WMV → BMP

Nā te mea kua whakawhāiti te pūtake. WMV Ko ngā ihirangi mai i te wā o te whakataka me te DVD e pupuri ana i ngā āpure haurua-whakahaurua e rua i ia tāruatanga, i whakawāteatia i te rima tekau o te tuarua, ā, ka whakawāteatia tonu te whakaaturanga e rua i te whakawhāiti i te āhua o te whakawhāiti i tētahi mea i neke mai. Mā te whakahohe i mua i te whakawāteatanga, ā, ka hangaia ia āpure mai i tētahi tāruatanga whakawhāiti kotahi.

Ahakoa rā, kāore anō kia whakamātauria e te WMV, nā te mea kāore he rerenga tuhituhi kōwhiria e whakarerekē ana. Ko ngā mea katoa e whakaaturia ana e te WMV i runga i te mata i roto i te whakaahua, nō reira i ia BMP 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. He tino tūkino te WMV: e hiahiatia ana e macOS, iOS, Android me ia kaiwhaiwhai ngā whakakōrero tuatoru, ā, ko ētahi pūranga WMV e mau ana i te DRM kāore e taea te tahuri.

He nui ake i te mea e tūmanako ana koe, nā te mea ka pupuri te BMP 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 te tikanga kia rokirokitia e BMP i ngā rārangi pikitia kore e whakawhāititia ana me tētahi pūwhakahako iti, nā reira he ngāwari noa iho te tātari.

Ko te rongoā ōrite ki te pūtake WMV: he 1080p WMV e whakaputa ana i ngā tāpare 1920x1080 BMP, he 4K WMV e whakaputa ana i ngā tāpare 3840x2160 BMP. 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.

Heoi, engari mā te whakaaro i te tatautanga o te faila — 30 fps 1-rohe WMV e whakaputa ana i ngā tāruatanga 1,800 BMP. 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 WMV i ia tāruatanga ka puta mai ~100,000 BMP ngā whakaahua.

He — ka whakakōkītia te tae me te poukapa ōrite e whakapuakina ana te pūtake o te pūtake WMV (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 BMP 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.

E ai ki te rongoā me te kōwhiringa pūkōrero BMP: 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 WMV e tata ana ki te 50 GB, ā, ka wehea ki ngā ZIPs maha.

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

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