AVI kuya Image Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani ifreyimu ngayinye kusuka ku AVI njenge Image izithombe?

Layisha phezulu ihele AVI futhi umguquli ubonisa isikhethi sefreyimu-sokukhipha: nganoma iyiphi ifreyimu ye-Nth, amafreyimu ezikhathini ezicacisiwe, noma ifreyimu eyodwa ngesekondi. Ifreyimu ngayinye ekhethiwe ikhishwa ku-AVI umsinga wevidiyo, ibhalwe njengehele Image elilodwa, futhi iqoqwe njenge-ZIP yokulayisha ngezansi. AVI Microsoft Audio Video Interleave, isungulwe ngo-1992 phezu RIFF chunk format - eyodwa yezinto eziphilayo ezidala kakhulu okwamanje e circulation. Isithombe lapha siyinjongo ejwayelekile: umguquli ukhetha ifomethi ye-raster efanele umsuka endaweni yokucindezela enye kuwe.

Kungani amafreyimu ami akhishwayo anemigqa ejikelezayo edlula kuwo?

Ngenxa yokuthi umsuka uxhunywe. AVI okuqukethwe kusuka ku-broadcast ne-DVD era igcina ama-fields amabili aphakathi nendawo aphezulu ngefremu ngayinye, athathwe ngengxenye engu-50 yesithupha, futhi i-still ekhishwa ngokuqondile ibonisa ukuthi zombili zixhunywe ndawonye njenge-combing nganoma yini ehambayo. Vumela u-deinterlacing ngaphambi kokukhipha futhi i-still ngayinye ikhiwa kusuka ku-frame eqhubekayo evuselelwe.

Ingabe ngithola ama-Image amafreyimu ngaphandle kwesihloko esingezansi?

Uma nje i AVI ayizange itshetshezwe, ngoba AVI ayinaso isingeniso esikhethiwe sohluzo esikhethiwe sokuvala. Noma yini eAVI ebonisa esigabeni isithombe, ngakho i Image ngayinye ikhiqiza ukukhishwa futhi akukho sinqumo esisusayo ngemuva. lapho ihele elihlukile lesihloko likhona eduze kwevidiyo, khipha kusuka emthonjeni ogcina ama-2 ahlukene futhi ama-frames aphuma ahlanzekile. I-AVI ayinaso isixhaso esisemthethweni se-codecs yamanje, isilinganiso sefreyimu esiguqukayo, izihloko ezithambile noma amafayela angaphezu kuka-4 GB ngaphandle kokuhlaselwa, futhi i-chunk ngayinye i-overhead ibhoboza ifayela.

Ingabe i-Image ixhasa ukubukhali?

Ifomethi ikhona, kodwa umsuka awuna-alpha ukuwunika - amafreyimu wevidiyo namakhasi ashicilelwe agcwele ukucasuka, ngakho wonke ama-pixel afika aqinile. Isixhumanisi se-alpha sisebenza ngemuva: kusho ukuthi ungasakaza isiqephu se Image ngemuva ngaphandle kokushintsha ifomethi futhi. Ukukhetha isiphetho ngokuzenzakalela kusho ukuthi uthola ifayela elivula noma kuphi ngaphandle kokucabanga ngamadivaysi angaphambili.

Ingabe amafayela Image azokhula kangako?

Okuningi kunalokho okubonayo, ngoba Image igcina wonke ama-pixel ngokugcwele kungafani nokulinganisela. I-1080p ihlala ifinyelela ku-2-5 MB futhi i-4K ihlala ifinyelela ku-6-15 MB, ngakho-ke ukukhishwa okude kusebenza ngokushesha. Lokhu kuyibhizinisi elilungile uma izithombe zidla ukukhiqizwa okuqhubekayo, futhi okubi uma zihamba ngqo kwikhasi le-web. Iphutha lemithombo yezithombe ku JPG, imithombo ekhanyayo noma eqinile iphutha ku PNG, nama-multi-page sources akhiqiza isithombe esisodwa ngakhasi.

Ingabe ihele elikhulu kakhulu AVI lizokhuphula ngokuphumelelayo?

Ama-akhawunti amahhala afinyelela ku-100 MB ngefayela ngalinye, futhi AVI ama-akhowudi asebenza kabanzi ngoba ifomu lifaka i-chunk ngayinye engaphezulu kwedatha yevidiyo. I-Premium iphakamisa i-cap ngokuqinile. Uma ihele lihlukaniswe ngama-parts amanani ngenxa ye-format ceiling, thumela ngazo zonke futhi zithathwe njengemisebenzi eyodwa.

Ngasiphi isixazululo izithombe ezikhishwayo Image ziphuma khona?

Isinqumo esifanayo njengesisuka ku AVI: 1080p AVI ikhiqiza amafreyimu angama-1920x1080 Image, 4K AVI ikhiqiza amafreyimu angama-3840x2160 Image. Umguquli awukhuphuli noma awukhuphuli isampula — ama-pixel alinganiselwa ngokuqondile kusuka ku-frame e-decoded. Sebenzisa /resize-image/ ngemuva kokukhishwa uma ufuna amathumbnails amancane.

Ingabe ngizokhipha ifreyimu ngayinye ye AVI njenge Image?

Yebo, kodwa qaphela inani lefayela - i-30 fps 1-minithi AVI ikhiqiza amafreyimu angama-1,800 Image. Siwafaka ngaphakathi kohele olulodwa lwe-ZIP ngokuzenzakalela. Kweziclips ezide, khetha "1 ngesekondi" esisetshenzisiwe (amafreyimu angama-60 ngomzuzu) noma khetha ama-timestamps athile. Ihora lama-AVI nganoma iyiphi ifreyimu lizokhiqiza izithombe ezingu-~100,000 Image.

Yebo — umbala uqokwa nge-matrix efanayo etholakalayo AVI umsuka we-stream ubonisa (BT.709 for HD, BT.2020 for 4K HDR). Ama-HDR asuka ku-tone-mapped ku-SDR uma ekhishwa ku-Image angagcina ama-HDR pixel ranges ngokusemthethweni (JPG, PNG-8). Cindezela i-high-bit PNG-16 noma i-TIFF uma ufuna ukugcina ubukhulu obubanzi be-dynamic range.

Ingabe incane ifreyimu ekhishwayo Image kwidiski?

Ingabe i-Image ekhishwayo igcina i-EXIF metadata yekhamera?

I AVI i Container ayihambisani ne-EXIF ye-frame ngayinye ngendlela ikhamera ehlala khona eyenza ngayo, ngakho i Image amafayela aphuma nge-EXIF blocks engenanto. Umguquli ufaka `creation_time` indawo ekhombisa i-source frame timestamp, ngakho ungaphinde uhlela i-bundle ngendlela ye-chronological noma ulinganise nesihloko esingezansi / izihloko zezinkomba.

Ithatha isikhathi esingakanani ukukhishwa kwefreyimu kusuka ku AVI kuya ku Image?

AVI

Amafayela e-AVI angaqukatha idatha yomsindo nevidiyo, esekelwa kabanzi kodwa enosayizi abakhulu bamafayela.

Image

Amafayela ezithombe, njenge-JPG, i-PNG, ne-GIF, agcina ulwazi olubonakalayo. Lawa mafayela angaqukatha izithombe, ihluzo, noma imifanekiso. Izithombe zisetshenziswa ezinhlelweni zokusebenza ezahlukahlukene, okuhlanganisa ukwakheka kwewebhu, imidiya yedijithali, kanye nemifanekiso yamadokhumenti, ukudlulisa okuqukethwe okubonakalayo.
