Microsoft submitted WMV9 to SMPTE for standardization in 2003, and the resulting VC-1 standard was approved in 2006. It was adopted alongside H.264 and MPEG-2 as a mandatory Blu-ray Disc video codec.
PFM Raw in het kort
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.

Veelgestelde vragen
Why convert VC-1 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 VC-1 to PFM Raw?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to PFM Raw adds HDR content.
What should I review after converting VC-1 to PFM Raw?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
