Panasonic PT-RQ45K projectors just powered one of the largest projection mapping productions the company has ever deployed. As part of Hungary’s St Stephen’s Day celebrations, Panasonic Projector and Display technology illuminated some of Budapest’s most iconic landmarks, combining video mapping with lighting, lasers, drones, music and fireworks into a single city-scale spectacle.
A record-breaking deployment
The production used a record 67 new Panasonic PT-RQ45K 42,000-lumen 4K laser projectors, alongside 16 PT-RQ35K units, for a combined total of 83 projectors working in concert. Panasonic says the deployment represents the largest use of the PT-RQ45K worldwide to date, surpassing the model’s earlier high-profile appearances at events such as the Lille video mapping festival. At 42,000 lumens each, the Panasonic PT-RQ45K is built for exactly this kind of large-scale, high-brightness outdoor application, where ambient city lighting and long throw distances would overwhelm smaller projectors.
Running dozens of PT-RQ45K and PT-RQ35K units together also requires precise edge-blending and image-stacking across multiple building facades, so the finished result reads as one continuous canvas rather than a patchwork of individual projections.
The PT-RQ45K’s laser phosphor light source is rated for up to 20,000 hours of maintenance-free operation, which matters for a production like this one, where projectors run for extended rehearsal and show windows with no opportunity for lamp changes. Built-in geometric adjustment and multi-projector stacking tools, including Panasonic’s own alignment software, let riggers fine-tune overlap and color matching across dozens of units without recalibrating each projector by hand.
Illuminating the Parliament and the Danube
The projectors were used to illuminate both sides of the Hungarian Parliament Building, one of Budapest’s most photographed landmarks, along with the historic Széchenyi Chain Bridge and a run of buildings along the Pest side of the Danube. The riverside setting let the production play across water as well as stone, with the Parliament’s reflection doubling the visual impact for the crowds gathered along both banks.
Video mapping on a building the scale and architectural complexity of the Hungarian Parliament is a significant technical undertaking in its own right, since every spire, dome and window has to be accounted for in the mapping content so light lands exactly where it’s meant to.
Part of a bigger production
The projection mapping was just one layer of a broader audiovisual production for St Stephen’s Day, Hungary’s national holiday held every August 20. Panasonic’s projectors worked alongside a synchronized lighting rig, laser systems, a drone light show and a fireworks finale, all timed to a musical score. That combination is what turns a projection mapping display into the kind of nationally televised spectacle St Stephen’s Day has become known for in Hungary.
For readers who want to see how the Panasonic PT-RQ45K performs in a different large-format setting, the projector previously took center stage at the Lille video mapping festival, another showcase for the same flagship laser projector line. Both events underline how Panasonic is positioning the PT-RQ45K as its go-to solution for major public video mapping productions, rather than a projector built primarily for boardrooms or cinemas.
Large-scale projection mapping has become a fixture of national celebrations and cultural events across Europe, from New Year’s Eve shows to heritage anniversaries, and manufacturers increasingly treat these productions as proving grounds for their most powerful projectors. For Panasonic, Budapest adds another flagship reference alongside Lille, reinforcing the Panasonic PT-RQ45K’s position as a preferred choice for producers planning outdoor, building-scale visual spectacles rather than traditional indoor installations.
