If I recall correctly, it takes a while for a YouTube upload to get "processed" by YT before the picture looks good. They may have changed this since I last uploaded which has been a while.

Also check you playback setting on the actual YT page, a little gear thing at the bottom and se if it is playing at a decent Res i.e. 720p

Yes you are correct YT takes a while to process depending how big a upload from minutes to hours.
This is not the problem. As for viewing settings same.
Thanks for the imput.
