1st movie clip!

thought I’d cracked it 1st I2V clip was 6 sec long, 12 FPS … ran it through my 2nd w/f (ReActor>video combine), set to 12 FPS… absolutely perfect output 2nd I2V clip was 6 sec long, 12 FPS … ran it through my 2nd w/f (ReActor>video combine), set to 12 FPS… perfect face swap but misses frames about 3 secs in and jumps… tried adjusting FPS but makes not difference other than to slow down or speed up clip.. so i get the faceswap but loose the smooth motion … grrrr Makes no sense to me Lost again
