What HandBrake does
HandBrake 1.11.2 is an open-source transcoder with x86-64 and ARM64 Windows builds, a macOS DMG, and an x86-64 Flatpak bundle. The Windows GUI also requires Microsoft.NET Desktop Runtime 10.0; download the matching x64 or Arm64 runtime through the publisher installation guide before preparing a disconnected machine. It reads many sources through its bundled libraries and writes its supported output containers/codecs; “many inputs” is not “almost any video,” and output choices vary by build, platform, encoder, source, and license.
HandBrake can read unencrypted DVD and Blu-ray sources. It does not include a mechanism to defeat copy protection, and this listing does not recommend circumvention. Damaged, protected, unusual, or unsupported discs and streams may fail. Subtitles, chapters, HDR/color metadata, variable frame rate, passthrough audio, and filters require source-specific validation.
Hardware encoders appear only with supported hardware and drivers. They can reduce encoding time or CPU load in some settings, but speed, quality, compression efficiency, power, and feature support differ from software encoders and across GPU generations. The current requirements page recommends 16 GB RAM for SD/HD and 32 GB or more for 4K. These are memory recommendations, separate from the space needed for source files, outputs and queues. They are not a measured performance promise for this release.
The publisher supplies SHA-256 values and detached signatures for release assets. No install, signature verification, protected-disc test, codec matrix, quality comparison, hardware benchmark, or metadata round trip was performed.
