Hi i have a mi SDI, I restore it and install rev. 5-1-191224

I hame some problem when put a camera on key as picture as picture, when i play with camera zoom, the image strobe and sometimes looks like robotic.

i make a new session 1080i 60 (as my camera SONY PXW-Z150 do), only connect the camera, pick this in program full screen move zoom and everything is ok.
go to M/E 1 , on the black background make a picture and picture composition with key 1 and camera 1, and the strobe appears..

someone knows what could be the problem?

thanks
(I test with other inputs and has the same problem)
