WMV ukuba FLV Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Xa i WMV ne FLV 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 FLV isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB WMV kwi FLV ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. I-WMV ihambisa i-Microsoft VC-1 okanye i-WMV3 yevidiyo ngesandi se-WMA — ii-codecs azikho nto ngaphandle kweWindows ikhupha ikhowudi ngokusemthethweni. I-FLV ihlala igcina i-Sorrenson Spark okanye i-H.264 video ene-MP3 okanye i-AAC yesandi, ejikelezwe kwifomati yokuhamba eyenziweyo yokuhambisa i-RTMP.

I-WMV yevidiyo yam ibonisa imigca ye-comb kwi-movement - iya kuthatha into kwi-FLV?

Iya kwenza ukuba awuyi-deinterlace, kwaye WMV 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 ezipheleleyo eziqhubekayo phambi kokubhala i FLV. WMV yiWindows Media Video, iMicrosoft's ASF-based format ukusuka kwixesha leWindows XP.

Yintoni eyenza i-5.1 surround audio xa iguqula WMV ukuya FLV?

I-stereo iqhutywa phantsi, kuba FLV ayinayo indlela ethembekileyo ye-multichannel. Ukujika ezantsi kusetyenziswa i-ITU eqhelekileyo esebenza ngokufanayo ukuze unxibelelwano kwisiqhagamshelanisi esiphakathi sihlale siqondakalayo kwaye i-circumstances ifike kwinqanaba eliphantsi kunokuba iphele. Nantoni na exhomekeke kukubeka isiqhagamshelanisi esikhethekileyo siphelile emva koko. Akukho mkhangeli zincwadi, ifowuni okanye iTV iya kudlala i-FLV - nantoni na esele ikwi-container kufuneka ishenxiswe ngaphandle ukuze ihlale ibonakale.

Ingaba kukho incopho eguqula phakathi kwefomati ezimbini ezidala njenge WMV ne FLV?

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. 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.

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

Ewe - yonke i-audio track kwi WMV (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi FLV 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. FLV yindawo yokugcina i-Flash Video ehambisa yonke i-web video ukusuka ngo-2003 de i-Flash ivale ekupheleni konyaka ka-2020.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula WMV ukuya ku FLV?

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

I-metadata yesichazi-magama idlulisa phakathi kwe-WMV ne-FLV 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-FLV 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 FLV?

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 FLV ushiya ezi fayili zifakiwe xa i-FLV 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-FLV kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne FLV 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-FLV's ephantsi ngepakethi nganye i-overhead iyenze igqibelele kwi-streaming ngaphezulu konxibelelwano olungathembekiyo lwexesha lakhe, kwaye ii-archives ezinkulu zayo zihlala zikhona.

I-HDR (HDR10, Dolby Vision) ihlala njani WMV ukuya ku FLV?

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

Ingaba i-WMV ukuya kwi-FLV 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-FLV 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 FLV kwiinjongo ezinomngcipheko.

Kutheni i-FLV 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 FLV (ukukhuphela kwi-web) yisizathu esiqhelekileyo sokuhla okuphezulu.

WMV

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