Thanks, it all works brill.
Having pure black allowed me to add images as a slide show back-drop, the one thing though was that the eyes and mouth (talking and blinking) allowed for the picture images to show through, including some motion clips.
This took me a while to sort-out, I tried to create a mask to prevent this but at 30 f.p.s it was taking too long as the footage was 1hr 45min long and would have taken me a year LoL.
Eventually I figured out that if I created a re-sizeable 'Dark Brown' oval mask (picture) and positioned it behind the subject it would block the backdrop images, it worked a treat.
Thanks again
