Pushing the envelope with 16K video

In 2018, I had a sudden urge to try something unique, something that had never been achieved before. Somehow, I landed on the idea of producing a short film on the highest resolution format technology would allow at the time. That format would be 16K utilizing a wide 2.76:1 aspect ratio at 15,985 x 5792 pixels. I wanted to see if it could be done and knew it would be a challenge since no 16K video camera actually existed.?

The 16K project would be titled,?"Prairie Wind"?and would feature dramatic storms over??the Great Plains of America.

I purchased two Canon 5Ds 50-megapixel DSLRS and two Sigma 35mm f/1.4 Art lenses that were manufactured in sequence for the best match possible. I then designed and built a custom-made mount to keep the two cameras perfectly aligned. The goal was to capture two side by side images and stitch them together so that I would end up with a 16K image.

Shooting with this rig required a lot of precision and speed. The settings on both cameras had to match, including exposure which changed from scene to scene. And, a 15-pound shot bag had to be attached to the rig to keep it steady in the wind. All of this while staring down the barrel of a tornado-warned supercell at times. It was fun.

In total, I shot about 50 sequences. The first step was to test each one for stitching. I ended up with 35 scenes that would stitch properly. During post-production, 12,000 images were combined to create one 15,985 x 5792 pixel image using a 2013 8-core Apple Mac Pro workstation. Each shot required a minimum of 5 days to prepare with the computer working around the clock. To keep the processors from overheating, the Mac was cooled by two large??external fans. Really, it was post-production that required the most time and patience during this project. This is where 16K video and history was made. Both Apple and Intel called me after I published “Prairie Wind” wanting to know how I did it. They said they wanted to test a new processor using 16K video. I can only guess this was related to the new Apple M1, an innovative?ARM-based systems-on-a-chip?(SoCs)?processor.

The primary thing that I learned during this project was that almost anything can be achieved when creativity and patience are combined.
