Convert FBR to VLC

Converting FlashBack Screen Recordings directly to a VLC Playlist (.fbr to .vlc conversion) is, per se, not possible.

You will first have to convert your FBR file to a format supported by the VLC Media Player, for instance MP4. For that, you can use programs, such as FlashBack Express or Bigasoft Total Video Converter.

You can then simply add your .mp4 file to a VLC playlist, which will generate a .vlc file.

Simply put, it is impossible to convert FBR to VLC directly.
Thus, there is no so-called fbr to vlc converter or a free online .fbr to .vlc converter to be found.
