What is the best way to use FFMPEG to upconvert a 480p file (either native or converted from 480i using the Yadif filter) to 1080p with the NNEDI filter? Because I was thinking of using it for my projects, along with Valeyard's Motion-Adaptive script, both as necessary.

Isn't that kind of a stretch, going from 480p/i to 1080p? I mean, there's got to be some residual issues that would stick out, maybe I'm wrong too. LOL

No, I'm pretty sure NNEDI was designed for upscaling, unless I'm missing something.

For upscaling best to use TVIscale in Nuke. Major films are upscaled that way to 4K.

Thanks, but unless I can afford it, or else it has a free version which isn't too severely limited, I tend to shy away from proprietary software. Is there an alternative to Nuke which involves freeware or free-to-use shareware?

I've never used NNEDI but I know PDB uses it in some way for his upscale projects. Hopefully he can offer some advice at some point.

So basically, the idea would be to use NNEDI and AviSynth to upscale it by 4x in VirtualDub and then downscale it using a spacial scaling filter? This looks like a job for the new laptop I plan on getting at some point in the near future, but for now I think my Core i3 350M processor should do the job fine. Right?

Yep that's it and downscale with spline as spoRv suggested. You'll have to test whether your i3 can do that.
