Add multiple videos and adjust the available video and audio codec settings before processing.

Open the finished WMV file and check fine details, layout and compatibility in the app where you plan to use it.

What is a MP4 file?

MP4 is a widely supported container for video and audio. Compatibility and file size depend on the codecs and settings used inside it, which is why MP4 with H.264 video and AAC audio is a common choice for sharing and uploading.

How to open a MP4 file

MP4 is widely supported by browsers, phones, smart TVs and desktop players. Playback still depends on the video and audio codecs stored inside the file.

What is a WMV file?

WMV (Windows Media Video) is Microsoft’s video format, once common for Windows clips and PowerPoint. It keeps files small but plays poorly outside Windows - Macs, phones and web browsers often can’t open it, so MP4 is the safer choice for sharing.

How to open a WMV file

WMV plays in Windows Media Player and VLC; on Mac, phones or the web, convert it to MP4 first.
