Well, if you need something immediately, there’s still the option of exporting your Shotcut project to a lossless file and using … Handbrake to denoise and create your final H.265 from the lossless file.

Tried this twice and was happy with the final Handbrake output

Slow (2 encodes), and FFV1/FLAC files are uuuuge, but it’s temporary and concede that having a lossless intermediate file is a good trade-off.
