MOV đến AIFF Câu hỏi thường gặp về chuyển đổi
How do I extract just the audio track from MOV as AIFF?
+
Upload the MOV file and the converter demuxes the audio stream from the MOV container, then transcodes it into AIFF. Video frames are discarded — no second video pass, no quality loss beyond what the AIFF codec itself introduces.
Which audio track gets extracted when my MOV has several?
+
By default stream 0 (the first audio track, usually the main mix). If your MOV carries commentary, dubs, or descriptive audio on additional tracks, the advanced "audio stream" picker lets you pick 1, 2, 3... explicitly. The track list is shown in the upload preview so you do not pick blind.
What bitrate does the AIFF file use?
+
Default AIFF bitrate is 192 kbps (transparent for music to most ears). Override to 320 kbps for audiophile output, or 96-128 kbps for voice / podcast where the smaller file is the priority. Lossless AIFF targets (WAV, FLAC) ignore the bitrate setting and keep every sample.
Will going from MOV to AIFF reduce my audio quality?
+
If the AIFF format is lossless (WAV, FLAC, ALAC), every original sample is preserved. If AIFF is lossy (MP3, AAC, OGG, Opus), the codec recompresses — at 192 kbps the difference is inaudible for most content; at 96 kbps you may hear cymbals or sibilants softening. The MOV container has no influence on this — only the codec settings matter.
Does the extracted AIFF keep the MOV sample rate?
+
By default yes — 48 kHz MOV audio becomes 48 kHz AIFF audio, 44.1 kHz becomes 44.1 kHz. If you need to downsample for compatibility (e.g. 96 kHz studio masters to 44.1 kHz CD-quality AIFF) the sample-rate dropdown does this with high-quality resampling.
Can I batch-extract AIFF audio from a folder of MOV files?
+
Yes — drop a folder of MOV files into the upload zone and we run extraction in parallel. Premium gets more parallel workers; on a 100-file batch (typical music-video collection) this is the difference between 90 seconds and 8 minutes.
How long does extracting AIFF from a 1-hour MOV take?
+
Audio demux + transcode runs much faster than video re-encoding — typically 5-15% of source duration. A 1-hour MOV -> AIFF finishes in 3-9 minutes on the standard pipeline. If the AIFF codec matches the source codec already in the MOV (common for AAC inside MKV / MP4), it is a pure remux and runs in seconds.
Will the AIFF file carry title / artist / album tags?
+
If the MOV file stores stream metadata (artist, title, album), we copy those fields into the AIFF container where the format supports tags. ID3v2 (MP3), Vorbis comments (OGG, FLAC), MP4 atoms (AAC / M4A), RIFF INFO (WAV) are all written. Untagged MOV produces untagged AIFF — use Mp3tag or Picard post-export to enrich.
Is my MOV private during audio extraction?
+
Yes — same privacy model as every conversion. Source MOV and output AIFF are processed in isolated workers and deleted within minutes. We never play, store, or share content. See /privacy/.
Why does my AIFF have silent gaps or wrong audio?
+
Almost always a stream-index mismatch — your MOV had a multi-track audio layout and we extracted the wrong stream (e.g. the silent descriptive audio track instead of the main mix). Re-run with the advanced "audio stream" option set to the right index, or pick "all streams" to extract every track as a separate AIFF file.
Can the AIFF extraction be stereo, mono, or 5.1?
+
Channel layout follows the MOV by default: a 5.1 MOV audio stream produces a 5.1 AIFF where the codec supports it (AAC, FLAC, OGG, Opus). The channel-downmix option forces stereo or mono — useful for podcast workflow or compatibility with mono-only Bluetooth speakers.
Will the extracted AIFF play on iPhone / Android / car stereo?
+
MP3 plays universally. AAC / M4A plays on Apple and most Android, including factory car stereos from 2014+. OGG / Opus needs a recent player and may not work in older infotainment systems. The advanced device-target dropdown picks the safest AIFF codec for the target you select.
