Converting .plist files to .mp4 format.
Converting macOS Property Lists directly to MPEG-4 Videos (.plist to .mp4 conversion) is not possible, since PLIST files do not contain any media data.
We are not aware of any available media editing software or (online) conversion tool capable of converting PLIST to MP4.
In a word, direct plist to mp4 conversion is not possible.
So don't expect any so-called plist to mp4 converter or plist to mp4 free online conversion tool available.
The database currently does not contain any plist software converter.
