[HELP] How do I keep DVD rips small in size?

Most common artifacts are:

• macro blocking: you counter that with a deblocker, settings and filter
  
• ringing: for this you use de-ringer
  
• banding: for this you can use a debanding filter and ideally encode to 10bit
  
• aliasing: for this you might want to try a anti aliasing filter, be careful with these since they are often aiming for cartoon content
  

Depending on your source and your liking, you might also want to add a light degrain filter or which is often my preference use x265s/x264s internal noise filter.

If your source is interlaced you should deinterlace and if you source is telecined you should use an ivtc method.

Also remember: try to keep the filtering minimal, nearly all filters destroy information and most of the time its a 'give and take' so don't blindly filter.
Everyone you things that he found a perfect filter combination which is correct for all input is a fool.
