Do you believe the 120 fps version of Ang Lee's film really uses a 216 degree virtual shutter? Some sites are saying Ang Lee's film, Billy Lynn's Long Halftime walk (which was captured with a 360 degree/open shutter) uses a 216 degree virtual square shutter for the 120 fps version of the film. eg. Ang Lee Shows the Future of Cinema Display (Updated) I can see how it would easily work and be true for the 24 fps version to have a 216 degree shutter (since each "open shutter" frame of the original 120 fps recording=one 72 degree 'slice' of a 24 fps version (120/24=5. 360 degrees/5=72 degrees). So 3 original frames from the original 120 fps version blended=one 216 degree frame for the 24 fps version). Also note that "TruMotion" in the article above is spelt wrong and it's (RealD's) "True Motion". On the RealD site, which gives some explanation of how it's True Motion works, nowhere does it mention that 'True Motion' uses any motion interpolation/motion compensation. True Motion just seems to work using ways already likely being done by others (eg. Pickfair institute/Douglas Trumbull), ie. combining frames from a high fps source (eg 120 fps) and allowing a certain weighting to each frame (eg. for a lower fps version). So surely it's the lower fps versions of the film that may use a 216 degree virtual shutter (eg. the 24 fps version should be able to use it quite accurately), not the 120 fps version?
