VOB → MP3

Heoi, ā, e tika ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ko te MP3 encoder e mahi ana mai i te oro, kua puta kētia e tētahi whakawhitinga psychoacoustic, ā, ko ōna whakataunga anō e whakakotahi ana i te tautuhi tuatahi. I te 192 kbps, i runga ake rānei i te hua, he mārama tonu te hua mō te nuinga o te whakarongo. Mēnā kei a koe tētahi māngai kore ngaro i tētahi wāhi, ka whakakōrerotia te MP3 mai i tērā, ka kore e taea te whakawhiti i te whakawhitinga rua katoa. Kei roto i te VOB te ataata MPEG-2, AC-3, PCM oro rānei, me ngā rerenga whakahuatuhi DVD, i wehea ki ngā wāhanga 1 GB e te DVD. He ngaro te MP3: ko te tauira ā-hinengaro e whakakore ana i ngā auautanga kāore e taea e te oro te mōhio, i te nuinga o te wā i te 128 ki te 320 kbps.

Heoi, ā, he whiwhinga tūturu i runga i te VOB, kāore he wāhi e whakawhirinaki ana ki te rokiroki i tētahi o ia. MP3 e mau ana i te taitara, te kaitapere, te pūrākau, te tau, te tau rererangi me te toi kāwai i roto i te kāwai anō, kia tika ai te pūranga pūoro me te kore e whakawhiti i te kāwai. Kāore he mea e whakawātea ana i te MP3 mō te ōritetanga — ko ngā pūrere waka, ngā pūrere ā-rohe, ngā DAP me ngā pūrere o te rua tekau tau e whakaako ana i a ia me te kore pātai.

Ka whakaroatia ki raro ki te stereo, nā te mea kāore he āhuatanga ā-maha o MP3. Ka whakamahia e te whakarōpūtanga ngā taupū paerewa kia mārama ai te whakawhitinga pūwāhi-pūwāhi, ā, ka whakarōpūtia ngā rohe i te taumata iti iho. Ka ngaro tētahi mea i runga i te tauwāhi pūwāhi motuhake ina puta mai. Ko te MP3 e whakawāteatia ana e te AAC me te Opus i ia mokatere tātai, kāore e taea te rokiroki i ngā kanikani nui ake i te rua, ā, ka tāpiri tonutia he whakamutu ā-waenga iti.

DRM. He pūrere ā-roto o ngā pūranga VOB kua whakawaeheretia e te puna, te pūmanawa rānei i tukuna, ā, kāore e taea te whakawaehere i te oro whakawaeheretia e tētahi kaiwhakarere. Ko ngā mea katoa i whakawāteatia e koe, i whakatata, i hoko rānei me te kore parenga, ka huri noa; kāore e hoko te hoko ā-kōrero. Ka wehea te VOB i waenganui i ngā pūranga, ka taea te whakawaehere i te CSS, ā, ka mau ngā pakiaka whakatere e whakamātau ana i ngā kaiwhakaari taketake.

Mā te pūngao pūmau 0 (te pūrere oro tuatahi, i te nuinga o te wā ko te whakakotahitanga matua). Mēnā ka mau te VOB i ngā kōrero, ngā tāruatanga, ngā pūoro whakaahua rānei i runga i ngā pūrere tāpiri, ka whakaaetia e te kōwhiri "pūngao oro" whakahauahua kia kōwhiria e koe te 1, 2, 3... mārama. Ka whakaaturia te rārangi rererangi i te tirohanga tāuru, nā reira kāore e kōwhiria e koe te matapōkere.

Ko te MP3 te mokatere bita tōtika tōtika ko te 192 kbps (mārō mō te pūoro ki te nuinga o ngā uaua). Whakapae ki te 320 kbps mō te huaputa audiophile, 96-128 kbps rānei mō te reo / podcast i reira ko te faila iti iho te arotahi. Ko ngā ūnga kore ngaro MP3 (WAV, FLAC) ka whakakāhore i te whakaritenga bitrate me te pupuri i ia tauira.

Mēnā he kore ngaro te MP3 hanga (WAV, FLAC, ALAC), ka tiakina ngā tauira taketake katoa. Mēnā he ngaro te MP3 (MP3, AAC, OGG, Opus), ka whakawhāiti anō te codec — i te 192 kbps kāore e taea te whakarongo i te rerekētanga mō te nuinga o ngā ihirangi; i te 96 kbps ka taea e koe te whakarongo i ngā pūrere, i ngā pūrere rānei e whakangākau ana. Kāore he pānga ki tēnei te VOB kōpaka — ko ngā whakaritenga codec anake e pā ana.

Mā te pūmau, ā, — ka noho te oro 48 kHz VOB hei oro 48 kHz MP3, ka noho te 44.1 kHz hei oro 44.1 kHz. Mēnā e hiahiatia ana e koe te whakaiti hei ōritetanga (hei tauira, ko ngā māngai whare taiwhanga 96 kHz ki te 44.1 kHz CD-quality MP3) ka mahi tēnei te whakaititanga o te ōrite tauira me te whakarerekētanga o te āhuatanga tiketike.

He — ka tangohia he pūrākau o ngā pūranga VOB ki te rohe whakaata, ā, ka haere tonu tātau ki te whakawātea. He nui ake ngā kaimahi whakawātea a Premium; i runga i tētahi rōpū pūranga 100 (whakahaere pūoro-whitiāhua noa iho) ko tēnei te rerekētanga i waenganui i te 90 waeine me te 8 minu.

He tere ake te whakaterenga reo + transcode i te whakarerekētanga o te whakarerekētanga o te wikiō - i te nuinga o te 5-15% o te roanga pūtake. Ko te 1-ora VOB -> MP3 e whakamutu ana i roto i ngā minu 3-9 i runga i te pūtautau. Mēnā ka ōrite te pūāhuatanga MP3 ki te pūāhuatanga pūtake i roto i te VOB (tōtahi mō AAC i roto i MKV / MP4), he pūāhuatanga mārō, ā, ka haere i ngā takirua.

Mēnā ka rokiroki te VOB pūranga ki ngā raraunga meta (kaitapere, taitara, pūranga), ka tārua mai tātau i ēnei āpure ki te MP3 kāwai e tautoko ana te hanga i ngā tohu. ID3v2 (MP3), Vorbis comments (OGG, FLAC), MP4 atoms (AAC / M4A), RIFF INFO (WAV) kua tuhituhi katoatia. Kāore i whakawāteatia VOB ka whakaputaina i te MP3 — hoatu Mp3tag, Picard rānei i muri i te kawemai hei whakarei.
