AVI and WMV are both Microsoft video formats, but they target different use cases. AVI (1992) uses the RIFF structure and can hold virtually any codec, making it a flexible but aging container. WMV uses the ASF (Advanced Systems Format) container with Windows Media Video codecs — WMV3 (VC-1) was standardized as SMPTE 421M and was competitive with H.264 at its peak. Converting AVI to WMV transcodes the video into Microsoft's streaming-capable format, which was the standard for Windows-based video delivery from 2000 to 2015.
WMV's ASF container supports streaming, DRM, and metadata features that AVI lacks entirely. If you need to deliver video through legacy Windows Media Services, embed video in older PowerPoint (2003–2010) presentations, or produce content for legacy Windows-based digital signage systems, WMV is the expected format. Some enterprise environments still standardize on WMV for internal video distribution.
FFmpeg decodes the AVI input and re-encodes video to WMV2 (Windows Media Video 8) or WMV3/VC-1 (Windows Media Video 9) at the selected bitrate. Audio is encoded to WMA v2 at 128–192 kbps. The output is wrapped in an ASF container with the .wmv extension. VC-1 (WMV3) supports resolutions up to 1080p with quality competitive with early H.264 implementations. The ASF container includes metadata, seeking information, and optional DRM hooks.
VC-1 (WMV3) at 4–8 Mbps for 720p delivers quality roughly comparable to H.264 Main Profile at the same bitrate, though modern H.264 encoders (x264) have improved significantly since then. WMV2 at 1080p requires higher bitrates (10–15 Mbps) for acceptable quality. For legacy playback scenarios at 480p or 720p, WMV produces perfectly adequate results.

AVI to WMV conversion bridges the gap between AVI's raw container and Microsoft's streaming-capable format. While WMV has been largely superseded by MP4 for new projects, it remains necessary for legacy Windows infrastructure.
