M4V → MKV

Tata tonu ki te DRM i ngā wā katoa. Ko ētahi M4V ngā pūranga e whakawaeheretia ana i te taumata bitstream e te puna, i te pūmanawa rānei i tukuna ai rātou, ā, kāore e taea te whakawaehere i tētahi rerenga whakawaeheretia e tātau, e tētahi atu rānei me te kore te kī ā-whakahaere. Ko ngā pūranga i whakahuatia e koe, i whakawātea, i whakawāteatia rānei i te whakarerekētanga kāore i te parea; kāore e taea e te hoko ā-whakahaere te whakawhiwhia, ā, kāore e taea e te kaiwhakarere te whakaū i tētahi atu mea. 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 whakaroa.

Tērā pea kāore. M4V e whakakōrerotia ana e te pūkoro whakatapua i runga i ngā pūkoro, ngā tāpapa me ngā TV, nā reira ka tākaro i te pūrere me te kore whakawātea i te pūkoro. MKV i te nuinga o te wā ka hoki ki te whakakōrero pūmanawa i runga i te pūrere ōrite — te utu CPU tiketike ake, he pūrere wera, me ngā tāruatanga i runga i ngā rauemi 4K. Mō tētahi whāinga pūrere, M4V ko te pūrere haumaru ake hei noho i roto. Tata tonu ki te kore e tautokona e MKV ngā pūrere māori — ko ngā pūrongo, ngā kaituhi me ngā pouaka whakaata e hiahiatia ana e VLC, he remux rānei i mua i te whakataetae.

E pupuri ana i ngā ōritetanga i reira ka haere te faila, nā te mea kāore e pai ake i te whakarārangi. Ko tētahi o ēnei e rua e hangaia ana mō te ōritetanga whakatere, ā, ko tētahi atu mō te pupuri i ngā mea katoa ka taea e tētahi pūranga te pupuri, ā, ka whakawhitiwhiti rātou ki a rātou anō i runga i taua raina. Ko te whakautu ā-pūnaha mō te nuinga o ngā puna ko te pūranga i roto i te pūrere āhuahira-tōtika me te whakawātea ki te ōrite i te tono. 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. Ko MKV te pūranga kōwhiringa o te kōwhiringa nā te mea ka pupuri i ngā aho whakatere, ngā whakahua whakahua, ngā tohu wāhanga me ngā toi kāwai i roto i tētahi pūranga kotahi.

E ai ki te MKV. MP4 te pūnaha ki H.264 mō te tautoko pānui whānui rawa puta noa i ngā pūkoro, ngā kiriata, me ngā Smart TV. MKV te pūnaha ki H.265 / HEVC mō te haurua o te rahi o te faila i te āhuatanga ōrite. Ko te pūnaha WebM ki VP9. Ko ngā kōwhiringa tiketike e whakawātea ana i te kōwhiringa pūnaha mēnā e hiahiatia ana e koe kia whakawātea. Ko MKV ko Matroska, he pūrere tūwhera i hangaia i te tau 2002 me te kore whakawhanake ā-whakahaere, ā, kāore he taumata ki te mea ka taea e ia te pupuri.

Inā M4V me MKV e tiritiri ana i tētahi pūkōrero oro (hei tauira, e mau ana rāua i te AAC), ka whakawāteatia anō te oro me te kore whakawaeheretanga anō - he ōrite te iti. Ki te rerekē ngā pūkōrero, ka whakawaeheretia te oro ki te AAC / Opus / Vorbis i runga anō i te mea e tautoko ana te MKV. Ka tiakina te oro-maha (whakaaro, reo whirinoa).

Mā te pūmau, ā, — he 24fps M4V e noho ana i te 24fps i roto i MKV; he 60fps M4V e noho ana i te 60fps. Mēnā e hiahiatia ana e koe kia huri i te mokatere (hei tauira, 29.97 → whakatere 30, 60 → 30 rānei mō ngā tepe whakataki), ka whakahaeretia e te kōwhiringa rārangi te 3:2 whakatere, te whakarerekētanga, me te whakakotahitanga rārangi i te whakawhitinga waehere ōrite.

He rite tonu te kōwae-kore-kore (M4V H.264 → MKV H.264 e huri ana i te kāwai): tata tonu ki te ōrite te rahi. Ka taea te huri i te kōwae: H.264 → H.265 i te nuinga o te wā e haurua ana te pūranga i te āhuatanga ā-whakaahua ōrite; He āhua ōrite tonu te VP9; AV1 e whakaiti ana i tētahi atu 20-30% engari he pōturi ake te waehere.

MP4 / H.264 e tākaro ana i ngā pūrere o nāianei. E tākaro ana te MOV / H.264 i ngā pūrere Apple me te nuinga o ngā TV engari kāore i te wā katoa i runga i te Android tawhito. E hiahiatia ana e MKV te VLC i runga i te iOS. Ko te WebM te kitenga tuatahi. Kei roto i ngā kōwhiringa tiketike he "whakapae pūrere" e kōwhiri ana i te MKV codec / waikawa tino haumaru mō tōtou ūnga.

He tata tonu te whakarerekētanga o te pūrere ōrite — 30 ki te 60 ngā takiwā mō tētahi pūranga 1-ora. Ka haere te whakarerekētanga pūrere katoa i te 0.3-0.7x te roanga pūtake i runga i tātau pūtau GPU, nō reira ka oti te 1-ora M4V → MKV i roto i ngā minu 18-40 i runga anō i te rongoā me te pūrere ūnga.

Tae atu ki te 8K (7680×4320) i runga i ngā mahere Premium. Ko ngā tahuritanga wātea e whakawhāititia ana ki te 4K (3840×2160) e te tepe o te rahi o te pūkete. Ko ngā metadata HDR (HDR10, HDR10+, Dolby Vision ina tīari) e mau ana i reira e tautoko ana e ngā kāwai M4V me MKV.

He. Ka tuwhera ngā faila ataata i whakarewaina ki roto i ngā kaimahi motuhake, kāore i kitea e te tangata, kāore i whakarārangitia, ā, ka tangohia i roto i ngā minu o te whakaotitanga. Kua tuhituhitia te matapihi tauwhāiti i te /privacy/ ā, kāore e whakaputaina e tātau he whakaakoranga o te pūnaha mai i ngā tāurunga o te kaimahi.
