Hey there, we did all the videos ourselves. We created most of the graphics in Photoshop and animated them in After Effects, we recorded the voiceover in Audacity and did the final audio with music in garageband. Oh and we purchased the audio loop from audiojungle.com. Cheap but they have some decent stuff, you just have to find it ;) Hope that helps!
I was surprised to see "Go fuck yourself" on the video (0:39). Was that a mistake or a conscious decision? Otherwise, it's a very slick professional video.
