I'm trying to export a clip that is only a few seconds in duration and it's as if the export function freezes up on me. I've selected the specific camera I want, the date and then found the clip where the time was at. The full clip appears to be 2h and 52 m long. I moved the slider to the start point and the end point. After I clicked the box with the arrow to export, I selected a hard drive on the computer and the convert/export screen just greys out and stays there.

In the record section of camera setup, I had "combine or cut video" set to 8 hours or 4GB. Maybe that is too large? I've trimmed it down to 1 hour. The computer doesn't seem to be overloaded, running 4-10% CPU during the whole process. The hard drive where the clip is stored and the hard drive I'm trying to export to are mostly empty. I'm running 5.6.7.3. I've also tried other cameras and it's the same thing, so it doesn't seem to be isolated to this one camera.
Any other ideas?
