Frequently asked questions
Does ASF to VOB lose quality?
Yes. VOB is an MPEG-2 Program Stream, so the ASF's WMV or VC-1 video is re-encoded to MPEG-2. That is lossy, and MPEG-2 is larger than modern codecs at the same quality.
Why convert ASF to VOB?
VOB is the DVD video format, so you convert when authoring DVD-Video or targeting players that read MPEG-2 program streams.
Where does a VOB file open?
VOB opens in VLC on Windows, macOS and Linux. For a standalone DVD player the file must also meet DVD-Video resolution and bitrate rules.
What is lost, and will DRM convert?
DRM-protected ASF/WMV cannot be converted. For unprotected files the video is re-encoded to MPEG-2 and audio remultiplexed, and HD sources are commonly reduced to DVD standard definition.
