Ki jan mwen ka ekstrè son an soti nan dosye MP4 mwen an kòm MP2?
+
Upload MP4 dosye a ak konvètisè a demuxes kouran an odyo, Lè sa a, transcodes li nan MP2. Pa gen okenn dezyèm pase videyo - travès vizyèl la se debarase m de imedyatman se konsa ekstraksyon an se anpil pi vit pase yon re-encode konplè. MP4 se ISO/IEC 14496-14, standardisé an 2001 ak ki sòti nan menm QuickTime bokit layout MOV itilize. MP2 se MPEG-1 Audio Layer II, ki se yon kouch ki te egziste anvan MP3 e ki te vin yon estanda pou DVB ak DAB.
Èske konvèti MP4 nan MP2 se yon dezyèm tou de konpresyon san pèdi tan?
+
Wi, e li vo planifye. De fòma yo se lossy, se konsa MP2 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 MP2 soti nan sa evite double pass tout antye. Preske chak MP4 nan forè a se H.264 videyo ak AAC son; kontenè a tou legalman depoze HEVC, AV1 ak VP9. MP2 se yon fòma ki gen pèt men ki itilize yon filtrebank pi senp pase MP3, ki kouri nan 192 a 384 kbps.
Ki bitrate son ki itilize pa MP2 ki te ekstraye a?
+
A lossy MP2 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 MP2 (WAV, FLAC) ignores the bitrate and keeps every sample.
Èske mwen pral pèdi bon jan kalite son an soti nan MP4 a MP2?
+
Si MP2 se san pèt (WAV, FLAC), chak echantiyon se presye egzakteman. Si MP2 se ak pèt (MP3, AAC, OGG, Opus), MP2 codec recompresses la sous son - a 192 kbps rezilta a se transparan pou prèske tout kontni. Going lossy → san pèt pa janm rekipere detay ki deja depase.
Èske mwen ka ekstrè son soti nan plizyè MP4 dosye nan MP2 nan yon sèl batch?
+
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 pou ekstraksyon MP2 son soti nan yon 1-èdtan MP4 pran?
+
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 mwen ka ekstraksyon sèlman yon pati nan MP4 son kòm MP2?
+
Pa nan zouti sa a dirèkteman — ekstrè son an konplè kòm MP2, Lè sa a, itilize /audio-trim/ oswa /audio-cutter/ pou tranpe seksyon an. Path la de etap se jeneralman pi vit pase yon operasyon konbine epi li bay ou presizyon-nivo fòm-onde kontwòl.
Èske MP4 dosye mwen prive pandan ekstraksyon son an?
+
Yes. Uploaded MP4 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MP2 are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Poukisa dosye MP2 gen espas silendrik kote MP4 te gen son?
+
Usually the MP4 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 MP4 with the track you want first (VLC or ffmpeg can do this) and convert it again.
