GPS Teams Up With Channel 5

Gramercy Park Studios (GPS) has teamed up with Channel 5 to create a series of VFX-driven promos for the return of reality show Big Brother.

Featuring the show's presenters, Emma Willis and Rylan Clark-Neal, almost every element of the campaign was created in post production by GPS.

In both the 20" and 30" promos, Rylan is seen smashing a sledgehammer against an enormous mirror, shattering it into the form of the new Big Brother logo. The shards of glass then fly past the presenters and towards the screen, creating an unsettling but visually stunning 3D experience.

Richard Ireland, Managing Director of GPS, said: "It was a pleasure to work with Channel 5 and the team on this project. The promo really shows off the talent and facilities we have at Gramercy Park Studios. And being able to provide Offline (including on-set editing), VFX, CGI and Colour Grading all under one roof really showcased the benefits of our end-to-end offering in keeping the creative as the most important thing."

Mark Beardall, Head of 2D at GPS, created a pre-visualisation in Flame that proved invaluable in tackling Channel 5's intricate creative brief. He said: "Our initial contact with the Channel 5 team revealed ambitious plans, highlighting what a technical challenge it was going to be to achieve the colour-reverse mirror effect for the opening shot. With the help of the technical pre-visualisation, we came up with a plan to get exactly what we needed from the green screen shoot."

However, on-set production was complicated by the fact that Rylan and Emma weren’t available at the same time, so GPS editor, Vee Pinot, was on-set to edit and test the footage, ensuring it would work in post production.

To address the issue of designing shards created by Rylan’s hammer blow, GPS’s 2D and 3D departments worked in close partnership, turning to a combination of Flame and CG.

Matt Lowery, Head of 3D at GPS, said: "When it comes to moving thousands of pieces of CG geometry in any kind of realistic way, simulation is the way to go. We used a combination of RealFow, Maya and Bullet dynamics to achieve the final shattering simulation of over 4,500 separate pieces of geometry. The shattering of the logo was created using the same techniques, taking into account the look of the newly designed Big Brother eye, and blended into our final glass world. Once we had the glass and mirror shards moving how we wanted them, we added in some hand animated 'hero' shards, some finer glass particles, and started the lighting and rendering process."

Matt and the 3D team at GPS then created the transition glass shards that fly directly towards the viewers’ eyes, further intensifying the 3D feel of the entire spot whilst also presenting Channel 5's new branding.
