DivX ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-DivX ividiyo njenge-BMP imifanekiso?

Layisha phezulu i DivX kwaye umguquli ubonisa umkhethi wesakhelo-sokukhupha: isakhelo ngasinye se-Nth, isakhelo kwixesha elikhankanyiweyo, okanye isakhelo ngasinye kwisiqingatha seyure. Isakhelo ngasinye esikhethiweyo sikhowudiwe njengefayili ye BMP kwaye iseti epheleleyo iquka uvimba we-ZIP oza kukhuphela. I-DivX ibiza i-codec kunokuba i-container - i-MPEG-4 Inxalenye 2 yokusebenza eyenza ukukhupha i DVD kwi CD enye ekwaziyo malunga ne-1999. I-BMP yi-Windows Bitmap, ifomati ye-raster egqityiweyo eyenziwe kwi-Windows ukusukela ngo-1985.

Kutheni iifayili zam ezikhuphiweyo zineemigca ethe tyaba ezidlula kuzo?

Kuba umthombo udityaniswe. DivX 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-BMP iifayili ngaphandle kweencwadi ezineenkcukacha?

Ukuba i DivX ayizange ibhakwe, kuba DivX ayinayo i-subtitle ekhethiweyo yokuqhuba ukuvala. Nantoni na ebonisa i DivX kwisikrini sikwimifanekiso ngokwayo, ngoko ke yiyo yonke i BMP ukukhupha ivelisa kwaye akukho mmiselo ususa emva koko. apho ifayile yesubtitle eyahlukileyo ikhona ecaleni kwevidiyo, ukhuphe ukusuka kumcebo ogcine isibini sihlukaniswe kwaye ii-frames ziphuma zicocekile. I-DivX ifuna ukuphindaphindwa kabini kwe-bitrate ye-H.264 yomgangatho ofanayo kwaye ayinayo indlela ye-HDR, 10-bit umbala okanye ugqibo ngaphezulu kwe-1080p.

Ingaba iifayili BMP ziya kuba zikhulu kangakanani?

Ikhulu kunalo lonke ulindeleyo, kuba BMP 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. I-BMP igcina imiqolo ye-pixel engacinezelwanga ngokupheleleyo enesihloko esincinci, oko kukuthi, yintoni eyenza kube lula ukuchaza ngeenkcukacha.

Ingaba ifayili enkulu kakhulu DivX iyakulayishwa ngokuphumelelayo?

Ii-akhawunti ezikhululekileyo zifikelela kwi-100 MB kwifayili nganye, DivX 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.

Kunye nobunzulu obunjani isakhelo ngasinye esikhutshwe BMP siphuma?

Ugqibo olufanayo njenge DivX ividiyo — i-1080p DivX ivelisa i-1920×1080 BMP iifayili; i-4K DivX ivelisa i-3840×2160 BMP iifayili. Sebenzisa uncedo lokuphinda ubungakanani emva kokukhupha ukuba ufuna iithumbnails ezincinci okanye ubungakanani bokusika i-social-media.

Ndingayikhupha isakhelo ngasinye esitsha kwi DivX njenge BMP?

Ewe, kodwa uqaphele ngobalo lwefayili - i-30fps 1-imizuzu DivX ivelisa i-1,800 BMP iifayili. Sizifaka kwi-ZIP ngokuzenzekelayo. Kwiiclip ezide, ukhetho "1 ngomzuzwana" (iifayili ezi-60) okanye i-timestamps ekhethekileyo inika isiphumo esilawulwayo.

Ingaba imifanekiso ekhutshweyo BMP iya kugcina umbala ophakamileyo DivX?

Ewe — umbala uguqulwa umbala nge-matrix esetyenziswa ngumboneleli DivX (BT.709 ye-HD, BT.2020 ye-4K HDR). Umboneleli we-HDR udweliswe nge-tone-map kwi-SDR xa ukhupha kwi-BMP kuba i-BMP ifomati (PNG, JPG) ayikwazi ukugcina i-HDR pixel ranges ngokusemthethweni.

Yintoni ubungakanani befayili yesakhelo esitshatweyo BMP?

Ixhomekeke kwisisombululo kunye ne BMP 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 ebuhlungu, i-PNG frame nganye yokukhupha i-10-minute 1080p DivX ivelisa ~50 GB ngokupheleleyo.

Ingaba i-BMP ekhutshiweyo igcina i-EXIF metadata yekhamera?

Isiqulathi seefayili DivX asigcinanga i-EXIF yesakhelo ngasinye ngendlela ikhamera ehlala isenza ngayo, ngoko ke ii-BMP iifayili ziphuma nge-EXIF engenanto. Sifaka `creation_time` indawo ebonisa i-source frame timestamp ukuze uphinde ulungelelanise i-bundle ngokulandelana kokuthatha.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka kwi DivX ukuya kwi BMP?

Ukukhupha iframe kukhawuleza - ngokuqhelekileyo 20 ukuya 30% yobude bomthombo kwindlela eqhelekileyo yokuhambisa. Imizuzu emihlanu DivX → BMP iqela ligqiba malunga nemizuzu enye ngaphandle kokucinga ngobalo lweeframe, kuba ibhotile yengxowa yi BMP encoder, hayi i DivX demuxer.

Ndingazikhupha iifayili kwixesha elikhankanyiweyo le DivX?

Ewe - ukhetho oluphambili luyakwamkela uluhlu oluhlukaniswe nge-comma lweziqinisekiso zexesha (umzekelo `00:01:23,00:05:00,00:10:42`) kwaye luvelise ifayile enye BMP ngesatifiketi sexesha. Esetyenziswa kwizifundo ezincinci zesifundo, iziganeko ezibhekisa kwimifanekiso, okanye izifundo ezide ezibonisa imifanekiso.

DivX

I-DivX yayiyi-codec eyenza ukuba i-feature-length video ilungele i-CD, kwaye ihlala ivela kwiifayili ze-AVI ezidala.

BMP

Iifayile zeBMP zigcina imifanekiso kwifomathi yebitmap engacinezelwanga, nto leyo ebangela ukuba iifayile zibe nkulu kodwa zibe nomgangatho ogqibeleleyo.
