MPG ukuba MPEG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho ye-MPG 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-MPEG output ifumana i-codec exhasa isiqulathi seefayili: H.264 ye-MP4, MOV ne-MKV, VP9 ye-WebM. Okuqulethwe yi-MPEG-1 okanye i-MPEG-2 ividiyo ene-MP2 umsindo; ukudibanisa nokwakhiwa kwe-GOP kufana ne-.mpeg ifayili. Ividiyo yi-MPEG-1 okanye i-MPEG-2 ene MP2 okanye AC-3 yesandi, ephindaphindwa kwi-stream eyenziwe ukuba ikhowudiwe yi-hardware esebenza ngokusisigxina.

Ingaba i MPG ingaguqulwa ibe yi MPEG ngaphandle kokubuyisela umbhalo ofihlakeleyo wevidiyo?

Hayi, hayi kule phepha. MPG ne MPEG zisebenzisa ukwakhiwa okuphantsi okufanayo, kodwa umguquli uphinde ukhowudi ividiyo kule par ngaphandle kokukopa umsinga, ngoko kuthatha ixesha elide kunesiqulathi sotshintsho kwaye umfanekiso ucinezelwe kwakhona. Khetha Ubunjani obuphezulu phantsi koBunjani ukugcina inkcukacha ezininzi. I-MPG ifana nenkqubo ye-MPEG ejikelezayo njenge-.mpeg — uluhlu lweeleta ezintathu luyi-DOS-era truncation, hayi ifomati eyahlukileyo. I-MPEG apha ithetha i-MPEG-1 okanye i-MPEG-2 inkqubo yokuhamba, ifomati emiselweyo ye Video CD kwaye emva koko ye DVD kunye nokusasazwa kweTV.

Ingaba kukho incopho eguqula phakathi kwefomati ezimbini ezidala njenge MPG ne MPEG?

Ukuba nje inxalenye ekhethekileyo yezixhobo ifuna injongo. Iifomati zombini zivela kwixesha elifanayo elingaphambili le-H.264, ngoko akukho kuguqulelo luthenga ukusetyenziswa kakuhle, umgangatho okanye uqinisekiso lwexesha elizayo - luthenga ukulungelelaniswa nesixhobo esithile. Ukuba injongo kukugcina imifanekiso esetyenziswa ixesha elide, guqula kwicontainer yangoku endaweni ye-sideways. MPG ifumana yonke i MPEG-2 imida - i-bitrate enzima, uthungelwano, akukho sihloko esicocekileyo - kunye nokungaqhelekanga kweendawo ezimbini zokukhupha ifomati enye. I-MPEG-2 ifuna iindidi ezine ukuya kwezisithandathu ze-bitrate ye-H.264 yomfanekiso ofanayo, kwaye imixholo yayo ihlala idityaniswa, ebonakala icocekile kwi-displays yakudala.

Yeyiphi i-codec yevidiyo esetyenziswa yi-MPEG?

Oku kuxhomekeke kwi-MPEG 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 kuqhubeka uguquka ukusuka kwi MPG ukuya kwi MPEG?

Ewe, umculo ophambili wesandi udlula, uphinde ukhowudiwe kwi-codec i-MPEG 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 yokuqala xa ndiguqula i-MPG ibe yi-MPEG?

Ewe. Umyinge we-frame igcinwa ngaphandle kokuba uyitshintshe: i-24 fps MPG ihlala i-24 fps kwi-MPEG. Ummiselo we-Frame Rate unokuguqula ibe yi-60, 30 okanye i-24 fps. Itshintsha kuphela umyinge; ayitshintshi i-interlace yevidiyo okanye isuse i-3:2 pulldown.

Ubungakanani befayili butshintsha njani ukusuka kwi MPG ukuya kwi MPEG?

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-MPG ene-bitrate ephezulu 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 kwi-quality efana nayo kodwa idlala kwizixhobo ezincinci.

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

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 edala. 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. Iinkqubo ze MPEG ziguqulwa kolunye ulwimi zisebenzisa wonke umdlali we DVD, ibhokisi ebekwe phezulu kunye nomjelo wosasazo owenziwe ngaphambili, kwaye zithobela iimpazamo zebithi ngokulula.

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

Akukho xesha elimiselweyo: 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 uguqulele 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 MPG ukuya kwi MPEG?

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 MPG ingabonakalisa i-washed out.

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

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

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

Ayikho kwinyathelo elifanayo. Sebenzisa /trim-video/ okanye /video-cutter/ ukucima i-MPG kuqala, okanye /rotate-video/ ukujika, emva koko qhuba i-MPG ukuya kwi-MPEG uguqulelo. Ukucima kuqala kukhawulezayo kune-re-encoding ye-MPG yonke ukushiya imifanekiso engasebenziswanga.

MPG

IMPG lulwandiso lwefayile yeMPEG-1 okanye MPEG-2 iifayile zevidiyo. Isetyenziswa ngokuqhelekileyo ukudlala ividiyo kunye nokusasazwa.

MPEG

I-MPEG (iQela leeNgcali zeMifanekiso eshukumayo) lusapho lwevidiyo kunye neefomati zokucinezela iaudio ezisetyenziswa ngokubanzi ukugcinwa kwevidiyo kunye nokudlala kwakhona.
