Be Inspired by A Boulder Summer, Made on the Panasonic GH4

After watching Colorado branding and production agency Balcony Nine Media‘s A Boulder Summer, made for the 2014 TEDx Boulder conference, I found it difficult to stem the flow of superlatives. If I had to settle on just one, “inspirational” would be it.

Another praise word would be “educational,” because there is so much to learn from the two-person team who shot and edited A Boulder Summer over a period of 10 days – producer/director Katie Stjernholm and cinematographer/editor Jon Brumbaugh.

Brumbaugh, normally a Blackmagic Cinema Camera user, told me he chose the Panasonic GH4 for A Boulder Summer for the following reasons:

Size & weight – One scene required being suspended 70 feet down by rope while operating the GH4 on a 3-axis gimbal for up to 45 minutes. Another scene involved sprinting after a mountain biker while steadying the camera in the same gimbal.

Usable slow motion – Jon often uses slow motion for dramatic effect so appreciates the GH4's native slo-mo capability. He states that the GH4's 96 fps is usable for mid-close to big close-ups and that 48 fps and 60 fps are perfect for wide shots.

4K for post-production – The extra pixels that shooting in 4K grants are an asset when cropping and software stabilization are required.

Timelapses in-camera – Rendering Ultra HD time lapse sequences in-camera saved the crew valuable time during a very tight shoot.

The GH4 look and feel – A commenter at the movie's Vimeo page initially thought it had been shot on RED. Jon chose the GH4 after doing many camera tests that included the Blackmagic Cinema Camera.

“Although the Blackmagic delivers an incredibly cinematic image,” he says, “it was more important to have the flexibility and battery life of the GH4.”

“I was pleasantly surprised at the GH4 images' flexibility in post,” he admits. Jon chose the FJ SuperX 400 Film Convert for grading A Boulder Summer, and “it took the digital edge off and brought the footage to life.”
