I am having issues syncing with an off site dynamic cloth simulation program and think it might be because I render at 24 FPS.

changing to 30 FPS fixed it for the first 1800 frames but after that every second frame is once again out

I do not see this with the DAZ studio plugin so its a Carrara issue sending back as in the veiwer it is fine and nobody else seems to be experiencing it so maybe they all render at 30 FPS

UPDATE
