I have attempted to make changes based off several "fixes" that worked for other users and they have been no assistance to me. I believe I have version 6.20 to the best of my knowledge. I have attempted to export both as a youtube video and as just a video file. Have changed the video quality and compression ratio. Still nothing it gets to 67.5% and just continues to cycle but go nowhere. I have attempted this at 5 times now after all the adjustments. Please Help.
