AVI ukuba Image Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-AVI video njenge-Image imifanekiso?

Layisha phezulu i AVI kwaye umguquli ubonisa umkhethi wesakhelo-sokukhupha: isakhelo ngasinye se-Nth, iisakhelo kwixesha elikhankanyiweyo, okanye isakhelo ngasinye kwisiqingatha seyure. Isakhelo ngasinye esikhethiweyo sikhowudiwe njengefayili ye-Image kwaye iseti epheleleyo ifakwe kwi-ZIP yovimba wokukhuphela. AVI yiMicrosoft's Audio Video Interleave, enikezelwe ngowe-1992 phezulu kwe RIFF chunk format - enye yezinto ezidala ezigcinwe zihlala zijikeleza. Umfanekiso apha yinjongo eqhelekileyo: umguquli ukhetha ifomati ye raster efanelekileyo yomthombo kunokuba uvumele enye kuwe.

Kutheni iifayili zam ezikhuphiweyo zineemigca ethe tyaba ezidlula kuzo?

Kuba umthombo udityaniswe. AVI imixholo evela kwixesha le-DVD nele-broadcast igcina iindawo ezimbini zomphakamo wesiqendu kwiframe nganye, ithathwe kwishumi elinesixhenxe sesekondi, kwaye i-still ethe tyaba ibonisa zombini ezidityaniswe njenge-combing nantoni na ehambayo. Yenza u-deinterlacing phambi kokukhupha kwaye i-still nganye ikhiwa ukusuka kwi-frame eqhubekayo eyenziwe kwakhona.

Ndingazifumana njani ii-Image iifayili ngaphandle kwesihloko esilandelayo?

Kuphela ukuba i AVI ayizange ibhalelwe, kuba i AVI ayinayo i-subtitle ekhethiweyo yokuqhuba ukucima. Nantoni na ebonisa i AVI kwisikrini sikwimifanekiso ngokwayo, ngoko ke yiyo yonke i Image ukukhupha ivelisa kwaye akukho mmiselo ususa emva koko. apho ifayile yesubtitle eyahlukileyo ikhona ecaleni kwevidiyo, ukhuphe ukusuka kummthombo ogcine isibini sihlukaniswe kwaye ii-frames ziphuma zicocekile. 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.

Ingaba i-Image ixhasa ukubonakaliswa ngokucacileyo?

Ifomati isebenza, kodwa umbhali akafuni i-alpha ukunika - ii-frames zevidiyo kunye neephepha ezibonisiweyo zicacile ngokupheleleyo, ngoko ke zonke ii-pixels zifika ziqinile. Isiqhagamshelanisi se-alpha sihlala sisetyenziswa emva koko: kuthetha ukuba ungacima into ephuma kwi-Image kamva ngaphandle kokuguqula i-format kwakhona. Ukukhetha isiphelo ngokuzenzekelayo kuthetha ukuba ufumana ifayile evula naphi na ngaphandle kokufuna ukuqonda malunga nee codecs kuqala.

Ingaba iifayili Image ziya kuba zikhulu kangakanani?

Ikhulu kunalo lonke ulindeleyo, kuba Image igcina i-pixel nganye ngokuchanekileyo kunokuba ilinganise. I-1080p ihlala iwela ngaphantsi kwe-2-5 MB kwaye i-4K ihlala ngaphantsi kwe-6-15 MB, ngoko ke ukuphuma okude kudibanisa ngokukhawuleza. Oku kurhwebo oluchanekileyo xa imifanekiso i feed iqhubekeka, kwaye okubi xa zihamba ngqo kwiphepha le-web. Iindawo ezivela kuzo iimifanekiso zimiselwe kwi-JPG, iindawo ezivela kuzo ezibonisa ngaphaya okanye imida eqinileyo zimiselwe kwi-PNG, kwaye iindawo ezivela kuzo iiphepha ezininzi zivelisa umfanekiso omnye kwiphepha ngalinye.

Ingaba ifayili enkulu kakhulu AVI iyakulayishwa ngokuphumelelayo?

Ii-akhawunti ezikhululekileyo zifikelela kwi-100 MB kwifayili nganye, AVI amacebo ahamba phezulu ngenxa yokuba ifomati ihambisa i-chunk nganye ebalulekileyo engaphezulu kwe-data yevidiyo. I-Premium iphakamisa i-cap ngokucacileyo. Ukuba ifayile ihlukaniswe ibe ziinxalenye ezilinganisayo ngenxa yefomati ye-ceiling, ulayishe nganye nganye kwaye zithathwe njengemisebenzi enye.

Uphi ubunzulu be-frame nganye ekhutshweyo Image ephumayo?

Ubungakanani obufanayo ne-AVI ividiyo — i-1080p AVI ivelisa i-1920×1080 Image ii-frames; i-4K AVI ivelisa i-3840×2160 Image ii-frames. Sebenzisa uncedo lokuguqula ubungakanani emva kokukhupha ukuba ufuna ii-thumbnails ezincinci okanye ubungakanani be-social-media-crops.

Ndingayikhupha isakhelo ngasinye esitsha kwi AVI njenge Image?

Ewe, kodwa uqaphele ngobalo lweefayili - i-30fps 1-minute AVI ivelisa i-1,800 Image iifayili. Sizipakisha kwi-ZIP ngokuzenzekelayo. Kwiiclip ezide, ukhetho "1 ngomzuzwana" (iifayili ezi-60) okanye iziqinisekiso zexesha elikhankanyiweyo zinika isiphumo esiphathwayo.

Ingaba imifanekiso ekhutshweyo Image iya kugcina umbala ophakamileyo AVI?

Lithini ubungakanani befayili yesakhelo esitshatweyo Image?

Ixhomekeke kwisisombululo kunye ne-Image codec. I-1080p PNG frame ihlala i-2 ukuya kwi-5 MB; i-1080p JPG kwi-quality-85 i-200 ukuya kwi-500 KB; i-4K PNG i-6 ukuya kwi-15 MB. Kwimeko egqithisileyo, ukukhupha i-PNG frame nganye ye-10-minute 1080p AVI kwenza ~50 GB ngokupheleleyo.

Sifaka `creation_time` indawo ebonisa umhla wokugqitywa kwesakhelo somthombo ukuze uphinde ulungelelanise i-bundle ngokulandelana kokuthatha.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka ku AVI ukuya ku Image?

Iifayile ze-AVI zinokuqulatha idatha yeaudio kunye nevidiyo, exhaswa kakhulu kodwa enobukhulu obukhulu beefayile.

Image

Iifayile zemifanekiso, ezifana neJPG, PNG, kunye neGIF, zigcina ulwazi olubonakalayo. Ezi fayile zingaqulatha iifoto, imizobo, okanye imifanekiso. Imifanekiso isetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanya uyilo lwewebhu, imidiya yedijithali, kunye nemifanekiso yamaxwebhu, ukuhambisa umxholo obonakalayo.
