Converting .vjp files to .mp4 format.
Converting Visual Studio J++ Projects directly to MPEG-4 Videos (.vjp to .mp4 conversion) is not possible, since VJP files do not contain any multimedia data whatsoever.
We are not aware of any video editing software or (online) conversion tool capable of converting VJP to MP4.
But perhaps this is just a typo, and you are actually searching for ways how to convert VideoPad Video Editor Projects to MPEG-4 Videos. In that case, please refer to the VPJ to MP4 conversion entry.
In a word, direct vjp to mp4 conversion is not possible.
So don't expect any so-called vjp to mp4 converter or vjp to mp4 free online conversion tool available.
The database currently does not contain any vjp software converter.
