 For example, to convert a file to H.265/HEVC with GPU acceleration and AAC audio, plus scale it down to 480p, you would normally have to run a command like:
 ```sh
-ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i test.mp4 -vf scale=-1:480 -c:v hevc_nvenc -preset fast -c:a aac -c:s copy -map 0 out.mp4

 ### Hardware Acceleration
-If your `ffmpeg` [supports it](https://trac.ffmpeg.org/wiki/HWAccelIntro#CUDANVENCNVDEC), you can use NVIDIA GPU hardware acceleration to speed up the conversion. You can see the supported codecs for decoding & encoding for each GPU [here](https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new).
+
+Your `ffmpeg` must support the hardware acceleration you want to use. You can check this with `ffmpeg -hwaccels`. If you see `cuda` or `videotoolbox`, then you can use the hardware acceleration below.
+
+Using this can speed up the conversion process significantly!

+If your `ffmpeg` [supports it](https://trac.ffmpeg.org/wiki/HWAccelIntro#VideoToolbox) and you are using a Mac with Apple Silicon, you can use hardware acceleration for encoding by adding `--hardware-apple` or `--hw-apple` to the `manage-media convert` command.
