DivX kuya PNG Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngizokhipha kanjani amafreyimu kusuka ku DivX ividiyo njenge PNG izithombe?

Layisha phezulu i-DivX futhi umguquli ubonisa isikhethi sefreyimu-sokukhipha: nganoma iyiphi ifreyimu ye-Nth, amafreyimu ezikhathini ezicacisiwe, noma ifreyimu eyodwa ngesekondi. Ifreyimu ngayinye ekhethiwe ikhodwe njengehele PNG elilodwa futhi isethulo esigcwele sifakwe kwi-ZIP archive yokulayisha phezulu. I-DivX ibiza i-codec hhayi ibhokisi — i-MPEG-4 Part 2 isebenzisa i-DVD eyisikhashana ku-CD eyodwa ekhona ngo-1999. I-PNG yakhiwa ngo-1996 njengento eshintshayo engekho emthethweni ye-GIF, futhi yashintsha ibe yifomethi yesithombe esingenalutho esizenzakalelayo se-web.

Kungani amafreyimu ami akhishwayo anemigqa ejikelezayo edlula kuwo?

Ngenxa yokuthi umsuka uxhunywe. DivX okuqukethwe kusuka ku-broadcast ne-DVD era igcina ama-fields amabili aphakathi nendawo aphezulu ngefremu ngayinye, athathwe ngengxenye engu-50 yesithupha, futhi i-still ekhishwa ngokuqondile ibonisa ukuthi zombili zixhunywe ndawonye njenge-combing nganoma yini ehambayo. Vumela u-deinterlacing ngaphambi kokukhipha futhi i-still ngayinye ikhiwa kusuka ku-frame eqhubekayo evuselelwe.

Ingabe ngithola ama-PNG amafreyimu ngaphandle kwesihloko esingezansi?

Uma nje i DivX ayizange itshetshezwe, ngoba DivX ayinaso isingeniso esikhethiwe sohluzo esikhethiwe sokuvala. Noma yini eDivX ebonisa esigabeni isithombe, ngakho i PNG ngayinye ikhiqiza ukukhishwa futhi akukho sinqumo esisusayo ngemuva. lapho ihele elihlukile lesihloko likhona eduze kwevidiyo, khipha kusuka emthonjeni ogcina ama-2 ahlukene futhi ama-frames aphuma ahlanzekile. I-DivX idinga i-bitrate ephindwe kabili kune-H.264 ukuze ikwazi ukukhiqiza ngekhwalithi efanayo futhi ayinakho indlela ye-HDR, 10-bit umbala noma izixazululo ezingaphezu kwe-1080p.

Ingabe i-PNG ixhasa ukubukhali?

Ifomethi ikhona, kodwa umsuka awuna-alpha ukuwunika - amafreyimu wevidiyo namakhasi ashicilelwe agcwele ukucasuka, ngakho wonke ama-pixel afika aqinile. Isixhumanisi se-alpha sisebenza ngemuva: kusho ukuthi ungasakaza isiqephu se PNG ngemuva ngaphandle kokushintsha ifomethi futhi. I-PNG iyisinqumo esifanele sezithombe-skrini, amalogo, umdwebi we-line kanye nanoma yini eneziphetho eziqinile noma ezicacile — akukho ukusakaza, akukho umbala obandayo.

Ingabe amafayela PNG azokhula kangako?

Okuningi kunalokho okubonayo, ngoba PNG igcina wonke ama-pixel ngokugcwele kungafani nokulinganisela. I-1080p ihlala ifinyelela ku-2-5 MB futhi i-4K ihlala ifinyelela ku-6-15 MB, ngakho-ke ukukhishwa okude kusebenza ngokushesha. Lokhu kuyibhizinisi elilungile uma izithombe zidla ukukhiqizwa okuqhubekayo, futhi okubi uma zihamba ngqo kwikhasi le-web. I-PNG isebenzisa ukucindezeleka kwe-DEFLATE phezu kwemigqa yokuskena ehlolwe, ngakho wonke ama-pixel ahlala ngokugcwele, kanye ne-8-bit alfa channel ephelele.

Ingabe ihele elikhulu kakhulu DivX lizokhuphula ngokuphumelelayo?

Ama-akhawunti amahhala afinyelela ku-100 MB ngefayela ngalinye, futhi DivX ama-akhowudi asebenza kabanzi ngoba ifomu lifaka i-chunk ngayinye engaphezulu kwedatha yevidiyo. I-Premium iphakamisa i-cap ngokuqinile. Uma ihele lihlukaniswe ngama-parts amanani ngenxa ye-format ceiling, thumela ngazo zonke futhi zithathwe njengemisebenzi eyodwa.

Ngasiphi isixazululo siphuma kuso sonke ifreyimu ekhishwayo PNG?

Isinqumo esifanayo njenge DivX ividiyo — 1080p DivX ikhiqiza amafreyimu angama-1920×1080 PNG; 4K DivX ikhiqiza amafreyimu angama-3840×2160 PNG. Sebenzisa ukuguqula usayizi ngemuva kokukhipha uma ufuna amathumbnail amancane noma ama-social-media-size crops.

Ingabe ngizokhipha ifreyimu ngayinye kusuka ku DivX njenge PNG?

Yebo, kodwa uqaphele ngokubalwa kwefayela - i-30fps 1-minithi DivX ikhiqiza amafreyimu angama-1,800 PNG. Siwafaka ngokuzenzakalela ku-ZIP. Kweziclips ezide, "1 ngesekondi" (ifreyimu engu-60) noma ama-timestamps athile anikeza imiphumela elawulwayo.

Ingabe izithombe ezikhishwayo PNG zizogcina umbala olinganiselwe DivX?

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

Yini ubukhulu behele lwesiphequluli esikhishwayo PNG?

Kuxhomekeka kusinqumo kanye ne-PNG codec. Ifreyimu ye-1080p PNG ivame ukuba yi-2 kuya ku-5 MB; i-1080p JPG esezingeni-85 i-200 kuya ku-500 KB; i-4K PNG i-6 kuya ku-15 MB. Ekugcineni, ukukhipha i-PNG nganoma iyiphi ifreyimu yemizuzu engu-10 1080p DivX kukhiqiza ~50 GB jikelele.

Ingabe i-PNG ekhishwayo igcina i-EXIF camera metadata?

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

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

Ukukhishwa kwefreyimu kushesha — 20 kuya ku-30% yesikhathi somthombo ku-pipeline ejwayelekile. Iminithi engu-5 DivX → PNG iqoqo liphelela cishe ngomzuzu owodwa kungakhathaliseki inani lefreyimu, ngoba ibhodlela liyi-PNG encoder, hhayi i-DivX demuxer.

DivX

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

PNG

Amafayela we-PNG ahambisana nokubukeka okucacile futhi asebenzisa ukucindezeleka okungalahleki, okwenza kube ngcono kakhulu kuma-graphic, amalogo, nama-screenshots.
