Uberto Alberti ~ Forgot to Bring Protection
There aren't many videos on Uberto Alberti's assassination. Mostly because you're only armed with the hidden blade and nothing else. What you can do is eliminate each guard/archer before the mission starts. I've had very different outcomes with how the guards are positioned each time. So it may be different with any of your playthroughs.
All you have to do is go to the area where the mission takes place. You don't have to be stealthy here. You can charge through every guard and take them all out. Or, you can silently take out the archers on the roof of the entire building.
Once the guards are eliminated, the archers on the left-most side (from where the mission starts) should disappear. On other attempts at this, sometimes guards on the ground or archers on the other side of the building would reappear, even after you kill them. This may depend on the proximity of the player to the specified areas for each enemy NPC.
I just thought this would make an interesting montage video of pre-mission blitzes.
Reacher did the preassassination mission on ulberto:

I generally dislike preassassinating, so I use it sparingly. Don't get me wrong though - I respect that different people will have different preferences in terms of style.
OH COME ON!!! 
Everyone keeps beating me to these things! haha. Well Ian, I only preassassinate when I want to be more Batman-like. Just thinking of it as a movie. The guards are in position. The target is comfortable and so sure he'll be safe. Once the Assassin shows up and no one is coming to their aid, he poops a little out of fear. 
It's even better when there is a chase sequence and every guard is on the ground the entire way. I did this in AC1 with Abul many times, and he always ran around and yelled "Guards! GUARDS! Where are my guards?!" At this point, I'd leap off of his fortress and assassinate him.
I used a preassassinate method on Francesco de' Pazzi today, actually. That one makes the most sense. He yells at his guards to kill you, yet there are only dead bodies on the roof. Then once Ezio says "No one's coming. It's only us now," he's telling the truth! 
I like pre assassinating when you arent meant to. Like my other video with Vieri, the dieing guard says Mario is overrun yet there is no one there. I didnt really show myself pre assassinating in the video though, so you can still make a video on how its done. I just showed the result, that you can stealth kill Uberto and get away with it without being seen afterwards

Hm, maybe I will make a How-to video...unless SOMEONE beats me to it. lol
I got past that stage again, lack of a replay feature isnt giving me motivation to start a fresh file and doing it myself so go for it
Well it'll probably be a long while before I can get anything like a capture card to record it, so there's no rush.
