Firstly let me say thanks for having developed this plugin. It is great to be able to use these codecs from within Adobe Premiere and therefore achieve better output files. This plugin is very encouraging.
Nothing is perfect though, so I found a bug - I think :
It seems that the "Constant Quantizer" setting does not work in HEVC mode.
I observe this problem while compressing videos with the "libx265" codec, using the "Constant Quantizer (CQP)" strategy. I tried to compress exactly the same video with various values around 20, such as 10, 16, 18, 20, 22 : to my surprise I end up with output files of pretty much the same size. I would expect a large change of size between 22 and 10 for example. I tried this with a couple of input videos (one just 30 seconds and the other one around 10 minutes) and come to the same conclusion.
I attach a log file corresponding to a voukoder session whereby I did part of this testing.
Thanks in advance for looking into this
