Re-ran the rest using a smaller raw. Files are still quite large though.. The raw I used was a sample file used to demo 4k TVs. You can get it here:http://uhdsample.com/39-download-panaso ... video.html
Handbrake was configured using a modified 1080p30 preset, meaning the encodes would resize the 4k original down to 1080P. Resulting files would be much too large otherwise. I set everything to use Constant Quality 22QP, framerate fixed to same as source, with all filters off, audio track completely ignored (so the bitrate of the resulting file is all video).
So keeping the same settings and only changing the encoder I added each one as a new batch job then ran everything. The encode times are basically from taking the very first and very last timestamp in the log file. Codecs used: x264 8-bit and 10-bit encoder level 5.0, x265 8-bit and 10bit, NVENC h264, NVENC h265, QSV h264, QSV h265. I didn't bother testing 10-bit QSV or 12-bit x265.
