What to expect

  • Conversion always re-encodes video and audio - WMV/WMA become H.264/AAC - so there is a small quality loss compared to the original.
  • DRM-protected WMV files cannot be converted by any free tool; they must be played in an authorised licensed player instead.
  • The output MP4 is usually smaller than the source WMV because H.264 is more efficient than older WMV codecs.

Frequently asked questions

Will I lose quality converting WMV to MP4?
Some loss is unavoidable because the video is decoded and re-compressed. At default HandBrake settings the difference is rarely visible.
Why won't my WMV file convert?
The most likely cause is DRM protection - open the file in VLC first to check. If it plays there but HandBrake fails, try ffmpeg or verify the file is not corrupted.
How long does conversion take?
A 10-minute 1080p WMV takes roughly 2-5 minutes with HandBrake on a modern CPU.
Does the WMV audio survive the conversion?
Yes - the WMA audio track is automatically re-encoded to AAC, which is the standard audio codec for MP4 files.
