HEVC/H.265 at a glance
HEVC/H.265
The Joint Collaborative Team on Video Coding developed HEVC through ITU-T VCEG and ISO MPEG, building on H.264 coding tools while introducing 64×64 coding tree units, advanced motion compensation, and scalable/multiview extensions.
KDC at a glance
KDC
Digital photography fragmented into many manufacturer-specific raw formats because camera makers optimized for their own sensors, metadata, and software ecosystems rather than for one shared public raw standard.

FAQs
Why convert HEVC/H.265 to KDC?
Convert to KDC when preserving Kodak-origin raw captures or maintaining compatibility with older Kodak photo libraries.
In most current pipelines it is a source or archival target rather than a preferred modern output.
What changes when converting HEVC/H.265 to KDC?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to KDC adds camera raw data. Moving to KDC removes HDR content. Moving to KDC removes streaming delivery.
What should I review after converting HEVC/H.265 to KDC?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
