Optus has undergone a complete brand transformation, and this shot was created to reveal the logo at the end of our brand launch video.
We shot the footage on Sony F65 on the Optus campus using a 12 meter dolly track. Our cinematographer Peter Beeh did an excellent job of planning the sun's position days in advance, so we were able to get a great shot with no time wasted.
I ingested the 4k raw footage and graded using DaVinci Resolve, then exported ready for tracking with Camera Tracker by The Foundry.
This process was more complicated than I had initially anticipated, due to the amount of glass and light reflections. Although our eyes can easily see where the rear glass wall is, the camera tracker sees the reflections of the side wall continuing back in space and produces inaccurate results in the track.
To correct this I created a series of mattes and temporarily graded the shot to remove any reflections.
The tracker now had plenty of solid grid-like lines from the concrete bevels and window frames to hang onto.
The next step was to fine tune the tracking data and remove all unwanted points that had drifted during analysis.
The 3D scene was created from this data and exported to Cinema 4D.
I had taken measurements of the building during the shoot and I was able to recreate it as a 3D object. The object was then aligned with the original footage as an overlay starting from the first frame. Scrubbing through the timeline I was able to see the 3D camera created from the tracking data was locked onto the footage quite well.
From here I created a camera projected material and mapped it to the 3D building. This gives the effect of the logo being stretched and skewed when viewed from the side, but aligns to form a perfectly scaled image as the camera moves along into the final position.
The 3D render was exported and composited back onto the original background footage. I then added the logo into the window reflection and stabilised a few kinks in the dolly move.
All there was left to do was add a final colour correct and a tiny extra flare around the edges and we were done!
