K3 Focus Peaking During Video?

I can't see any normal AF or AF peaking during video recording . K-3 does only AF at some first seconds, then no more . When I'm moving to another subject , image is blurred . During video recording , I press AF button , the camera does focusing in and out few times in order to get a sharp image !

It will not be practical to use video clips with focusing in and out few times before stopping at sharp image .
Could any K-3 users please to confirm this ?

You can't really change this behavior without pdaf sensors on the sensor itself. But pentax could definitely have added an option to use full speed af rather than the slow implementation currently available during recording.

1-Focus Peaking is available before recording video only. Focus peaking goes away once you start recording
2-AF during video is slow and unpredictable, sometimes locking quickly, other times hunting before finding, and other times hunting and failing. In other words, unreliable and all but unusable.
