How do I turn a Opus audio file into a DivX video?
+
PDF.to wraps your Opus audio into a DivX video with a static cover image (or a generated waveform) as the visual track. Upload the Opus, optionally drop in a cover image, and download the finished DivX.
Why would I convert Opus audio to a DivX video?
+
A DivX video plays everywhere a raw Opus sometimes will not — most notably on video-only platforms and social feeds that require a video container. It is the standard way to publish a podcast, song, or mix as a shareable DivX.
What plays in the picture of the DivX?
+
By default PDF.to shows a single still cover image for the full duration. You can upload your own artwork, or let the converter render an animated waveform that moves with the Opus audio.
Will the audio quality of my Opus change in the DivX?
+
The Opus stream is re-encoded into the DivX container at a high audio bitrate (192 kbps AAC by default), so it stays effectively transparent for music and speech. Lossless Opus sources are not upsampled.
What resolution is the DivX video?
+
The DivX matches the cover image you supply, defaulting to 1280x720. Because the picture is static, a higher resolution adds almost nothing to the file size — the bulk of a DivX made from Opus is the audio.
Can I set a custom thumbnail or cover for the DivX?
+
Yes. Upload any JPG or PNG and PDF.to centers it on a solid background for the whole DivX. This is how you give a Opus track a branded video thumbnail.
Does the DivX keep the title and artist tags from my Opus?
+
Where the DivX container supports metadata, title and artist tags from the Opus are carried over. The cover artwork embedded in the Opus is also used automatically if you do not supply your own.
Can I batch-convert many Opus files to DivX?
+
Yes. Drop a folder of Opus files and each becomes its own DivX video; all of them are zipped for a single download.
Is the Opus to DivX conversion free?
+
Yes, within the free size limit. PRO unlocks much larger Opus uploads, longer durations, and parallel jobs.
How long can the Opus be?
+
Full-length albums and multi-hour Opus recordings convert fine. Because the picture is static, even a long DivX stays modest in size relative to a filmed video of the same length.
Will the DivX play on YouTube, Instagram, and TikTok?
+
Yes. PDF.to encodes the DivX with a widely supported codec and pixel format, so the resulting video uploads cleanly to the major platforms that reject bare Opus audio.
Are my Opus files private during conversion?
+
Uploads are encrypted in transit, the conversion runs in an isolated worker, and both the Opus and the rendered DivX are deleted automatically a short time after you download.
