How to Convert MP4 to WMV

WMV (Windows Media Video) is Microsoft's video format from the Windows Media era. Converting MP4 to WMV is a niche need today — most modern systems prefer MP4 — but specific situations still require WMV: corporate Windows environments where IT policy disables third-party codecs, PowerPoint files distributed to old Windows 7 machines, Windows Movie Maker projects, and a long tail of legacy Microsoft-only software. This guide covers when WMV actually helps, when it doesn't, and how to convert when you genuinely need to.

Open MP4 to WMV Converter

Quick answer

FFmpeg: `ffmpeg -i input.mp4 -c:v wmv2 -b:v 2M -c:a wmav2 -b:a 192k output.wmv`. HandBrake: doesn't directly support WMV (focus on MP4/MKV) — use FFmpeg or online tool. For PowerPoint embedding in 2026, modern PowerPoint plays MP4 natively — only convert to WMV if your viewers are on Windows 7 or older.

Method 1: Convert MP4 to WMV online (free, in your browser)

  1. 1

    Open the FormatDrop video converter

    Open formatdrop.com/video-converter in your browser. Upload your MP4 — conversion runs locally.

    Go to converter
  2. 2

    Drop your MP4 file

    Drag the .mp4 file. The converter detects H.264 video and AAC/MP3 audio, and re-encodes to WMV3 video + WMA audio.

  3. 3

    Choose WMV and bitrate

    Select WMV. Set video bitrate: 2 Mbps for 720p, 4 Mbps for 1080p, 8 Mbps for archival. WMV is less efficient than H.264, so files are typically 30-50% larger at equivalent quality.

  4. 4

    Download and use in Windows

    The WMV plays natively in Windows Media Player on every version of Windows, embeds in PowerPoint 2007-2019, and works in Windows Movie Maker.

Method 2Command line (FFmpeg)

Method 2: Convert MP4 to WMV with FFmpeg

FFmpeg is the standard command-line tool for video conversion.

  1. Install. Mac: `brew install ffmpeg`. Windows: download from ffmpeg.org. Linux: `apt install ffmpeg`.
  2. Standard conversion: `ffmpeg -i input.mp4 -c:v wmv2 -b:v 2M -c:a wmav2 -b:a 192k output.wmv`.
  3. Higher quality: `ffmpeg -i input.mp4 -c:v wmv2 -b:v 4M -c:a wmav2 -b:a 192k output.wmv` (4 Mbps for 1080p).
  4. Older WMV (Windows 7-compatible): `ffmpeg -i input.mp4 -c:v msmpeg4v3 -b:v 2M -c:a wmav2 output.wmv`.
  5. Batch: `for f in *.mp4; do ffmpeg -i "$f" -c:v wmv2 -b:v 2M -c:a wmav2 -b:a 192k "${f%.mp4}.wmv"; done`.

Note: wmv2 is the standard WMV9 codec; works on Windows XP+ via Windows Media Player. For older XP Media Center compatibility, use msmpeg4v3.

Method 3Windows Movie Maker (legacy)

Method 3: Use Windows Movie Maker on Windows (free, legacy but works)

Windows Movie Maker (officially discontinued but still available via archives) imports MP4 and exports WMV natively.

  1. Download Windows Movie Maker (legacy installer from Internet Archive).
  2. File → Import Media → select your MP4.
  3. Drag MP4 to the timeline.
  4. File → Save Movie → choose 'For computer' or 'High definition'. Movie Maker exports as WMV automatically.

Note: Movie Maker is unmaintained since 2017. Use FFmpeg or HandBrake for modern reliable conversion. Movie Maker is convenient if you already have it installed.

Method 4VLC Media Player

Method 4: Convert MP4 to WMV with VLC

VLC's Convert/Save feature handles MP4-to-WMV conversion.

  1. Open VLC → Media → Convert/Save.
  2. Add your MP4 → Convert/Save.
  3. Profile dropdown → click the wrench icon to create a custom profile with WMV2 video codec, WMA audio codec, ASF container.
  4. Set destination filename with .wmv extension. Click Start.

Note: VLC's WMV profiles aren't built in by default; you must create one. FFmpeg is more straightforward for one-off conversion.

When you need to convert MP4 to WMV

  • 1

    Embedding video in PowerPoint for distribution to old Windows 7 machines

    PowerPoint 2007-2010 with Windows 7 sometimes plays WMV more reliably than MP4. For modern audiences on Windows 10/11 with current PowerPoint, MP4 is fine.

  • 2

    Corporate environments with strict codec policies

    Some IT departments block H.264 codec installation but allow Windows Media. WMV plays without any extra software.

  • 3

    Windows Movie Maker projects

    Movie Maker (now discontinued but still in use) imports MP4 inconsistently. WMV is its native format.

  • 4

    Legacy capture or playback systems

    Some surveillance NVRs, older media servers, and broadcast capture cards expect WMV.

Troubleshooting common MP4 to WMV problems

Converted WMV doesn't play in Windows Media Player

Try `msmpeg4v3` codec instead of wmv2 for older Windows compatibility: `ffmpeg -i input.mp4 -c:v msmpeg4v3 -b:v 2M -c:a wmav2 output.wmv`.

WMV is much larger than the MP4

WMV is less efficient than H.264 — that's expected. For smaller WMV files, lower the bitrate (`-b:v 1M`) at the cost of quality. There's no way to make WMV match H.264 efficiency.

Audio is missing or out of sync

WMA may not handle some MP3 audio variants. Force AAC-then-WMA: `ffmpeg -i input.mp4 -c:v wmv2 -b:v 2M -c:a wmav2 -b:a 192k -async 1 output.wmv`.

Why convert MP4 to WMV?

WMV is Windows Media's video format from the early 2000s. Most modern Microsoft tools — current PowerPoint, Windows Media Player on Windows 10/11, Edge, Office 365 — handle MP4 natively, making WMV largely obsolete. The legitimate reasons to convert are narrow: PowerPoint files distributed to Windows 7 viewers, restrictive corporate IT environments, or legacy Microsoft software that still expects WMV.

For cross-platform sharing, MP4 is dramatically better. WMV doesn't play natively on Mac, iOS, Android, smart TVs, or any modern web browser. If your audience is mixed, keep MP4.

Your files never leave your device

FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.

Frequently asked questions

Should I convert MP4 to WMV in 2026?
Probably not — modern PowerPoint, Windows Media Player on Windows 10/11, and every other Microsoft tool plays MP4 natively. Only convert if you're targeting Windows 7 or older, restrictive corporate IT policies, or legacy Microsoft-only software.
Will WMV play on a Mac?
Not natively. macOS has no built-in WMV decoder. VLC plays WMV on Mac. Flip4Mac was the legacy plugin (now discontinued). Modern Mac users should stick with MP4.
FFmpeg command for MP4 to WMV?
`ffmpeg -i input.mp4 -c:v wmv2 -b:v 2M -c:a wmav2 -b:a 192k output.wmv`. For higher quality, raise video bitrate.
Best free MP4 to WMV converter?
FFmpeg (command line, cross-platform). For Windows users who prefer GUI: VLC works after creating a custom WMV profile. The browser tool handles single-file conversion without install.
