I just wanted to point out one case where composite is actually better from a laserdisc!

When the content is film with pulldown, sometimes a field is repeated for each phase of the dot crawl, which means if you average those fields together, you get a perfect, true s-video quality field with no dot crawl.

Of course, this one perfect field isn't so useful, however I had the idea that you use it as a guide somehow to reduce dot crawl in other fields and frames, or some kind of interpolation.

It seems it should work somehow, since you have this perfect reference to help you.

You can't use this idea with the s-video out, I think the attempts at filtering out the dot-crawl would destroy those two fields that were in opposite phases.

Also, when you average two fields, if the noise is normally distributed (a good assumption), the standard deviation of the noise is reduced by sqrt(2) or 41%.
