I've done a fair amount of capturing VHS video, losslessly, and then rendering it down afterwards. You can get rid of a fair amount of noise, using a median filter in AviSynth, after capturing multiple copies of the video. It's tedious, and every multiple has diminishing effects, but a median filter with five copies of the video, is going to look noticeably better than a single capture.
Not of personal results, no, I've got finals but not interstitials, and attempting to capture a clip resulted in finding out my VCR is having trouble reading tapes, which isn't entirely surprising. However, there are examples on the median() plugin forum posts, including the first set at: https://forum.doom9.org/showthread.php?t=170216 (Scroll down a bit for the pics).
