SpeedGrade DI at StreetDance 3D – Color in Three Dimensions

German postproduction house The Post Republic teamed up with Los Angeles-based ParadiseFX to realise the Vertigo Films feature Street Dance 3D. Both companies rely on SpeedGrade DI for 3D Stereo (3DS) quality control, 3DS rushes, 3DS adjustments and 3DS color grading.


Streetdance 3D is set in London and features some of Britain’s top dance talent. It tells the story of a a street dance crew in a bid to win the UK Street Dance championships, forced to join forces with a group of classical dancers causing sparks to fly and passions to rise.

The 47 day shoot on location in London is directed by Max Giwa and Dania Pasquini, with the creative visual supervison of the DOP Sam McCurdy and ParadiseFX’s stereographer Max Penner. Two RED camera rigs are in use for dolly and crane shots while steadycam and handheld shots are captured using paired SI2K cameras. All rigs are fully motorized, giving the stereographer the ability to adjust the interocular distance and convergence on the fly.


The captured material is sent twice a day to the digital lab for archiving, processing and quality control, while the cutting room gets HD rushes every day. “We are handling quite an amount of data coming from six cameras”, says Digital-Lab supervisor Andreas Schellenberg. “We are very satisfied with the stereo footage we receive daily. Paradise FX is doing a great job on precise sync, color and alignment of the paired cameras”.

“It is invaluable to have the D-lab regularly conform my sequences into a 3DS environment. This gives me the abilty to understand precisely how my 2D edit translates into the 3DS world” adds editor Tim Murrell.

The D-lab organizes all rushes and misfires are sorted and a neutral color correction is applied if necessary. The Quality Control is done by ParadiseFX’s Lead 3DS Artist Joe Van Dalsam on SpeedGrade DI. There he checks everything from color to stereo sync and alignment. The DP’s reference frames combined with the SpeedGrade OnSet .Look file help to establish the right look with a mouse click. Left from right color shifts, as well as vertical or horizontal geometry changes to bring objects closer or push them back can be easily applied with the difference matte function of SpeedGrade DI. The abilty to work directly with the RED .R3D and SI2K cineform RAW files offers a very fast and convenient way to bring the day’s shots onto a timeline and present it with realtime 2K stereo playback.

The directors and producers are very pleased with the 3DS experience and the efficiency of the process, which is more or less similar to a traditional film lab. However, instead of wearing white coats these lab rats wear stereo glasses and the usual smell of developer and fixer is replaced by the aroma of coffee and cookies.

    I took some H.264 footage from a pair of Canon 5DMK2’s into Vertigo last week. Joe loaded them up on the Iridas system and it played them, but not at full speed. Does Iridas have a problem with H.264?

    H.264 is processing intensive, but generally speaking no problems expected. Contact support to check this out.
