I am not sure if that's what you meant John,
but when you said "turn frame blending and to best quality" it seems you're referring to the layer switch and not the frame blending mode in the plugin.
turning on frame blending switch for the layer and using time warp effect will actually duplicate the frame blending which can cause unwanted/unnecessary results.
there is a built in frame blending option in the plugin itself (not the layer switch).
my apologies if I misunderstood your advice.
