HandBrake version 1.11.0 includes two threading updates that boost video transcoding performance on high-core-count AMD Ryzen Threadripper processors by up to 215%. Contributed directly by AMD engineers, these fixes improve how the open-source software scales across hardware configurations with high thread counts.
Before this release, HandBrake struggled to scale beyond 64 logical processors, leaving computing cores underused on modern high-end desktop hardware. Low-resolution workloads were also split into jobs that were too small, producing excess scheduling overhead that caused CPU cycles to be spent on task coordination rather than transcoding. Tests on high-core-count configurations showed these issues could reduce transcoding rates by as much as 60%.

On the 64-core Ryzen Threadripper 7980X with 128GB of DDR5-5600 memory, transcoding speeds increased by up to 215% depending on the codec and resolution. The largest gains occurred during 720p H.264 transcoding, followed by a 203% speedup in 8K HEVC 8-bit workloads.
The 96-core Ryzen Threadripper PRO 9995WX workstation chip also demonstrated clear speedups, checking in at up to 181% faster transcoding in identical tests. High-resolution workloads like 8K HEVC 10-bit transcoding saw speedups of 145%, while 1080p HEVC 10-bit transcodes ran 91% faster. The Zen 5-based Threadripper PRO 9995WX runs on a default TDP of 350W and supports up to 192 threads.
These updates are now integrated directly into the main HandBrake branch, meaning professionals can benefit immediately by updating the application without changing their workflow steps. For developers running intensive multi-threaded code, workstation packages like the AMD Ryzen AI Halo Developer Platform offer similar high-core-count scaling capabilities.
The HandBrake 1.11.0 update is now available for download on the official project release page.
