MP4 в MP2 Часто задаваемые вопросы о конвертации
How do I extract the audio from a MP4 file as MP2?
+
Upload the MP4 file and we demux the audio track, then transcode to MP2. There is no second video pass and no quality loss beyond the MP2 codec itself.
What audio bitrate does the MP2 file use?
+
По умолчаниюMP2 битрат составляет 192 кбит (транспарентно для музыки). Вы можете переключить на 320 кбит/с (аудиофил) или 96-128 кбит/с (счет/подкаст/меньший файл). Выбор открыт в усовершенствованных опциях.
Will I lose audio quality going from MP4 to MP2?
+
If the MP2 format is lossless (WAV, FLAC), you keep every sample exactly. If MP2 is lossy (MP3, AAC, OGG), the MP2 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 MP2 keep the original sample rate?
+
By default yes — a 48 kHz audio track in MP4 becomes 48 kHz in MP2. 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 MP2 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 MP2 file be tagged with title / artist / album?
+
If the MP4 file has chapter or stream metadata, we copy artist / title / album fields into the MP2 container. Otherwise the MP2 file is untagged — use a tag editor (Mp3tag, Picard) post-export if you need richer tags.
How long does extracting MP2 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 → MP2 finishes in 3-9 minutes on the standard pipeline.
Can I extract just a section of the MP4 audio as MP2?
+
Не в этом инструменте — вытащить полный звук как MP2 здесь, затем использовать /audio-trim/ или /audio-cutter/ для зажима секции. Двухступенчатый путь обычно быстрее, чем комбинированная операция.
Is my MP4 file private during audio extraction?
+
Да — та же модель конфиденциальности, что и любое преобразование: изолированные работники, автоматическое исключение в течение минут, отсутствие человеческого обзора содержания. См. / Privaty/.
Why does my MP2 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 MP2 container if MP2 supports it.
Can the MP2 extraction be stereo / mono / 5.1?
+
Channel layout is preserved from MP4 by default — a 5.1 MP4 produces a 5.1 MP2 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 MP2 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 MP2 codec most likely to play on your target.
