How to mosaic what is reflected in the screen

Question

Please tell me how to do mosaic processing for things that have been reflected in the screen

Answer

If there is little movement, specify the range with the power window on the color page

If there is movement, specify the range with the tracker on the color page

I think that it is better to apply the blur (mosaic) of Resolve FX blur from OpenFX to the nodes that specify these ranges.
