How to batch convert to mp4 with arista-transcoder?

Question

I dont understand how to list valid preset names and select the Computer - H.264 preset available in the arista-gtk listing.

When I batch convert like arista-transcode -p "Computer - H.264" *.wmv the files are created as .webm, I need mp4.
