Framestore London Develops New System For Pepsi

Post Production
London, UK
Created a new proprietary crowd systemto fulfil the commercial’s massive scale.


Framestore has just completed VFX work on an epic Pepsi commercial that sees San Sebastian’s beach play host to a massive party, with DJ Calvin Harris at the helm. But the star power doesn’t end there; also at the party are world class footballers – Aguero, Drogba, Lampard, Messi, Torres and Wilshere – who indulge in a game of football above the crowd whilst supported by thousands of partygoers.
Framestore’s team of 20 VFX artists – spanning crowd specialists, Nuke compositors, roto artists, animators and technical directors – worked across the production for four months in order to deliver the commercial’s demanding and complex VFX whilst meeting all clients’ high expectations.
In the words of David Foulds, PepsiCo International’s Vice President Advertising: “To say that we are delighted with the final product would be an understatement.”

Framestore created a new proprietary crowd system in order to fulfil the commercial’s massive scale.

The system, developed by Diarmid Harrison-Murray and Martin Aufinger, was built in Houdini using mo-cap data captured at Framestore’s in-house motion capture facility. 

The crowd system is specifically designed to meet the needs of commercial projects. It allows a more efficient shot turnaround and gives the artist greater control over the crowds behaviour and look, down to details such as outfit, hairstyle, props and more. Using Houdini’s native renderer, Mantra, allowed artists to set up agents quicker and use more complex lighting techniques on selected parts of the crowd whilst still being able to render thousands of background people within the same setup.

Framestore’s new crowd system allows shots to be laid out quickly using an instancing approach, without having to simulate each agent separately. This meant VFX artists could show the director many iterations of the crowd layout in a relatively short amount of time.

Once the rough layout is approved, it is then possible to split off parts of the crowd that require bespoke behaviours, adding more layers of sophistication, in this case taking it to a level of detail where hands could dynamically grab footballers’ feet and even hold flashing camera phones. This custom-built system became invaluable for creating realistic looking scenes. 

As Aufinger explains: “The fun part of a crowd job is when you suddenly notice unusually strange, almost disturbing behaviour of one or two agents of a CG crowd. Luckily, we were easily able to quickly eliminate those offending agents!”

By merging the ability to layout a crowd quickly with a technique that enabled pinpointing of individual sections for more bespoke animation, the end results looked utterly authentic but were created with an efficiency that gave Framestore’s team more time to focus on improving more relevant parts of shots, thus freeing them from waiting for time consuming simulations. 

One key advantage of this approach over shooting live action crowd plates is that the lighting and atmosphere enveloping the crowd could be altered at any stage of the post process. As a result, this system has now become Framestore’s de-facto crowd system for commercial projects and several other departments have already shown great interest in using it. The modular nature of the system means that additional features can be easily added as future projects require. 

The project also gave Framestore’s 2D team – led by Chris Redding and Russell Dodgson – an interesting array of challenges. A small scale crew visited San Sebastian early in the process to capture very high resolution panoramic ‘dome’ images of the San Sebastian beach and to shoot the wide opening shot. These high-res location images were then projected onto an accurate topographical model of San Sebastian, extracted from Google Earth. This allowed the team to place a virtual camera anywhere on the beach and achieve realistic scale, perspective and defocus effects, which led to a huge degree of efficiency and consistency across the whole spot. 

Due to the limited availability of the hero footballers, the live action elements were spread across three shoots in three different countries, supervised by Chris Redding. Most of the live action crowd elements, body doubles, Calvin Harris and his DJ stage were shot over six days in Romania. The hero players, with the exception of Messi, were shot at Shepperton Studios in England, with Messi being filmed later in Barcelona.

In order to achieve the best result in matching live action elements and CG crowd, the animation team roto-animated the footballers’ performances to be able to relight them in 3D. This approach also provided the freedom to create more dramatic lighting effects and make sure the heroes of the commercial stood out from the supporting crowd.

Another team were tasked with developing the lazer letters that spell out the players’ names as they race across the crowd. After an initial brief from the director that referenced some prototype Japanese ionising lazers, a small team began testing several approaches. Using Houdini once again, the team quickly reached the aesthetic solution seen in the finished spot.

A further team, this time using Autodesk Maya, handled a wide range of additional duties. These included creating the upper two thirds of the main stage, including rigging, moving light units, background cars, additional volumetric lights and even full CG face replacements for some of the hero players. The Maya team was also responsible for creating fully CG digi doubles to replace almost all live action footballer body doubles in wider shots.
