The following value types are supported (each option only accepts one value type):Ī number that can be written without a fractional or decimal component.Īn alphanumeric string of characters. If using HandBrake’s command line interface, use the -encopts parameter as follows: -encopts="option1=value1:option2=value2" If using HandBrake’s graphical interface, you can set the options in the Advanced Options field on the Video tab in the following format: option1=value1:option2=value2 Generally speaking, it is not recommended to change these parameters, as the built-in presets offer a good range of options for common uses. The AMD VCN hardware encoder has a limited set of advanced encoder options. To minimize this effect, disable any filters that you do not require. It is also common, particularly on lower-end or older hardware, for the CPU to be a bottleneck which will cause lower than expected performance. As such, it is normal to see high (or even 100%) CPU utilisation even when using VCN. These operations all happen in parallel as the job progresses. HandBrake supports the AMD VCN hardware encoder but does NOT support the hardware decoder. These are a good starting point for configuring HandBrake to use these encoders. The following presets are available under the ‘Hardware’ category in the presets menu: If your system is not supported, the option will be disabled. Support for the AMD VCN encoder is enabled in preferences on the video tab. Additionally, you must manually install the amf-amdgpu-pro package included in the download. Install using the amdgpu-pro-install script according to AMD’s installation guide. On Ubuntu Linux, AMD Radeon Software for Linux version 22.40 or later is required to use the VCN encoder. Hardware encoding via VCN might work on older series GPUs and older operating systems, but this is not officially supported.
