MP4 kepada MP2 Soalan Lazim Penukaran
How do I extract audio from a MP4 video as MP2?
+
Upload your MP4 video. PDF.to pulls the audio track out, encodes it to MP2, and gives you a MP2-only download. The video stream is discarded.
Will the audio in the MP2 match the original MP4 quality?
+
If the source audio is already in a codec compatible with MP2, we stream-copy without re-encoding — bit-identical to the original. Otherwise we re-encode at 192 kbps by default for near-transparent quality.
What bitrate is the MP2 output?
+
192 kbps secara lalai. Panel pilihan memaparkan 96, 128, 192, 256, dan 320 kbps — pilih lebih tinggi untuk muzik, lebih rendah untuk suara.
Can I extract only part of the MP4 as MP2?
+
Yes. Use the trim controls on the upload preview to set start and end times before extracting, and only that range becomes MP2.
Does the converter handle MP4 files with multiple audio tracks?
+
Yes. If your MP4 has several language or commentary tracks, you can pick which one(s) to extract as MP2 in the options panel.
Will the MP2 output have the same sample rate as the source?
+
Ya secara lalai. Kami tidak sampel semula melainkan anda secara eksplisit memintanya. 48 kHz dipelihara dari sumber filem, 44.1 kHz dari sumber muzik.
Is the MP4 to MP2 extraction free?
+
Yes, within the free size limit. PRO supports much larger MP4 files and parallel batch extraction.
Does PDF.to read or store my MP4 content?
+
No. The MP4 video and the MP2 audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple MP4 files?
+
Yes — drop a folder of MP4 videos and you will get a ZIP of MP2 files back, one per source video.
Will the MP2 preserve tags and metadata?
+
Title, artist, and album tags are populated from the MP4 container metadata when available. You can edit them after extraction with our audio-tag tool.
Adakah penukar berfungsi pada URL video strim?
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the MP4 legally first, then upload it for MP2 extraction.
Why is the MP2 file much smaller than the MP4 video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the MP2, which is why it can drop from gigabytes to a few megabytes.
