OBS Studio 29 Beta 1 has officially been released and introduces AV1 encoding support for Intel & AMD GPUs.

OBS Studio opens up 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 GeForce RTX 40 series Ada Lovelace graphics cards but is branching out to offer further 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 the RDNA 3 architecture, and Intel HEVC encoding support.
