MPG ukuba TIFF Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-MPG ividiyo njenge-TIFF imifanekiso?

Layisha phezulu i MPG kwaye umguquli ubonisa umkhethi wesakhelo-sokukhupha: isakhelo ngasinye se-Nth, isakhelo kwixesha elikhankanyiweyo, okanye isakhelo ngasinye kwisiqingatha seyure. Isakhelo ngasinye esikhethiweyo sikhowudiwe njengefayili ye TIFF kwaye iseti epheleleyo iquka uvimba we-ZIP oza kukhuphela. I-MPG ifana nenkqubo ye-MPEG ejikelezayo njenge-.mpeg — uluhlu lweeleta ezintathu luyi-DOS-era truncation, hayi ifomati eyahlukileyo. I-TIFF yifomati yefayili yomfanekiso ophawulweyo ukusukela ngo-1986, kwaye yifomati yokukhangela, yoshicilelo kunye nokugcina iinjineli ezimiselwe.

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-TIFF iifayili ngaphandle kweencwadi ezineenkcukacha?

Ukuba i MPG ayizange ibhakwe, kuba MPG ayinayo i-subtitle ekhethiweyo yokuqhuba ukuvala. Nantoni na ebonisa i MPG kwisikrini sikwimifanekiso ngokwayo, ngoko ke yiyo yonke i TIFF 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. MPG ifumana yonke i MPEG-2 imida - i-bitrate enzima, uthungelwano, akukho sihloko esicocekileyo - kunye nokungaqhelekanga kweendawo ezimbini zokukhupha ifomati enye.

Ingaba i-TIFF 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-TIFF kamva ngaphandle kokuguqula i-format kwakhona. I-TIFF iphatha i CMYK, ubunzulu be-16-bit, i-ICC efakwe ngaphakathi kunye namaxwebhu amaphepha amaninzi, eyona nto ishicilela kwaye ifuna uthungelwano lomsebenzi wokugcina.

Ingaba iifayili TIFF ziya kuba zikhulu kangakanani?

Ikhulu kunalo lonke ulindeleyo, kuba TIFF 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-TIFF yindawo yokugcina engaphezulu kwe-codec: inokuphatha i-data engacinezelwanga, i-LZW, i-ZIP okanye nakwi-JPEG, ukuya kuthi ga kwi-32 bits kwisiqhagamshelanisi ngasinye, ngeephepha ezininzi kwifayili enye.

Kunye nobunzulu obunjani isakhelo ngasinye esikhutshwe TIFF siphuma?

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

Ndingayikhupha isakhelo ngasinye esitsha kwi MPG njenge TIFF?

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

Ingaba imifanekiso ekhutshweyo TIFF iya kugcina umbala ophakamileyo MPG?

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

Yintoni ubungakanani befayili yesakhelo esitshatweyo TIFF?

Ixhomekeke kwisisombululo kunye ne TIFF 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 MPG ivelisa ~50 GB ngokupheleleyo.

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

Isiqulathi seefayili MPG asigcinanga i-EXIF yesakhelo ngasinye ngendlela ikhamera ehlala isenza ngayo, ngoko ke ii-TIFF 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 MPG ukuya kwi TIFF?

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

Ndingazikhupha iifayili kwixesha elikhankanyiweyo le MPG?

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