I tried averaging VHS awhile ago, but just ended up with a slightly less noisy and slightly blurier image, so I was probably doing something wrong.

Interesting. Did you use a TBC? Uncorrected VHS sources contain a fair bit of jitter or wobble from one capture to the next. Multi-capture averaging on this kind of source probably would end up blurring edges. Fortunately, laserdisc sources are much more stable.

something like this:

Interleave(source1,source2,source3)
Clense(reduceflicker=false)
SelectEvery(3,1)

And for an average, I suppose you'd use something like this:

interleave(source1,source2,source3)
temporalsoften(1,255,255)
selectevery(3,1)

(or use the external plugin Average?)

Also, there may be some benefit to throwing a mocomped-denoised source into the mix as well.

Lots of options. I shall be following this thread with interest, not least because I may shortly be involved in a project to cap a rare (non-SW) Japanese LD for another member of these forums...
