Convert VVF to MP3

Although your options might be somewhat limited, converting CCTV DVR Camera Video Files directly to MP3 Audio Files (.vvf to .mp3 conversion) should be possible. Such attempts relate to users seeking for ways to extract the audio track in MP3 format from a VVF recording.

One good option seems to be using the Bigasoft Total Video Converter, which allows users to import VVF recordings and export their extracted audio track in MP3 format.
