How to edit the DeNoise parameters for all cut parts of a clip?
If you need to apply the same effect to a whole clip, you can use Master Clip effects:

That way, you apply it to the file, and any clips from that file that you place into a sequence will have the same effect applied.  If you need to adjust it, you only need to do it once to the master effect.
