I bolded the important parts for emphasis.
Properties of the .mkv file (and that's without any audio tracks added yet):
slower.mkv 9,10 GB (9.775.362.219 bytes)
So sure, the quality is top notch, it's hard to tell any differences with the original file grabbed straight from the source media which was about 19.4GB with an overall bitrate of 21.6 Mbps with a maximum bitrate peak of 28/0 Mbps but...
A such large file makes it unpractical for archiving purposes, let alone the fact it took no less than 77139 seconds to encode (1285 minutes or 21.43 hours, almost 22 hours!!!).
I was understanding that the main interest in x265/HEVC was to allow "high quality" content streaming/delivering/archiving with bitrate starved media/connections?
The very same movie in x264 with rather high-end settings weights only about 9.40GB once processed through x264 latest version... oh, and that's with a 2 hours DTS 5.1 track embedded within the matroska container versus here a 9.10 GB file *without* any audio tracks, just the video tracked processed through your settings.
What the hell?
Edit: Sorry my bad, I meant 9.40GB as x264 encode with audio track; not 6.40GB but with audio track still, versus a x265 encode of 9.10GB and no audio muxed yet. So my point stands still: x265 produced a file larger than x264 would have.
