A tactical TV ad for Lidl to promote inexpensive running gear sold in their stores: A guy and girl are practicing on a treadmill. Gradually it becomes obvious that these two runners are generating the energy to the surrounding city. Integrated packshot with supers (the low prices) and a pay-off as VO: "Low price generator - Lidl"

We did not switch on/off any lights – the lights coming to life were completely created in the post. The overall goal was to create a phenomenon that looks real, but also has some magic. We shot hours of material with various exposures in Hong Kong. The plates were comped together with AE. The effect on the lights switching on was customized for each window.

The used techniques varied. Shot number three we used three separate passes – 25fps pass for the street, 12fps pass for the exterior walls and another exposure pass for the windows.

Sometimes just an area of the shot was manipulated by increasing (or decreasing) the exposure of it. For manipulating exposure we used three different techniques: using a plate where an f-stop was opened (or closed) and controlling the brightness with AE or in the color grading.

The grading process was heavy with four separate sessions – first to find the overall look and secondly balancing the created comps and emphasizing the increasing (or decreasing) light effect on each shot.

Interior was shot in Tallinn. Instead of using green screen the runners were rotoscoped for each shot as we wanted to avoid green spills on the reflections on the floor. The scenery outside the interior is a matte painting, hand crafted from the live plates. For the interior shots the increasing (or decreasing) the light level was done in-camera but controlled and balanced later in the post production to match perfectly the matte painting’s actions.
