MOV → AMR

Heoi, ā, e tika ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ko te AMR 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 AMR mai i tērā, ka kore e taea te whakawhiti i te whakawhitinga rua katoa. Ko te tikanga ka mau te MOV i te H.264, HEVC rānei mō te whakarato, i te ProRes rānei ina mahia he kaikōrero whakahua, i te taha rānei o te AAC, te oro PCM rānei kāore i te whakawhāiti. Ko te AMR he pūkōrero kōrero whāiti e haere ana i waenganui i te 4.75 me te 12.2 kbps, e tauira ana i te whakawhitinga reo tangata i te wā o te pūoro pūoro katoa.

Nā te mea he pūkōrero kōrero tētahi taha o te pūkōrero, ehara i te pūkōrero pūoro. E tauira ana i te pūkōrero tangata, ā, ka whakakore i ngā mea katoa i waho o te awhe whatunga, he pai mō te pūrongo reo, he tūkino hoki mō ngā mea katoa me ngā pūrere i roto. Kāore e taea te whakaora i ngā auautanga kāore i te ngaro - kāore anō kia waihangatia i te tuatahi. He nui nga faila MOV, ā, i waho o te tautoko pānui Apple he nui ake i te MP4 — ka whakakāhoretia e ngā hanganga Android tawhito me ētahi Smart TV.

One track, picked automatically: normally the main one, the track with the most channels. This page has no setting to choose a different track and does not list the tracks in the file. If you need commentary or a dub instead, remux the MOV with that track first (VLC or ffmpeg can do this) and convert it again.

A lossy AMR is encoded at 192 kbps by default. The Audio Quality setting also offers 320 kbps for the best quality and 128 kbps for a smaller file. A lossless AMR (WAV, FLAC) ignores the bitrate and keeps every sample.

Mēnā he kore ngaro te AMR hanga (WAV, FLAC, ALAC), ka tiakina ngā tauira taketake katoa. Mēnā he ngaro te AMR (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 MOV kōpaka — ko ngā whakaritenga codec anake e pā ana.

Mā te pūmau, ā, — ka noho te oro 48 kHz MOV hei oro 48 kHz AMR, 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 AMR) ka mahi tēnei te whakaititanga o te ōrite tauira me te whakarerekētanga o te āhuatanga tiketike.

Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.

It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.

Yes. Uploaded MOV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted AMR are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.

Usually the MOV carries more than one audio track and the one that was converted is silent or secondary. The converter picks one audio track automatically, normally the main one, and this page has no setting to choose a different track. If the wrong one comes out, remux the MOV with the track you want first (VLC or ffmpeg can do this) and convert it again.
