K25 in het kort
K25
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.
HEVC/H.265 in het kort
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.

Veelgestelde vragen
Why convert K25 to HEVC/H.265?
Convert to HEVC when the target environment can decode H.265 and the goal is to reduce bitrate for 4K, HDR, or long-form high-resolution video without giving up too much quality.
It is a strong target for premium streaming, UHD masters, efficient device delivery, and storage-sensitive archives that prioritize compression efficiency.
What changes when converting K25 to HEVC/H.265?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to HEVC/H.265 removes camera raw data. Moving to HEVC/H.265 adds HDR content. Moving to HEVC/H.265 adds streaming delivery.
What should I review after converting K25 to HEVC/H.265?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
