Indlela yokuguqula MOV ukuba BMP

Inyathelo 1: Layisha eyakho MOV iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho BMP iifayile

MOV ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu i MOV 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. MOV yi Apple QuickTime isiqulathi seefayili, ethunyelwe ngo-1991 kwaye ihlala ifomati iPhone, iPad okanye Final Cut Pro umgca wexesha ubhala ngokumiselweyo. I-BMP yi-Windows Bitmap, ifomati ye-raster egqityiweyo eyenziwe kwi-Windows ukusukela ngo-1985.

Ingaba izihloko zesihloko ziya kubonakala kwi-BMP iifayili endizikhupha?

Ayinjalo ukuba ziyindawo yomxholo ophambili. I MOV igcina umxholo ophambili njengothotho lwazo oluthile kwaye umdlali uzoba ngaphaya komfanekiso ngexesha lokudlala, ngoko isakhelo esikhowudiweyo umguquli ubhala ngaphandle njenge BMP inee-pixels ezicocekileyo ezantsi. Isihloko esiphantsi esikhutshwe kwividiyo phambi kokuba ibe yi MOV siyingxaki eyahlukileyo - ngoko ziyinxalenye yomfanekiso kwaye yonke isakhelo esikhutshwe sizigcina.

Ndingayitsala enye BMP kwisiqendu ngasinye se MOV?

Ayiba iqhosha elinye, kodwa i MOV iyenza ibonakale ngokucacileyo: amaphawu esiqendu agcinwa kwisiqulathi seefayili njengeziqinisekiso zexesha ezibizwa ngokuba ziixesha, ngoko funda uluhlu lwesiqendu ngaphandle kwefayile kwaye ucofe ezo xesha kwindawo yesiqendu sexesha. Ufumana enye BMP kwisiqendu ngasinye, ngokulandelana, eyiyo indlela eqhelekileyo yokwakha imifanekiso eqingqiweyo yoshicilelo olude. Amacebo angenamagama esiqendu ashiya ukukhetha imiboniso ngemehlo endaweni. MOV yifomati ababhali abaqeqeshiweyo abacelayo, kuba ihlala iphindaphinda iinqwelo-moya ezijikelezayo nge Final Cut Pro, Premiere ne DaVinci Resolve ngaphandle kokungasebenzi kohlobo.

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.

Kunye nobunzulu obunjani isakhelo ngasinye esikhutshwe BMP siphuma?

Ugqibo olufanayo njenge MOV ividiyo — i-1080p MOV ivelisa i-1920×1080 BMP iifayili; i-4K MOV 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 MOV njenge BMP?

Ewe, kodwa uqaphele ngobalo lwefayili - i-30fps 1-imizuzu MOV 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 MOV?

Ewe — umbala uguqulwa umbala nge-matrix esetyenziswa ngumboneleli MOV (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 MOV ivelisa ~50 GB ngokupheleleyo.

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

Isiqulathi seefayili MOV 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 MOV ukuya kwi BMP?

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

Ndingazikhupha iifayili kwixesha elikhankanyiweyo le MOV?

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.

Ingaba i-MOV yevidiyo yam ifihlakeleyo ngexesha lokukhupha isakhelo?

Ewe - imodeli yobumfihlo efanayo neyokuguqula yonke. Umthombo wevidiyo kunye ne-BMP iframes ekhutshwe iqhubekeka kubasebenzi abakhuselekileyo kwaye isuswa kwimizuzu; akukho hlaziyo lomuntu, akukho qeqesho lwe-corpus, akukho kufikelela kweqela lesithathu.

MOV

I-MOV yifomathi ye-QuickTime ka-Apple, exhasa ividiyo kunye nesandi esikumgangatho ophezulu sokuhlela ngobuchwephesha.

BMP

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