What changes when you convert MKV to WMA
- Both formats are lossy. Re-encoding adds a second generation of loss, so keep quality high (80+) unless size matters more than fidelity.
- MKV video animation cannot be expressed in WMA audio; the first frame is converted as a still image.
- The video’s audio track is extracted and re-encoded to WMA audio; video frames are discarded.
- WMA audio encoding exposes a quality control; around 80 is the usual sweet spot.
- Encoded with the WMA v2 encoder for compatibility; anything serious should target AAC/MP3 instead.
