Hardware encoding via VideoToolbox *might* work on older series GPUs and older operating systems, but this is not officially supported. ## 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. - H.264 (VideoToolbox) - H.265 (VideoToolbox) Choice of the underlying hardware encoder (AMD VCE or Intel Quick Sync Video) is not available. The highest quality option will typically be chosen. ## 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.
