Independent frame rate settings?

Is somehow possible to set different frame rate for video port and for preview port?

I would like to use preview port for motion detection at maximal frame rate (30fps) and at the same time save H264 from video port at e.g. 2-3 fps.

I don't believe so. Note that the camera is going to be running at the max speed required and I'm not sure we can bin frames, but I'll check tomorrow.

Not necessary max speed, enough will be also something like 20-25fps.

Sorry, but max speed I mean the highest speed you have requested. Which has actually made me think a bit more about this - the camera in video mode runs at 30-fps all the time, so we must be binning frames to get to the lower speed, either that or we request frames at the fps - I'll need to double check.
