AMD VCE

Supported hardware

  • AMD Radeon RX 400, 500, Vega/II, Navi series GPU or better
  • 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.

Enabling support

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.

Performance

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.

Advanced options

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:

--encopts="option1=value1:option2=value2"

From HandBrake’s graphical interface, set the options in the Advanced Options field on the Video tab:

option1=value1:option2=value2

Option value types

The following value types are supported (each option only accepts one value type):

  • integer
    A number that can be written without a fractional or decimal component.

  • boolean
    0 means off (or disabled).
    1 means on (or enabled).

  • string
    An alphanumeric string of characters. See the option’s comments for acceptable values.
