Noise filters and interlaced DV source

[Irakli]

Hi, everyone

I am encoding several home videos in DV format to DVD. I want to apply some denoising filters using avisynth before encoding using HCenc.
So could you please advice me whether denoising filters work correctly with interlaced? Or should I use SeparateFields(), then <noise filter> and after that, Interleave()? Or, perhaps, deinterlace my source first (but I prefer to avoid this)?

Thanks for any help.
Regards,
Irakli.
