Videos beyond 4K will be delivered using the HEVC (H.265) video codec. Since support for HEVC playback only exists for newer generation devices and platforms, you’ll need to view them from specific hardware and software to view video qualities beyond 4K (e.g 5K, 6K, 8K). Note that we will only generate a 5-8K transcode if the creator uploaded it as an HDR video that has greater than 5K resolution.
