AVI ukuba WebM Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Xa i AVI ne WebM 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 WebM isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB AVI kwi WebM ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. Iifayili ze-AVI zingaphambili kunee-codecs ezitsha: lindele i-MPEG-4 Inxalenye ye-2 (DivX/Xvid), i-Motion JPEG okanye iifayili ezingenakucothayo ezingenakucothayo kunokuba i-H.264. I-WebM imiselwe ukuba incinci: i-VP8 okanye i-VP9 ividiyo (i-AV1 ngoku isasazeka) ene-Vorbis okanye i-Opus isandi, akukho nto enye.

I-AVI yevidiyo yam ibonisa imigca ye-comb kwi-movement - iya kuthatha into kwi-WebM?

Iya kwenza ukuba awuyi-deinterlace, kwaye AVI 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 WebM. AVI yiMicrosoft's Audio Video Interleave, enikezelwe ngowe-1992 phezulu kwe RIFF chunk format - enye yezinto ezidala ezigcinwe zihlala zijikeleza.

I-AVI yam yokurekhoda ihlukaniswe ibe ziinxalenye ezilinganisayo - ngaba i-WebM inemida efanayo?

Hayi, kwaye le yenye yezona zizathu zilungileyo zokushenxisa. I AVI 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. WebM ayinalo umda ofanayo, ngoko ke iinxalenye zingadityaniswa kwakhona kwifayile enye eqhubekayo. I-AVI ayinakuxhaswa kwe-codecs ekutsha, i-frame rate etshintshayo, izihloko ezimfutshane ezicocekileyo okanye iifayile ezingaphezulu kwe-4 GB ngaphandle kwe-hacks, kwaye i-chunk nganye i-overhead ikhupha ifayili.

Ndingazifaka njani izihloko ezingaphantsi ezikhethiweyo xa ifayili ikwi WebM?

Ewe. AVI ayinayo i-soft-subtitle track esetyenziswayo, ngoko ke i-subtitles ye-AVI iqulethe into ekufuneka ikhutshwe kumfanekiso okanye ithunyelwe njengefayili ye-sidecar eyahlukileyo. WebM ithatha i-subtitles njenge-stream yabo ekhethiweyo, ngoko ke emva kokuguqula ungadibanisa i-SRT track imboniso ingatshintshwa, itshintshwe okanye iphinde iguqulwe.

I AVI yam inezinto ezininzi ezidlala umculo - ngaba zonke ziya kuhlala zikhona kwi WebM?

Ayithembekanga. AVI igcina imijelo emininzi yesandi njengemizila yohlobo lokuqala, kodwa WebM 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. AVI ilula kakhulu, oko kukuthi kutheni i-camcorders yakudala, ikhadi lokufota, iDVD isixhobo sokutywina kunye neWindows-exesha lesoftware zonke zihlala zikhupha. I-WebM ilungile naphi na ngaphandle kwebrowser - abahleli bevidiyo, ii-galeri zefowuni eziqhelekileyo kunye neSmart TVs ziyihoyi kakhulu.

Ingaba i WebM iyadlala kwisikhangeli xa i AVI ayiyidlala?

Ewe, kwaye oko kuqhelekileyo isizathu esipheleleyo sokuguqula. A AVI efakwe kwiphepha le web okanye ibonisa umdlali olahlwayo okanye iforce ulwaleko, kuba ibrowser ayithuthinga i decoder kuyo. WebM idlala kwilayini esuka kwi HTML5 eqhelekileyo isixhobo sevidiyo ngaphandle koplugin kwaye akukho sicelo sengaphandle. I-WebM idlala ngokusemthethweni kwi-browser nganye ekhoyo ngoku ngaphandle kokufaka, ngaphandle kwelayisensi yemali, ngaphandle kokubonisa ipateni, eyenza ukuba imiselwe kwividiyo efakwe kwi-web.

Ingaba kufanelekile ukutshintsha i AVI yoshicilelo oludala ukuya kwi WebM?

Ukuba ufuna ukugcina into, ewe. AVI ibhekisa kuhlobo oludlulileyo lwezixhobo zevidiyo kwaye isoftware efunda i-video ihlala iphela kwifowuni, iziphene kunye nenkqubo yokusebenza. Ukushenxisa imifanekiso kwi WebM ngoku, ngelixa i-decoder ecocekileyo ikhona, kuhlukile phakathi kovimba onokuthi uvule kwiminyaka elishumi kunye noyena awukwazi.

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

Ewe - yonke i-audio track kwi AVI (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi WebM 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. I-WebM yinxalenye encinci eqinileyo ye-Matroska epapashwe yiGoogle ngo-2010 ekhethekileyo ukunika i-HTML5 ividiyo isiqulathi seefayili esingenazo iirhafu.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula AVI ukuya ku WebM?

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

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

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

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

Yeyiphi i-codec esetyenziswa yi-WebM kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne WebM 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.
