DECE-Graphic

DECE-Graphic Strengths

  • Allowed the UltraViolet DRM ecosystem to easily distinguish structural UI/cover graphic assets from actual encrypted video tracks in a Common File Format container
Limitations
  • Completely obsolete since the 2019 shutdown of UltraViolet
  • Unnecessary abstraction, as the underlying files were just standard JPEGs or PNGs
  • Causes modern strict MIME-type validators to fail if they rely on the Content-Type header
Fuji-RAF

Fuji-RAF Strengths

  • Retains absolute maximum sensor data, enabling massive shadow recovery and highlight protection compared to compressed in-camera JPEGs
  • Stores proprietary Fujifilm Film Simulation metadata (like Classic Chrome or Acros), allowing editors to perfectly replicate in-camera aesthetics
  • Very distinct and reliable magic header makes programmatic file detection foolproof
Limitations
  • Proprietary format requires continuous updates to third-party software (like Lightroom) whenever Fujifilm releases a new camera
  • The X-Trans sensor matrix requires highly specialized demosaicing algorithms that are extremely computationally expensive, leading to slower import and rendering times
  • Completely unsupported in standard web browsers and basic operating system image viewers

When to choose which format

DECE-Graphic
Use DECE-Graphic when…
  • UltraViolet Movie Cover Art
  • Common File Format (CFF) Asset Manifests
  • Legacy DRM Ecosystems
Fuji-RAF
Use Fuji-RAF when…
  • Professional Digital Photography
  • Fujifilm X-Trans Sensor Image Archival
  • High Dynamic Range (HDR) Post-Processing
