According to the uploader of the video in their reply to my comment:
Only simple deinterlacing removes half of the frames. QTGMC in AVISYNTH was used because it does an excellent job without throwing away every other half frame. A variety of deinterlacers were auditioned to pick the best. Bobbing interpolates every half frame to create 60fps, and creates jitter in fine detail, so it isn’t artifact free. The laser disc source had a problem with a number of sections where some half frames had sections with lines displaced. This also was in a tape made from a broadcast, so it is probably a problem in the master tape. This required extensive frame by frame editing. The conversion needed weeks of work to remove all of the problems, so it will not be redone. I have gone back and redone a handful of my early restorations, but this was a more recent one done with the best available software. The pros may have a deinterlacer/bobber which can restore the SD TV illusion of smoothness without jitter, but I don’t know if it it exists. The only way to get that may be to watch the laser disk on an old SD TV, but it will still have the displaced lines. Digitization of SD TV broadcasts also rotates fast moving objects because it is converting scanned motion into instantaneous images. Restoration/digitization is always a compromise. Sorry, but maybe someone else will do what you want. You should also know that YouTube further highly compresses the original submitted video which degrades what you see.
