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.

Yeah, my video player has a built in TBC, which I think is only a line based unit and not a full frame jobbie as I'd like.
The tape I was trying to preserve is pretty fecked and the capture device was my DVD recorder, so probably not the best setup for testing the averaging method. I found I got better results from capturing once and running a noise filter over the MPG2. A better VRC/TBC/Capture setup and using a better CODEC would probably get better results than what I was geting.

something like this:

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

Yep, this was the script that I used. Didn't know about the 25,2 bit though, will have to give that a try once I get a better capture device.

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

Sorry, didn't understand that bit at all. Umm, whats a mocomped-denoiser?

WXM: thanks for posting that 'before and after' pic. Wow, that's imporessive stuff! You not only removed noise but it looks like the colours are more vibrant and stable and even and the contrast is much better. I am definitely going to have to play around with this a bit more.
