I've been playing with voodoo (motion tracking, not the black arts) for a while now, trying to get a decent track in hit film. Now when I export an avi file all I get is my imported image, there is no background plate. When I switch the background file to 3d, my imoprted image is behind it in the 3d view, although in 2d it is visible, ontop of, the background clip.
RADEON 5770, so it shouldn't be a problem there.
Also i can still only open hitfilm when I run as administrator, when I double click the hourglass comes on for a second or two then gives up.
