<p>Hello everyone,<br /><br /> I'm new to this list and very interested in the "Slice decision options" of x265. The tests done so far show an expected behaviour of..<br /><br /> --open-gop<br /> which is enabled by default.<br /><br /> --keyint<br /> Setting this to a very high value, one which is higher than the duration of the longest shot, works fine.</p>
<p>I run into problems by setting up the parameters to find all slices from my reference (ground truth containing any flavour of slice one can imagine:). Increasing "<code class="descname">--scenecut</code>" beyond the default of 40 brought no significant gain of more detected slices. Also increasing "<code class="descname">--scenecut-bias</code>" (as I understood correctly) wasn't of that big impact in the tests I've done so far.</p>
<p>Are there some dependencies between parameters which are not that obvious here, at least to me? I also tried other parameters with no big impact.<br />I hoped to get a feeling how the parameters work in concert, but the "aggressive" placement of slices by changing "<code class="descname">--scenecut</code>" values could not be reproduced here. Am I doing anything wrong?</p>
<p>AIM:<br />- individual slice detection by threshold, not interval<br />- detect more false positives, than less</p>
<p>CSV:<br />- the csv log is used for comparing/counting the slices</p>
<p><br /></p>
<p>Any help, hint and reply on this is much appreciated.<br />I use a MSVC build for Win-x64 found here <a href="http://x265.ru/en/builds/">http://x265.ru/en/builds/</a> on a YUV input clip.</p>
