AMD VCE Encoder
Supported Hardware and Configurations
- AMD Radeon RX 400 Series, Vega or better
- Windows 10
Please note, these are not hard limits and the feature may work on older cards and operating systems, but this is not officially supported.
Support for the VCE encoder can be enabled in preferences under the video tab. If your system is not supported, the option will be greyed out.
Take note that only the encode portion of the encode pipeline is done on the AMD hardware. Every stage prior and after in the pipeline including (decoding, filters, a/v sync, muxing etc.) all happen on the CPU. As a result, it is normal to have high, or 100% CPU utilisation during encodes.
It is common, particularly on lower end hardware that the CPU may be a bottleneck for the encoder. To minimise this effect, turn off any filters that you do not require.
Using the Advanced Options
VCE does have a limited set of advanced encoder options that can be used. Generally speaking is is not recommended to change these parameters. The built-in presets offer a good range of options.
From the command line, you can use the –encopts parameter as follows:
From the graphical user interface, just set the options in the dedicated options text box on the Video tab.
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 Takes a setting defined as s string. See comment for details.
