Indlela yokuguqula DivX kuya BMP

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

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

Isinyathelo 3: Landa i-version yakho BMP amafayela

DivX kuya BMP Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngizokhipha kanjani amafreyimu kusuka ku DivX ividiyo njenge BMP izithombe?

Layisha phezulu ihele DivX futhi umguquli ubonisa isikhethi sefreyimu-sokukhipha: nganoma iyiphi ifreyimu ye-Nth, amafreyimu ezikhathini ezicacisiwe, noma ifreyimu eyodwa ngesekondi. Ifreyimu ngayinye ekhethiwe ikhodwe njengehele BMP elilodwa futhi lihlukaniswe njenge-ZIP yokulayisha phezulu.

Isithombe esikhishwayo BMP siphuma kanjani ngesinqumo?

Isinqumo esifanayo njenge DivX ividiyo — 1080p umsuka ukhiqiza amafreyimu angama-1920×1080 BMP; 4K umsuka ukhiqiza amafreyimu angama-3840×2160 BMP. Buyisela ubukhulu ngemuva kokukhishwa uma ufuna amathumbnail amancane.

Ingabe ngizokhipha yonke ifreyimu kusuka kuhele DivX njenge BMP?

Yebo, kodwa uqaphele ngokubalwa kwefayela - i-30fps 1-minute video ikhiqiza amafreyimu angama-1,800. Siwafaka ngaphakathi kwe-ZIP archive ngokuzenzakalela. Kweziqephu ezide sebenzisa "1 ngesekondi" (ifreyimu engu-60) noma ama-timestamps athile.

Ingabe izithombe BMP zizogcina umbala DivX olinganiselwe?

Yebo — umbala uqoshwe nge-matrix efanayo esetshenziswa umsuka DivX (BT.709 for HD, BT.2020 for 4K HDR). Ama-HDR asuka ku-tone-mapped ku-SDR uma ekhishwa ku-BMP (i-PNG / JPG ayikwazi ukugcina ama-pixels we-HDR ngokusemthethweni).

Yini ubukhulu behele lwesiphequluli esikhishwayo BMP?

Kuxhomekeka kusinqumo kanye nokukhetha i-codec. Ifreyimu ye-1080p PNG iyizi-2-5 MB; ifreyimu ye-1080p JPG esezingeni eliphakeme-85 iyizi-200-500 KB. Yiphinda ngenombolo yefreyimu ukuze usize i-ZIP — ku-extreme, ukukhipha ifreyimu ngayinye yevidiyo ye-10-min 1080p ku-PNG ku-~50 GB.

Ingabe i-BMP ekhishwayo igcina i-EXIF metadata yekhamera?

I DivX i Container ayigcinanga i-EXIF nge-frame ngendlela ikhamera ehlala isebenza ngayo, ngakho i BMP ifaka amafayela ngaphandle nge-EXIF engenanto. Sifaka i-`creation_time` field ekhombisa i-source frame timestamp ukuze uphinde uhlanganise i-bundle.

Ithatha isikhathi esingakanani ukukhishwa kwefreyimu kusuka ku DivX kuya ku BMP?

Ukukhishwa kwefreyimu kushesha — 20-30% yesikhathi somthombo ku-pipeline ejwayelekile. Iminithi engu-5 DivX → BMP iqoqo liphele ngo-1 min ngaphandle kokubala kwefreyimu, ngoba i-bottleneck yi-BMP encoder, hhayi i-demuxer.

Ingabe ngizokhipha amafreyimu eziqephuni ezikhethekile zesikhathi kwi-DivX video?

Yebo - isinqumo esiphakeme si accepts a comma-separated list of timestamps (e.g. `00:01:23,00:05:00,00:10:42`) and produces one BMP file per timestamp. Useful for chapter thumbnails or scene reference shots.

Ingabe i-DivX yami yevidiyo imfihlo ngesikhathi sokukhishwa kwefreyimu?

Yebo — imodeli yobumfihlo efanayo nezo zonke iziguquli. Ividiyo yomsuka kanye nefreyimu ekhishwayo iphathwa ngabasebenza ngokuzimela futhi isuswa ngaphakathi kwemizuzu.

Kungani ama-BMP amafreyimu ami akhishwa amnyama?

Kuyinto evamile ukushaya isithombe kusuka kumthombo DivX (ikhamera ihamba lapho ifreyimu ithathwa khona). Zama ukukhetha ama-timestamps kusuka emibonweni ehlala njalo, noma ukhiphe amafreyimu ambalwa azungeze futhi ukhethe ocacile kakhulu. Ipayipi alikhiqizi ucacile.

Ingabe lesi sisetshenziswa sisekela ukukhishwa kwefremu eyodwa ngeshintsho lendawo?

Ayikho ku- basic flow — sebenzisa i- "1 ngesekondi" option njenge-approximation, bese ukhetha ngokubonakalayo amafreyimu woshintsho lwesizinda. Isizinda esikhethekile sokuthola isizinda sikhona kwi roadmap.

Ingabe ngisebenzisa amafreyimu akhishwayo BMP ngebhizinisi?

Yebo, ngaphansi kwelayisense elilawula i-DivX isihloko somthombo. Ushintsho lwefomethi alutholi icala — sifaka uphawu lwamanzi futhi sicela icala olungasebenzi kwi-BMP okuqukethwe.

DivX

I-DivX ubuchwepheshe bokucindezela ividiyo obuvumela ukucindezelwa kwevidiyo kwekhwalithi ephezulu enosayizi bamafayela amancane uma kuqhathaniswa. Ivame ukusetshenziselwa ukusatshalaliswa kwamavidiyo aku-inthanethi.
