Matinee track for 360 stereoscopic doesn't work

Hello. I’ve learned how use the stereopanoramic movie capture plugin and created short animation with matinee, wrapped all together in a blueprint with stereopano parameters and matinee actor as target ( but when i launch the SP.Panoramicmovie (frame here) command my frames are simply still, the animation doesn’t work. What ii’m doing in the wrong way ?
