WMV → TIFF

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 TIFF 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.

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 TIFF i muri ake, kāore i te huri i te āhua. E whakahaeretia ana e TIFF a CMYK, te hōhonutanga 16-biti, ngā tātai ICC whakawātea me ngā tuhinga pāpāho maha, ko te mea tika e hiahiatia ana e te tātuhi me ngā rerenga mahi pūranga.

He nui ake i te mea e tūmanako ana koe, nā te mea ka pupuri te TIFF 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. He nui ake te TIFF i te pūrere: ka taea e ia te pupuri i te raraunga kāore i te whakawhāititia, LZW, ZIP, JPEG rānei, tae atu ki te 32-bitia rōpū, me ngā pātaka maha i roto i tētahi pūranga.

Ko te rongoā ōrite ki te pūtake WMV: he 1080p WMV e whakaputa ana i ngā tāpare 1920x1080 TIFF, he 4K WMV e whakaputa ana i ngā tāpare 3840x2160 TIFF. 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 TIFF. 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 TIFF 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 TIFF 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 TIFF: 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 TIFF 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 -> TIFF ka oti i roto i te 1 min ahakoa te maha o ngā tāpare e kōwhiri ana, nā te mea ko te kōwae te TIFF 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 TIFF 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.
