M4V Ngā Pātai Auau mō te Tahuritanga
He aha te M4V?
+
M4V is an MPEG-4 video container format, similar to MP4 but may include DRM.
He ōrite te pūranga M4V ki te MP4 i raro nei?
+
Ko te āhua o te hanganga he whanaunga tata rātau. M4V i hangaia mai i te tautuhi papatū ISO Base Media File Format e whakamahia ana e MP4 - he rākau ngota e pupuri ana i te raraunga pāpāho me tētahi taupū e kī ana i te wāhi e tīmata ana ia tāruatanga. Ko te take o te tahuri i waenganui i a rātou he whakarerekētanga i te nuinga o te wā, kaua he tāruatanga anō: ka tāruatia ngā aho i te wāhanga, ā, ka tāruatia anō anake te wrapper, e roa ana ngā wā i runga i tētahi pūkete āhuatanga roa. Ko te M4V he tāupe Apple o MP4, e whakamahia ana e iTunes me te Apple TV app mō ngā whitiāhua me ngā wāhanga TV.
He aha te take i tae ai ngā hokonga hei M4V?
+
Nā te mea ko te āhua o te whare mātauranga te whāriki whakawhiwhinga, e hono ana ki ōna taupānga, ā, mō ngā ihirangi i whakawhiwhia, ki tōna kāwanatanga. Ko te mea e āhei ai i roto i taua pūnaha āhua me te āhua o waho. Ko ngā pūranga kāore i te kōkuhu-kōkī, ka huri noa; Kāore e taea te whakatuwheratia e ētahi kaiwhakarere, he āhuatanga tūturu o te āhua, ehara i te whakawhāiti i tēnei wāhi.
He aha te take kāore e whakatangitangi te mātāwai i tētahi M4V?
+
Ko ngā kaiwhaiwhai e whakarewa ana i ngā whakakōrero mō tētahi rārangi poto o ngā āhuahira, ā, kāore te M4V i runga i te — te āhuahira, te momo codec e whakaaetia ana, e noho tonu ana tōna pakeke. Kāore te faila i te whakaroa, ā, ka whakatuwheratia e te kaiwhakaari papamuri, engari kāore he mea e mahi ana koe ki te pātaka ka whakawātea e te kaiwhaiwhai. Ko te tahuri ki tētahi tahuri tīpaetia-tīwae te huarahi anake e tautoko ana i te whakateretanga. Kāore e taea te tahuri i ngā hokonga M4V i parea e DRM; ko ngā pūranga M4V kāore i parea anake e taea te tahuri, ā, ko ngā kaiwhakaari kāore i te Apple e hiahiatia ana te whakaroanga.
Ka whakapāpāho te M4V ki runga i tētahi pūkoro, TV rānei me te kore e whakawātea i te pūkoro?
+
I te nuinga o te wā, ā, nā te mea ko ngā pūrere i roto i ngā tāuru, ngā tātari me ngā pouaka whakaata e whakawaehere ana i tēnei momo utu i roto i ngā pūrere kua whakaritea, kaua i te pūnaha matua. Ko te rerekētanga i waenganui i tētahi ataata e whakaata ana i te rua wā me tētahi e whakamārō ana i te pūrere, ā, ka whakawātea i roto i te whā tekau minu. I te wāhi e whakapeka ana te āhua, he tautoko papatono, ehara i te whakawaeheretanga — he pai te pūrere, ko te whāriki te mea e whakakāhore ana te papatono whare whakataki. Ko te hanganga o te M4V he MP4 — H.264, HEVC rānei me AAC — me te Apple FairPlay DRM kōwhiria me te iTunes wāhanga metadata.
E whakawāteatia ana te M4V?
+
Kāore e ngaro i te wā kotahi, engari ko tōna wāhanga o ngā pūranga hōu e whakaiti ana, ā, he iti iho ngā utauta hōu e whakamātau ana ki te tautoko i a ia. Ka noho ngā pūranga tīariari e taea te whakaako i te wā roa. Ko te tūnga ā-tinana ko te pupuri i tētahi pūranga i tēnei āhua, he pai, i te tīmata i tētahi rerenga mahi hou i roto i te tikanga o te whakaae ki tētahi huinga pūmanawa ā-whāiti ake.
He whakahuahua i roto i tētahi M4V, ka whakamātauria rānei ki roto i te whakaahua?
+
Ka taea te kōwhiri, mēnā i tāpiri tikatia rātau. M4V e mau ana i ngā whakarārangi hei ā rātou ake rerenga i te taha o te ataata, kia taea ai e te kaitirotiro te whakawhiti reo, te whakakore i a rātau, te whakarerekē rānei i a rātau i roto i tētahi pūpāpāho e tautoko ana i a rātau. Ka taea hoki ngā whakarārangi whakamārō - he pikitia anake i roto i te tāpare - engari he mau tonu, ā, kāore he take hei kōwhiri i a rātau ina tautokona e te kāwai te mea tūturu.
Ka taea e tētahi M4V te pupuri i ētahi rererangi oro?
+
He — ka taea e tētahi whākōkī reo taketake, he tāruatanga me tētahi kōrero te noho katoa i roto i te pūrākau ōrite me te kaipāpāho e whakawhiti ana i waenganui i a rātou. E rua ngā mōrearea: he maha ngā pūpāho tāruatanga me te pouaka whakaata e whakaatu ana i te pūrākau tuatahi anake, ahakoa he maha ngā mea e tīari ana, ā, ko te tahuritanga ki tētahi āhuahanga kāore i te tautoko i te pūrākau maha tūturu e pupuri ana i tētahi pūrākau me te whakawātea i te toenga. Hiko te pūrākau e hiahiatia ana e koe i mua i te tahuritanga, kaua e kitea i muri iho he mea ora tētahi. E pupuri ana a M4V i ngā tohu wāhanga, i ngā mahi toi me ngā whakataki whakahuatuhi i roto i te āhua e tūmanako ana te Apple TV ki te taupānga, e ngaro ana i te nuinga o te wā te MP4 noa iho.
Me hiahiatia anei e au he Mac hei mahi ki ngā pūranga M4V?
+
Kāore. I puta mai te āhua o Apple, ā, ko ōna pūrere me ngā pūmanawa e whakaputa ana i te pūmau, engari he pūnoa ngā pūranga anō, ā, ka pānui ki ētahi atu wāhi me te utauta tika. Ka puta te tahuri i tēnei wāhi i runga i te pūnaha, nā reira kāore he whakatū QuickTime, kāore he pūrere Apple, ā, kāore he paki codec pūwāhi-whāiti i roto i te tukanga.
E pupuri ana te M4V i ngā tohu wāhanga?
+
He mea — e noho ana ngā wāhanga i roto i ngā metadata kāwai, nā reira ka taea te whakatere i tētahi pūkete roa e te wāhanga i te wāhi i te wā e whakarewa ana i tētahi pae nekeneke. Ka ora rātau i tētahi whakarerekētanga ki tētahi atu āhua, ā, ka whakawāteatia, he mārō, e tētahi kāore he wāhi hei whakatakoto i a rātou. Mēnā he mea hira ngā wāhanga, he tino tika te arotake i mua i te kōwhiringa o te āhua huaputa, kaua i muri iho.
E hiahiatia ana e te M4V he whakaaetanga whakawhiwhinga?
+
Kāore mō koe. Ko ngā pūkōrero e pā ana ki ngā pūtake ā-whakahaere, ā, ka whakaritea te whakaaetanga e ngā tāngata e whakarewa ana i ngā whakarerekētanga — te pūkoro, te whakataki, te pūnaha whakahaere — i mua i te tae atu o tētahi pūkōrero ki a koe. Ko te take o te āhua i ngā wāhi katoa o ngā pūrere, ko te take o te tīariari-kore-kore, ā, kāore e huri i te tahuritanga o tētahi pūkōrero kua whiwhi ki a koe.
Ka taea e au te whakahōu te whakaroa i te wāhi i te whakarerekētanga o M4V?
+
Tata tonu ki te kore, ā, e mōhio ana te take: he tohu te whakaroatanga, i te wā e hanga ana ngā paerewa i roto mō tētahi hanga tauwhāiti. Ka whakaputaina e te whakahōutanga he faila ko te ingoa e whakapuakina ana he mea kāore i te tuku i ōna ihirangi, ā, ko te mea e whakatuwheratia ai, ka whakakāhore rānei i te faila, ka pāpāho rānei. Ko te whakawāteatanga whāiti kotahi ko ngā hanga e rua e tino ōrite ana i raro i ngā ingoa rerekē — ā, ahakoa he haumaru ake te whakaroanga tika i te whakahōutanga.
