Off topic, and this may be the stupidest thing I've ever said, but would just making a little box with two rca video inputes that combine together through a potentiometer and output to one rca work at all? The idea being that you could crossfade through video the same way you would through audio and get crazy weird signals. Or would that just explode my tv?

Yeah, its a dirty mixer lacking a TBC (Time Base Corrector) which means that the feed you are trying to mix together won't remain stable or consistent in color. If you want to see / build a really simple one google "karl klomp, dirty video mixer". I built one and while it is fun, some of the projectors I tried to use it with would just bluescreen in the middle of the "fade"

And a bit lighter and smaller than the V-1!

But yeah I got my fears confirmed that the Edirols are in fact the smallest proper video mixers

Thanks guys!

What it really lacks is a separate monitor output.

That being said, I packed it just wrong in a suitcase on a recent plane flight and it took a lot of damage. I had to replace all the knobs and the rotary switch and I'm waiting on a special order crossfader board from Japan. Having opened it up, I don't know how much smaller they could have gotten the thing, really, not without making it way more expensive.
