Here's the Edirol V-4 Vision Mixer:-
As the team set up the equipment I took notes and made a floor plan so that we could easily replicate the set-up for the event.
Naomi, our technical demonstrator, was very helpful with setting up the green screen explaining things like the importance of making sure the green material was as flat and stretched as possible and that we set up the lighting in a way that eliminated shadows completely. At this point it became clear that we would need to use two lighting kits, one to light the green screen and one to light the subject.
One of the only problems that was encountered was connecting up the vision mixer to the widescreen tv in the gatehouse. at first we didn't have the correct cable but once we realised which cable was needed (S-Video to Component) we were able to get the imagery shown on screen. This caused a bigger problem: The image coming from the laptop was extremely pixelated and no matter how much we manipulated the laptops resolution the images still looked extremely blocky.
The results looked like this:
There is still an obvious green outline around me!
I spoke to Richard who assured me that because the widescreen television was HD the imagery wouldn't be able to match a suitable quality and he expects that the monitor we use for the rehearsal will provide a sharper image output.
I thought that the demo went well apart from the problems with image quality which seemed to get the team down a bit. Hopefully the monitor we use gives a better image.
I will have to type up my notes about lighting for Will and get some photocopies of my (extremely bad) floor plan:
