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

Ndizikhuphele njani iifayili nganye kwi MOV njenge BMP imifanekiso?

Layisha phezulu ifayili MOV kwaye umguquli ubonisa umkhethi we-frame-extraction: i-frame nganye ye-Nth, i-frames kwi-timestamps ekhankanyiweyo, okanye i-frame enye ngesekondi. I-frame nganye ekhethiweyo i-decoded ukusuka kwi-MOV video stream, i-encoded njengefayili ehlukileyo ye BMP, kwaye i-bundled njenge-ZIP yokukhuphela ezantsi. 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 ezingaphantsi ziya kubonakala kwi BMP iifayili endizikhuphayo?

Ayinjalo ukuba ziyindawo ebonakalayo yokulandela umbhalo osezantsi ephepheni. I MOV igcina umbhalo osezantsi ephepheni njengendlela yabo yokuhamba kwaye umdlali uzoba phezu komfanekiso ngexesha lokudlala, ngoko ke isakhelo esikhowudiweyo umguquli ubhala ngaphandle njenge BMP inee-pixels ezicocekileyo ezantsi. Isihloko esingaphantsi esikhutshwe kwividiyo phambi kokuba ibe yi MOV siyinto eyahlukileyo - ngoko ziyinxalenye yomfanekiso kwaye yonke isakhelo esikhutshwe sigcina ezi.

Ndingayitsala enye BMP ngaphandle kwesihloko ngasinye se MOV?

Ayiba iqhosha elinye, kodwa i MOV iyenza ibonakale icacile: iimpawu zesiqendu zigcinwa kwisiqulathi seefayili njengeziphawuli zexesha ezibizwa ngokuba zii-timestamps, ngoko funda uluhlu lwesiqendu ngaphandle kwefayile kwaye ucofe ezixesha kwindawo ye-timestamp. Ufumana enye BMP kwisiqendu ngasinye, ngokulandelana, eyiyo indlela eqhelekileyo yokwakha imifanekiso eqingqiweyo yoshicilelo olude. Amacebo angenamanqaku esiqendu ashiya ukukhetha imiboniso ngemehlo endaweni. MOV yifomati ababhali abaqeqeshiweyo becela, kuba ihlala iphinda ijikeleze-ihambo 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.

Yiyiphi i-resoluton ephuma kuyo imifanekiso ekhutshwe BMP?

Ugqibo olufanayo njengomthombo MOV: i-1080p MOV ivelisa i-1920x1080 BMP ii-frames, i-4K MOV ivelisa i-3840x2160 BMP ii-frames. Umguquli awukhuphi ubungakanani okanye awukhuphi i-sample — ubungakanani be-pixel butsalwa ngqo kwi-frame eyenziwe ukuba isebenze. Sebenzisa /resize-image/ emva kokukhupha ukuba ufuna ii-thumbnails ezincinci.

Ndingayikhupha isakhelo ngasinye se MOV njenge BMP?

Ewe, kodwa uqaphele inani lefayili - i-30 fps 1-minute MOV ivelisa i-1,800 BMP iifayili. Sizifaka kwi-ZIP archive epheleleyo ngokuzenzekelayo. Kwiiclip ezide, khetha "1 ngesekondi" emiselweyo (i-60 iifayili ngesekondi) okanye ukhethe iziqinisekiso zexesha ezikhethekileyo. Iyure ye MOV kwi-frame nganye iza kwenza ~100,000 BMP imifanekiso.

Ingaba i-BMP igcina umbala ophakamileyo we-MOV?

Ewe - umbala uguqulwa kwikhowudi nge-matrix efanayo ebonisa umthombo MOV (BT.709 ye-HD, BT.2020 ye-4K HDR). Amacebo e-HDR afana ne-tone-mapped kwi-SDR xa ekhutshwa kwi-BMP engagcinanga amanqanaba e-HDR pixels ngokusemthethweni (JPG, PNG-8). I-high-bit PNG-16 okanye TIFF i target ukuba ufuna ukugcina uluhlu olubanzi olunamandla.

Ingaba i-BMP isakhelo esikhuphiweyo sikhulu kangakanani na kwi-disk?

Kuxhomekeke kwisisombululo kunye nokhetho lwe-BMP codec: i-1080p PNG frame yi-2-5 MB engenakulahleka, i-1080p JPG kwi-quality 85 yi-200-500 KB. Yahlula nge-frame count ukuze ubungakanani be-ZIP — kwinqanaba eliphezulu, i-PNG ephuma kwi-frame nganye ye-10-minute 1080p MOV imalunga ne-50 GB kwaye ihlukaniswe phakathi kwe-ZIPs ezininzi.

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

I MOV ibhokisi ayithabathanga i-EXIF yesakhelo ngasinye ngendlela ikhamera ehlala isenza ngayo, ngoko ke i BMP iifayili ziphuma zingenazinto eziqhotyoshelweyo ze-EXIF. Umguquli ufaka `creation_time` indawo ebonisa kwi-source frame timestamp, ukuze uphinde ulungelelanise i-bundle ngokulandelana kwexesha okanye uqhagamshelane nesihloko esingaphantsi / nabaphawuli besahluko.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka ku MOV ukuya ku BMP?

Isakhelo sokukhupha ikhowudi sikhawulezayo - ngokuqhelekileyo 20- 30% yobude bomthombo. Imini emihlanu MOV -> BMP iqela ligqiba malunga nemizuzu emi- 1 ngaphandle kokuba iframes ezininzi ukhetha, kuba ibhotile yengxowa ye BMP encoder ibhala iifayile ezininzi ezincinci ngokuthe tye, hayi i MOV demuxer.

Ndingazikhuphela iifayili kwixesha elichanekileyo elingaphakathi kwi-MOV yevidiyo?

Ewe - ukhetho oluphambili lwesiqinisekiso sexesha livuma uluhlu oluhlukaniswe nge-comma (umzekelo `00:01:23, 00:05:00, 00:10:42.5`) kwaye luvelisa ifayile enye BMP ngesiqinisekiso sexesha. Isetyenziswa kwiziqendu ezincinci, iziganeko ezibhekisa kwimifanekiso, okanye ukwakha iphepha loqhagamshelwano lokujonga kwakhona.

Ingaba i MOV yam ifihlakeleyo xa ikhutshwa isakhelo?

Ewe - imodeli yobumfihlo efanayo njengengguqulo nganye. Umsuka MOV kunye ne BMP ekhutshweyo iqhutywa kubasebenzi ababekwe ngokukodwa kwaye icinywe kwimizuzu yokuphela.
