Indlela yokucindezela JPEG

1 Nciphisa i JPEG images yakho kwibhokisi eliphezulu, noma ukhethe kusuka kwidivayisi yakho — akukho okuzofakwa futhi akukho i-akhawunti eyenza.

2 Khetha ukuthi kunzima kangakanani ukucindezela: umgangatho noma i-bitrate efanele, futhi ngokuzikhethela ubukhulu obuncane uma ubukhulu bubalulekile kuwe kunemingwane.

3 Qala umsebenzi bese uvumela abasebenzayo ukuthi baphinde bahlanganise ihele; okubhaliwe akushintshiwe endaweni.

4 Linganisa ubukhulu obusha nobukhona, bese ulanda ifayela elicindezelwe JPEG.

Cindezela JPEG Imibuzo Evame Ukubuzwa

Yini engitholayo emuva, futhi ngingakwazi ukuphatha i-trade-off?

Ihele elilodwa elicindezelwe ngengeniso ngalinye, kukhwalithi noma izinga le-bitrate okhetha kuyo kunephutha eliqinile. Uma imiphumela ingancane ngokwanele, ukuguqula izilinganiso noma isikhathi sizokwenza okuningi kunalokho ukucindezela isici sokuzingela ngezansi.

Ingabe ifayela lami lizobe lincane kangakanani?

Lokhu kucatshangelwa yizinto eziqukethwe, hhayi yithuluzi. Imingwane yesithombe kanye nefilimu ye-grain imelana nokucindezeleka; umbala oqinile, umbhalo kanye nokucindezeleka. Ukulindeleka okungokoqobo kuncane kakhulu kunoma yini enezindawo ezinkulu ezifanayo futhi kuncane kakhulu kusithombe esixakekile noma kuclip ehamba phambili.

Ingabe ifomu lefayela lami lishintsha inani engingagcina ngalo?

Kuhle kakhulu. I-JPEG iyi-codec efanayo ne-JPG ngaphansi kwesiqiniseko eside — i-DCT pipeline efana, amathebulethi okulinganisela afana, akukho okushintshayo nge-pixels ngegama lefayela. Okusho ukuthi igumbi lokuphumula elikhona kanye nokuthi ngabe ukulondoloza kubiza yini noma yini ethembekile.

Ingabe kukhona okuthile okukhethekile ku JPEG okufanele ngikwazi ngaphambi kokucindezela?

Yebo — i.jpeg ne.jpg izixhumanisi ziyi-bitstream efanayo, ngakho akukho okuthile lapha okuzosebenza ngokuhlukile ku-.jpg — igama lefayela kuphela elishintshayo. Kubalulekile ukwazi ngaphambi kokubhala ngaphezulu okujwayelekile okungahle kudinga ukuphinda.

Ingabe Cindezela JPEG izonciphisa ukhwalithi ye JPEG images yami?

Umsuka olahlekelwayo usuke umphumela wesikhathi sokungena esingu-1, futhi noma yisiphi isenzo esidinga ukuphinde sikhombise sifaka isithupha. lapho umsebenzi ungakwenziwa khona ngaphandle kokuchofoza i-pixel data sizokwenza lokho endaweni, futhi lapho kungasakwazi khona ukhetha i-quality factor wena ngokwakho ngaphezu kokuthola iphutha eliqinile.

Ingabe ngizosebenzisa Cindezela JPEG ku JPEG images amaningi ngasikhathi sinye?

Yebo. Thola isethulo esigcwele endaweni yokulayisha bese zihamba ngokufanayo nezilungiselelo ezifanayo - lokhu kuyisizathu esiyinhloko sokwenza lokhu kubrowser ngaphezu kwefayela elilodwa ngasikhathi sinye kumhleli. Ama-akhawunti amahhala aqhuba ifayela elilodwa ngasikhathi sinye; i-pass lifts that.

Yini ekwenzeke ku-EXIF nedatha yeprofayili yombala?

Ikhamera EXIF (ISO, i-shutter, i-lens, GPS) neprofayili efakwe ngaphakathi ye-ICC idluliselwa ngokuzenzakalela, ngoba ukushiya iprofayili kwenza umbala ushintshe uma ufaka kabusha. Sebenzisa ukhetho lokufihla ukususa i-metadata ngaphambi kokukhishwa uma uhlela ukushicilela ifayela.

Ingabe Cindezela JPEG ibiza noma yini?

No. Cindezela JPEG ikhululekile ngaphandle kwe-akhawunti, akukho uphawu lwamanzi ku-output futhi akukho mnyango wokubhalisa phambi kokulanda. Ukulayisha kususwa ngokuzenzakalela isikhathi esincane ngemuva komsebenzi ophelile.

Kungani i WebM site i host Cindezela JPEG?

WEBM.to ifakwe endaweni yebhokisi lewebhu evulekile ekhethiwe — VP9 noma AV1 ne-Opus audio, eqoshwe ngokusemthethweni nganoma iyiphi i-browser yamanje futhi edinga noma yikuphi ukufaka, ilayisense noma umdlali. Ividiyo iyisimo lapho izindiza ezijikelezayo ezingeziwe zibuhlungu kakhulu - amafayela akhulu futhi wonke ama-upload abiza amahora angempela. Ukusebenza Cindezela JPEG ku-pipeline efanayo njenge-conversions kusho ukuthi u-upload owodwa ufaka umsebenzi wonke endaweni yokufaka olunye olunye olunye olunye.

Yini okufanele ngiyenze ngemiphumela uma i Cindezela JPEG iqediwe?

Isiguquli kule webhusayithi sihamba ngevidiyo phakathi kweWebM, MP4, MKV, MOV neminye, noma sisusa umsindo wonke, ngaphandle kokufaka omunye. Ukulandelela ngendlela enjalo kubaluleke kakhulu kuvidiyo kunanoma kuphi: ngayinye iphinde ikhodwe yisigaba esisha, ngakho-ke uma kungekhona phakathi komthombo nefayela oshicilela, ibukeka ingcono.

Ingabe Cindezela JPEG lapha ithuluzi elifanayo lezindawo ezifanayo ezisebenza?

Ama-engine ahlukaniswe — i-ffmpeg efana ne-x264, x265 ne-libvpx, abasebenza nabo, ama-limits afanayo. Okushiwo yi-WebM site kubukeka ku-container ne-codec: ukuthi ukuhlanganisa kudlala kuphi, odinga uku-encode futhi ongakwazi ukukopela ngokulula. Kuqala futhi kusuka kuqiniso elinye mayelana nefomethi le site ibizwa ngemuva: WebM yi-VP9 noma AV1 ne-Opus audio, okungukuthi iziphequluli ziyi-decode ngokusemthethweni kodwa okungukuthi amanye ama-desktop editors agcina e-transcode uma kufakwa.

Ngidinga i-akhawunti, futhi yini egcinwa?

Akukho akhawunti, futhi akukho okugcinwa: ividiyo elayishwe phezulu isuswa abasebenzayo ngemuva komsebenzi oqediwe, akukho okuboniswe futhi akukho okuhlobene. Ama-akhawunti amahhala akhona ngembali nenani leqembu, hhayi ukufinyelela.
