It's just the matter of adding couple lines of code, something like
this:

instead of

  		if (_framecount == 0)
			compType = 2;
		else
			compType = 3;

write

		if (_framecount % 120 == 0)
			compType = 2;
		else
			compType = 3;

That will make a keyframe each 120 frames. compType 2 is a keyframe and
compType 3 is a XOR frame.
