I was able to upload the video from within my Google account.
Uploading it from within Adrenalin did not work / I could not find the video.
Logging into Creator Studio did not show the video was uploaded from Adrenalin, however when I logging in ~ 2 hours later it showed 1 upload attempt had failed.
A second upload of the same recording from within Adrenalin had actually worked, but because the file size was large, it was showing as Waiting for Approval within Youtube Creator.
So it looks like it might be an idea to add a warning in Adrenalin about the Video File Size.
I just tried uploading smaller videos and it looks like they are uploading fine.
I will add an AMD Reporting Form asking to warn users about uploaded file size.
