The question is not about the FMV format.
The question is about that FCEU and Famtasia are two different emulators, and they emulate NES differently. They run different number of CPU cycles per frame, they probably give different cycle counts to different CPU instructions, they probably have differences in how a DMA transfer or RAM or VRAM access delays the CPU, differences in the sprite-0-hit flag, etc.
To emulate Famtasia in FCEU would require analyzing how exactly Famtasia emulates NES -- what are all the quirks in it.
Foremostly, it's definitely not worth the effort.
For one, it won't make a Famtasia movie into a FCEU movie. It will only make FCEU into a Famtasia, which is an useless goal: You should use Famtasia to play your FMV file.
In other words, there is no question at all in the file formats. Nesmock converts them to each others without problems.
The problem is in the emulation. The games act slightly differently in different emulators, which causes that the stream of button presses will eventually desync in the other emulator.
