What version of Premiere Elements are you using and on what computer operating system is it running?
Then the usual questions
1. Is the Facebook upload from within the program the only export with a blurred outcome?
2. What are the properties of your source media? What project preset is being set to match the properties of the source media?
What preset are you selecting for the Facebook upload from within the program? If you export your Timeline to a .mp4 file and then upload
that file to Facebook at the Facebook web site, are you still viewing a blurred video? If that is the case, what are the exact export settings choices
for the file export for later upload to Facebook at the Facebook web site?
Let us start here and then decide what next. If you have questions or need clarification on any of the above, please do not hesitate to ask.
Thank you.
