VOB до M4R Найчастіші запитання щодо конверсій
How do I extract audio from a VOB video as M4R?
+
Upload your VOB video. PDF.to pulls the audio track out, encodes it to M4R, and gives you a M4R-only download. The video stream is discarded.
Will the audio in the M4R match the original VOB quality?
+
If the source audio is already in a codec compatible with M4R, 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 M4R output?
+
Типово, 192 кбіт/ с. На панелі параметрів буде показано 96, 128, 192, 256 і 320 кб/ с } обрати вище для музики, нижче для голосу.
Can I extract only part of the VOB as M4R?
+
Yes. Use the trim controls on the upload preview to set start and end times before extracting, and only that range becomes M4R.
Does the converter handle VOB files with multiple audio tracks?
+
Yes. If your VOB has several language or commentary tracks, you can pick which one(s) to extract as M4R in the options panel.
Will the M4R output have the same sample rate as the source?
+
Так, типово. Ми не переписуємо, якщо ви не надсилаєте явного запиту. 48 кГц зберігається з джерел фільмів, 44. 1 кГц з джерел музики.
Is the VOB to M4R extraction free?
+
Yes, within the free size limit. PRO supports much larger VOB files and parallel batch extraction.
Does PDF.to read or store my VOB content?
+
No. The VOB video and the M4R audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple VOB files?
+
Yes — drop a folder of VOB videos and you will get a ZIP of M4R files back, one per source video.
Will the M4R preserve tags and metadata?
+
Title, artist, and album tags are populated from the VOB container metadata when available. You can edit them after extraction with our audio-tag tool.
Чи працює перетворювач для потокових відео URL?
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the VOB legally first, then upload it for M4R extraction.
Why is the M4R file much smaller than the VOB video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the M4R, which is why it can drop from gigabytes to a few megabytes.
