MP4 үчүн DTS Конверсия боюнча көп берилүүчү суроолор
How do I extract just the audio track from MP4 as DTS?
+
Upload the MP4 file and the converter demuxes the audio stream from the MP4 container, then transcodes it into DTS. Video frames are discarded — no second video pass, no quality loss beyond what the DTS codec itself introduces.
Which audio track gets extracted when my MP4 has several?
+
By default stream 0 (the first audio track, usually the main mix). If your MP4 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 DTS file use?
+
Default DTS 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 DTS targets (WAV, FLAC) ignore the bitrate setting and keep every sample.
Will going from MP4 to DTS reduce my audio quality?
+
If the DTS format is lossless (WAV, FLAC, ALAC), every original sample is preserved. If DTS 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 MP4 container has no influence on this — only the codec settings matter.
Does the extracted DTS keep the MP4 sample rate?
+
By default yes — 48 kHz MP4 audio becomes 48 kHz DTS 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 DTS) the sample-rate dropdown does this with high-quality resampling.
Can I batch-extract DTS audio from a folder of MP4 files?
+
Yes — drop a folder of MP4 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 DTS from a 1-hour MP4 take?
+
Audio demux + transcode runs much faster than video re-encoding — typically 5-15% of source duration. A 1-hour MP4 -> DTS finishes in 3-9 minutes on the standard pipeline. If the DTS codec matches the source codec already in the MP4 (common for AAC inside MKV / MP4), it is a pure remux and runs in seconds.
Will the DTS file carry title / artist / album tags?
+
If the MP4 file stores stream metadata (artist, title, album), we copy those fields into the DTS container where the format supports tags. ID3v2 (MP3), Vorbis comments (OGG, FLAC), MP4 atoms (AAC / M4A), RIFF INFO (WAV) are all written. Untagged MP4 produces untagged DTS — use Mp3tag or Picard post-export to enrich.
Is my MP4 private during audio extraction?
+
Yes — same privacy model as every conversion. Source MP4 and output DTS are processed in isolated workers and deleted within minutes. We never play, store, or share content. See /privacy/.
Why does my DTS have silent gaps or wrong audio?
+
Almost always a stream-index mismatch — your MP4 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 DTS file.
Can the DTS extraction be stereo, mono, or 5.1?
+
Channel layout follows the MP4 by default: a 5.1 MP4 audio stream produces a 5.1 DTS 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 DTS 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 DTS codec for the target you select.
