Yes.

Input frame rate and output frame rate are independent.

Bino reads a video frame and looks at its time stamp, which is
usually defined by the input frame rate.

It then sets the output image to this input frame as soon as the next
display output frame has a time stamp >= the input frame time stamp.

The output image remains the same as long as no new input frame is set.
There is no interpolation in the time domain.
