Is it possible to convert .vpj files to .vlc format.
Converting VideoPad Video Editor Project Files directly to a VLC Playlist (.vpj to .vlc conversion) is, per se, not possible.
You will first have to convert your VPJ file to a format supported by the VLC Media Player, for instance MP4. To do so, your only option is using the VideoPad Video Editor itself.
You can then simply add your .mp4 file to a VLC playlist, which will generate a .vlc file.
