I wanted to export a video and after not finding any solution I looked it up on youtube. Apparently, when other people click on “Export” they see Details and an “Export” Button. But when I click on it, it only shows the Export Help and I can not change or click anything.
Either close the long list of presets by clicking on the heading triangles, or scroll down past the end using the scrollbar to the right of that panel.
Also, be wary of using Hardware Encoding. I you have problems with the resulting video it may be caused by this.
