3GP kuya Image Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngizokhipha kanjani amafreyimu kusuka ku 3GP ividiyo njenge Image izithombe?

Layisha phezulu i-3GP futhi umguquli ubonisa isikhethi sefreyimu-sokukhipha: nganoma iyiphi ifreyimu ye-Nth, amafreyimu ezikhathini ezicacisiwe, noma ifreyimu eyodwa ngesekondi. Ifreyimu ngayinye ekhethiwe ikhodwe njengehele Image elilodwa futhi isethulo esigcwele sifakwe kwi-ZIP archive yokulayisha phezulu. I-3GP iyibhokisi le-3GPP elijwayelekile lefoni ephathekayo, lapho ividiyo idinga ukuhambisana ne-176x144 screen ne-2G data plan. Isithombe lapha siyinjongo ejwayelekile: umguquli ukhetha ifomethi ye-raster efanele umsuka endaweni yokucindezela enye kuwe.

Ingabe ngithola ama-Image amafreyimu ngaphandle kwesihloko esingezansi?

Uma nje i 3GP ayizange itshetshezwe, ngoba 3GP ayinaso isingeniso esikhethiwe sohluzo esikhethiwe sokuvala. Noma yini e3GP ebonisa esigabeni isithombe, ngakho i Image 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-3GP iphele ngezinhlamvu eziphansi kanye nesandi sokukhuluma esisezingeni eliphansi; ukuphakama kwayo ngeke kubuyisele imingwane engazange ithathwe.

Ingabe i-Image 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 Image ngemuva ngaphandle kokushintsha ifomethi futhi. Ukukhetha isiphetho ngokuzenzakalela kusho ukuthi uthola ifayela elivula noma kuphi ngaphandle kokucabanga ngamadivaysi angaphambili.

Ingabe amafayela Image azokhula kangako?

Okuningi kunalokho okubonayo, ngoba Image 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. Iphutha lemithombo yezithombe ku JPG, imithombo ekhanyayo noma eqinile iphutha ku PNG, nama-multi-page sources akhiqiza isithombe esisodwa ngakhasi.

Ngasiphi isixazululo siphuma kuso sonke ifreyimu ekhishwayo Image?

Isinqumo esifanayo njenge 3GP ividiyo — 1080p 3GP ikhiqiza amafreyimu angama-1920×1080 Image; 4K 3GP ikhiqiza amafreyimu angama-3840×2160 Image. Sebenzisa ukuguqula usayizi ngemuva kokukhipha uma ufuna amathumbnail amancane noma ama-social-media-size crops.

Ingabe ngizokhipha ifreyimu ngayinye kusuka ku 3GP njenge Image?

Yebo, kodwa uqaphele ngokubalwa kwefayela - i-30fps 1-minithi 3GP ikhiqiza amafreyimu angama-1,800 Image. Siwafaka ngokuzenzakalela ku-ZIP. Kweziclips ezide, "1 ngesekondi" (ifreyimu engu-60) noma ama-timestamps athile anikeza imiphumela elawulwayo.

Ingabe izithombe ezikhishwayo Image zizogcina umbala olinganiselwe 3GP?

Yebo — umbala uqoshwe nge-matrix esetshenziswa umsuka 3GP (BT.709 for HD, BT.2020 for 4K HDR). Ama-HDR asuka ku-tone-mapped ku-SDR uma ekhishwa ku-Image ngoba ama-Image ahlukahlukene (PNG, JPG) angagcina ama-pixels we-HDR ngokusemthethweni.

Yini ubukhulu behele lwesiphequluli esikhishwayo Image?

Kuxhomekeka kusinqumo kanye ne-Image 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 3GP kukhiqiza ~50 GB jikelele.

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

I 3GP i Container ayigcinanga i-EXIF nge-frame ngendlela ikhamera ehlala isebenza ngayo, ngakho i Image 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 3GP kuya ku Image?

Ukukhishwa kwefreyimu kushesha — 20 kuya ku-30% yesikhathi somthombo ku-pipeline ejwayelekile. Iminithi engu-5 3GP → Image iqoqo liphelela cishe ngomzuzu owodwa kungakhathaliseki inani lefreyimu, ngoba ibhodlela liyi-Image encoder, hhayi i-3GP demuxer.

Ingabe ngizokhipha amafreyimu eziqephuni ezikhethekile zesikhathi ku 3GP?

Yebo - ukhetho oluphezulu lu accepts a comma-separated list of timestamps (e.g. `00:01:23,00:05:00,00:10:42`) and produces one Image file per timestamp. Useful for chapter thumbnails, scene reference shots, or thumbnailing long lectures.

Ingabe i-3GP yami yevidiyo imfihlo ngesikhathi sokukhishwa kwefreyimu?

Yebo — imodeli yobumfihlo efanayo nezo zonke iziguqulo. Ividiyo yomsuka kanye nefreyimu ekhishwayo Image ziqhubekelwa ngabasebenza ngokuzimela futhi zicishwe ngaphakathi kwemizuzu; akukho kuhlolwa komuntu, akukho kuhlolwa kokuzivocavoca, akukho ukungena kwengxenye yesithathu.

3GP

I-3GP iyifomethi yesitsha semultimedia eyenzelwe omakhalekhukhwini be-3G. Ingagcina idatha yomsindo nevidiyo futhi ivamise ukusetshenziselwa ukudlalwa kwevidiyo yeselula.

Image

Amafayela ezithombe, njenge-JPG, i-PNG, ne-GIF, agcina ulwazi olubonakalayo. Lawa mafayela angaqukatha izithombe, ihluzo, noma imifanekiso. Izithombe zisetshenziswa ezinhlelweni zokusebenza ezahlukahlukene, okuhlanganisa ukwakheka kwewebhu, imidiya yedijithali, kanye nemifanekiso yamadokhumenti, ukudlulisa okuqukethwe okubonakalayo.
