you can try it out i think via a demo on their site
i've only used it a bit (I find it easier to just use the CPU in vdub - hoping for a stand alone codec which supports cuda soon) but looking at the menu there is VBR h264 and then you set the min? bitrate, being 25kbps
I don't seen an option to do double pass, but the one they have is as good as x264 on the CPU it seems
cant set custom resolutions or crop or anything
