When I click on START button to encode my video file then nothing happens. I looked at the LOG tab and it says about some error. Here it is:


I googled for the problem and have found out that an x264.exe on my system is outdated. So I had downloaded a proper version
of this. I downloaded and can't really put to run this. Just some window pops up for a second and disseapears when I click on
x264.exe icon. I googled again specifically for this problem and have found out that x264.exe has to be run by command line.
I know that much that in order to bring on "black window" (excuse me, this the language I'm using, I don't know a lot about this stuff) I have to type cmd in SEARCH/RUN box. But what to type in there That's my question. I didn't find out that on Google.

Any help, please.
