M4V → WMV

Kāore e taea te tīpako, nā te mea kāore he pūwhitinga pūāhua-whakaahua mārō a WMV hei pupuri i a rātau. E rua ngā ara kia puta mai: ka whakamārō i a rātau ki roto i te ataata i te wā o te tahuritanga, e noho ai rātau ki te noho tonu, ki te kore āhua, ki te whakawātea rānei i a rātau hei.srt motuhake i te taha o te WMV mō te pūpāho hei whakarewa. E kī ana te kaiwhakarere ki a koe he aha i mahi ai, kaua e whakawātea i a rātau. 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.

Kāore i te āhua tika. M4V e rokiroki ana i ngā aho maha hei whakataki ā-ira tuatahi, engari he āhua kore tonu te WMV tautoko whakataki i muri i te whakataki tuatahi, nā reira ko te nuinga o ngā kaiwhakaari ka whakaaturia anake tētahi. Ka kōwhiria te whakataki e hiahiatia ana e koe i mua i te tahuri; He pai ake te whakawātea i ētahi atu ki o rātau ake pūkete i te waiho i roto i tētahi kāwai e whakawātea ana i a rātau. 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.

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, 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. WMV 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.

Nā te mea he maha ngā pūrere kāore i ako i tētahi mea hōu, kāore hoki ka āhei. Ko ngā kaiwhakaari DVD, ngā wae o te waka, ngā āhuatanga whakaterenga kāmera, ngā whakaaturanga mahi me te maha o ngā pūrere whakateretanga e whakaae ana ki WMV ā, kāore anō ētahi atu. Ko te tahuritanga he hipanga tūturu ki raro i te mātauranga, i hokona hei whakawhitinga mō te mahi i tētahi pūrere kāore he kōwhiringa anō. He pai te whakawhāititanga o te WMV mō tōna pakeke, ā, ka noho tonu te hanga PowerPoint, ngā pūkete mata Windows tahito me ngā pūranga pāpāho ka whakaritea.

He — ko ia whakataki oro i roto i te M4V (whakaaro a te kaiwhakahaere, reo whirinoa, oro whakaahua) ka tiakina ki te WMV ina tautokona e te pūrere te oro-maha. MKV me MOV e whakahaere ana i ngā whakataki oro kāore i te whakawātea; he maha ngā MP4 e tautoko ana, engari ko ētahi kaiwhakaari pūrere e kite ana i te whakataki 1 anake; Ka whakawāteatia te WebM i te whakataki Opus / Vorbis kotahi. Ko WMV te Windows Media Video, he hanga ā-ASF a Microsoft mai i te wā o Windows XP.

Ka ora ngā whakahuatuhi māmā (ngā rererangi ka tīpakohia) ina taea e WMV te mau i a rātou: MKV kei roto i te SRT, ASS, SSA, PGS, VobSub māori; MP4 kei roto anake i te mov_text (he hanga whakawātea). Ko te tahuritanga o tētahi MKV me ngā whakahuatuhi āhua ASS ki MP4 ka whakaiti i a rātou ki te mov_text, ka whakarewa rānei i a rātou. Ko ngā whakahuatuhi matatini (i whakarewatia ki roto i te ataata) ka mau i a rātou ahakoa pēhea.

Ka whakawhitia ngā raraunga meta i waenganui i te M4V me te WMV ina tautokona e ngā kāwai e rua tētahi ngota wāhanga (MKV, MP4, MOV). Ka penapena te WebM i ngā wāhanga i roto i tētahi kōpaka Matroska-hōpū, kia mārama ai ngā wāhanga MKV <-> WebM. Kāore he whakapūtā wāhanga a AVI, nā reira ka tahuri te tahuri AVI ki te WMV i tētahi pūranga kāore i te whakarārangi, engari rawa ka tāpiri i ngā tohu ā-ringa.

Ko MKV te mea anake e pupuri ana i ngā pūkete whakapiripiri (ngā tātuhi TTF mō ngā tātai ASS, ngā toi kāwai JPG, ngā tāurunga PDF i whakamāoritia). E haere ana mai i te M4V ki te WMV ka whakapeka ēnei tātai ina kore te WMV he MKV — ka tahuri ngā rerenga taketake, engari ka noho te utu whakapiripiri i te pūtake. Whakataki M4V hei tiaki i ētahi atu tātai mēnā e whakawhirinaki ana ki ngā tātai whakapiripiri.

E kōwhiritia ana te pūnaha waeheretanga pūnoa hei ōrite ki te WMV kaitakawaenga: MKV ngā pūnoa ki H.265 (HEVC) mō te whakawhāititanga pai ake; MP4 ngā pūnoa ki H.264 mō te tautoko pūrere whānui rawa; WebM ngā pūnoa ki VP9; AVI e whakamahi ana i te MPEG-4 ASP (DivX/Xvid lineage). Ka whakawātea mā te whakawātea codec hōhonu — Kei te wātea te AV1 mō MKV / WebM i reira e hiahiatia ana e koe te whakawhāititanga nui rawa, ā, ka taea te tūmanako mā te waehere.

Ko te metadata HDR takoto (HDR10 nga uara whakaaturanga matua, te taumata mārama ihirangi) e mau ana ki te WMV ina tautokona e ngā kāwai me te pūāhua kōaro i kōwhiria (HEVC, AV1 i MKV / MP4). He nui ake te pōturi o Dolby Vision — ko te tātai DV 5 / 7 / 8.1 i te M4V e ora noa ana ki te MKV me HEVC; te tahuri ki tētahi WMV kāwai kāore e mau ana i te apa DV ki te HDR10.
