2025: Organization of video mapping installation in honor of the 80th anniversary of Victory at the Moscow City Hall

In honor of the eightieth anniversary of Victory in the Great Patriotic War, the facade of the Moscow City Hall building became a canvas for a large-scale video jumping installation telling about the history of one family in the war years - about a girl whose father went to the front and mother worked in the rear, giving all her strength to the approach of Victory. The initiators of the project are the Moscow Government and the Mayor's Office, and the specialists of OTKRITIE, a multimedia integrator, were engaged in the development and technical implementation of this task. This was announced on June 9, 2025 by OTKRITIE.

Our project was intended not only to tell about the events of the Great Patriotic War, but to create deep emotional contact with the audience through modern technologies. Video mapping has become a suitable tool for us to revive archival materials, turning them into visual storytelling. We understood that we were working with a topic that concerns every family in Russia, and therefore approached the process with special responsibility. Close engagement with the Mayor's Office and the General Archive Office enabled us to access unique documents. emphasized Vladimir Rozin, CEO of OTKRITIE

To achieve maximum effect, the team carried out extensive preparatory work: several scenarios were developed, each of which was thoroughly tested for historical accuracy and emotional strength. Special attention was paid to voice-over - the voice was supposed not only to accompany the image, but to increase its impact. In addition, experts experimented with a color palette, editing pace and even sound design so that each frame worked on a common idea. This project became not just a technical task, but a real creative challenge that required the well-coordinated work of historians, designers, scriptwriters and sound engineers.

From the point of view of the technical component, the project also turned out to be large-scale. The installation involved 18 projectors distributed over two towers of Layer elements (96 sections), 9 devices on each, mounted at the desired height and angle.

4 stacks of projectors were engaged in image formation (each stack is a group of vertically arranged projectors that project the same image onto one section of the picture field in order to increase brightness). 2 stacks combined 3 projectors, and two more - 4 projectors. These devices provide a brightness of 40,000 lumens in nominal power, and each is capable of producing 4K resolution: 4096×2160 pixels. To overcome a significant distance from the racks to the building, interchangeable long-focus lenses were used. Such devices provide a good light flux range, which in this case was necessary. Another 2 stacks were formed from Christie Griffyn 4K50-RGB projectors, two each in the stack. These are more powerful devices that provide a luminous flux of 50,000 lumens at the same 4K resolution. These projectors were used in the central part of the composition, where picture quality, color and high detail are especially important.

As a result, the projection canvas had a final resolution of 5820×4096 pixels - almost 1.5 times wider than the standard 4K. However, the presence of powerful projectors is not enough to create a video mapping installation of this level.

The fact is that a building is not a flat object, and the peculiarities of its geometry can interfere with the formation of a coherent image, which viewers would perceive as a single whole. Any error in the form will lead to the decay of the projection and distortion of the picture, so for a high-quality demonstration of the content, we needed an accurate 3D model of the building. First, it was scanned using a laser scanner - this technology measures the surface with high accuracy, literally up to a millimeter, and as a result creates a "point cloud" - an array of coordinates describing the architecture. Further, our specialists manually finalized the resulting model - removed artifacts, filled in the gaps, added small architectural elements. The resulting 3D map was actively used in the development of content - we needed every line, light and shadow to get exactly in the right place. told Andrey Lokhonin, leading multimedia engineer of OTKRITIE

At the initial stage, test images were displayed on the building - grids, lines, geometric figures. This helped to understand whether the projectors were standing correctly, whether the boundaries of the images between them were the same, whether the image was leaving because of the tilt. A pixel map was created - a kind of "scheme" that shows how much of the overall picture falls on which projector. At first, such a map was made for each stack - so that several projectors layered images on top of each other. Then the stacks were brought together.

To implement the project, a certain level of technological expertise was needed, and the work took a little more than a month. The result of this great joint work was appreciated by hundreds of thousands of Muscovites and guests of the capital. reported by Vladimir Rozin

After the demonstration of the main story, the story on the facade continued: then the project of the Mayor of the capital "The Word of the Soldier of Victory" was shown: these are photographs of the participants in the Great Patriotic War living today in Moscow. All of them are over 95, and the oldest is 107 years old.
