context_page_description: "I Was Here" is a song recorded by American R&B recording artist Beyoncé from her fourth studio album, 4. It was written by Diane Warren, while production was handled by OneRepublic members Ryan Tedder and Brent Kutzle, alongside Kuk Harrell; while Beyoncé is credited on the vocal production. "I Was Here" is a reflective R&B ballad, in which Beyoncé vulnerably reviews her past, wanting to leave an impact on the world before her life comes to an end. Described as a "career song" by Warren, its development was motivated by the September 11 attacks in the United States.
  Following the release of 4, "I Was Here" charted at number 131 on the UK Singles Chart, 74 on the Swiss Singles Chart, and 44 on the South Korea Gaon International Singles Chart in early July 2011. Later, in 2012, the song also appeared on several charts internationally.
  A music video for the song was released on August 19, 2012 and it features Beyoncé performing the song live at the United Nations General Assembly while images of volunteers doing humanitarian work were projected on the screen behind her.
context_section_description: The video was filmed in front of a live audience at the United Nations General Assembly in New York on August 10, 2012. SuperUber worked on integration between animations and technology, the structure design and projection mapping that took over the General Assembly Hall after it was invited by Kenzo Digital. 10 20K HLM Barco projectors were placed and mapping was done using Pandora's widget designer and 5 Pandora's Dual Box servers. The final video had an 8856 x 1664 resolution and was split into 10 slices of 1080 x 1664 pixels, since each projector was turned on its side and the images were projected vertically in order to cover the whole structure. Two slices were fed into each system and SuperUber did the warping and edge blending inside Pandora. The screen which was used was over 12,000 square feet; Lucas Werthein, a representative for SuperUber commented that it was the largest indoor temporary screen that was a tilted compound curve adding that from an engineering standpoint, it is "extremely complex". It was custom-designed to mold to the inside of the General Assembly Hall. It spanned 68m X 15m and surrounded the audience with a 240 degree immersive projection. Ten synchronized and mapped projections covered the screen with 200,000 lumens, creating one continuous giant image. The screen which weighed 1000 pounds was sewn by forty five people. The whole structure, which was hanging off the UN ceiling weighed 6000 pounds. Werthein revealed, "In order to create the proper tension for the screen to hold its shape we had to weld permanent rigging points into the dome of the general assembly." Peter Kirn of Create Digital Motion wrote that the projection mapping was performed onto a fairly simple surface: "What makes the mapping so effective is the way in which it can fill the space, making those pictures immersive on a grand architectural scale. It makes the image a real volume in which the performance can take place." Russ Rive, SuperUber's director said, "It’s an ambitious project that has completely transformed an iconic location – seen as immutable and unchanging, with its goldplated panel and grand volume. By adding a virtual layer to it, we could digitally rebuild it, playing with the architectural elements, and therefore changing the notion of something static. The technology made the integration between animation and architecture. We used projectors to 'paint with light' the UN General Assembly’s Hall – a unique opportunity to transform such an emblematic place."
