3GP Tuhinga o mua Image Ngā Pātai Auau mō te Tahuritanga

He pēhea te tango i ngā whārangi takitahi mai i te 3GP hei Image whakaahua?

Whakataki i te 3GP me te whakarerekētanga e whakaatu ana i tētahi kōwhiringa rārangi-whakahaere: ia rārangi Nth, ngā rārangi i ngā wā tauwhāiti, tētahi rārangi rānei i ia wa. Ka whakawāteatia ia rārangi i te rererangi vitio 3GP, ka whakawaeheretia hei Image tārua, ā, ka whakatōpūtia hei ZIP hei whakataki. Ko te 3GP te taiwhanga i whakaritea e te 3GPP mō ngā pūrere pāpāho o mua, i te wā e tika ana kia ōrite te ataata ki tētahi mata 176x144 me tētahi mahere raraunga 2G. Ko te whakaahua i konei he whāinga ahuwhānui: ka kōwhiria e te kaiwhakarere tētahi āhua raster mō te pūtake, kaua e whakahaua tētahi ki a koe.

Ka taea e au te whiwhi i ngā tātuhi Image me te kore ngā tuhipānui?

Ahakoa rā, kāore anō kia whakamātauria e te 3GP, nā te mea kāore he rerenga tuhituhi kōwhiria e whakarerekē ana. Ko ngā mea katoa e whakaaturia ana e te 3GP i runga i te mata i roto i te whakaahua, nō reira i ia Image ka puta te whakawāteatanga, ā, kāore he whakaritenga e tangohia ana i muri mai. Ki te tīariari he pūtake whakawātea o te tuhituhi whakawātea i te taha o te pouaka whakaata, ka tangohia mai i tētahi pūtake i pupuri i te rua i te wāhanga, ā, ka tīari te rārangi. E whakawhāititia ana te 3GP ki ngā rongoā iti me te oro-whakahaere-whakahaere; kāore e whakaora ana i ngā taipitopito kāore anō kia whiwhi.

E tautoko ana te huaputa Image i te mārama?

Ko te āhua o te āhua, engari kāore he pūtake ā-arawhiti hei hoatu ki a ia — he tino mārama ngā tāruatanga ataata me ngā pātaka i whakawāteatia e te āhua, nā reira ka tae mai ia pikitia ki te mārō. He tino whai hua tonu te kanikani ā-arawhiti i muri mai: ko te tikanga ka taea e koe te whakaiti i tētahi kaupapa mai i te Image i muri ake, kāore i te huri i te āhua. Ko te kōwhiringa o te ūnga ko te tikanga kia whiwhi rātau ki tētahi pūranga e whakatuwheratia ana i tētahi wāhi, kāore e hiahiatia kia whakaarotia tuatahitia ngā pūrere.

He nui rawa te Image o nga faila?

He nui ake i te mea e tūmanako ana koe, nā te mea ka pupuri te Image i ia pikitia kia tika, kaua e tata. Ko te 1080p e noho tonu ana i te 2-5 MB, ā, ko te 4K e noho tonu ana i te 6-15 MB, nā reira ka tere te tāpiri i te whakawāteatanga roa. Ko te hokohoko tika tonu tēnei ina kai te whakaahua i te whakamātautau anō, ā, ko te mea hē ina haere hāngai ki tētahi pou tītaka. Ko ngā pūtake whakaahua e whakawhirinaki ana ki te JPG, ko ngā pūtake me te mārama, me ngā pito mārō rānei e whakawhirinaki ana ki te PNG, ā, ko ngā pūtake maha-pāpāho e whakaputa ana i tētahi whakaahua i ia pāpāho.

I te rongoā pēhea e puta mai ai ngā whakaahua i tangohia Image?

Ko te rongoā ōrite ki te pūtake 3GP: he 1080p 3GP e whakaputa ana i ngā tāpare 1920x1080 Image, he 4K 3GP e whakaputa ana i ngā tāpare 3840x2160 Image. Kāore te tahuri i te whakapiki, i te whakaiti rānei i te whakapiki - ka tangohia ngā ahu pikitia mai i te tāpare kua whakawaengatia. Ka whakamahia /resize-image/ i muri i te whakataki mēnā e hiahiatia ana e koe ngā whakaahua iti iho.

Ka taea e au te whakawātea i ia tāpare o te 3GP hei Image?

Heoi, engari mā te whakaaro i te tatautanga o te faila — 30 fps 1-rohe 3GP e whakaputa ana i ngā tāruatanga 1,800 Image. Mātou e whakatū i a rātou ki roto i tētahi pūranga ZIP kotahi. Mō ngā tāruatanga roa ake, e manakohia ana te "1 i ia wa" (60 tāruatanga i ia wa), ka kōwhiri rānei i ngā tāruatanga wā. He wā o 3GP i ia tāruatanga ka puta mai ~100,000 Image ngā whakaahua.

He — ka whakakōkītia te tae me te poukapa ōrite e whakapuakina ana te pūtake o te pūtake 3GP (BT.709 mō te HD, BT.2020 mō te 4K HDR). Ko ngā pūtake HDR he tohu-whakatika ki te SDR ina tangohia ki tētahi Image kāore e taea te penapena i ngā awhe pikitia HDR māori (JPG, PNG-8). E ūngatia ana te PNG-16, TIFF rānei mēnā e hiahiatia ana e koe te pupuri i te awhe hihiri whakawhānui.

He nui te whāriki i tangohia Image i runga i te pūrere?

E ai ki te rongoā me te kōwhiringa pūkōrero Image: he 2-5 MB te whakapeka o te tāruatanga 1080p PNG, he 1080p JPG i te āhuatanga 85, he 200-500 KB. Ka whakarea e te tatau rārangi ki te rahi o te ZIP — i te tino, ko ia tāruatanga PNG rārangi o te 10-rohe 1080p 3GP e tata ana ki te 50 GB, ā, ka wehea ki ngā ZIPs maha.

E pupuri ana te Image whakawātea i ngā raraunga meta EXIF o te kāmera?

Kāore he 3GP tāwai e mau ana i te EXIF-per-frame i te āhua e mahi ai tētahi kāmera ā-ariā, nā reira ka puta mai ngā Image pūranga me ngā kōwae EXIF wātea. Ka whakatū te whakarerekē i tētahi āpure `creation_time` e tohu ana ki te rārangi pūtake o te wā, kia taea ai e koe te whakarōpū anō i te pūnaha i roto i te raupapa wāhanga, ki ngā tohu whakarārangi / wāhanga rānei.

He maha te wā e hiahiatia ana te whakawāteatanga rārangi mai i te 3GP ki te Image?

He tere te whakarerekētanga o te tāpare - i te nuinga o te 20-30% o te roanga pūtake. Ko te 5-meneti 3GP -> Image ka oti i roto i te 1 min ahakoa te maha o ngā tāpare e kōwhiri ana, nā te mea ko te kōwae te Image encoder e tuhi ana i ngā pūkete iti rawa i te taha kotahi, ehara i te 3GP demuxer.

Ka taea e au te whakawātea i ngā tāpare i ngā wā tika i roto i te 3GP video?

He — ka whakaaetia e te kōwhiringa wā whakahau tētahi rārangi kāpae-whakahaere (hei tauira, `00:01:23, 00:05:00, 00:10:42.5`) ā, ka whakaputa i tētahi Image pūranga i ia wā. Ka whai hua mō ngā tātuhi kōwae, ngā tātuhi tohutoro āhua, te hanga rānei i tētahi pepa hoapā mō te arotakenga.

He tūmataiti ahau 3GP i te wā o te whakawāteatanga whāriki?

He — te tauira anō o te ātetetanga pēnei i ia tahuritanga. Ko te pūtake 3GP me te pūtautau Image kua whakamātauria i roto i ngā kaimahi motuhake, ā, ka tangohia i roto i ngā minu o te whakaotitanga.
