Converting .bnp videos to .mp4 format.
Converting Sony Camcorder Video Data Files directly to MPEG-4 Videos (.bnp to .mp4 conversion) might perhaps be possible, but it will be quite challenging, since your options are limited to the original software bundled with your Sony Camcorder.
We are not aware of any third-party video editing software or (online) conversion tool capable of converting BNP to MP4.
The database currently does not contain any bnp software converter.
