OBS Studio 29 Beta 1 is officially released and introduces AV1 encoding support for Intel and AMD GPUs.
OBS Studio opens AV1 encoding support for Intel and AMD after NVIDIA received support earlier this month
OBS Studio previously introduced AV1 encoding support for NVIDIA and the new Ada Lovelace GeForce RTX 40 series graphics cards, but is branching out to offer additional support for NVIDIA’s competition. The new OBS Studio 29 Beta 1 will support the same encoding, but this time for AMD’s Radeon RX 7000 series, also known as RDNA 3 architecture, and Intel HEVC encoding support.
The official release notes are below and on the OBS project GitHub page. The new update supports macOS, Windows, and Linux.
