MP4 ukuba MPG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-MP4 ibe yi-MPG ngaphandle kokulahleka komgangatho?

Layisha phezulu ifayili yakho ye-MP4 kwaye umisele Umgangatho kwiNtlonipho eNkulu kwizinto ezikhethwayo zokuguqula. Oku kuphinda kuqulethe ividiyo kwisicwangciso esiphezulu somgangatho (CRF 18 ye-H.264 ne-VP9 output), egcina inkcukacha ezininzi kwixabiso lefayili enkulu. Okumiselweyo, Okuthe nkqo, sebenzisa isicwangciso esiqhelekileyo. I-MPG output ifumana i-codec exhasa isiqulathi seefayili: H.264 ye-MP4, MOV ne-MKV, VP9 ye-WebM.

I-codec eyiphi esetyenziswa yi-MPG?

Oku kuxhomekeke kwi-MPG container. I-MP4, MOV ne-MKV output isebenzisa i-H.264, edlala kwifowuni yonke, umkhangeli zincwadi neTV. I-WebM output isebenzisa i-VP9. I-AVI, WMV ne-MPEG output isebenzisa ii-codecs ezidala ezo fomati zaphuhliswa kuzo.

Ingaba umculo wam wesandi uya kuhlala uphila MP4 ukuya ku MPG?

Ewe, umculo ophambili wesandi udlula, uphinde ukhowudiwe kwi-codec i-MPG idlala, umzekelo i-AAC kwi-MP4 ne-MOV okanye i-Opus kwi-WebM. Iindawo ezininzi zokuguqulela zigcina kuphela umculo omnye (onye oneendawo ezininzi), ngoko ke iilwimi ezitshintshiweyo kunye nolwazi olusisiseko lulahliwe. I-MP4 ukuya kwi-MOV, ne-AVI, WMV, MPEG, FLV, VOB okanye M4V ukuya kwi-MKV, gcina wonke umculo wesandi.

Ndingagcina i-framerate emiselweyo isuka kwi-MP4 ukuya kwi-MPG?

Ewe. Umyinge we-frame igcinwa ngaphandle kokuba uyitshintshe: i-24 fps MP4 ihlala i-24 fps kwi-MPG. Ucwangciso lwe-Frame Rate lunokutshintsha kwakhona ukuya kwi-60, 30 okanye 24 fps. Itshintsha kuphela umyinge; ayiyi-deinterlace ividiyo okanye isuse i-3:2 pulldown.

Yintoni ubungakanani befayili obuhlukileyo phakathi kwe MP4 ne MPG?

Oku kuxhomekeke ekubeni kwenzeka ntoni kwividiyo. I-MKV ukuya kwi-MP4 okanye i-MOV ngemimiselo emiselweyo ikopa umsinga wevidiyo ungatshintshwanga, ngoko ubungakanani buhlala bufutshane nomcebo. Ezinye iipere ziphinda ziyikhowudi: i-bitrate ephezulu MP4 ihlala iphuma incinci, ngelixa enye ekhoyo icinezelwe kakhulu ikhula. Ifayile encinci phantsi koBunjani inika imveliso encinci, kwaye i-H.265 kuMmiselo weCodec (MP4, MOV ne-MKV) ihlala incinci kune-H.264 kwimvelaphi efana nobunjani kodwa idlala kwizixhobo ezincinci.

Ingaba ifayili MPG iyadlala kwi-iPhone / Android / Smart TV?

MP4 kunye H.264 idlala kwi-smartphone, i-browser kunye ne-TV. MOV kunye ne-H.264 idlala kwi-Apple kunye ne-TV ezininzi kodwa hayi kwi-smartphone ye-Android. MKV ifuna i-app efana ne-VLC kwi-iOS, kwaye i-WebM ihlala ekhaya kwii-browser. Akukho sixhobo esimiselweyo kule phepha, ngoko khetha ifomati efanelekileyo yesixhobo sakho esixhasayo.

Ithatha ixesha elingakanani ukutshintsha ifayili ye-1-iyure MP4 ibe yi MPG?

Akukho xesha limiselweyo: lixhomekeke kubungakanani, ubungakanani obucacileyo kunye nohlobo lwenjongo. Uguqulelo luyasebenza kwiseva yethu ye-CPUs kunye nesoftware encoders; akukho GPU ekhawulezayo. MKV ukuya MP4 okanye MOV ngemimiselo emiselweyo ikopa umsinga wevidiyo kwaye ikhawuleza kakhulu. Ukuphinda ukhowudise kwi H.264 kuthatha ixesha elide, kwaye i WebM (VP9) yinjongo ekhawulezayo, iphinda ikhawuleze kakhulu kune H.264 kwiimvavanyo zethu.

Yintoni ubukhulu bomfanekiso oxhaswayo kwi MP4 ukuya kwi MPG?

Umguquli awunaso isiphelo somfanekiso ocacileyo; umda ubungakanani bokukhuphela obuvunyelweyo kwinkqubo yakho, kwaye umfanekiso ocacileyo uhlala njengonjalo ngaphandle kokuba ukhetha i-1080p, 720p okanye 480p. Akukho HDR uqhubekeko okanye umbala wokumaphu. Xa umsinga wevidiyo ukopiwe (MKV ukuya kwi-MP4 okanye MOV ngemimiselo emiselweyo), i-HDR10 idlula ngaphandle kokuxhathisa. Ukuphinda ukhowudi ukhupha i-HDR10 ulawulo lwemetadata, kunye noBunjani, Ubunjani okanye i-Frame Rate ucwangciso ezinye iipere zikhupha ividiyo kumbala we-8-bit, ngoko i-HDR MP4 ingabonakalisa i-washed out.

Ingaba i-MP4 yevidiyo yam ifihlakeleyo ngexesha lokuguqulwa kwe-MPG?

Ewe. Iifayile ezilayishwe phezulu ze MP4 ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga. Ukukhuphela kunye nokuguqulwa kwe MPG kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.

Ndingatywina okanye ndityhefe ngexesha lenyathelo MP4 ukuya ku-MPG?

Ayikumgangatho ofanayo — sebenzisa /video-trim/ okanye /video-cutter/ ukucima i MP4 kuqala, emva koko ufolo i MP4 -> MPG uguqulelo. Ukusika-ukuguqula-uguqulelo lukhawulezayo kune-ukubuyisela kwikhowudi ifayile yonke ukucima kuphela i-output.

Kutheni le nto ifayili MPG imnyama xa ithelekiswa nomboneleli MP4?

Imveliso iqhutywa ngokuqhelekileyo iqhutywa ngokuqinileyo kunendawo yokungena. Vula uguqulelo lwezinto ezikhethwayo, khetha Ubunjani Obuphezulu phantsi koBunjani, gcina Ugqibo kuBunjineli kwaye uguqule kwakhona. Akukho CRF okanye ilizwe le bitrate kule phepha; Ubunjani Obuphezulu yinkqubo egcina inkcukacha ezininzi.

Ingaba i-MP4 ukuya kwi-MPG iguqulela inkxaso yesihloko?

Kwiiperi ezithile. I-MP4 ukuya kwi-MOV igcina yonke i-track yombhalo ophantsi. I-AVI, i-WMV, i-MPEG, i-FLV, i-VOB ne-M4V ukuya kwi-MKV igcina yonke i-track yombhalo ophantsi: i-subtitles yombhalo ikhopiwe okanye iguqulwe kwi-SRT, kwaye i-subtitles esekelwe kwimifanekiso efana ne-DVD okanye i-Blu-ray ikhopiwe njengezi. I-MP4, i-MOV ne-WebM ukuya kwi-MKV igcina kuphela i-track yokuqala yombhalo ophantsi (njengo-ASS), ne-MP4 ukuya kwi-WebM igcina enye yokuqala njenge-WebVTT. Ezinye iiperi, kubandakanya i-MKV ukuya kwi-MP4 okanye i-MOV ne-WebM ukuya kwi-MP4, zikhupha i-tracks yombhalo ophantsi, kwaye umguquli awuzikhuphi kwimifanekiso. Ii-subtitles ezikhe zakhutshwa zihlala, kuba ziyinxalenye ye-frames yevidiyo.
