VLC is one of the most flexible media players for Windows. That media player even enables its users to merge multiple videos into one clip with its command-line video merge tool.

The Merge videos together page on VLC’s support site includes guidelines for how to merge videos with VLC.

However, VLC’s merge videos feature won’t work if the source files for the merged video aren’t of the same format and if any of them have portrait orientations (such as clips recorded with mobiles).

Furthermore, VLC’s video merging might not work for users who need to update that media player’s codecs.

What can I do if the VLC video merge option is not working?

1. Use Any Video Converter Ultimate

If not, one of your source files for the video might be corrupted. So, also check that all the video source files play ok before merging them.
