Step-by-step instructions

Upload your MP4 file
Select your MP4 file. The converter will re-encode the H.264 video to WMV3 (Windows Media Video 9) and AAC audio to WMA.

Choose WMV as output
Select WMV. Bitrate auto-set to match the source quality. WMV uses Microsoft's older codec, so the resulting file may be larger than the MP4 source for similar quality.

Set quality settings
For PowerPoint embedding, choose 'Medium' or 720p — lower bitrates produce smaller, more reliable embeds. For archival, use 'High' or 1080p.

Download and use in Windows
The WMV file plays natively in Windows Media Player, embeds cleanly in PowerPoint 2007–2019, and works in Windows Movie Maker.
