MOV pou WMA FAQ sou Konvèsyon
Ki jan mwen ka ekstraksyon sèlman travès la odyo soti nan MOV kòm WMA?
+
Upload MOV dosye a ak konvètisè a demuxes kouran odyo a soti nan MOV kontenè a, Lè sa a, transcodes li nan WMA. Frames videyo yo te depase - pa gen dezyèm pase videyo, pa gen okenn pèt kalite pi lwen pase sa ki nan WMA codec li menm prezante. MOV se Apple QuickTime bwat, ki te livre nan 1991 ak toujou fòma a iPhone, iPad oswa Final Cut Pro timeline ekri pa défaut. WMA se Windows Media Audio, Microsoft's repons pou MP3, lanse an 1999 ak ki te konpile ak chak Windows enstalasyon de sa a era.
Èske konvèti MOV nan WMA se yon dezyèm tou de konpresyon san pèdi tan?
+
Wi, e li vo planifye. De fòma yo se lossy, se konsa WMA encoder travay soti nan son ki te deja pase pa yon pass psychoacoustic, ak li tèt li desizyon yo konpoze premye set. A 192 kbps oswa pi wo a rezilta a se toujou transparan pou pifò tande. Si ou gen yon master lossless nenpòt kote, enkodaj WMA soti nan sa evite double pass tout antye. Yon MOV nòmalman pote H.264 oswa HEVC pou livrezon, oswa ProRes lè li se yon edisyon maître, ansanm ak AAC oswa PCM san konpresyon son. WMA se lossy pa default, nan yon ASF kontenè, ak varyasyon lossless ak vwa-optimise ki raman te rankontre.
Èske WMA ap jwe nan machin mwen oswa sou hardware ki pi ansyen?
+
Pafwa pa. MOV se dekode pa esansyèlman tout bagay, ki gen ladan yunit tèt machin ak jwè ki gen laj; WMA bezwen lojisyèl ki konnen codec la, ki se souvan pa gen pyès ki nan konpitè standalone. Si destinasyon an se yon stereo machin oswa yon jwè portatif, sa a se yon argumentasyon fò pou rete sou MOV. WMA se pa sipòte prèske nenpòt kote deyò Windows, ak fichiers WMA pi gran ka pote DRM ki bloke konvèsyon an tout antye.
Ki travès son ki sòti lè MOV mwen gen plizyè?
+
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.
Ki bitrate ki itilize pa WMA?
+
A lossy WMA 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 WMA (WAV, FLAC) ignores the bitrate and keeps every sample.
Èske mwen pral soti nan MOV a WMA diminye bon jan kalite son mwen?
+
Si fòma WMA se san pèt (WAV, FLAC, ALAC), tout echantiyon orijinal yo pral konsève. Si WMA se san pèt (MP3, AAC, OGG, Opus), codec la pral re-kompression — a 192 kbps diferans lan pa tande pou pifò kontni; a 96 kbps ou ka tande cymbals oswa sibilants mouye. MOV kontenè a pa gen okenn efè sou sa — sèlman paramèt codec la ki enpòtan.
Èske WMA ekstraksyon an kenbe MOV vitè echantiyon?
+
Pa default, wi — 48 kHz MOV son vin 48 kHz WMA son, 44.1 kHz vin 44.1 kHz. Si ou bezwen fè yon downsampling pou kompatibilite (e. g. 96 kHz studio masters pou 44.1 kHz CD-quality WMA) lis drop-down pou frekans-sampling la fè sa ak yon resampling bon kalite.
Èske mwen ka batch-extraire WMA son soti nan yon folder nan MOV fichiers?
+
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.
Ki sa ki tan li pran pou ekstraksyon WMA soti nan yon 1- èdtan MOV?
+
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.
Èske MOV mwen an prive pandan ekstraksyon son?
+
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 WMA are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Poukisa WMA mwen an gen espas silans oswa son ki pa kòrèk?
+
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.
