San Francisco Section Meeting:

Tuesday 2/19/13 – 6:30PM to 9:30PM

Last December Warner Bros. released ‘The Hobbit: An unexpected Journey’, and almost immediately reports of viewers being made sick from the 48 fps used were being reported in the media.  What followed seemed to be a debate on the use of ‘High Frame Rates’ by the movie industry, and Peter Jackson needing to defend its’ use for the movie.

While the Hobbit is the first major release to use this new technology, the topic of High Frame Rate (HFR) production was explored during the Monday symposium that kicked off last October’s SMPTE Technical Conference.  Those in attendance were treated to numerous presentations on the use of HFR spanning the topics of workflow to comparisons between differing frame rates. 

Our meeting this month continues this discussion of HFR and how subsequent processing has an impact on the presence of artifacts in the final presentation.  The structure of these artifacts is revealed by transforming the sequence of frames into the spatiotemporal frequency domain.  The visibility of these artifacts can then be determined through the application of a simplified model of human visual sensitivity to spatial and temporal frequencies.

Our presenter Andrew B. Watson, senior scientist for vision research at NASA Ames Research, will present a tool called ‘Window of Visibility’ which can be used to determine the lowest artifact-free frame rate.

 

This meeting is a must for those interested in HFR.
