Supported Hardware and Configurations
- Nvidia GeForce GTX Pascal (1050+) and RTX Turing (1650+, 2060+) series GPU or better
- Nvidia Graphics Driver 418.81 or later
- Windows 10
- Experimental Linux support is available in HandBrake’s command line interface
Please note, these are not hard limits. Hardware encoding via Nvenc might work on older series GPUs and older operating systems, but this is not officially supported.
Support for the Nvidia Nvenc 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 Nvidia Nvenc 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:
From HandBrake’s graphical interface, set the options in the
Advanced Options field on the
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.
