How VOB to RA Conversion Works
VOB file (VOB) stores data in the VOB format. RA file (RA) stores data in the RA format. This extracts the audio stream from the video container, discarding the video track. The audio track is decoded and re-encoded (or stream-copied if the codec matches) while the video frames are discarded. The result is a standard RA file readable by any compatible application. 1converter handles VOB-to-RA conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
