I have keyed out the greenscreen and started to drop the background elements in for the test, however the camerawork is beyond any post-production miracle. This has hammered home the point that its important to get it right 1st time on camera, and maybe also that the best form of control in a test is to do everything yourself including the camera!
* one shot has a part of the background not covered by the greenscreen in-shot - I cloned a part of the replacement foreground over the mistake which makes it slightly misaligned by millimetres
* the camera is unsteady and constantly shaking and moving the shot = I attempted to motion track the keyed out footage and the background image together constantly repositioning it to rectify the bad camera work, but the result is still sub-standard.
* because the camera was not being white balanced between changing positions or the changing of lights the colour of the puppets skin tones & the greenscreen change between certain shots = I did a curves adjustment in the colour correction menu in an attempt to match up the different colour shades however this made only marginal difference.
* Also because of the bad lighting there was slight shadowing round the puppets outline, keying became difficult to get to be incredibly accurate = I had to trim and feather the outline between the green background, shadowing and the actual puppet this led to slight bleeding-in between background & props/armature
