+crf 28 in H265 is the equivalent of crf 23 in H264.

 The right compromise is to use libx265 for any videos that you want to keep around, but for videos that you’d prefer encoded quickly and will probably delete (say you want them for a single trip), hevc_videotoolbox is perfectly fine.  Output videos are still small enough, and the significantly faster encoding speeds mean that FFmpeg finishes far more quickly.
+If you’re going for quality/size, make sure you don’t enable any hardware acceleration.

 There is generallyt very little file size difference between fast, medium, and slow, but some encoding speed difference, so I just default to **-preset fast** for everything.

+===== Check =====
+To check to see that the file has been encoded correctly, use the **ffprobe** command like this:
+<code bash>
+ffprobe video-h265.mp4
+</code>
+The output will show that the video stream (probably stream#0) is encoded using hvec, i.e. H.265.
