MP4 nak nek OGG Konverziós GYIK
How do I extract the audio from a MP4 file as OGG?
+
Upload the MP4 file and we demux the audio track, then transcode to OGG. There is no second video pass and no quality loss beyond the OGG codec itself.
What audio bitrate does the OGG file use?
+
Default OGG bitrate is 192 kbps (transparent for music). You can override to 320 kbps (audiophile) or 96-128 kbps (voice / podcast / smaller file). The choice is exposed in the advanced options.
Will I lose audio quality going from MP4 to OGG?
+
If the OGG format is lossless (WAV, FLAC), you keep every sample exactly. If OGG is lossy (MP3, AAC, OGG), the OGG codec recompresses — quality depends on the bitrate and source audio. We default to 192 kbps which is transparent for almost all content.
Does the extracted OGG keep the original sample rate?
+
By default yes — a 48 kHz audio track in MP4 becomes 48 kHz in OGG. If you need 44.1 kHz (CD-quality) for compatibility with older players, the advanced options include a sample-rate dropdown.
Can I extract audio from multiple MP4 files to OGG in one batch?
+
Yes — drop a folder of MP4 files in and we extract audio in parallel. Premium users get more parallel workers; on a 50-file batch this is the difference between 90 seconds and 8 minutes.
Will the OGG file be tagged with title / artist / album?
+
If the MP4 file has chapter or stream metadata, we copy artist / title / album fields into the OGG container. Otherwise the OGG file is untagged — use a tag editor (Mp3tag, Picard) post-export if you need richer tags.
How long does extracting OGG from a MP4 file take?
+
Audio extraction is much faster than video re-encoding — typically 5-15% of the source duration. A 1-hour MP4 → OGG finishes in 3-9 minutes on the standard pipeline.
Can I extract just a section of the MP4 audio as OGG?
+
Not in this tool — extract the full audio as OGG here, then use /audio-trim/ or /audio-cutter/ to clip the section. The two-step path is usually faster than a combined operation.
Is my MP4 file private during audio extraction?
+
Yes — same privacy model as every conversion: isolated workers, automatic deletion within minutes, no human review of content. See /privacy/.
Why does my OGG file have silent gaps?
+
Silent gaps usually mean the MP4 file had a multi-track audio layout and we picked the wrong stream. Use the advanced "audio stream" option to explicitly pick stream 0, 1, etc., or re-mux all streams to a multi-track OGG container if OGG supports it.
Can the OGG extraction be stereo / mono / 5.1?
+
Channel layout is preserved from MP4 by default — a 5.1 MP4 produces a 5.1 OGG where the codec supports it (AAC, FLAC, OGG). You can force stereo or mono via the channel-downmix option, useful for podcast workflow.
Does the extracted OGG play on iPhone / Android / car stereo?
+
MP3 plays everywhere. AAC / M4A plays on Apple and most Android. OGG / Opus needs a recent player on iOS. The advanced options expose a "device" preset that picks the OGG codec most likely to play on your target.
