Can't believe I'm the first to review such a great program here. The compression of this encoder is unreal and getting cleaner and faster as time goes on. By my own tests, 1.7 is about 33% faster than 1.6 which is amazing and hope further optimizations happen. x264 had to start somewhere and x265 will be no different.

Over the past month I have been encoding with it on high bitrate x264 files that I don't care to keep at their current file size, so I encode them with this with avisynth to retain most of the detail at a fraction of the size. I'm also doing this just to get a handle on this new HEVC beast.

All I need now is a HEVC TV Player...
