Beck is playing the 2014 Coachella Festival, performing on the main Coachella stage on the Sunday night. This was the first weekend. If you're looking at video clips, the first weekend, Beck wore a red shirt (second weekend, black and white stripes).
As Coachella does, weekend one was webcast live via Youtube, and Beck's set was one of the artists streamed. However, the webcast does not get archived (and someone who ripped it and uploaded it, but it was removed by Coachella). I had embedded that video here, but it's no good now. Hopefully it can resurface! There are though some audience-shot videos on Youtube.
Beck also went a very tiny little bit over time, and since Coachella is heavy on a schedule, they ended up cutting the power so his audience couldn't hear him for the last minute or so of 'Where It's At.' However, this didn't effect the web stream (or likely the band on stage), and they did play it out, just albeit to a bunch of confused audience members.
