MOV ukuba WebP Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu i MOV 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). MOV yi Apple QuickTime isiqulathi seefayili, ethunyelwe ngo-1991 kwaye ihlala ifomati iPhone, iPad okanye Final Cut Pro umgca wexesha ubhala ngokumiselweyo. I-WebP yifomati yomfanekiso yeGoogle ka-2010, eyenziwe kwi-VP8 keyframe encoder kwaye imiselwe ukubuyisela i-JPG, i-PNG ne-GIF ngaxeshanye.

Ndingasebenzisa iimpawu zesiqulathi seefayili kwi MOV ukukhetha into ekufuneka isebenze?

Ewe, kwaye yindlela ekhawulezayo yokufumana ixesha ofuna. I MOV igcina iziqendu eziphawulweyo kwisiqulathi seefayili njengeziphawuli zexesha ezibizwa ngokuba zii-timestamps, ngoko uluhlu lunokufundwa ngokuthe ngqo kwifayile kunye ne-in-point ecoliweyo kwindawo yexesha lokuqala endaweni yokuqhutywa ngesandla. Nceda unikezele ixesha elifutshane kunye nokuphela kwexesha elifutshane lidecoded, oko kukuthi, ubude becala le MOV yenza akukho tshintsho kwixesha elide lomsebenzi othathayo. MOV yifomati ababhali abaqeqeshiweyo abacelayo, kuba ihlala iphindaphinda iinqwelo-moya ezijikelezayo nge Final Cut Pro, Premiere ne DaVinci Resolve ngaphandle kokungasebenzi kohlobo.

Ingaba kubaluleke na ukuba i MOV ivela kwifowuni okanye kwikhamera?

I-MOV yifayili ye-ISO esekelwe kwi-media, kwaye eli sapho lirekhoda ujikelezo njengeflegi kwisiqulathi seefayili kunokuba lijikeleze ii-pixels - oko kukuthi, iclip ethathwe ngokuthe nkqo kwifowuni ingabonakaliyo kwi-player enye kwaye ihlale kwicala lenye. Umfanekiso ophilayo ukhiwa kwi-pixels ezifihliweyo, ngoko ke i-flegi kufuneka ihlolwe phambi kokuba i-frame yokuqala ibhalwe; ukuba ukujonga ngaphambili kubuyela umva, ujikeleze umthombo uguqule kwakhona. Zonke izinto ezingaphezulu malunga nekhamera okanye umhleli woshicilelo ziyimeko elula: umkhondo wevidiyo omnye, umsinga oqinileyo we-frames. I-MOV ihlala ihambisa i-H.264 okanye i-HEVC yokuhambisa, okanye i-ProRes xa i-master edityaniswe, kunye ne-AAC okanye i-PCM engenakucothayo.

Kutheni i-browser yam ingavuli MOV endifuna ukuwudwelisa?

Kuba MOV ayiyiyo ibhokisi yomkhangeli zincwadi abamele baxhase, kwaye isakhiwo esilawulayo sitshintsha kunokuba siqinisekiswe. Ayitshintshanga nto malunga noguqulelo - ifayile ikhowudiwe kwicala lomncedisi, ngoko ke ibhokisi yomkhangeli zincwadi ayivumeli ukutshintsha ngokuchanekileyo njengenye iyamkela, kwaye akukho bhokisi yekhowudi yobulali ifunekayo ukuyisebenzisa apha. Kubalulekile ukwazi indlela yorhwebo oluqhuba ngayo, nangona: i WebP eyenziweyo ebuyayo yifomati yonke ibhokisi yomkhangeli zincwadi ibonisa, ngoko ke le ihambisa i clip ukusuka kwinto eweb ayizukuncama into eyenzayo. Iifayile ze-MOV zikhulu, kwaye ngaphandle kwenkqubo yokudlala ye-Apple ecosystem inkxaso ingaphezulu kwe-MP4 — i-Android edala i-Android edala kwaye ezinye iiTV eziSmart ziya kuzinyamezela.

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 MOV 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 MOV → 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 MOV?

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 MOV?

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 MOV?

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

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

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