So, almost a year and a half ago we encoded Skyfall with the new H265 format
by using the x264 successor, x265. We found that it was showing nice progress
in its development, but far from replacing the current x264 encoder.

The x265 encoder is still inferior, as expected, but that doesn't mean that it
won't produce adequate results in a few years. x264 wasn't perfect in the
beginning either, it took quite a few years, and currently we are just 2 years
into x265 development.

We chose a bitrate of 8mbit this time, as we believe this number should not
change with the adoption of x265 for regular releases (or rather the
CRF value that would produce this bitrate for this type of film as 2pass
should and will be abandoned by then). Even the higher bitrate of 10.5mbit
with x264 for our 1080p release was not enough to keep the finest details
and prevent the encode from showing blocking in dark scenes, although using
better encoding settings could have helped a little.
(A loss in quality you have to accept when racing other groups).
HD releases should not get smaller, but offer better quality at roughly the same size.

Since pictures say more than a thousand words, we have included 10 comparisons
between the source, this x265 encode and the previous x264 release. They have
been included in /Proof as lossless .png's renamed to .jpg to avoid site filters.
Beware, the second to last set contains spoilers.

This encode has of course 2.5mbit less video bitrate, but on the other
hand its supposed to offer higher efficiency with the given bits, so one would
expect this to look better than the x264 encode some day. Just not today.

Overall, x265 is far behind x264 in keeping the numerous fine details that the Blu-ray has,
which is a well made transfer from it's superb 70mm and 35mm master-negatives.
The fine grain is lost in virtually all frames, and blocking is visible
in every dark scene.

Our conclusion, grab the iNTERNAL (containing lossless video and audio tracks) we
released or watch the x264 version rather than this one, unless you want to test your
H265/HEVC playback capabilities. Finding a good decoder isn't as hard as it was the last
time. MPC-HC is still the leading software but VLC has recently also introduced
HEVC decoding.

Be patiend, it's still young. Or visit Millers planet if you aren't, just
don't forget to bring a towel.

Everyday takes figuring out how to live,
Sometimes it feels like a mistake,
Sometimes it's a winners parade,
Delight And Angers,
I guess thats the way it's supposed to be...
