VPJ (VideoPad Video Editor Project File)
The VPJ Video file format
VPJ files are project files primarily associated with the VideoPad Video Editor, a video editing and creation software. The project file includes information about video transitions and other effects applied to the video data, audio streams, and references to the location of the video clips used.
Technical details of VPJ files
Project files like VPJ are useful for video editors to save their work in progress. Various video formats can function as an input for the project file. Since VPJ files are merely project files, they do not contain the actual video or audio data. Hence, when the location of the video clips used changes, it is possible that the project file can not access them anymore.
