As I mentioned since 11.32, the x264 export has been slow here due to running at single thread only. I compared its speed with x265 export and the x265 export was even faster than it slightly. 

The counter somehow stopped working in the exported version. I exported twice and both time the timer stopped somewhere in the video. Anyway, the timer worked in the preview so I took the time down. This is another issue. The video was exported with 11.32.
