WMV (Windows Media Video) is Microsoft's video container format, typically used with Windows Media Player and Windows-based media systems. Like AVI and FLV, converting audio-only AMR to WMV creates a file with an audio track inside a video container. This is primarily needed for legacy Windows applications and media servers that are hardcoded to accept WMV as their input format.
Some Windows-based digital signage systems, presentation software, and legacy intranet media servers only process WMV files. If you need to inject a voice recording into one of these systems, wrapping it in a WMV container may be the only way. Windows Media Player also provides WMV files with a richer playback experience including visualization effects.
FFmpeg decodes the AMR audio and re-encodes it as WMA (wmav2) at 64-128 kbps inside an ASF/WMV container. No video stream is included. The output is a valid WMV file that Windows Media Player and compatible systems will recognize and play. The container includes metadata support for title, artist, and description fields.
WMA encoding at 64 kbps preserves AMR voice content without perceptible loss. Windows Media Player's audio visualization and equalizer features can enhance the listening experience.

AMR to WMV is a niche conversion for legacy Windows media systems. For general audio needs, use MP3, M4A, or WMA directly.
