The -n 2 in lav2yuv was only a "simple" low pass noise filter.
lav2yuv als denoises the image and "sharpens" it so it is not that soft.
If you like it softer you should try set the sharpness to -S 100
(default is 125%) or maybe lower. Maybe you also want to have a larger
Denoiser threshold -t.

auf hoffentlich bald,
