WMV (Windows Media Video) is Microsoft's video container format based on ASF (Advanced Systems Format). Converting FLAC to WMV wraps audio inside a video container — an uncommon operation typically required for legacy Windows-based media systems, kiosks, or PowerPoint presentations from the pre-MP4 era. The audio is encoded as WMA inside the WMV container, optionally with a static image as a placeholder video track.
Certain legacy Windows enterprise systems, digital signage platforms, and older versions of Microsoft Office embed WMV files for multimedia content. Some corporate training platforms from the 2000s-2010s only accept WMV uploads. Converting FLAC to WMV with a static image creates a 'video' file that plays audio content within these constrained environments.
FFmpeg decodes FLAC and encodes audio as WMA (wmav2) inside a WMV/ASF container. For a valid video file, a minimal video track is needed — typically a 1-second loop of a static image encoded with WMV2 or VC-1. The ASF container supports multiple audio and video streams with indexing for seeking. WMV does not support AAC, Vorbis, or Opus audio — only WMA variants and MP3.
Audio quality depends on the WMA encoding bitrate. At 192 kbps WMA, quality is good for general listening. At 320 kbps, quality is excellent. The WMV container itself adds no audio quality overhead. If a video track is included, its quality is irrelevant (just a static placeholder image).

FLAC to WMV conversion exists for legacy Windows ecosystem compatibility. Unless your target system specifically requires WMV, use MP4 or MKV which are more modern and widely supported.
