Blackmagic URSA Cine 12K LF and Blackmagic PYXIS 6K digital film cameras were used for a new live action projection mapping film, “Texas Legacy in Lights”, created by Director John Franklin Rinehart of Austin Film Crew for the Gonzales Memorial Museum, producing a first of its kind narrative film that’s projected twice a day against the large exteriors of the museum.
Rinehart collaborated closely with DP Alex Walker for the project. “When we first conceived ‘Texas Legacy in Lights,’ the world’s first live action projection mapping film which covers the Texas Revolution of 1835, there were a lot of technical questions and challenges that came up right off the bat. Alex and I were pioneering something together, solving problems that didn’t yet have answers. There were moments on set where we’d look at the monitor and realize we were capturing something that had never existed before,” explained Rinehart.
The story now shared by Blackmagic Design reveals the challenges faced by the team and how Blackmagic cameras and software helped to solve the project’s main challenge, which was “ how to properly shoot for the architecture of the Gonzales Memorial Museum, which is 96 feet by 32 feet, approximately one and a half times the size of an IMAX screen.”
Rinehart detailed: “When you’re shooting for projection mapping, you’re shooting for the architecture of the building itself. We picked different points in the building’s architecture and different surfaces that would house various parts of the story, with the plan to blend the images together so that you could see the whole narrative on one giant canvas. In a way, we were shooting multiple films simultaneously and then compositing them into a single experience.”
Rinehart noted the PYXIS 6K was an ideal workhorse B camera, complementing the URSA Cine 12K LFs: “We loved the PYXIS’s form factor; it was very stripped down and nimble. We could rig it up in different locations, do overheads, and move it around without requiring a lot of crew.”
The URSA Cine 12K LFs’ sensor quality and high resolution capabilities were paramount, since the team had to shoot very wide to allow for the building’s architecture. “Having the ability to crop into the image became the backbone of our editing process. Since we had that extra resolution, we were able to be very creative in how we problem solved in post, in a way that no other cameras currently on the market would allow,” Rinehart said.
He explained, “For example, at times we would use a tight shot on the right of the building and a wide shot on the left, showing the exact moment from two different framings simultaneously. In traditional filmmaking, these are shots you would usually cut back and forth between. But in this case, we had both images playing simultaneously. The audience on the left side of the museum would have a different experience from those on the right.
“Since all the shots were shown at the same time on different parts of the building, we couldn’t cut back and forth like traditional filmmaking, so I couldn’t hide performances between different takes. It had to be a single continuous take that encompassed the entire performance. That meant shooting with coverage for tights and wides simultaneously, getting two different masters, two different tights, and an overall master of both characters in the frame, all at the same time.”
According to Rinehart, the cameras continued to prove themselves in post. “That’s when I was like, ‘Wow, this is really spectacular,’” he commented. “From a projection mapping perspective, having that latitude in post was crucial. We shot in Blackmagic RAW, which is second to none in terms of how lightweight it is and how well it works inside Resolve.”
“At one point, we were compositing the town of Gonzales burning, placing fire elements along the outside of the building and bending those to the architecture itself. We had 42 layers of 12K footage being pushed through the timeline, which is an extraordinary amount for any system to handle. The fact that it could actually play back in real time blew my mind. That’s not something you could do with any other codec or software combination unless you were running on a supercomputer or dealing with a ton of proxies,” Rinehart detailed.
“For the actual projection mapping work, we relied heavily on the crop and feathering features in Resolve,” he noted. “We could quickly blend images without having to grab a mask tool and manually work on them. Just being able to line up horizons quickly, that’s absolutely fantastic.”
“We mixed and mastered everything inside of the Fairlight page, including all the sound effects, dialogue, music, the whole mix. I was really thrilled with how it performed. Even when I was pulling in a lot of VST3 plugins, it didn’t bog down the system,” he said, adding: “We used the Fusion page as our primary VFX tool for particle effects and compositing. The node based workflow inside Fusion is really hard to beat.”
He explained, “We had to go onsite and perform a live grade of each element to ensure it had the correct color for its specific section of the building. Sometimes that required creating gradients because the stone was darker on the bottom and lighter at the top. So, we had to create graduated corrections, essentially blending two different color grades within a single image to account for the surface variations.
“This is where DaVinci Resolve’s ability to switch between node based grading and layer based editing really shone. We could create multiple correction layers with different masks and gradients, adjust them independently, and see the results in real time on the actual building. The fact that we were working with Blackmagic RAW meant we had all that color data to push and pull without breaking the image. We could be aggressive with the corrections because we knew it was all there in the RAW data.”
The team noted DaVinci Resolve Studio’s AI noise reduction tools were crucial for the scenes in low light. “We had a lot of nighttime and candlelit interior scenes, and the noise reduction tools handled it all beautifully without destroying detail. We could push those shots further than I’ve ever been able to before while keeping them clean. That kind of capability meant we weren’t limited creatively by technical constraints,” said Rinehart.
Rinehart concluded, “History can feel quite boring to many people, but we had the chance to make it come alive in a way that hadn’t been done before. These weren’t just historical figures, they were somebody’s grandmother, somebody’s child. The weight of that responsibility, to tell it right, to honor what they went through, that stayed with us through the entire production. And the story gets to live on for the next 15 years, for future generations.
“This film, beyond its technical breakthroughs, wouldn’t be anything to talk about if we hadn’t been able to properly tell the story and let people know it won’t be forgotten. The cameras, the resolution, the workflow, all of that served a larger purpose. We built something permanent for a community that deserves to have their story told on the same scale and ambition usually reserved for major cities, and that’s what makes all the technical problem solving worth it.”
