MP4 → Opus

Heoi, ā, e tika ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ko te Opus 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 Opus mai i tērā, ka ārai katoa i te whakawhitinga rua. Tata tonu ki ia MP4 i te mohoao he ataata H.264 me te oro AAC; kei roto hoki i te kāwai he HEVC, AV1 me VP9. Ko te Opus e whakawhānui ana i te 6 kbps mono speech ki te 510 kbps stereo music i roto i te rererangi ōrite, ā, ka huri noa i ngā āhuatanga.

Heoi, ā, he whiwhinga tūturu i runga i te MP4, kāore he wāhi e whakawhirinaki ana ki te rokiroki i tētahi o ia. Opus 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. Ko Opus te pūkōrero whakapeka pai rawa atu i ngā mokatere iti o te bitrate mā tētahi rohe mārama, ā, ka whakahaua e ia ngā tuhipoka reo WhatsApp, Discord me te WebRTC.

I te nuinga o te wā kāore. MP4 e whakakōrerotia ana e ngā mea katoa, tae atu ki ngā wae o te waka me ngā kaiwhakaari pakeke; Opus e hiahiatia ana he pūmanawa e mōhio ana ki te pūkōrero, ā, kāore i te nuinga o te wā e whai ana i ngā pūrere. Mēnā he pūkōrero waka, he kaiwhakaari whakarerekē rānei te ūnga, he tautohe kaha mō te noho i runga i MP4. Kua tata tonu te kore e tautokona e ngā pūrere takitahi te Opus — e whakaaro ana ki te whakatangitangi pūmanawa anake, ā, e tūmanako ana ngā pūkōrero waka kia whakakāhore i a ia.

Ko te bitrate tōtika mō te ngaro Opus ko te 192 kbps, he mārama mō te pūoro. Ka taea e koe te whakawātea ki te 320 kbps (audiophile), 96-128 kbps rānei (rorohiko / podcast / pūranga iti ake). Ka puta te bitrate dropdown i roto i ngā kōwhiringa tiketike i mua i te kōwhiri i te tahuri.

Mēnā he kore ngaro (WAV, FLAC) te Opus, ka tiakina ngā tauira katoa ki te tika. Mēnā he ngaro te Opus (MP3, AAC, OGG, Opus), ka whakawhāiti anō te pūkōrero Opus te pūtake oro — i te 192 kbps he mārama te hua mō te nuinga o ngā ihirangi. Ka haere te ngaro → kāore i te whakaora i ngā taipitopito kua whakakoretia.

Mā te pūmau, ā, — 48 kHz te oro i roto i tōmu MP4 e noho ana 48 kHz i roto i te huaputa Opus. Mō te pūkōrero CD-burning, te pūkōrero rānei, ka taea e koe te whakawātea ki te 44.1 kHz mā te whakatata i te ōrite tauira; he mātauranga SoX-kitenga nui te tātai.

He — ka tangohia tētahi pūrākau o ngā pūranga MP4, ā, ka tangohia e tātau te oro i te āhua ōrite. Ka whiwhi ngā kaiwhakamaori Premium ki ngā kaimahi ā-tōtahi kē atu; i runga i te 50-file batch ko tēnei te rerekētanga i waenganui i ngā minu me ngā minu tekau.

Mēnā ka mau te MP4 i te wāhanga, i te metadata rānei o te rerenga, ka tārua tātau i ngā āpure taitara / kaitapere / pūrākau ki roto i te Opus. Mēnā kāore, ka puta mai te Opus kāore i te whakahuahua - ka whakamahia te kaiwhakawhanake tohu (Mp3tag, Picard) i muri i te whakahuahua mō te whakahuahua ā-whakahaere.

He tere te reo demux + encoding — i te nuinga o te 5 ki te 15% o te roanga pūtake. Ko te 1-ora MP4 → Opus e whakamutu ana i roto i te 3 ki te 9 minu i runga i te pūtautau paerewa; Ka whakaiti te whakatata Premium i tēnei i ngā mahi whakatōpū.

Kāore i tēnei utauta — ka tangohia te oro katoa hei Opus, kātahi ka whakamahia /oro-trim /, /oro-kuteru rānei hei whakaiti i te wāhanga. He tere ake te ara e rua-whakapae i te mahi whakakotahi, ā, ka hoatu ki a koe te mana tika o te taumata-whakapae.

He — te tauira anō o te āhua o te āhua o ia huringa: kaimahi motuhake, kāore he arotakenga tangata, he whakakore ā-tōtika i roto i ngā minu o te whakamutu. Ko te matapihi o te tiakitanga i roto i /privacy/.
