Apple VideoToolbox

Supported hardware

Enabling support

If your computer is supported you will see one or more of the following video encoders added to the encoder control on the Video tab.

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

There are no advanced options available for VideoToolbox encoders.
