1)
DLPB never share anything, i won't enter in a debate here again, but i helped him, he never returned any help or hex value i needed, he does the same with lots of devel, too bad for users but reunion will never be supported by me and my mods, and as my mod needs lastest FFNx feature and DLPB don't use it...
long story short "never"
2)
fields animations are 30fps but fields animation while fmv are 15 fps so if fields is used as 15 fps with 30 fps fmv the animation is messed up.
that's why ATM trueOdin working on make the field's animation while fmv in 30 fps, so no speedup nor slowdows feeling when doing fields to fmv transition
so 30 fps fmv will look great with 30 fps fields aniation and it's only in this way i'll release the 30 fps fmv
long story short you won't be able to choose because 15 fps fmv will be useless and will only degrade the game comparing to 30 fps
