Supports: MTS
This tool transcodes AVCHD camcorder footage (.mts) into Windows Media Video (.wmv) for old Windows-only workflows — Windows Media Player playback, legacy Windows Movie Maker-era projects, or corporate systems standardized on WMV. Be aware this is a step backwards technically: MTS carries efficient H.264 video, and WMV re-encodes it to an older Windows Media codec, so expect some generational quality loss and larger files at a comparable quality. If you only need a modern, universally playable file, convert MTS to MP4 instead — it keeps the efficient codec and plays almost everywhere.

Usually yes, slightly. MTS stores H.264, one of the more efficient video codecs, while this tool re-encodes to WMV 1 or WMV 2 — Microsoft's older Windows Media codecs. Re-encoding to an older, less-efficient codec means you either accept some quality loss at the same file size or a larger file at comparable quality. Keep the Quality Preset high to minimize the visible difference. If quality and file size matter more than WMV compatibility, convert MTS to MP4 instead.
By default it writes WMV 2, the codec identifier for Windows Media Video 8, paired with WMA v2 audio in an ASF container — both play natively in Windows Media Player. You can switch the Video Codec to WMV 1 for very old players. Note this tool does not output VC-1 (the SMPTE-standardized successor based on Windows Media Video 9), so for the most efficient Microsoft codec a desktop encoder is a better fit.
For most people, MP4 is the better target — it is smaller, higher quality, and plays on virtually every device. WMV makes sense in narrow cases: a Windows Media Player-only environment, an older Windows Movie Maker-era project that expects WMV input, or a corporate or kiosk setup standardized on Windows Media. Outside those, convert MTS to MP4 is the modern choice.
Effectively yes. Both are AVCHD clips in an MPEG transport stream — camcorders commonly write .mts on the SD card, and the same footage is often labeled .m2ts after import to a computer. The underlying video (H.264) and audio (Dolby AC-3 or PCM) are identical, so this converter treats them the same way.
WMV is not the most space-efficient target, so if your goal is a smaller file rather than WMV specifically, downscale the resolution and lower the Quality Preset, or use the dedicated Video Compressor with the output left at the source format. In our testing, the same 1080p AVCHD clip produced a noticeably larger file as WMV 2 than as H.264 MP4 at a matching visual quality, because the older Windows Media codec compresses less efficiently.
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion. There is no sign-up, no watermark, and your footage is never shared or made public.
