Plus if the reviewer was only going to use SSIM to compare quality, he probably should have enabled -tune simm for x264. No mention of the resulting bitrates, unless I'm missing the obvious. It compares x264 CRF 10/16 with QuickSync QP 10/16.

Still, it was a delightful eye opener with my very first results using Handbrake QS. Things may have improved with these programs since then and, to be fair, I was using the original i7-2600K processor.

I should mention that I did play around with QuickSync a couple of years ago when it was only supported by a couple of software programs ( Splash Pro and another one), and found the results very poor with lots of artifacts. I haven't had any problem with auto cropping the last couple of builds but you can set it manually as well, or even leave the top and bottom black borders. In fact, I haven't used BD Rebuilder for over six months as I find the visual quality with QS to be virtually indistinguishable with casual viewing. My own informal tests at home tend to agree with these findings. Differences were very small, especially considering the huge time savings. I came across an article comparing the newer versions of QuicSync to X264 and itself at various bit rates. Much much faster than a couple of hours or more using BD Rebuilder.
Dvdfab quicksync movie#
With my Inspiron 17R SE with i7-3630QM it typically takes about 15 minutes (after dumping movie as ISO file on hard drive) to do a movie in QS which looks great on my big LCD.
Very few artifacts (in fact I can't see them). To be honest, if you use a QS with a QP setting of 22 or so, the results, to my eyes, are comparably to two-pass BD Rebuilder. Previously, I did many many blu-rays using BD Rebuilder (X264) with also great results. I've been using the nightly builds (Beta - all QS capable Handbrake's are here) for the last year or so with very good results. Is it possible to decode via Quicksync but encode using the x264 encoder? No - Quicksync uses its own encoder. Aside from a lack of QuickSync, Handbrake doesn't run on XP any more.
