Thank you Dave, Bret, Walter and Rob, your help was very much appreciated.
My footage looks a whole lot better now! Firstly, I didn’t have the QuickTime ‘use high quality video setting when available’ box checked… secondly, when I put the footage on a DVD a watched it on the TV it looked fine, and thirdly, I will definitely have a play around with the ProRes 422!
Thank again!
Aubrey.
