Use the resize filter, set your compression, then save AVI.

It's going to look terrible.

The reason it's going to look terrible is because the source is only 320x240. There are no filters that can magically transform it to 1080p and make a better image. It's still going to look like 320x240, only bigger.

what video resoliuton is best to encode to 1080p There is no best per forum rule 12, and you shouldn't ask about it.

and what filter to use? Use whatever you think can improve the video. You haven't posted a sample, so there's no way to advise you.

That's 50% false ;)

The image can look better just because of a better scaler, to name one filter. It will not look like native 1080p I agree, but I did an experiment when I bought my BD player with some old VCDs I had, including an original one. The DVD player displayed it as a sort of "bigger VCD" with visible artifacts, while the BD player send it almost perfectly on the screen, just the resolution wasn't 1080p but sort of VGA like.

You can't perform magic, but you can improve LD videos. The things change dramatically when the video itself has problems (not due to format restriction), like youtube ones. These are almost hopeless, even for PAL/NTSC formats.
