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.
PFM Raw at a glance
PFM Raw
PFM persists from the era when HDR imaging, rendering research, and tone-mapping workflows needed straightforward file carriers for floating-point image data long before mainstream consumer HDR delivery formats matured.

FAQs
Why convert HEVC/H.265 to PFM Raw?
Convert to PFM raw when HDR rendering, tone-mapping, or scientific-imaging workflows need floating-point pixel values to survive intact between tools.
It is especially useful as an intermediate format for graphics research, physically based rendering, and analytical image-processing pipelines that operate on scene-referred data.
What changes when converting HEVC/H.265 to PFM Raw?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to PFM Raw removes streaming delivery.
What should I review after converting HEVC/H.265 to PFM Raw?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
