Best frame rate for VHS, where to set?
 

I have video captured from VHS (.avi, encoded with HuffYUV using what I believe are optimal capture settings as defined elsewhere on this forum) and now I'm working on encoding them with H.264/H.265 for sharing (don't worry, I'll save the originals for archival purposes.)

The video is, of course, at 29.97fps, and I'm using QTGMC to deinterlace it, which doubles the frame rate to 59.94 or whatever. My questions are:

- What frame rate should I encode this at? 29.97? or 30? I see no reason to go with ~60fps for the copies I am distributing, though if there's a good reason to I'm happy to change my mind.

- Where should I set this new frame rate? Should I do it in AVISynth using FPSDivisor=2? Or should I enforce the new framerate with my encoder (FFmpeg) where I can also specify a desired framerate?

Not sure if any of this makes a difference, but I'd love to know if something is more optimal than the other. Any tips are appreciated. Thanks in advance!

You want the QTGMC default, 59.94 fps.

It depends on use.

59.94 is not better, just different. It does remove some motion data, but not half. However, it also adds some artifacts, which become more visible at the higher fps, due to being interpolated to get from 29.97i to 59.94p.

There are even some odd side effects of interlace that can make some 59.94p bad to view, and selecting even/odd is the easy way to correct those. (The other way is advanced Avisynth for motion correction, and even then it can fail. I'm having this problem now with a 1970s VHS tape, where field are not overlapped perfectly, and jiggle. Not wiggle, not move, but jiggle.)
