Free space on the hard drive(s) ie the C: drive and the drive you are exporting to if there is a second drive and whether internal or a USB drive
Try the export again and note the Movie time in the export dialog that the export hangs at, what is on the timeline at that time plus/minus 10 seconds, eg change from video clip to image, transition, object with effect etc? A screen shot zoomed in on that section may help.
Thank you for the quick response. I will first revisit the space issue with an alternative drive. There are no messages associated with the hang up. Will be ntouch.
