Is that right, or did I miss > something more obvious? Decode, denoise, reencode, decode, reencode. This is not a reasonable idea! Stick with two pass unless you're using a high bitrate and don't much care how big your final file is. yuvdenoise may or may not be more effective than hqdn3d but it is waaay slower. I suggest you just add hqdn3d to pass 2 and 3 of the script, after deinterlacing and before any crop or scale.
