MP4 ukuba WMV Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Xa i MP4 ne WMV 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 WMV isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB MP4 kwi WMV ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. I-MP4 eninzi eluhlaza yi-H.264 yevidiyo enesandi se-AAC; isiqulathi sigcina ngokusemthethweni i-HEVC, i-AV1 ne-VP9. I-WMV ihambisa i-Microsoft VC-1 okanye i-WMV3 yevidiyo ngesandi se-WMA — ii-codecs azikho nto ngaphandle kweWindows ikhupha ikhowudi ngokusemthethweni.

Yintoni eyenza i-subtitle tracks kwifayili yam MP4?

Ayikwazi ukuhlala ikhethiwe, kuba WMV 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 WMV ukuze umdlali alayishe. Umguquli uthetha ukuba yintoni eyayenza kunokuba ikhuphe ngokucokisekileyo. WMV isebenza kakuhle iphele elahlekile: macOS, iOS, Android kunye ne-browser nganye kufuneka i-decoders yeqela lesithathu, kwaye ezinye iifayile ze-WMV zithwala i-DRM engatshintshi nantoni na.

Ndingayifaka njani ifayili kwiphepha le-web emva kokuguqula i-MP4 ibe yi-WMV?

Ayi ngqo. MP4 idlala umgca kwisixhobo sokukhangela yonke; WMV ayisebenzi, ngoko ke iphepha elidibanisa ibuyela umva kwikhonkco lokulayisha okanye isakhelo somdlali ongenanto. Ukuba ifayile icwangciswe kwiwebhusayithi, gcina i MP4 kwi-web kwaye uthathe i WMV njenge-archive okanye uhlela ikopi.

Ingaba i WMV iyaqhubeka idlala ngokulula kwifowuni okanye kwiTV?

Ingaba ayikwazi. MP4 ikhowudiwe yisilicon ekhethekileyo kwifowuni, iitablethi kunye neeTV, nto leyo eyenza ukuba idlala ngaphandle kokutyibilika kwebhetri. WMV ihlala ibuyela umva kwisoftware yokukhowudi kwihardware efanayo - ubunzima be CPU obuphezulu, isixhobo esishushu, kunye neeframes ezikhuphekayo kwi-4K material. Kwisixhobo esimiselweyo, MP4 yindawo ekhuselekileyo yokugcinwa ehlala kuyo.

Kutheni ndiyiguqula i MP4 ibe yifomati edala njenge WMV?

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 WMV kwaye akukho nto enye. Uguqulelo luya kugqiba inqanaba ezantsi kwimpumelelo, ithengiswe ukutshintshela ukusebenza kwisixhobo esingakho enye indlela yokukhetha. I-WMV icinezela kakuhle kubudala bayo kwaye ihlala i-format ye-PowerPoint, i-Windows edala i-screen recorders kunye neendawo zokugcina i-corporate media zilindele.

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

Ewe - yonke i-audio track kwi MP4 (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi WMV 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. WMV yiWindows Media Video, iMicrosoft's ASF-based format ukusuka kwixesha leWindows XP.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula MP4 ukuya ku WMV?

Izihloko eziphantsi ezicocekileyo (iingoma ezikhethiweyo) zihlala zikhona xa WMV 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 MP4 ukuya ku WMV igcina abaphawuli besahluko / ulawulo olufana ne-DVD?

I-metadata yesichazi-magama idlulisa phakathi kwe-MP4 ne-WMV 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-WMV yenza ifayili engachazi-magama ngaphandle kokuba udibanisa abaphawuli ngesandla.

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

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 MP4 ukuya kwi WMV ushiya ezi fayili zifakiwe xa i-WMV ayiyiyo i-MKV — i-elementary streams iguqula, kodwa umthwalo odityanisiweyo uhlala kummthombo. Gcina i-MP4 njengengxelo yangaphambili ukuba uxhomekeke kwifonti ezifakelweyo.

Yeyiphi i-codec esetyenziswa yi-WMV kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne WMV 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 MP4 ukuya ku WMV?

I-HDR metadata ehlala njalo (i-HDR10 ibonisa amaxabiso aphezulu, umphakamo ophezulu wokukhanya kwezinto eziquletheyo) ihamba phantsi ukuya kwi-WMV 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-MP4 ihlala kuphela kwi-MKV ene-HEVC; ukutshintsha kwi-WMV isiqulatho esingathwali umbala we-DV ihamba phantsi ukuya kwi-HDR10.

Ingaba i-MP4 ukuya kwi-WMV igcina i-framerate eguqukayo (VFR)?

MKV ne WebM zirekhoda i-frame nganye yexesha elipheleleyo kunye nokuphatha i-VFR ngokusemthethweni, ngoko ke i-MP4 VFR ihlala kwi-WMV yale fomati ngaphandle kokuphindaphinda. I-MP4 igcina i-timestamps ngokusemthethweni kodwa abanye abadlali bakholelwa ukuba i-CFR; umguquli ubonisa "ubunzima be-CFR" ukutshintsha okubuyisela i-VFR MP4 ukuya kwi-24 / 30 / 60 fps WMV kwiinjongo ezinomngcipheko.

MP4

Ifomathi yesikhongozeli seMP4 inokugcina ividiyo, iaudio, imibhalo engezantsi, kunye nemifanekiso kwifayile enye enoxinzelelo oluhle kakhulu.

WMV

I-WMV (iVidiyo yeWindows Media) yifomati yocinezelo yevidiyo ephuhliswe nguMicrosoft. Ngokuqhelekileyo isetyenziselwa ukusasaza kunye neenkonzo zevidiyo ze-intanethi.
