DivX ukuba MP4 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-DivX ibe yi-MP4 ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho ye DivX kwaye umguquli uqhube i-CRF-esekelwe kwi-encoding ephindayo ebhekisa kwi-visually-lossless MP4 imveliso (i-CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne MP4 isiqulathi-zifayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 yee-pipelines ezintsha. Imixholo ye-DivX yi-MPEG-4 Inxalenye ye-2 yevidiyo, eqhelekileyo ijikelezwe kwi-AVI, ene-MP3 okanye i-AC-3 yesandi ecaleni kwayo. I-MP4 eninzi eluhlaza yi-H.264 yevidiyo enesandi se-AAC; isiqulathi sigcina ngokusemthethweni i-HEVC, i-AV1 ne-VP9.

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

Iya kwenza ukuba awuyi-deinterlace, kwaye DivX 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 eziqhubekayo ezipheleleyo phambi kokubhala i MP4. I-DivX ibiza i-codec kunokuba i-container - i-MPEG-4 Inxalenye 2 yokusebenza eyenza ukukhupha i DVD kwi CD enye ekwaziyo malunga ne-1999.

I-DivX yam yokurekhoda ihlukaniswe ibe ziinxalenye ezilinganisayo - ngaba i-MP4 inemida efanayo?

Hayi, kwaye le yenye yezona zizathu zilungileyo zokushenxisa. I DivX isiqulathi siqulethe ifayile enye esebenzayo ethe tyaba eyenza ushicilelo olude okanye oluphezulu-bitrate luqhube ngokuthe ngqo, oko kukuthi, kutheni ushicilelo oludala lufika njengenxalenye1, ingxenye2, ingxenye3. MP4 ayinalo umda ofanayo, ngoko ke iinxalenye zingadityaniswa kwakhona kwifayile enye eqhubekayo. I-DivX ifuna ukuphindaphindwa kabini kwe-bitrate ye-H.264 yomgangatho ofanayo kwaye ayinayo indlela ye-HDR, 10-bit umbala okanye ugqibo ngaphezulu kwe-1080p.

Ndingazifaka njani izihloko ezingaphantsi ezikhethiweyo xa ifayili ikwi MP4?

Ewe. DivX ayinayo i-soft-subtitle track esetyenziswayo, ngoko ke i-subtitles ye DivX imixholo yakufuneka ikhutshwe kumfanekiso okanye ithunyelwe njengefayili ye-sidecar eyahlukileyo. MP4 ithatha i-subtitles njengemjelo yabo ekhethiweyo, ngoko ke emva kokuguqula ungadibanisa i-SRT track imboniso ingatshintshwa, itshintshwe okanye iphinde iguqulwe.

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

Ayithembekanga. DivX 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. Abadlali be-DVD abaqinisekisiweyo be-DivX bahlala beqhelekileyo, kwaye i-codec ihlala i-floor yokulungelelanisa udidi olupheleleyo lwezixhobo zekhompyutha ezisetiweyo. 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 DivX ayiyidlala?

Ewe, kwaye oko kuqhelekileyo isizathu esipheleleyo sokuguqula. A DivX 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 i MP4 iquka isiqulathi seefayili okanye i-codec, kwaye ngaba itshintsha into endiyifumanayo kwakhona?

Itshintsha into elindelekeyo kwifayile yemveliso. Icala elinye loguqulelo libiza ukukhowuda kunokuba ujikeleziso, ngoko oko kubuyela umva kukujikelezo lweebit ngaphakathi komgquba olungeleyo - ngokuqhelekileyo MP4 okanye MKV. Ulwandiso lubonisa umgquba; i codec yiyo eyaziyo ubungakanani befayile kwaye apho izakudlalwa khona.

Yeyiphi i-codec yevidiyo esetyenziswa yi-MP4?

Ixhomekeke kwi MP4 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-MP4 yi-ISO/IEC 14496-14, imiselwe ngo-2001 kwaye ivela kwibhokisi yobeko lwe-QuickTime efanayo ne-MOV esetyenziswa.

Ingaba umculo wam wesandi uya kuqhubeka uguquka ukusuka kwi DivX ukuya kwi MP4?

Ewe. Xa DivX ne MP4 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-MP4 ixhasa ntoni. I-audio enezithotho ezininzi (iingxelo, iilwimi ezitshintshiweyo) igcinwa.

Ndingagcina i-framerate yokuqala xa ndiguqula i-DivX ibe yi-MP4?

Ngokungagqibekanga ewe — i-24fps DivX ihlala i-24fps kwi-MP4; i-60fps DivX 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 DivX ukuya kwi MP4?

I-codec efanayo yokuphinda-phinda (DivX H.264 → MP4 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 MP4 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-MP4 codec / isiqulathi esikhuselekileyo senjongo yakho.

DivX

I-DivX yitekhnoloji yocinezelo lwevidiyo evumela ucinezelo lwevidiyo ekumgangatho ophezulu kunye neesayizi ezincinci zeefayile. Ihlala isetyenziselwa ukuhanjiswa kwevidiyo kwi-intanethi.
