Tim grew up in the not-really-Southern college-town of Gainesville, Florida, in blissful humidity and an exploding punk scene. He began a career in filmmaking when he moved North to the kudzu-adorned college-town of Athens, Georgia and began work on a feature documentary DIRTY WORK with co-conspirator David Sampliner. Having not gone to film school, this became their film school. The film premiered at the Sundance Film Festival and garnered numerous awards at other festivals. 

Nackashi made an easy transition into music videos and commercials. Nackashi's video for OK Go's "WTF?" won a 2009 Webby Award. His Interactive 360º Panoramic video for Craig Wedren's "WAND" was nominated for a 2010 MTV Interactive O Award. His video for TV On The Radio's "Nine Types of Light" was nominated for a 2011 Grammy. And his video for Death Cab For Cutie's "You Are A Tourist" which was the first ever, live, one-take music video was nominated for a 2011 VMA. Since then Nackashi has directed videos for a long list of artists including Dua Lipa, Maroon 5, Neon Indian, Sean Paul, Jason Derulo, Pentatonix, Theophilus London, OneRepublic, Icona Pop, Electric Guest and many more. His short documentary "Through The Wall" won a 2016 IMAGEN Award.
