# VkVideoEncodeAV1SuperblockSizeFlagBitsKHR(3) Manual Page

## Name

VkVideoEncodeAV1SuperblockSizeFlagBitsKHR - Supported superblock sizes for AV1 video encode

## C Specification

Bits which may be set in VkVideoEncodeAV1CapabilitiesKHR::`superblockSizes`, indicating the superblock sizes supported by the implementation, are:

    // Provided by VK_KHR_video_encode_av1
    typedef enum VkVideoEncodeAV1SuperblockSizeFlagBitsKHR {
        VK_VIDEO_ENCODE_AV1_SUPERBLOCK_SIZE_64_BIT_KHR = 0x00000001,
        VK_VIDEO_ENCODE_AV1_SUPERBLOCK_SIZE_128_BIT_KHR = 0x00000002,
    } VkVideoEncodeAV1SuperblockSizeFlagBitsKHR;

## Description

- VK_VIDEO_ENCODE_AV1_SUPERBLOCK_SIZE_64_BIT_KHR specifies that a superblock size of 64x64 is supported.

- VK_VIDEO_ENCODE_AV1_SUPERBLOCK_SIZE_128_BIT_KHR specifies that a superblock size of 128x128 is supported.
