Why in-browser AVI to WMV is not possible
WMV uses Microsoft's proprietary VC-1 / WMV9 codec. Browser APIs (WebCodecs, MediaRecorder) only support open codecs — H.264, VP8, VP9, AV1. No JavaScript library can legally encode to WMV. FFmpeg, which is open-source and runs locally on your machine, is the correct and fastest tool for this job. Your video never leaves your device.
How to install FFmpeg
Windows
winget install ffmpeg
