[MEncoder-users] Noise reduction and interlacing: (hq)denoise3d vs. nr

[Levente Novák]

What are the differences between denoise3d (or hqdn3d) and the nr lavc
denoise filter? Beside that the latter is faster, are both equally
appropriate for denoising interlaced content? I am asking this as it is
perfectly possible to put hqdn3d between il=d:d and il=i:i (so this is
interlaced-safe), but nr is a lavc option and it is not clear to me
whether it does or does not harm interlaced content.
