Converting .mp4 videos to .fbr format.
As far as we know, converting MPEG-4 Videos directly to FlashBack Screen Recordings (.mp4 to .fbr conversion) is not possible.
FBR recordings are generated by the BB FlashBack software, which then can be exported to more common video formats (AVI, WMV etc.). It appears that this doesn't work the other way round.
We are not aware of any video editing program or (online) conversion tool capable of converting .mp4 to .fbr.
