I just try to test version 1.2 with Premiere CC2018.
Unfortunaly, it crashes when exporting to Nvidia H264 or H264.
With same parameters, no problem with version 1.1.3
Clip is AVCHD /H264 50p
Export to H264/H265 with all défaults, except :
variable bit rate 28-34 Mbits/s, audio AC3
Gop size 30
Ref Frames 2
I have not seen any différences in voukoder log files.
Thank you for your job
