Apple VideoToolbox
|
|
==================
|
|
|
|
## Supported hardware
|
|
|
|
- Most 2015 and later Macs
|
|
|
|
Please note, these are not hard limits. 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 QuickSync 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.
