How to Convert WMV to MP4 on Mac

A WMV file is a codec that stands for Windows Media Video file developed by Microsoft. It is contained within Microsoft Advanced System Formats. It contains high-quality video but not as much as an MP4 file. WMV was the most common type of media file back in the 2000s due to the popularity of Windows. MP4 files, on the other hand, offer much better quality than WMV files and are compatible with almost all devices. We have created this guide to help you convert WMV to MP4 on Mac.

You can convert the files by firstly downloading the VLC player on your Mac. Now, go to File on the top menu options and select Convert/Stream. Drag your WMV file to the dialogue box. Go to the Choose Profile section and select the Video – H.264 + MP3 (MP4) from the list. Next, you need to click on Customize button, and under the Video Codec section, check the box beside Keep original audio track. After this, simply select the destination and click on Save.
