1Whakarewa i tōna JPEG images ki roto i te kāwai i runga ake nei, ka tīpako rānei i a rātou mai i tōna pūrere — kāore he mea hei whakatū, kāore he pūkete hei waihanga.
2Ka kōwhiria te uaua ki te whakatūtū: he hua, he whāinga bitrate rānei, ā, ka taea te iti iho ngā ahu mēnā he nui ake te rahi i te taipitopito.
3Ka tīmata te mahi, ā, ka whakaaetia e ngā kaimahi te whakatū i te pūrere; kāore i te whakarerekētia tōmu taketake i te wāhi.
4E whakataurite ana i te rahi hou ki te taketake, kātahi ka whakataki te pūkete whakawhāiti JPEG.
Ka whakawhāiti JPEG Ngā Pātai Auau
He aha te whiwhingau ki te hokinga, ā, ka taea e au te whakahaere i te whakawhitinga?
+
Ko tētahi anake ngā pūkete whakawhāitia tāuru, i tētahi āhuatanga, i tētahi taumata bitrate rānei e kōwhiritia ana e koe, kaua ko tētahi pūmau tūturu. Mēnā kāore te hua i te iti rawa, ka huri i ngā ahu, i te roanga rānei, ka nui ake te mahi i te whakatū i te kāwai āhua.
He iti ake te rahi o te tāruatanga o te tāruatanga o te tāruatanga?
+
Ko te take e whakatauria ana e te ihirangi, ehara i te utauta. Ko ngā taipitopito whakaahua me ngā kākano kiriata e ātete ana i te whakawhāiti; he tae matatini, he tuhipānui me te whakawhāititanga. Ko te tūmanako tūturu he whakaiti nui i tētahi mea me ngā rohe ōrite nui, ā, he iti noa iho i tētahi whakaahua matatini, i tētahi tākaro nekehanga rānei.
Ka huri te āhua o tōku pūrangapū i te nui o te āhua o te pūrangapū ka taea e au te tiaki?
+
He tino nui rawa. He ōrite te JPEG ki te pūkōrero pēnei i te JPG i raro i tētahi whakaroanga roa ake - ōrite te pūtautau DCT, ōrite ngā ripanga whakarārangitanga, kāore he mea e huri ana i ngā pikitia me te ingoa faila. Ka whakataua e tēnei te mokowā o te hau e wātea ana, ā, mēnā ka utu te taumahatanga ki a koe he mea i roto i te pono.
Tērā tētahi mea motuhake ki te JPEG me mōhio au i mua i te whakawhāiti?
+
He — Ko te.jpeg me te.jpg ngā whakaroatanga he ōrite te rerenga ira, nō reira kāore he mea rerekē i tēnei i te.jpg — ka huri anake te ingoa o te pūranga. He tino mōhio i mua i te tuhituhi i tētahi taketake e hiahiatia ana e koe.
Ka whakaiti te Ka whakawhāiti JPEG i te āhuatanga o tōku JPEG images?
+
Ko te pūtake ngaro te hua o tētahi whakawhitinga whakawhāiti, ā, ko tētahi mahi me tāpiri anō i tētahi tuarua. Ki te taea te mahi i te mahi me te kore e pā ki te raraunga pikitia ka mahi tātau i taua mea, ā, i te kore e taea e koe te kōwhiri i te take āhuatanga mārō kia kore ai e whiwhi i tētahi pūtake pūmau.
Ka taea e au te whakahaere Ka whakawhāiti JPEG i runga i ētahi JPEG images i te wā kotahi?
+
He. Ka whakarewa te tautuhi katoa ki roto i te rohe whakarewa, ā, ka whakatū i te whakarerekētanga me ngā whakaritenga ōrite — ko te take matua kia mahia tēnei i roto i tētahi kaitiaki, kaua i tētahi faila i tētahi wā i roto i tētahi kaiwhakawhanake. Ko ngā pūkete wātea e whakahaere ana i tētahi faila i ia rōpū; Ka whakarewatia e te whakawhitinga.
He aha e pā ana ki te EXIF me te raraunga tātai tae?
+
Ko te EXIF o te pūrere (ISO, shutter, lens, GPS) me te tātai ICC whakawaitara e mau ana i te pūtake, nā te mea ko te whakawātea i te tātai e whakarerekē ana i ngā tae i te tāutanga anō. Ka whakamahia te kōwhiringa whaiaro hei whakawātea i te metadata i mua i te whakataki mēnā e whakapuakina ana e koe te pūkete.
He aha te utu o Ka whakawhāiti JPEG?
+
Ko te No. Ka whakawhāiti JPEG e wātea ana me te kore kāwai, kāore he tohu wai i te huaputa, ā, kāore he pakitara whakaingoatanga i mua i te whakataki. Ka tangohia ngā tāurunga i te wā poto i muri i te mutunga o te mahi.
He aha te mea e noho ana te WebM pae ki te Ka whakawhāiti JPEG?
+
E hangaia ana te WEBM.to i te taha o te kāwai i kōwhiria e te Wīwī tūwhera — VP9, AV1 rānei me te oro Opus, e whakakōrerotia ana e ia kaitiaki o nāianei, ā, kāore e hiahiatia he tāpiri, tārewa, kaiwhakaari rānei. Video is the case where extra round trips hurt most — the files are large and every upload costs real minutes. Running Ka whakawhāiti JPEG on the same pipeline as the conversions means one upload covers the whole job instead of one upload per tool.
He aha te mea me mahi au ki te hua ina oti te Ka whakawhāiti JPEG?
+
Ko te kaiwhakarere i tēnei pae e neke ana i te ataata i waenganui i te WebM, MP4, MKV, MOV me ētahi atu, ka tangohia rānei te pūoro katoa, me te kore e tāruatia tētahi atu. He nui ake te whai i te whakatūtū i taua āhuatanga mō te ataata i ētahi atu wāhi: ko ia tāurunga anō he whakatipuranga anō, nō reira he iti iho te āhua o te pūtake me te pūranga e whakaputaina ana e koe, he pai ake te āhua.
He Ka whakawhāiti JPEG tēnei te utauta ōrite e whakahaeretia ana e ngā pae hoa?
+
E tiritiri ana ngā mīhini — te hanga ffmpeg ōrite me x264, x265 me libvpx, ngā kaimahi ōrite, ngā tepe ōrite. Ko te mea e tāpiri ana tētahi pae WebM he tirohanga ki ngā kāwai me ngā pūrere: he pēhea ngā pahekotanga e tākaro ana i ngā wāhi katoa, e hiahiatia ana he tāurunga anō, ā, ka taea te tārua noa. Ka tīmata hoki i tētahi āhuatanga mō te āhua o tēnei pae i whakaingoatia i muri i: Ko te WebM he VP9, he AV1 rānei me te oro Opus, e whakakōrerotia ana e ngā kaiwhaiwhai i te āhua taketake engari ko te nuinga o ngā kaituhi papamaha e whakakōrerotia ana i te whakawhāititanga.
E hiahiatia ana e au he pūkete, ā, ka pupuritia ētahi mea?
+
Kāore he pūkete, ā, kāore e tiakina te video i whakawāteatia mai i ngā kaimahi i muri i te mutunga o te mahi, kāore e kitea, kāore e whakarārangitia. E tīari ana ngā pūkete wātea mō te hītori me te rahi o te rōpū, kāore i te āhei ki te uru ki.
