I am working on upscaling some old DVD concert videos. I have ripped my source DVDs and converted the VOB files to MKV in handbrake to de-interlace and add chapters and audio tracks (surround and stereo). I have my audio settings set to “Copy.”
Expected behavior: Both Preview and Video Export would copy ALL audio tracks when “Copy” audio setting is used.
