MOV ukuba TIFF Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-MOV ividiyo njenge-TIFF 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 TIFF 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-TIFF yifomati yefayili yomfanekiso ophawulweyo ukusukela ngo-1986, kwaye yifomati yokukhangela, yoshicilelo kunye nokugcina iinjineli ezimiselwe.

Ingaba izihloko zesihloko ziya kubonakala kwi-TIFF 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 TIFF 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 TIFF 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 TIFF 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-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 MOV ividiyo — i-1080p MOV ivelisa i-1920×1080 TIFF iifayili; i-4K MOV 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 MOV njenge TIFF?

Ewe, kodwa uqaphele ngobalo lwefayili - i-30fps 1-imizuzu MOV 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 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-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 MOV ivelisa ~50 GB ngokupheleleyo.

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

Isiqulathi seefayili MOV 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 MOV ukuya kwi TIFF?

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