After 11 months of development, the release of a tool for multi-threaded transcoding of video files from one format to another has been published - HandBrake 1.7.0. The program is available both in command line mode and as a GUI interface. The project code is written in C language (for Windows GUI implemented in .NET) and is distributed under the GPL license. Binary assemblies are prepared for Linux (Flatpak), macOS and Windows.
The program can transcode video from BluRay/DVD discs, copies of VIDEO_TS directories and any files whose format is supported by libavformat and libavcodec libraries from FFmpeg. At the output, files can be generated in containers such as WebM, MP4 and MKV, AV1, H.265, H.264, MPEG-2, VP8, VP9 and Theora codecs can be used for video encoding, AAC, MP3 for audio , AC-3, Flac, Vorbis and Opus. Additional features include: bitrate calculator, preview during encoding, image resizing and scaling, subtitle integrator, a wide range of conversion profiles for specific types of mobile devices.
In the new release:
- Added AV1 format encoders that use AMD VCN and NVIDIA NVENC engines for acceleration.
- Added support for multi-pass AV1 adaptive bitrate (ABR) encoding using the SVT-AV1 library
- Added hardware presets for the Apple VideoToolbox API. Updated Creator and Social presets.
- Added the ability to save metadata of the environment used for viewing.
- Added filters based on the Intel QSV (Quick Sync Video) API for format rotation and parsing.
- Performance optimization has been carried out on ARM64 and Apple Silicon systems.
- Improved HEVC decoding speed.
- The bwdif filter has been accelerated by 30%.
- AV1 encoding performance has increased up to 4 times due to the use of new assembly optimizations in SVT-AV1.
- The speed of video conversion has been increased by removing unnecessary copies of frames.
- Improved forwarding of Dolby Vision metadata about dynamic range of brightness.
- Added x265 encoder with support for 10-bit per color channel.
- Added Dolby Vision 8.4, 8.1, 7.6 and 5.0 profiles.
- Improved HDR10+ metadata forwarding when using x265 10-bit and SVT-AV1 encoders.
- Improved support for Intel QSV (Quick Sync Video) technology for hardware acceleration of video encoding and decoding on the Linux platform.
- When using NVENC technology, multi-pass encoding is disabled by default.
- Added support for the Meson assembly system.
