Converting WEBM file to MP4/MPEG4

So I like to convert my game play videos so that I am able to edit them inside of Video editors and I found currently that website convertors are having issues keeping audio in the videos. So I found a work around using VLC player. The MP4 option in VLC is currently not giving my converted WEBM files sound so I have been converting them to MPEG4 files. This has worked so far but if you need them to be in the MP4 format give VLC a try anyway to see if it might work for you. Also sorry for the poor video quality.
