<br>
The files are 1080p videos from youtube<br>
<br>
1) mortal engines movie trailer (<a href="http://youtube.com/watch?v=IRsFc2gguEg" rel="noreferrer" target="_blank">youtube.com/watch?v=IRsFc2gguEg</a>)<br>
2) polar movie trailer (<a href="http://youtube.com/watch?v=oMHwRal-AR8" rel="noreferrer" target="_blank">youtube.com/watch?v=oMHwRal-AR8</a>)<br>
3) solo movie trailer (<a href="http://youtube.com/watch?v=XRRNxIZfjHA" rel="noreferrer" target="_blank">youtube.com/watch?v=XRRNxIZfjHA</a>)<br>
<br>
All ratio are normalized taking x265 2.8+74-fd517ae68f93 as base<br>
x265 3.0 is version 3.0_RC+10-42b51d791a34<br>
<br>
x265 2.8 is from<br>

<br>
all videos were encoded with 1.77 aspect ratio, i.e 424x240,<br>
640x360,854x480 from the 1080p source videos<br>
<br>
--preset faster --crf 28 was used in all cases.<br>
