I earlier saved about 7 videos as MP4s on to a hard drive from Adobe Elements 2018. I then went back and put all of those MP4 videos back into one video, and tried to save them all as just one video, which is about 33 minutes long. I tried about 4 different times, and each time, there would be "Export Error" at the very end of the export procedure. I tried saving it as a smaller resolution, but still same thing. Not sure why it goes for an hour, to the very end, and THEN gives "Export Error". Is it too long, too big? Not sure. Any ideas?
