WebM ukuba WebP Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-WebM ividiyo ibe yi-WebP ephilayo?

Layisha phezulu i WebM kwaye umguquli uthathe iisampulu ze-frames (okungagqibekanga 15 fps), uzifumanise kwi WebP ephilayo, kwaye usebenzise ubungakanani bengqokelela yezixhobo obulungelelanisiweyo kwi WebP ifomati (i-GIF ifumana i-256-color palette elungelelanisiweyo; i-WebP ephilayo ixhasa umbala opheleleyo we-24-bit). I-WebM yinxalenye encinci eqinileyo ye-Matroska epapashwe yiGoogle ngo-2010 ekhethekileyo ukunika i-HTML5 ividiyo isiqulathi seefayili esingenazo iirhafu. I-WebP yifomati yomfanekiso yeGoogle ka-2010, eyenziwe kwi-VP8 keyframe encoder kwaye imiselwe ukubuyisela i-JPG, i-PNG ne-GIF ngaxeshanye.

Ndikhetha njani imizuzwana emininzi ye WebM ukuze ndidwelise?

Vula kumdlali, fumana ixesha kwaye uqaphele ikhowudi yexesha, kuba WebM ayisoloko ithatha uphawu lwesithuba sokuhamba. Ncamathisela kulo mhlaba wexesha lokuqalisa, yongeza ixesha elithathayo, kwaye umguquli ukhangela kulo mfanekiso kwaye ukhupha ikhowudi kuphela kwinqanaba olumkileyo. Ukukhangela kulungile kwisakhelo, kodwa kunokuba kulungileyo kuphela njengenani elinikezelwa - khangela ngokuchasene nokujonga phambi koshicilelo phambi kokufaka ikhonkco elide. I-WebM ilungile naphi na ngaphandle kwebrowser - abahleli bevidiyo, ii-galeri zefowuni ezisemthethweni kunye neSmart TVs ziyihoyi kakhulu.

Ingaba i-codec ngaphakathi kwe WebM itshintsha i-WebP endiyifumanayo?

Ayiyiyo imifanekiso, kuphela ulinde. A WebM yi Matroska- usapho lwesiqulathi seefayili, kwaye elo sapho ligcina isiqulathi seefayili kunye ne codec ngokudibeneyo - into efile igcina ngokuqinisekileyo yagqibwa xa yabhalwa kwaye ayibhekiswa kuyo ngesiqendu. Umguquli uguqula uguqulo oluthile kwifomathi eyenziweyo kuqala, kwaye ezo fayile zifana nokuba yeyiphi ifomathi eyenziweyo. Ukuguqula uguqulo luthile kubiza kakhulu: i-codecs ezitsha, ezisebenzayo zithatha ixesha elide lokususa ibhokisi kunezo zakudala, ngoko ii WebM iifayile ezimbini zobude obufanayo zingathatha ixesha elihlukileyo lokufikelela kwi-WebP efanayo. I-WebM imiselwe ukuba incinci: i-VP8 okanye i-VP9 ividiyo (i-AV1 ngoku isasazeka) ene-Vorbis okanye i-Opus isandi, akukho nto enye.

Le WebM yavela kwiphepha le-web - inokutshintshwa ibe yi WebP?

Ewe, xa ufumana ifayile. I WebM yiyo esetyenziswa yi web kwividiyo ekwilayini ecacileyo kuba ibrowser idlala ngaphandle koplugin, ngoko iclip edlala kwi tab ihlala i WebM eqhelekileyo egcina kwaye ikhupha apha njenge nayiphi na enye ifayile. Ukungafaniyo kumdlalo osasazayo onika iziqendu ezifutshane ezilinganisayo endaweni yefayile enye - ezi kufuneka ziphinde zidityaniswe phambi kokuba nantoni na iguqulwe. Iimvume ziyinto enye ekufuneka iqinisekiswe: ukukwazi ukulayisha ezantsi ividiyo ayifani nokuba uvunyelwe ukushicilela kwakhona udweliso oluyenziweyo. 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 iifayili ezikwi-WebP ephilayo kufuneka zibe nelahleko okanye zingalahleki?

Ilahlekile, nantoni na eyaqala njengevidiyo. I-WebP ephefumlelweyo ingakhowudisa iframes zayo ngayiphi na indlela: indlela engalahlekiyo igcina yonke i-pixel kwaye ilungele imifanekiso ethe tyaba kunye nombhalo wekhusi, ngelixa indlela engalahlekiyo isebenzisa umbono osekelwe kwibloki wohlobo lwe-codec yevidiyo esebenzisayo kwaye ilungele imifanekiso ebonakalayo. Iiframe zekhamera zigcwele i-grain elungileyo kunye ne-gradients apho uxinzelelo olungalahlekiyo lufumananga umzobo, ngoko ke ubugcisa olungalahlekiyo lweclip erekhodiweyo luya kusebenza amaxesha amaninzi ubungakanani be-lossy one ebonakala ngathi ifana. Yishiye ilahlekile ngaphandle kokuba umthombo wawungurekhodo lwekhusi lombhalo ocacileyo. I-WebP ihlala ikwinqanaba lesithathu ngaphandle komkhangeli zincwadi — ushicilelo lokuhamba komsebenzi, i-Office edala i-Office edala i-Office kunye nezinye ii-galeri zefowuni aziyi kuxhaswa.

Ingaba i WebM iclip yam kufuneka ibe futshane kangakanani na ukuze i WebP isebenze?

I-animated WebP isebenza kakuhle kwii-clip ezingaphantsi kwee-seconds ezili-10. Kungaphezulu kwee-balloons zefayili (i-GIF ibalulekile kwi-frame nganye engacinezelwanga). Kwi-animations ezide injongo i-animated WebP okanye APNG, zombini zisebenzisa i-video-codec-grade compression ne-scale kakhulu.

Ubungakanani befayili ekufuneka ndililindele kuphi kwi-5-imizuzu WebM → WebP?

I-GIF ephefumlelweyo: 2 ukuya 8 MB kwi-480p kuxhomekeke kunzima kokuhamba. I-WebP ephefumlelweyo: 200 KB ukuya kwi-1 MB kwi-resolution / umgangatho ofanayo. I-WebP ephefumlelweyo i-5 ukuya kwi-10x ingcono kune-GIF kumgangatho ofanayo wokubona. I-WebP inikezela zombini iimeko ezilahlekileyo nezingalahlekileyo, ngokubonisa ngokucacileyo kwe-alpha noopopayi abafumanekayo kumnye.

Ingaba uopopayi we WebP uya kuba nefomati efanayo ne WebM?

Ngokungagqibekanga siyikhupha i-sample ukuya kwi-15fps ye-GIF ejikelezayo (isebenza ngokubonakalayo ngaphezulu kwe-25fps) kunye ne-24fps ye-WebP / APNG ejikelezayo (ephatha i-rate ephezulu ngokucocekileyo). Nciphisa ngokugqithiseleyo nge-frame-rate option ukuba umbonisi wakho uxhasa i-source rate.

Ingaba uopopayi WebP uyadlala isandi ukusuka kwi WebM?

Hayi — iifomati WebP eziphilayo (i-GIF, i-WebP, i-APNG) azigcinwanga isandi. Ukuba ufuna isandi, misela isiqulathi sevidiyo (i-MP4, i-WebM) endaweni yefomati yomfanekiso ophilayo.

Ndingayenza i WebP yoopopayi ijikeleze ngokusisigxina?

Ewe - ukhetho lokubala iilophu lulawula ukuba i WebP iilophu liphela (elimiselweyo), idlala i-N amaxesha, okanye idlala ngokuchanekileyo kabini. Ubalo lwelophu lugcinwa kwi WebP i-metadata yesiqulathi seefayili kwaye luhlolwe ngazo zonke izibonisi zexesha elidlulileyo.

Kutheni le nto i WebP yam ibonakala ingqukuva xa kuthelekiswa nomthombo WebM?

Izizathu ezimbini eziqhelekileyo. Eyona, i-frame-rate downsampling: 15 fps WebP ukusuka kwi-60 fps WebM ikhupha i-75% ye-frames; ilungisa nge-frame-rate slider. Eyona, i-palette quantification: i-GIF imiselwe kwimibala emi-256 kunye ne-gradient-heavy WebM dithers ebonakalayo. Tshintsha kwi-WebP ejikelezayo yobuxoki bombala opheleleyo.

Ndingayicima okanye ndiyiguqule ubungakanani be WebM phambi kokuba ndiyenze i WebP?

Ewe - ukhetho lokuguqula ubungakanani luyikhupha i-WebM ezantsi phambi kokukhupha isakhelo, oluyikhupha ngokugqithisileyo ubungakanani befayili ye-WebP. I-480p WebP ukusuka kwi-4K WebM incinci nge-16x kune-4K WebP. Sebenzisa /video-cutter/ ukutywina kwinyathelo elahlukileyo.
