I recently had to replace my computer. Now, when I process a video, a thumbnail is not displayed, even when I add one manually. The video plays fine. Just no thumbnail. I've compared the diagnostic for this video with previous videos and there are no differences. Ideas? I'm using Camtasia 9.
I'm hosting them on Udemy. I'm on my second course there and this is the first time this has happened. If I upload them to screencast, the thumbnail I added is displayed. When I don't add one, a random thumbnail is displayed.
