It looks to me more like something blowing inside the engine compartment (part of fuel injection line or similar visible for whole remainder of flight) and engine is stopping afterward. Prop just isn't visible because it is in horizontal position.

....because you've got a roughly 22 to 1 glide ratio in something like an SGS 2-33 while its probably more like 10 to 1 in the Lancair, and maybe even less with parts falling off the front of the airplane.
Correction: 13:1 glide ratio for a Lancair, should've looked it up before I posted.

I've seen it elsewhere but its still an excellent demonstration of great airmanship. I liked how as soon as the failure occurred he immediately pitched up to gain extra altitude while he could. Not only that but he even managed to clear the runway and roll down the runway. It's almost as if he's done this many times before. He probably has, considering he's apparently a Reno air racer.

Perhaps that is the case, but it's also possible that he pitched up to lose speed and stop the propeller from windmilling, getting the vibration to stop sooner. With such a messed-up prop, you don't want the thing spinning too long or you risk tearing the engine from its mounts.
Well done to the pilot. Thanks for sharing the video.

How exactly does a prop just fail all of the sudden like that? I would think, i don't know for sure but I'm just "thinking out loud," that there would have been some noticeable defect during the walk around....? No? Yes? ...

An internal fatigue crack is invisible...only NDT can find it. Even a surface crack could be nearly impossible to see without something like dye penetrant. If the crack grows to critical length it will just come apart without warning.

Actually when you have an engine failure in a single engine plane the first thing you do is raise the nose to obtain the best glide angle speed then look for a place to land. That's why the nose pitched up slightly. This adjustment gives you the farthest gliding range.
I'd also worry about the stall speed going up slightly as you couldn't see from the cockpit exactly all the debris that was hanging out in the wind.
