That is not the problem here.

First you save it to a lossless format, and then you do two-pass
encoding on the resulting file.

I never said you should do 2-pass on a TV source, just that
single-pass can't give very good results without very high bitrates.

Yes, denoise does lower picture quality plenty.  It improves
compressibility, but so does scaling-down the video to 1/8th it's
oroginal size...

Who said you need a new CPU?  They aren't all CPU-intensive options,
quite a lot of them don't affect CPU time at all, they just change how
lavc allocates the bits it has to work with.
