Since the dawn of cinema, the established film frame rate has been 24 frames per second (fps). However, Thomas Edison said the visual cortex needed at least 46 fps to avoid eye strain. To achieve this, and eliminate any eye strain or strobing, many modern 35 mm film projectors use two- and even three-bladed shutters—flashing each frame on the screen two or three times—to achieve 48 and 72 images per second to satisfy Mr. Edison’s recommendation.
Yet, despite all the technological advances over the past century, all those movies you’re watching in your fancy home theater—whether via DVD, Blu-ray, and even Ultra HD Blu-ray player—are being shown at that same 24 fps.
My latest pick for Movie of the Week is Billy Lynn’s Long Halftime Walk, not because it’s a great film—in fact, it’s kind of a mess of a story—but because it looks so frickin’ amazing that it’s the brain and eye candy your visual cortex has been craving!
Billy Lynn is so impressive because director Ang Lee used an extraordinary shooting style, filming at 4K resolution in stereoscopic 3-D at 120 fps—five times the traditional rate. This is the highest frame rate ever used on a film, eclipsing the 48 fps Peter Jackson employed for The Hobbit: An Unexpected Journey. This approach resulted in more than 540 terabytes of dailies with a final delivery file that was 84 TB.
But since only six theaters in the world—including just two in the US—could actually show the film in its full glory, you probably never saw it. And since 4K/120 exceeds the Ultra HD and HDMI 2.0 spec, Billy Lynn has been released to the home market in 4K at 60 fps, the highest resolution the format can support. This high frame rate requires the full 18 Gbps bandwidth, and will lay bare any shortcomings in your system’s signal chain. But for those lucky enough to experience it in its full 4K/60 glory, Billy Lynn looks absolutely stunning and unlike any movie you’ve seen before.
There’s hyper clarity and focus in every shot. Tight shots on actors’ faces reveal every thought, detail, and expression down to the thinnest individual strand of hair. Fabric in actors’ uniforms reveals texture and micro stitching detail, letting you see every nuance of the patches and medals, and even analyze the diamond pattern on rifle grips. Wide shots capture every actor, building, and set piece in razor-sharp focus. One of my favorite shots happens at 6 minutes 34 seconds, where you can read details on the gravestones many rows back in the cemetery, and when the camera pans over to the service, the image remains solid and focused.
From an audio standpoint, Billy Lynn includes an immersive Dolby Atmos mix that helps establish the ambience in different scenes. While the first half of the film is a bit restrained, the second half starting with the actual halftime show kicks into high gear, with the big battle scene in Chapter 11 being reference quality all the way.
Kaleidescape Strato owners need to be sure to download the HDR version of Billy Lynn’s Long Halftime Walk, since that’s the 60 fps version. While you might not love the movie, it’s sure to become your go-to video demo material when you want to impress your guests and demonstrate what the fuss about 4K HDR is all about!
