- AMD Radeon RX 400, 500, Vega/II, Navi series GPU or better
- Ubuntu Linux 18.04.3 or later, Windows 10
Please note, these are not hard limits. Hardware encoding via VCE might work on older series GPUs and older operating systems, but this is not officially supported.
On Ubuntu Linux, AMD Radeon Software for Linux version 19.20 or later is required to use the VCE encoder. Install using the
amdgpu-pro-install script according to AMD’s installation guide. Additionally, you must manually install the
amf-amdgpu-pro package included in the download.
Support for the AMD VCE encoder is enabled in preferences on the video tab. If your system is not supported, the option will be disabled.
Only video encoding is performed by the hardware encoder. Every stage prior to and after video encoding including decoding, filters, audio/video sync, audio encoding, muxing, etc., is performed by the CPU. As a result, it is normal to have high (even 100%) CPU utilisation during encodes.
It is common, particularly on lower-end hardware, for the CPU to be a bottleneck for the hardware video encoder. To minimize this effect, disable any filters that you do not require.
The AMD VCE hardware encoder has a limited set of advanced encoder options. Generally speaking, it is not recommended to change these parameters, as the built-in presets offer a good range of options for common uses.
From HandBrake’s command line interface, use the
--encopts parameter as follows:

Option value types
The following value types are supported (each option only accepts one value type):
A number that can be written without a fractional or decimal component.
0 means off (or disabled).
1 means on (or enabled).
An alphanumeric string of characters. See the option’s comments for acceptable values.
