DivX ukuba Image Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhuphele njani iifayili nganye kwi DivX njenge Image imifanekiso?

Layisha phezulu ifayili DivX kwaye umguquli ubonisa umkhethi we-frame-extraction: i-frame nganye ye-Nth, i-frames kwi-timestamps ekhankanyiweyo, okanye i-frame enye ngesekondi. I-frame nganye ekhethiweyo i-decoded ukusuka kwi-DivX video stream, i-encoded njengefayili ehlukileyo ye Image, kwaye i-bundled njenge-ZIP yokukhuphela ezantsi. I-DivX ibiza i-codec kunokuba i-container - i-MPEG-4 Inxalenye 2 yokusebenza eyenza ukukhupha i DVD kwi CD enye ekwaziyo malunga ne-1999. Umfanekiso apha yinjongo eqhelekileyo: umguquli ukhetha ifomati ye raster efanelekileyo yomthombo kunokuba uvumele enye kuwe.

Kutheni iifayili zam ezikhuphiweyo zineemigca ethe tyaba ezidlula kuzo?

Kuba umthombo udityaniswe. DivX imixholo evela kwixesha le-DVD nele-broadcast igcina iindawo ezimbini zomphakamo wesiqendu kwiframe nganye, ithathwe kwishumi elinesixhenxe sesekondi, kwaye i-still ethe tyaba ibonisa zombini ezidityaniswe njenge-combing nantoni na ehambayo. Yenza u-deinterlacing phambi kokukhupha kwaye i-still nganye ikhiwa ukusuka kwi-frame eqhubekayo eyenziwe kwakhona.

Ndingazifumana njani ii-Image iifayili ngaphandle kwesihloko esilandelayo?

Kuphela ukuba i DivX ayizange ibhakwe, kuba i DivX ayinayo i-subtitle ekhethiweyo yokuqhuba ukuvala. Nantoni na ebonisa i DivX kwisikrini sikwimifanekiso ngokwayo, ngoko ke yiyo yonke i Image ukukhupha ivelisa kwaye akukho mmiselo ususa emva koko. apho ifayile yesubtitle eyahlukileyo ikhona ecaleni kwevidiyo, ukhuphe ukusuka kumthombo ogcine isibini sihlukaniswe kwaye ii-frames ziphuma zicocekile. I-DivX ifuna ukuphindaphindwa kabini kwe-bitrate ye-H.264 yomgangatho ofanayo kwaye ayinayo indlela ye-HDR, 10-bit umbala okanye ugqibo ngaphezulu kwe-1080p.

Ingaba i-Image 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-Image kamva ngaphandle kokuguqula i-format kwakhona. Ukukhetha isiphelo ngokuzenzekelayo kuthetha ukuba ufumana ifayile evula naphi na ngaphandle kokufuna ukuqonda malunga nee codecs kuqala.

Ingaba iifayili Image ziya kuba zikhulu kangakanani?

Ikhulu kunalo lonke ulindeleyo, kuba Image 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. Iindawo ezivela kuzo iimifanekiso zimiselwe kwi-JPG, iindawo ezivela kuzo ezibonisa ngaphaya okanye imida eqinileyo zimiselwe kwi-PNG, kwaye iindawo ezivela kuzo iiphepha ezininzi zivelisa umfanekiso omnye kwiphepha ngalinye.

Ingaba ifayili enkulu kakhulu DivX iyakulayishwa ngokuphumelelayo?

Ii-akhawunti ezikhululekileyo zifikelela kwi-100 MB kwifayili nganye, DivX amacebo ahamba phezulu ngenxa yokuba ifomati ihambisa i-chunk nganye ebalulekileyo engaphezulu kwe-data yevidiyo. I-Premium iphakamisa i-cap ngokucacileyo. Ukuba ifayile ihlukaniswe ibe ziinxalenye ezilinganisayo ngenxa yefomati ye-ceiling, ulayishe nganye nganye kwaye zithathwe njengemisebenzi enye.

Yiyiphi i-resoluton ephuma kuyo imifanekiso ekhutshwe Image?

Ugqibo olufanayo njengomthombo DivX: i-1080p DivX ivelisa i-1920x1080 Image ii-frames, i-4K DivX ivelisa i-3840x2160 Image ii-frames. Umguquli awukhuphi ubungakanani okanye awukhuphi i-sample — ubungakanani be-pixel butsalwa ngqo kwi-frame eyenziwe ukuba isebenze. Sebenzisa /resize-image/ emva kokukhupha ukuba ufuna ii-thumbnails ezincinci.

Ndingayikhupha isakhelo ngasinye se DivX njenge Image?

Ewe, kodwa uqaphele inani lefayili - i-30 fps 1-minute DivX ivelisa i-1,800 Image iifayili. Sizifaka kwi-ZIP archive epheleleyo ngokuzenzekelayo. Kwiiclip ezide, khetha "1 ngesekondi" emiselweyo (i-60 iifayili ngesekondi) okanye ukhethe iziqinisekiso zexesha ezikhethekileyo. Iyure ye DivX kwi-frame nganye iza kwenza ~100,000 Image imifanekiso.

Ingaba i-Image igcina umbala ophakamileyo we-DivX?

Ewe - umbala uguqulwa kwikhowudi nge-matrix efanayo ebonisa umthombo DivX (BT.709 ye-HD, BT.2020 ye-4K HDR). Amacebo e-HDR afana ne-tone-mapped kwi-SDR xa ekhutshwa kwi-Image engagcinanga amanqanaba e-HDR pixels ngokusemthethweni (JPG, PNG-8). I-high-bit PNG-16 okanye TIFF i target ukuba ufuna ukugcina uluhlu olubanzi olunamandla.

Ingaba i-Image isakhelo esikhuphiweyo sikhulu kangakanani na kwi-disk?

Kuxhomekeke kwisisombululo kunye nokhetho lwe-Image codec: i-1080p PNG frame yi-2-5 MB engenakulahleka, i-1080p JPG kwi-quality 85 yi-200-500 KB. Yahlula nge-frame count ukuze ubungakanani be-ZIP — kwinqanaba eliphezulu, i-PNG ephuma kwi-frame nganye ye-10-minute 1080p DivX imalunga ne-50 GB kwaye ihlukaniswe phakathi kwe-ZIPs ezininzi.

Ingaba i-Image ekhutshweyo igcina i-EXIF metadata yekhamera?

I DivX ibhokisi ayithabathanga i-EXIF yesakhelo ngasinye ngendlela ikhamera ehlala isenza ngayo, ngoko ke i Image iifayili ziphuma zingenazinto eziqhotyoshelweyo ze-EXIF. Umguquli ufaka `creation_time` indawo ebonisa kwi-source frame timestamp, ukuze uphinde ulungelelanise i-bundle ngokulandelana kwexesha okanye uqhagamshelane nesihloko esingaphantsi / nabaphawuli besahluko.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka ku DivX ukuya ku Image?

Isakhelo sokukhupha ikhowudi sikhawulezayo - ngokuqhelekileyo 20- 30% yobude bomthombo. Imini emihlanu DivX -> Image iqela ligqiba malunga nemizuzu emi- 1 ngaphandle kokuba iframes ezininzi ukhetha, kuba ibhotile yengxowa ye Image encoder ibhala iifayile ezininzi ezincinci ngokuthe tye, hayi i DivX demuxer.

DivX

I-DivX yitekhnoloji yocinezelo lwevidiyo evumela ucinezelo lwevidiyo ekumgangatho ophezulu kunye neesayizi ezincinci zeefayile. Ihlala isetyenziselwa ukuhanjiswa kwevidiyo kwi-intanethi.

Image

Iifayile zemifanekiso, ezifana neJPG, PNG, kunye neGIF, zigcina ulwazi olubonakalayo. Ezi fayile zingaqulatha iifoto, imizobo, okanye imifanekiso. Imifanekiso isetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanya uyilo lwewebhu, imidiya yedijithali, kunye nemifanekiso yamaxwebhu, ukuhambisa umxholo obonakalayo.
