# VkVideoEncodeAV1QIndexKHR(3) Manual Page

## Name

VkVideoEncodeAV1QIndexKHR - Structure describing AV1 quantizer index values per prediction mode

## C Specification

The `VkVideoEncodeAV1QIndexKHR` structure is defined as:

    // Provided by VK_KHR_video_encode_av1
    typedef struct VkVideoEncodeAV1QIndexKHR {
        uint32_t    intraQIndex;
        uint32_t    predictiveQIndex;
        uint32_t    bipredictiveQIndex;
    } VkVideoEncodeAV1QIndexKHR;

## Members

- `intraQIndex` is the quantizer index to be used for frames encoded with VK_VIDEO_ENCODE_AV1_RATE_CONTROL_GROUP_INTRA_KHR.

- `predictiveQIndex` is the quantizer index to be used for frames encoded with VK_VIDEO_ENCODE_AV1_RATE_CONTROL_GROUP_PREDICTIVE_KHR.

- `bipredictiveQIndex` is the quantizer index to be used for frames encoded with VK_VIDEO_ENCODE_AV1_RATE_CONTROL_GROUP_BIPREDICTIVE_KHR.
