The YouTube transmission is just as clear as my original. I exported it to MPEG-4 format at 1980 x 1200 pixels. It took 30 minutes to prepare the 33 megabyte file that plays in only 19 seconds! The upload to YouTube was very quick at under 10 minutes. Not trivial to create, but it's worth the effort.
Compare to the previous version uploaded directly from the camera: au.youtube.com
