FLV до Opus Найчастіші запитання щодо конверсій
How do I extract audio from a FLV video as Opus?
+
Upload your FLV video. PDF.to pulls the audio track out, encodes it to Opus, and gives you a Opus-only download. The video stream is discarded.
Will the audio in the Opus match the original FLV quality?
+
If the source audio is already in a codec compatible with Opus, 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 Opus 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 FLV as Opus?
+
Yes. Use the trim controls on the upload preview to set start and end times before extracting, and only that range becomes Opus.
Does the converter handle FLV files with multiple audio tracks?
+
Yes. If your FLV has several language or commentary tracks, you can pick which one(s) to extract as Opus in the options panel.
Will the Opus 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 FLV to Opus extraction free?
+
Yes, within the free size limit. PRO supports much larger FLV files and parallel batch extraction.
Does PDF.to read or store my FLV content?
+
No. The FLV video and the Opus audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple FLV files?
+
Yes — drop a folder of FLV videos and you will get a ZIP of Opus files back, one per source video.
Will the Opus preserve tags and metadata?
+
Title, artist, and album tags are populated from the FLV 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 FLV legally first, then upload it for Opus extraction.
Why is the Opus file much smaller than the FLV video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the Opus, which is why it can drop from gigabytes to a few megabytes.
