FLV ukuba MKV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-FLV ibe yi-MKV ngaphandle kokubuyisela umbhalo ofihlakeleyo wevidiyo?

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

Ingaba i-audio enezithotho ezininzi izakuhlala iphila ukuguqulwa kwe-FLV ukuya kwi-MKV?

Ewe - yonke i-audio track kwi FLV (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi MKV 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 FLV ukuya ku MKV?

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

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

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

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

Yeyiphi i-codec esetyenziswa yi-MKV kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne MKV 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 FLV ukuya ku MKV?

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

Ingaba i-FLV ukuya kwi-MKV igcina i-framerate eguqukayo (VFR)?

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

Kutheni i-MKV ifayili yam incinci / ikhulu kune-FLV 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 FLV (Blu-ray rip) ukuya kwi-bitrate ephantsi MKV (ukukhuphela kwi-web) yisizathu esiqhelekileyo sokuhla okuphezulu.

Ingaba i-FLV ukuya kwi-MKV 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 FLV enkulu kwi-MKV imiselwe yi-disk I/O, hayi i-CPU — i-30 GB FLV iqhelekileyo i-remuxes kwi-MKV ngaphantsi komzuzu ngaphandle kokuxhomekeka kwi-resolution. I-re-encodes i-scale nge-pixel count.

Ingaba i-FLV yam ifayile ifihlakeleyo ngexesha lokuguqulwa kwe-MKV?

Ewe — iifayile ezilayishwe phezulu FLV 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 FLV iifayile ngexesha lokuguqula i MKV?

Not in the same job — keep conversion focused on container / codec. Use /trim/ to clip the FLV first, then queue the FLV -> MKV step. For joining several clips into one MKV, 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 MKV file at the end.

I-FLV (iVidiyo yeFlash) yifomati yesikhongozeli sevidiyo ephuhliswe nguAdobe. Isetyenziswa ngokuqhelekileyo ukusasazwa kwevidiyo kwi-intanethi kwaye ixhaswa yi-Adobe Flash Player.
