MOV Tuhinga o mua PNG Ngā Pātai Auau mō te Tahuritanga

He pēhea te tango i ngā whārangi takitahi mai i te MOV hei PNG whakaahua?

Whakataki i te MOV 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 MOV, ka whakawaeheretia hei PNG tārua, ā, ka whakatōpūtia hei ZIP hei whakataki. Ko MOV te pūrere QuickTime a Apple, i tukuna i te tau kotahi mano e 1991, ā, ko te āhua tonu o te iPhone, iPad, Final Cut Pro rānei e tuhi ana i te rārangi wā mā te pūmau. I hangaia a PNG i te tau kotahi mano e 1996 hei whakakapi kore whakawhiwhinga ki te GIF, ā, ka noho hei hanga whakaahua pātata kore ngaro o te Wīwī.

Ka puta ake te whakataki i roto i ngā tātai PNG ka tāruatia?

Kāore mēnā he whakataki whakahuatuhi tūturu rātou. Ka pupuri te MOV i ngā whakahuatuhi hei a rātau ake rerenga, ā, ka tātuhia e te kaiwhakaari i runga i te whakaahua i te wā whakataetae, nō reira ko te tātai whakakōrero e tuhi ana i waho hei PNG he pikorata mārō i raro i te PNG. Ko ngā whakahuatuhi i whakamārōtia ki roto i te ataata i mua i te nohotanga o MOV he mea rerekē — i taua wā he wāhanga o te whakaahua, ā, ka pupuri i ia tātai whakawātea.

Ka taea e au te tango i tētahi PNG mai i ia wāhanga o te MOV?

Kāore i te pēhi te kī kotahi, engari ko te MOV e whakamāramatia ana: ka rokirokitia ngā tohu wā i roto i te kāwai hei tātaitai wā, nā reira ka whakaako te rārangi wā i te pūranga, ā, ka tāpiri i ēnei wā ki te āpure tātaitai wā. Ka whiwhi koe i tētahi PNG i ia wā, i te raupapa, ko te tikanga noa iho o te hanganga o ngā tātuhi mō tētahi pūkete roa. Ka waiho e ngā pūtake kāore i te tohu wā te kōwhiringa o ngā tirohanga mā te kanohi. Ko te MOV te āhua o ngā kaiwhakawhanake ngaio e hiahiatia ana, nā te mea e ora ana i ngā haerenga tukurua puta noa i te Final Cut Pro, Premiere me DaVinci Resolve me te kore ngaro i te whakatupuranga.

E tautoko ana te huaputa PNG 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 PNG i muri ake, kāore i te huri i te āhua. Ko PNG te kōwhiringa tika mō ngā whakaahua mata, ngā tohu, ngā toi raina me ētahi atu mea me ngā taitapa mārō, mārama rānei — kāore he whakawhāiti, kāore he tae.

He nui rawa te PNG o nga faila?

He nui ake i te mea e tūmanako ana koe, nā te mea ka pupuri te PNG 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. Ka whakamahia e PNG te whakawhāititanga DEFLATE i runga i ngā raina tātari tātari, kia ora ai ia pikitia, tae atu ki tētahi kanikani ā-arawhiti 8-biti.

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

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

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

Ka pupuri te PNG tāruatanga tae i te MOV?

He — ka whakakōkītia te tae me te poukapa ōrite e whakapuakina ana te pūtake o te pūtake MOV (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 PNG 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 PNG i runga i te pūrere?

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

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

Kāore he MOV 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 PNG 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 MOV ki te PNG?

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

Ka taea e au te whakawātea i ngā tāpare i ngā wā tika i roto i te MOV 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 PNG 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.

MOV

Ko te MOV te hōputu QuickTime a Apple, e tautoko ana i ngā ataata me ngā oro kounga teitei mō te whakatika ngaio.

PNG

Ka tautokohia e ngā kōnae PNG te māramatanga, ā, ka whakamahia te kōpeketanga kore-ngaro, he mea tino pai mō ngā whakairoiro, ngā waitohu, me ngā hopu mata.
