AVI kuya BMP Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngizokhipha kanjani amafreyimu kusuka ku AVI ividiyo njenge BMP izithombe?

Layisha phezulu i-AVI futhi umguquli ubonisa isikhethi sefreyimu-sokukhipha: nganoma iyiphi ifreyimu ye-Nth, amafreyimu ezikhathini ezicacisiwe, noma ifreyimu eyodwa ngesekondi. Ifreyimu ngayinye ekhethiwe ikhodwe njengehele BMP elilodwa futhi isethulo esigcwele sifakwe kwi-ZIP archive yokulayisha phezulu. AVI Microsoft Audio Video Interleave, isungulwe ngo-1992 phezu RIFF chunk format - eyodwa yezinto eziphilayo ezidala kakhulu okwamanje e circulation. I-BMP yiWindows Bitmap, ifomethi ye-raster engaqondakali efakwe ku-Windows kusukela ngo-1985.

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-BMP 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 BMP 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 amafayela BMP azokhula kangako?

Okuningi kunalokho okubonayo, ngoba BMP 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. I-BMP igcina imiqulu ye-pixel engacindezelwanga ngokuphelele ngesihloko esincane, ngakho-ke kulula ukuyihlukanisa.

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 siphuma kuso sonke ifreyimu ekhishwayo BMP?

Isinqumo esifanayo njenge AVI ividiyo — 1080p AVI ikhiqiza amafreyimu angama-1920×1080 BMP; 4K AVI ikhiqiza amafreyimu angama-3840×2160 BMP. Sebenzisa ukuguqula usayizi ngemuva kokukhipha uma ufuna amathumbnail amancane noma ama-social-media-size crops.

Ingabe ngizokhipha ifreyimu ngayinye kusuka ku AVI njenge BMP?

Yebo, kodwa uqaphele ngokubalwa kwefayela - i-30fps 1-minithi AVI ikhiqiza amafreyimu angama-1,800 BMP. Siwafaka ngokuzenzakalela ku-ZIP. Kweziclips ezide, "1 ngesekondi" (ifreyimu engu-60) noma ama-timestamps athile anikeza imiphumela elawulwayo.

Ingabe izithombe ezikhishwayo BMP zizogcina umbala olinganiselwe AVI?

Yebo — umbala uqoshwe nge-matrix esetshenziswa umsuka AVI (BT.709 for HD, BT.2020 for 4K HDR). Ama-HDR asuka ku-tone-mapped ku-SDR uma ekhishwa ku-BMP ngoba ama-BMP ahlukahlukene (PNG, JPG) angagcina ama-pixels we-HDR ngokusemthethweni.

Yini ubukhulu behele lwesiphequluli esikhishwayo BMP?

Kuxhomekeka kusinqumo kanye ne-BMP codec. Ifreyimu ye-1080p PNG ivame ukuba yi-2 kuya ku-5 MB; i-1080p JPG esezingeni-85 i-200 kuya ku-500 KB; i-4K PNG i-6 kuya ku-15 MB. Ekugcineni, ukukhipha i-PNG nganoma iyiphi ifreyimu yemizuzu engu-10 1080p AVI kukhiqiza ~50 GB jikelele.

Ingabe i-BMP ekhishwayo igcina i-EXIF camera metadata?

I AVI i Container ayigcinanga i-EXIF nge-frame ngendlela ikhamera ehlala isebenza ngayo, ngakho i BMP ifaka amafayela ngaphandle nge-EXIF engenanto. Sifaka i-`creation_time` field ekhombisa i-source frame timestamp ukuze uphinde uhlanganise i-bundle ngokulandelelana kokuthatha.

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

Ukukhishwa kwefreyimu kushesha — 20 kuya ku-30% yesikhathi somthombo ku-pipeline ejwayelekile. Iminithi engu-5 AVI → BMP iqoqo liphelela cishe ngomzuzu owodwa kungakhathaliseki inani lefreyimu, ngoba ibhodlela liyi-BMP encoder, hhayi i-AVI demuxer.

Ingabe ngizokhipha amafreyimu eziqephuni ezikhethekile zesikhathi ku AVI?

Yebo - ukhetho oluphezulu lu accepts a comma-separated list of timestamps (e.g. `00:01:23,00:05:00,00:10:42`) and produces one BMP file per timestamp. Useful for chapter thumbnails, scene reference shots, or thumbnailing long lectures.
