwe kwiphepha le web okanye ibonisa umdlali olahlwayo okanye iforce ulwaleko, kuba ibrowser ayithuthinga i decoder kuyo. MP4 idlala kwilayini esuka kwi HTML5 eqhelekileyo isixhobo sevidiyo ngaphandle koplugin kwaye akukho sicelo sengaphandle. I-MP4 yindawo ekhuselekileyo yokunikezelwa kweenkqubo ezifumanekayo - yonke ifowuni, ibrowser, i-console, umhleli kunye neSmart TV eyenziwe kwiminyaka elishumi edlulileyo idlala ngaphandle kwesoftware engaphezulu.

Ingaba kufanelekile ukutshintsha i MPG yoshicilelo oludala ukuya kwi MP4?

Ukuba ufuna ukugcina into, ewe. MPG ibhekisa kuhlobo oludlulileyo lwezixhobo zevidiyo kwaye isoftware efunda i-video ihlala iphela kwifowuni, iziphene kunye nenkqubo yokusebenza. Ukushenxisa imifanekiso kwi MP4 ngoku, ngelixa i-decoder ecocekileyo ikhona, kuhlukile phakathi kovimba onokuthi uvule kwiminyaka elishumi kunye noyena awukwazi. MPG ifumana yonke i MPEG-2 imida - i-bitrate enzima, uthungelwano, akukho sihloko esicocekileyo - kunye nokungaqhelekanga kweendawo ezimbini zokukhupha ifomati enye.

Ingaba i-audio enezithotho ezininzi izakuhlala iphila ukuguqulwa kwe-MPG ukuya kwi-MP4?

Ewe - yonke i-audio track kwi MPG (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi MP4 xa isiqulathi seefayili esithe nkqo sixhasa i-audio ejikelezayo-eninzi. I-MKV ne-MOV ziphatha ii-audio tracks ezingaqhelekanga; i-MP4 ixhasa ezininzi kodwa abanye abadlali behardware babona kuphela i-track 1; i-WebM icapisiwe kwi-Opus / Vorbis track enye. I-MP4 yi-ISO/IEC 14496-14, imiselwe ngo-2001 kwaye ivela kwibhokisi yobeko lwe-QuickTime efanayo ne-MOV esetyenziswa.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula MPG ukuya ku MP4?

Izihloko eziphantsi ezicocekileyo (iingoma ezikhethiweyo) zihlala zikhona xa MP4 zingazithabatha: i-MKV igcina i-SRT, i-ASS, i-SSA, i-PGS, i-VobSub ngokusemthethweni; i-MP4 igcina kuphela i-mov_text (ifomati ethe tyaba). Ukutshintsha i-MKV enezihloko eziphantsi ze-ASS zibe yi-MP4 kuya kuzisa iindidi eziphantsi kwi-mov_text okanye ukutshabalalisa. Iisihloko ezinzima (eziqhutywe kwividiyo) zithatha ngaphezulu nokuba kunjalo.

Ingaba MPG ukuya ku MP4 igcina abaphawuli besahluko / ulawulo olufana ne-DVD?

I-metadata yesichazi-magama idlulisa phakathi kwe-MPG ne-MP4 xa zombini iziqulatho zixhasa isichazi-magama se-atomic (MKV, MP4, MOV). I-WebM igcina isichazi-magama kwi-Matroska-compatible block, ngoko ke i-MKV <-> i-WebM isichazi-magama sihamba ngokucocekileyo. I-AVI ayinasichazi-magama esichaziweyo, ngoko ke ukuguqula i-AVI ibe yi-MP4 yenza ifayili engachazi-magama ngaphandle kokuba udibanisa abaphawuli ngesandla.

Yintoni malunga neziqulathi zeefayili ze-MKV (ifonti, umzobo wesiqulathi seefayili) xa usiya kwi MPG ukuya kwi MP4?

MKV yindawo yokugcina i-mainstream kuphela egcina iifayile ezifakiwe ngokuzithandela (ifonti ze-TTF ze-ASS subs, ubugcisa be-JPG cover, i-fan-translated PDF inserts). Ukusuka kwi MPG ukuya kwi MP4 ushiya ezi fayili zifakiwe xa i-MP4 ayiyiyo i-MKV — i-elementary streams iguqula, kodwa umthwalo odityanisiweyo uhlala kummthombo. Gcina i-MPG njengengxelo yangaphambili ukuba uxhomekeke kwifonti ezifakelweyo.

Yeyiphi i-codec esetyenziswa yi-MP4 kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne MP4 isiqulathi seefayili ngokukhuselekileyo: MKV imiselwe ku-H.265 (HEVC) ukufezekisa ukucinezela okungcono; MP4 imiselwe ku-H.264 ukufezekisa inkxaso yesixhobo esibanzi; WebM imiselwe ku-VP9; AVI isebenzisa i-MPEG-4 ASP (DivX/Xvid lineage). Nciphisa nge-codec ephambili esuka ezantsi — AV1 ifumaneka kwi-MKV / WebM apho ufuna khona ukucinezela okuphezulu kwaye ungalindela ukungenisa ikhowudi.

I-HDR (HDR10, Dolby Vision) ihlala njani MPG ukuya ku MP4?

I-HDR metadata ehlala njalo (i-HDR10 ibonisa amaxabiso aphezulu, umphakamo ophezulu wokukhanya kwezinto eziquletheyo) ihamba phantsi ukuya kwi-MP4 xa zombini iziqulatho kunye ne-codec ekhethiweyo ixhasa (HEVC, AV1 kwi-MKV / MP4). I-Dolby Vision inamandla ngakumbi — i-DV profile 5 / 7 / 8.1 kwi-MPG ihlala kuphela kwi-MKV ene-HEVC; ukutshintsha kwi-MP4 isiqulatho esingathwali umbala we-DV ihamba phantsi ukuya kwi-HDR10.
