x265 features/settings for converting VHS source?

[Nerva]

I have some DVD's that were copied from VHS tapes that I would like to re-encode with x265, and I was wondering if there are any special features that remove/improve artifacts associated with VHS? Mostly I'm referring to the "waviness" you see in VHS rips -- I definitely no expert, but I'm under the impression is has something to do with "timecode synchronization" not being used in the VHS > DVD process -- or I could be totally wrong. Anyways, I'm wondering if the problems can be corrected/reduced in the DVD > x265 conversion process.

That's really preprocessing stuff that would work with any codec, not anything specific to HEVC. Capturing from a high-quality VHS player or capture card that does reclocking of the vertical and horizontal blanking intervals (heck, I can't even remember the term of art of that once essential feature), and has a good 3D comb filter for luma/chroma separation helps a lot. Remember that the active 4:3 image area is really 704x480.

VHS is WAY analog, so the analog components you use to rip it matter at least as much as the software you use after. Back in the day, I swore by my Panasonic professional S-VHS deck, capturing from the S-Video output.
