HDR Video System Unveiled by University of Warwick

An obscene exageration of HDR

Although not available in a consumer product yet, research on High Dynamic Range (HDR) video coming out of the UK’s University of Warwick shows great promise for dramatic improvements in video image quality:

The new system captures 20 f-stops per frame of 1080p high-def video, at the NTSC standard 30 frames-per-second. In post-production, the optimum exposures can then be selected and/or combined for each shot, via a “tone-mapping” procedure. A process called Image-Based Lighting can also be utilized, in which computer-created objects can be added to real-world footage.

At this point the system captures a massive amount of data, 42GB per minute, for processing by post-production software.  A huge investment in signal processing hardware will be necessary before a technology like this will be able to make its way into your next family camcorder.

  • ergonomics
  • shortcuts in processing that involve tossing out 2/3rds of the lines resulting in diminished light sensitivity and increased color moire and noise.
  • a wobbling “Jello-world” produced by a top-to-bottom scanning sensor
  • awful audio
