Windows Driver Kit DDI reference (ne-d3d12umddi-d3d12ddi_video_encoder_motion_estimation_precision_mode_0080)

Description

The D3D12DDI_VIDEO_ENCODER_MOTION_ESTIMATION_PRECISION_MODE_0080 enumeration lists the possible motion estimation precision modes.

Constants

`D3D12DDI_VIDEO_ENCODER_MOTION_ESTIMATION_PRECISION_MODE_0080_MAXIMUM`

Indicates no limit in the precision for motion estimation vectors, thus allowing the maximum precision supported by the driver.

`D3D12DDI_VIDEO_ENCODER_MOTION_ESTIMATION_PRECISION_MODE_0080_FULL_PIXEL`

Indicates that the precision for motion estimation vectors has to be at most full-pixel.

`D3D12DDI_VIDEO_ENCODER_MOTION_ESTIMATION_PRECISION_MODE_0080_HALF_PIXEL`

Indicates that the precision for motion estimation vectors has to be at most half-pixel.

`D3D12DDI_VIDEO_ENCODER_MOTION_ESTIMATION_PRECISION_MODE_0080_QUARTER_PIXEL`

Indicates that the precision for motion estimation vectors has to be at most quarter-pixel.

`D3D12DDI_VIDEO_ENCODER_MOTION_ESTIMATION_PRECISION_MODE_0095_EIGHTH_PIXEL`

Indicates that the precision for motion estimation vectors has to be at most eighth-pixel. Added in Windows 11, version 24H2 (WDDM 3.2).

Remarks

See D3D12 video encoding for general information.
