I have a 1 hour 20 minute 352 x 480 interlaced video. I tried Lanczos4Resize with this script however I noticed that it blurs too much or has noise on objects (I don't know how to describe what it was that I saw. It's still acceptable quality though):

Lanczos4Resize(704, 480, interlaced=true)
AddBorders(8, 0, 8, 0)

Nnedi3 does a good job with this script however it takes 11 hours:

nnedi3_rpow2(rfactor=2,cshift="spline36resize", fwidth=704, fheight=480)
AddBorders(8, 0, 8, 0)


Could somebody please advise of fast resizing scripts. It must take less than 4 hours.

That worked perfectly and decreased the time by more than 3x
Thank you very much.

You seem to know the right settings to get specific things done quickly. I was wondering if you might also know the answer to my question in this thread about black levels?:

Is Lanczos4Resize a good script for resizing? I'm resizing from 1280 x 720 to 624 x 352. From h.264 to xvid but I notice sometimes the picture gets blockly. Is there a better way to do this? I'd rather it be a sharp image rather than a smooth blurry one.
