I have seen those basketballs transitions somewhere else... I think it was on Digital Hot Pancakes, or something like that...
I think i could do that using a mix of Photoshop and After Effects, but honestly, i dont know how long i would take...probably a some weeks, since i can only edit videos on the weekends...
But if you break down the video, the elements he used were actually pretty basic. I mean, for example on 00:15, he simply made a mask on the video and moved it around, and the background seems somewhat pre-made (Except the bird logo)... That doesn't take more than 5-10 minutes to do it... At 00:29, he just made the 2 pictures move forward on the Z axis, and he added some elements to the BG...No more than 8-14 minutes... If you really think, the effects were pretty easy, and he also used lots of royalty-free clips (The basketballs, etc...) I don't think you should take more than 12 days to do it if you worked 1-2 hours everyday...
