M2TS wraps H.264/H.265 video at Blu-ray quality (20-50 Mbps) with AC3/DTS surround audio in MPEG-2 Transport Stream packets. WMV (Windows Media Video) is Microsoft's video codec family, using VC-1 (WMV9) encoding in an ASF container. VC-1 was standardized by SMPTE and used alongside H.264 in early Blu-ray discs. Converting M2TS to WMV brings HD content into Microsoft's native video ecosystem.
WMV is required by some legacy Microsoft systems — Windows Movie Maker (pre-2017), older versions of PowerPoint for video embedding, Windows Media Center, and enterprise video distribution systems built on Windows Media Services. Some digital signage, medical imaging, and industrial display systems running Windows Embedded require WMV input. Converting M2TS to WMV ensures compatibility with these Microsoft-centric environments.
FFmpeg re-encodes the M2TS video to WMV9 (VC-1) using the WMV3 encoder. Video resolution can match the source (up to 1080p) with bitrates of 4-15 Mbps depending on quality requirements. Audio is transcoded from AC3/DTS to WMA v2 at 192-320 kbps. The ASF container supports Windows Media metadata and optional DRM. VC-1 uses block-based transform coding with in-loop deblocking and advanced motion compensation.
WMV9/VC-1 produces quality comparable to H.264 at slightly higher bitrates — expect to use 15-20% more bandwidth for equivalent visual quality. At 8-10 Mbps for 1080p, WMV produces very good quality. VC-1 handles film grain and gradients well but shows slightly more blocking than H.264 at lower bitrates.

M2TS to WMV conversion is for legacy Microsoft environments. For modern use, MP4 with H.264 is universally better. Use WMV only when your target system specifically requires it.
