NEW DENOISER BUG
The new Denoiser effect is really useful :) but it's still leaving a little first part of the clip with noise :(

I believe it's a spectral deNoiser, which - like the existing noise reduction effects - has a spectral decay rate. That means there is some amount of time for "learning" before the noise "decays" to the reduced amount.
Personally, I don't like the trend towards "big knobs" or single knob/slider plugins. Its fine to have that as the main interface, but Adobe needs to give us an advanced panel to allow those interested in tailoring the effect to their taste/need (as they do with the existing denoise [process]).
Ditto for the new de-Reverb effect; it needs more user interaction, the machine learning/AI isn't there yet.
