WMV ukuba AVI Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Xa i WMV ne AVI 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 AVI isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB WMV kwi AVI ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho.

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

Ewe - yonke i-audio track kwi WMV (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi AVI 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.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula WMV ukuya ku AVI?

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

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

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

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

Yeyiphi i-codec esetyenziswa yi-AVI kwimveliso ngokumiselweyo?

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

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

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

MKV ne WebM zirekhoda i-frame nganye yexesha elipheleleyo kunye nokuphatha i-VFR ngokusemthethweni, ngoko ke i-WMV VFR ihlala kwi-AVI 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 WMV ukuya kwi-24 / 30 / 60 fps AVI kwiinjongo ezinomngcipheko.

Kutheni i-AVI ifayili yam incinci / ikhulu kune-WMV emva kokuguqulwa?

I-remux ye-codec efanayo ivelisa ubungakanani obufanayo (i-container overhead ihluka nge-0.1-2%). Utshintsho lwe-codec lunokutshintsha ubungakanani nge-50% okanye ngaphezulu: H.264 ukuya kwi-H.265 ngokuqhelekileyo iqulethe ifayili kwinqanaba elifanayo lomgangatho wokubona; H.264 ukuya kwi-AV1 iqulethe kwakhona kwi-preset ecocekileyo. Ukusuka kwi-bitrate ephezulu WMV (Blu-ray rip) ukuya kwi-bitrate ephantsi AVI (ukukhuphela kwi-web) yisizathu esiqhelekileyo sokuhla okuphezulu.

Ingaba i-WMV ukuya kwi-AVI iguqula i-4K / 8K / 60fps iqulethe?

Ewe ukuya kwi-8K (7680x4320) kwi-Premium. Umphakamo okhululekileyo uphatha i-4K (3840x2160) ukuya kwi-1 GB yefayili. I-pure remuxes (i-codec efanayo edlulayo) ye WMV enkulu kwi-AVI imiselwe yi-disk I/O, hayi i-CPU — i-30 GB WMV iqhelekileyo i-remuxes kwi-AVI ngaphantsi komzuzu ngaphandle kokuxhomekeka kwi-resolution. I-re-encodes i-scale nge-pixel count.

Ingaba i-WMV yam ifayile ifihlakeleyo ngexesha lokuguqulwa kwe-AVI?

Ewe — iifayile ezilayishwe phezulu WMV ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu yokuphela. Asizukuzijonga, sizigcine, sizigcine, okanye sizonwabele iziqulatho. Bona /privacy/ kwifestile yokugcina i-data. Inkqubo yokuguqula iqhuba kwihardware esilawulayo ukusuka ekupheleni ukuya ekupheleni; akukho qela lesithathu le-APIs lifumana ifayili yakho.

Ndingazicima, ndizikhuphe, okanye ndizifake kwi WMV iifayile ngexesha lokuguqula i AVI?

Not in the same job — keep conversion focused on container / codec. Use /trim/ to clip the WMV first, then queue the WMV -> AVI step. For joining several clips into one AVI, the /merge/ tool stitches them on a per-codec basis (it remuxes when the inputs share a codec, re-encodes otherwise) and emits a single AVI file at the end.

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