Setup for 80's grainy 576p

[Half_light Agent]

I want to rip a 1980's TV series from a 576p DVD boxset. It was shot on film with quite a bit of grain. Episodes run around 50m and are split into two .VOB files with a total up to 2GB per episode. There are about four episodes per 7,2GB DVD. I want to focus on a nice quality which keeps much of the grain and relatively small file sizes between 400 and 500MB. I have a 16GB Intel Core i5-8400 2,80GHz 64 bit Windows 10 with a 6GB 1660 TI. I'd like to keep encoding to at most 3 hours per episode.

Is there (a guide with) a recommended setup of software, codec and settings for this particular type of content?

If it's recorded on film that that means it's sped up. Slow it down. Some programs can do that
