MPG ukuba Image Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-MPG video njenge-Image imifanekiso?

Layisha phezulu i MPG kwaye umguquli ubonisa umkhethi wesakhelo-sokukhupha: isakhelo ngasinye se-Nth, iisakhelo kwixesha elikhankanyiweyo, okanye isakhelo ngasinye kwisiqingatha seyure. Isakhelo ngasinye esikhethiweyo sikhowudiwe njengefayili ye-Image kwaye iseti epheleleyo ifakwe kwi-ZIP yovimba wokukhuphela. I-MPG ifana nenkqubo ye-MPEG ejikelezayo njenge-.mpeg — uluhlu lweeleta ezintathu luyi-DOS-era truncation, hayi ifomati eyahlukileyo. Umfanekiso apha yinjongo eqhelekileyo: umguquli ukhetha ifomati ye raster efanelekileyo yomthombo kunokuba uvumele enye kuwe.

Kutheni iifayili zam ezikhuphiweyo zineemigca ethe tyaba ezidlula kuzo?

Kuba umthombo udityaniswe. MPG 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-Image iifayili ngaphandle kwesihloko esilandelayo?

Kuphela ukuba i MPG ayizange ibhalelwe, kuba i MPG ayinayo i-subtitle ekhethiweyo yokuqhuba ukucima. Nantoni na ebonisa i MPG kwisikrini sikwimifanekiso ngokwayo, ngoko ke yiyo yonke i Image ukukhupha ivelisa kwaye akukho mmiselo ususa emva koko. apho ifayile yesubtitle eyahlukileyo ikhona ecaleni kwevidiyo, ukhuphe ukusuka kummthombo ogcine isibini sihlukaniswe kwaye ii-frames ziphuma zicocekile. MPG ifumana yonke i MPEG-2 imida - i-bitrate enzima, uthungelwano, akukho sihloko esicocekileyo - kunye nokungaqhelekanga kweendawo ezimbini zokukhupha ifomati enye.

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.

Uphi ubunzulu be-frame nganye ekhutshweyo Image ephumayo?

Ubungakanani obufanayo ne-MPG ividiyo — i-1080p MPG ivelisa i-1920×1080 Image ii-frames; i-4K MPG ivelisa i-3840×2160 Image ii-frames. Sebenzisa uncedo lokuguqula ubungakanani emva kokukhupha ukuba ufuna ii-thumbnails ezincinci okanye ubungakanani be-social-media-crops.

Ndingayikhupha isakhelo ngasinye esitsha kwi MPG njenge Image?

Ewe, kodwa uqaphele ngobalo lweefayili - i-30fps 1-minute MPG ivelisa i-1,800 Image iifayili. Sizipakisha kwi-ZIP ngokuzenzekelayo. Kwiiclip ezide, ukhetho "1 ngomzuzwana" (iifayili ezi-60) okanye iziqinisekiso zexesha elikhankanyiweyo zinika isiphumo esiphathwayo.

Ingaba imifanekiso ekhutshweyo Image iya kugcina umbala ophakamileyo MPG?

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

Lithini 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 egqithisileyo, ukukhupha i-PNG frame nganye ye-10-minute 1080p MPG kwenza ~50 GB ngokupheleleyo.

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

Isiqulathi seefayili MPG asigcinanga i-EXIF yesakhelo ngasinye ngendlela ikhamera ehlala isebenza ngayo, ngoko ke ii-Image iifayili ziphuma nge-EXIF engenanto. Sifaka `creation_time` indawo ebonisa umhla wokugqitywa kwesakhelo somthombo ukuze uphinde ulungelelanise i-bundle ngokulandelana kokuthatha.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka ku MPG ukuya ku Image?

Ukukhupha isakhelo kukhawuleza - ngokuqhelekileyo 20 ukuya kwi 30% yobude bomthombo kwindlela eqhelekileyo yokuhambisa. Imini emihlanu MPG → Image iqela ligqiba malunga nemizuzu ngaphandle kokucinga ngobalo lwesakhelo, kuba ibhotile yengxowa yi Image encoder, hayi i MPG demuxer.

Ndingazikhuphela iifayili kwixesha elikhankanyiweyo kwi MPG?

Ewe - ukhetho oluphambili luyakwamkela uluhlu oluhlukaniswe nge-comma lweziqinisekiso zexesha (umzekelo `00:01:23,00:05:00,00:10:42`) kwaye luvelisa ifayile enye Image ngesatifiketi sexesha ngasinye. Isetyenziswa kwizifundo ezincinci zesahluko, iziganeko ezibhekisa kwimifanekiso, okanye izifundo ezide ezibonisa imifanekiso emifutshane.

MPG

IMPG lulwandiso lwefayile yeMPEG-1 okanye MPEG-2 iifayile zevidiyo. Isetyenziswa ngokuqhelekileyo ukudlala ividiyo kunye nokusasazwa.

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.
