Why convert ORF to HDR
02
Acceptance by downstream tools
HDR is the format most receiving systems expect for this kind of content. Converting upstream avoids the rejection and silent re-encoding that often happen when ORF reaches an unprepared pipeline.
03
Portable, predictable file format
HDR is well documented and decodable by long-lived tooling, which matters for archives, deliverables, and any file that needs to outlive the software that created it.
