FLV Tuhinga o mua Image Ngā Pātai Auau mō te Tahuritanga

He pēhea te tango i ngā tāruatanga mai i tētahi FLV video hei Image whakaahua?

Whakataki i te FLV ā, ka whakaaturia e te kaiwhakarere tētahi kōwhiringa rārangi-whakahauhau: ia rārangi Nth, ngā rārangi i ngā wā tauwhāiti, tētahi rārangi rānei i ia wa. Ka whakawaeheretia ia rārangi i kōwhiria hei pūranga takitahi Image, ā, ka whakawhāititia te tautuhi katoa ki roto i tētahi pūranga ZIP hei whakataki. Ko te FLV te pūrere Video Flash nāna i mau te katoa o ngā ataata tīwae mai i te tau kotahi mano e 2003 tae noa ki te mutunga o te tau 2020. 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 FLV, nā te mea kāore he rerenga tuhituhi kōwhiria e whakarerekē ana. Ko ngā mea katoa e whakaaturia ana e te FLV 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 ataata, ka whakawāteatia mai i tētahi pūtake i pupuri i te rua i te wāhanga, ā, ka tīari te tāruatanga. Kāore he kaituhi, he pūkoro, he pouaka whakaata rānei e taea te whakatangi i te FLV - me neke atu ētahi mea i roto i tēnei kāwai kia noho ai te mātakina.

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, nō 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 te whakamātautau anō, ā, ko te salahi 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 pēhea te whakamāramatanga o ia tātai i tāruatia Image e puta mai ana?

Ka taea e au te whakawātea i ia whārangi kotahi mai i te FLV hei Image?

Heoi, engari me āta whakaaro ki te tatau i te pūkete - he 30fps 1-roketi FLV e whakaputa ana i ngā tāruatanga 1,800 Image. Ka whakatū i a tātau i roto i tētahi ZIP. Mō ngā tāruatanga roa ake, ko te "1 i ia wa" kōwhiringa (60 rārangi), ngā rārangi wā rānei e hoatu ana i tētahi hua whakahaere.

Ka pupuri te Image whakaahua i te rangi o te FLV?

He — ka whakakōkītia te tae me te poukapa e whakamahia ana e te pūtake FLV (BT.709 mō HD, BT.2020 mō 4K HDR). Ko ngā pūtake HDR he tono-mātata ki SDR i te whakawāteatanga ki Image nā te mea ko te nuinga o ngā āhua Image (PNG, JPG) kāore e taea te rokiroki i ngā awhe pikitia HDR māori.

E pupuri ana te Image i te metadata o te kāmera EXIF?

Kāore te FLV kāwai e rokiroki i te EXIF-per-frame i te tikanga o tētahi pūwhitiwhiti, nā reira ka puta mai te Image me te EXIF mokowā. Ka whakawātea e tātau i tētahi āpure 'creation_time' e tohu ana ki te rārangi pūtake o te rārangi wā kia taea ai e koe te whakarōpū anō i te pūhui mā te raupapa tātari.

He maha te wā e mau ai te whakawāteatanga rārangi mai i te FLV ki te Image?

He tere te tango i te tāruatanga rārangi - i te nuinga o te 20 ki te 30% o te roanga pūtake i runga i te pūtautau paerewa. Ko te 5-meneti FLV → Image ka oti i roto i te minu i te nuinga o te minu, ahakoa te tautuhi rārangi, nā te mea ko te whākōkī te Image, ehara i te FLV demuxer.

Ka taea e au te whakawātea i ngā tātai i ngā wā tauwhāiti i roto i te FLV?

He — ka whakaaetia e te kōwhiringa mātauranga tētahi rārangi wā-whakahaeretanga o ngā tātai wā (hei tauira, `00:01:23,00:05:00,00:10:42`) ā, ka whakaputa i tētahi Image pūranga i ia wā. He whai hua mō ngā tātai whakahuahua o te wāhanga, ngā tātai tohutoro āhua, ngā whakaakoranga roa rānei.

He tūmataiti te āhua o te FLV o te poutū i te wā o te whakawāteatanga whārangi?

He — te tauira anō o te āhua o te āhua o te āhua o ia tahuritanga. Ko te ataata pūtake me ngā tāruatanga Image e mahia ana i roto i ngā kaimahi motuhake, ā, ka whakakoretia i roto i ngā minu; kāore he arotakenga tangata, kāore he whakaakoranga, kāore he uru ki te tuatoru.
