How long is your video? Video uploaded from Premiere Elements to YouTube is limited to 10 minutes.
Are you able to output a video using Export & Share/Quick Export?
What is the format and resolution of the video you are building your project from and what camcorder did it come from?
Video is 5:39 long....
Yes - I can export okay
Format is 1280 x 720 30fps.. From an iPhone 6
This was just a quick video I did at a live event. But I've had this issue with everything I try to share to YouTube from Premiere. It always stops at 38% upload and locks the entire machine. I need to force power off and reboot to get it back.
Sharing directly to YouTube can be iffy, unfortunately. YouTube seems to change the rules monthly.
Adobe has tried to set the program to automatically update to match Web Services, but it's still not as clean a hookup as it should be.
But at least if you can output a Quick Export you have a workaround: You can manually load the Quick Export video to YouTube using your browser and YouTube's tools.
