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 Image iifayile

MOV ukuba Image Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-MOV ividiyo njenge-Image 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 Image 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. Umfanekiso apha yinjongo eqhelekileyo: umguquli ukhetha ifomati ye raster efanelekileyo yomthombo kunokuba uvumele enye kuwe.

Ingaba izihloko zesihloko ziya kubonakala kwi-Image 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 Image 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 Image 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 Image 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 i-Image ixhasa ukubonakaliswa ngokucacileyo?

Ifomati isebenza, kodwa umbhali akafuni i-alpha ukunika - ii-frames zevidiyo kunye neephepha ezibonisiweyo zicacile ngokupheleleyo, ngoko ke zonke ii-pixels zifika ziqinile. Isiqhagamshelanisi se-alpha sihlala sisetyenziswa emva koko: kuthetha ukuba ungacima into ephuma kwi-Image kamva ngaphandle kokuguqula i-format kwakhona. Ukukhetha isiphelo ngokuzenzekelayo kuthetha ukuba ufumana ifayile evula naphi na ngaphandle kokufuna ukuqonda malunga nee codecs kuqala.

Ingaba iifayili Image ziya kuba zikhulu kangakanani?

Ikhulu kunalo lonke ulindeleyo, kuba Image 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. Iindawo ezivela kuzo iimifanekiso zimiselwe kwi-JPG, iindawo ezivela kuzo ezibonisa ngaphaya okanye imida eqinileyo zimiselwe kwi-PNG, kwaye iindawo ezivela kuzo iiphepha ezininzi zivelisa umfanekiso omnye kwiphepha ngalinye.

Kunye nobunzulu obunjani isakhelo ngasinye esikhutshwe Image siphuma?

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

Ndingayikhupha isakhelo ngasinye esitsha kwi MOV njenge Image?

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

Ingaba imifanekiso ekhutshweyo Image 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-Image kuba i-Image ifomati (PNG, JPG) ayikwazi ukugcina i-HDR pixel ranges ngokusemthethweni.

Yintoni ubungakanani befayili yesakhelo esitshatweyo Image?

Ixhomekeke kwisisombululo kunye ne Image 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-Image ekhutshiweyo igcina i-EXIF metadata yekhamera?

Isiqulathi seefayili MOV asigcinanga i-EXIF yesakhelo ngasinye ngendlela ikhamera ehlala isenza ngayo, ngoko ke ii-Image 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 Image?

Ukukhupha iframe kukhawuleza - ngokuqhelekileyo 20 ukuya 30% yobude bomthombo kwindlela eqhelekileyo yokuhambisa. Imizuzu emihlanu MOV → Image iqela ligqiba malunga nemizuzu enye ngaphandle kokucinga ngobalo lweeframe, kuba ibhotile yengxowa yi Image 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 Image ngesatifiketi sexesha. Esetyenziswa kwizifundo ezincinci zesifundo, iziganeko ezibhekisa kwimifanekiso, okanye izifundo ezide ezibonisa imifanekiso.

MOV

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

Image

Iifayile zemifanekiso, ezifana neJPG, PNG, kunye neGIF, zigcina ulwazi olubonakalayo. Ezi fayile zingaqulatha iifoto, imizobo, okanye imifanekiso. Imifanekiso isetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanya uyilo lwewebhu, imidiya yedijithali, kunye nemifanekiso yamaxwebhu, ukuhambisa umxholo obonakalayo.
