Indlela yokuguqula MKV kuya TIFF

Isinyathelo 1: Layisha eyakho MKV amafayela usebenzisa inkinobho engenhla noma ngokuhudula bese uphonsa.

Isinyathelo 2: Chofoza inkinobho ethi 'Guqula' ukuze uqale ukuguqulwa.

Isinyathelo 3: Landa i-version yakho TIFF amafayela

MKV kuya TIFF Ukushintsha

Ngiyisusa kanjani ifreyimu kusuka ku MKV ividiyo njenge TIFF izithombe?

Layisha phezulu ihele MKV futhi umguquli ubonisa isikhethi sefremu-sokuzisusa: nganoma iyiphi ifremu ye-Nth, amafremu ezikhathini ezicacisiwe, noma ifremu eyodwa ngomzuzu. Ifremu ngayinye ekhethiwe ikhodwe njengehele TIFF elilodwa futhi lihlukaniswe njenge-ZIP yokulayisha.

Ngabe isithombe esikhishwayo TIFF siphuma ngesinqumo esingakanani?

Ukulungiswa okufanayo njenge MKV ividiyo — umsuka we-1080p ukhiqiza amafreyimu we-1920×1080 TIFF; umsuka we-4K ukhiqiza amafreyimu we-3840×2160 TIFF. Buyisela ubukhulu ngemuva kokukhishwa uma ufuna amathumbnail amancane.

Ingabe ngizokhipha yonke ifreyimu kusuka kuhele MKV njenge TIFF?

Yebo, kodwa qaphela ngokubalwa kwefayela — i-30fps 1-minute video ikhiqiza amafreyimu angu-1,800. Siwafaka ngokuzenzakalela kwi-ZIP archive. Ukusebenzisa ama-clip ade kakhulu sebenzisa "1 per second" (60 frames) noma ama-timestamps athile.

Ingabe izithombe TIFF zizogcina umbala MKV olinganiselwe?

Yebo — umbala uqokwa nge-matrix efanayo esetshenziswa umsuka MKV (BT.709 ku-HD, BT.2020 ku-4K HDR). Umsuka we-HDR u-tone-map ku-SDR uma ukhishwa ku-TIFF (i-PNG / JPG ayikwazi ukugcina ama-pixels we-HDR ngokujwayelekile).

Yini ubukhulu behele lwesiphequluli esisodwa esikhishwayo TIFF?

Kuya ngokuthi usinqumo kanye nokhetho lwe-codec. I-1080p PNG frame yi-2-5 MB; i-1080p JPG quality-85 frame yi-200-500 KB. Ukuphindaphinda nge-frame count ukuze usize i-ZIP — ku-extreme, yonke-frame extracting of a 10-min 1080p video at PNG is ~50 GB.

Ingabe i-TIFF ekhishwayo igcina ikhamera EXIF metadata?

I MKV iqoqo aligcinanga i-EXIF yefreyimu ngayinye ngendlela ikhamera ehlala isebenza ngayo, ngakho i TIFF amafayela aphuma nge-EXIF engenalutho. Sifaka `creation_time` indawo ekhombisa i-source frame timestamp ukuze uphinde uhlanganise i-bundle.

Ingabe ithatha isikhathi esingakanani ukukhishwa kwefremu kusuka ku MKV kuya ku TIFF?

Ukukhishwa kwefremu kushesha - 20-30% yosuku lokusuka ku-standard pipeline. Iminithi engu-5 MKV → TIFF iqoqo liphele ngo-1 min ngaphandle kokulinganiselwa kwefremu, ngoba i-bottleneck yi-TIFF encoder, hhayi i-demuxer.

Ingabe ngizokhipha amafreyimu ezikhathini ezikhethekile kwi MKV ividiyo?

Yebo - ukhetho oluthuthukisiwe luyamukela uhlu oluhlukaniswe nge-comma lwesikhathi sesikhathi (isibonelo `00:01:23,00:05:00,00:10:42`) futhi lukhiqiza ihele elinye TIFF ngesikhathi sesikhathi. Kuhle kuma-thumbnails wesigaba noma izikhangiso zokubhekisa.

Ingabe i-MKV yami yevidiyo ifihlakele ngesikhathi sokukhipha ifreyimu?

Yebo — imodeli yobumfihlo efanayo nezo zonke iziguqulo. Ividiyo yomthombo kanye nefreyimu ekhishwayo iphathwa abasebenza ngokuzimela futhi isuswa ngaphakathi kwemizuzu.

Kungani amafreyimu ami akhishwayo TIFF amnyama?

Kuyinto evamile ukushaya umsindo ovela emthonjeni MKV (ikhamera ihamba lapho ifreyimu ithathwa). Zama ukukhetha ama-timestamps kusuka emibonweni ehlala njalo, noma khipha amafreyimu ambalwa azungeze futhi ukhethe ocacile. Ipayipi alikhiqizi ucacile.

Ingabe le thuluzi lixhasa ukukhishwa kwefremu eyodwa ngeshintsho lendawo yokubukela?

Ayikho emfushaneni oyinhloko - sebenzisa "1 ngomzuzwana" njengenketho efana nokulinganiselwa, bese ukhetha ngokubonakalayo amafreyimu oshintsho lwesizinda. Umqolisi okhethekile wokuthola isizinda ukhona kwindlela yokuhamba.

Ingabe ngisebenzisa amafreyimu akhishwayo TIFF ngokuhweba?

Yebo, ngaphansi kwelayisense elawula umsuka MKV. Ushintsho lwefomethi alukho ubufakazi — sifaka akukho phawu lwamanzi futhi sicela akukho bufakazi belayisense ku TIFF.

MKV

I-MKV (Matroska) ingagcina amavidiyo angenamkhawulo, umsindo, kanye namathrekhi angezansi kufayela elilodwa, okulungele ama-movie.

TIFF

Amafayela e-TIFF asekela ukujula kwe-bit ephezulu kanye nokucindezelwa okungenakulahlekelwa, okulungele ukuthwebula izithombe zobungcweti kanye nokuphrinta.
